*Roger, that!*
I currently have 3.5ton unit, but planning for 4ton unit size up very soon. What happens if I use the X72 (4ton) model to run my current 3.5 ton unit condenser?
Or, can I run a 4ton unit with the X48 model indefinitely? Wondering what was changed or found that bumped up the 4 ton units to a X72 recently.
@@danmeyo Hello Dan and thank you for your previous purchases. The dividing line between the X48 and the X72 does have some flexibility in it. There is no doubt an X72 will work on a 3.5 ton, albeit less optimal, and an X48 is likely (but not guaranteed) to work on a 4 ton. The design differences are company proprietary, so they cannot be discussed here. Thank you again for your business.
@@MicroairNet Thank you very much for such fast answer! This is more than what I wanted to hear. I can let my mind at ease knowing x72 can run my 3.5 ton unit. Thanks again
Hi MicroAir! Do you have a promo code for a fellow NJ resident considering model ASY-368-X48-BLUE for a 3 ton compressor or can I stop by your Allentown facility to purchase and say hello?
My EasyStart installation was far from textbook, after I followed the install procedure to the letter, I had a red fault light. After texting with product support, I realized my ACs wiring may have been reversed from the factory. With guidance from Roger at tech support, he was able to verify my diagnosis and provide an alternate wiring solution. These folks were patient and very understanding. Can't say enough good things about their expertise and customer goodwill!
Just a follow-up - After installing the EasyStart, I pulled the trigger on a new inverter generator. I purchased a duel fuel (gas/propane) GENMAX 9000iED. I did the break-in, converted to a floating neutral, and did my whole house test. Because of EasyStart, I can run my entire house, with all steady state and cycling loads (all lights, ceiling fans, TVs, computers, bathroom fans, 3 ton AC for the house proper, mini-split for the garage, 2 refrigerators) with no load management required. Additionally, with minimal load management, coffee pot, microwave, air fryers, hair dryers can all be run. House AC, oven/stove, clothes dryer does require load management. But the important thing is the house AC can be run just fine on the generator WITH all of my normal creature comfort's and on propane. No more bad gas/gas storage issues. Thanks Micro-Air for a terrific product.
Been thinking of doing the exact same thing. Same generator etc.
watched a very lengthy video designed for HVAC techs by this same guy about the Micro Air. It was awesome. I even understood most of it.
BTW some claim there is no data to prove the soft start kit will lengthen the life of my compressor BUT that’s not why I need it. It can’t start my 4 ton heat pump without it!
HOW do you wire for this...converted to a floating neutral...please explain
@@mikegainsley1479 *disclaimer, I'm not an electrician* I would recommend getting a generator that specifically comes designed and with instructions to convert to floating neutral if you're going to connect a portable generator to your house. If it's not designed for it, it's probably not a DIY type thing and you have to reeeeally know what you're doing. I got a Westinghouse 11500 that comes with instructions, all you do is disconnect a wire and put a new sticker.
@@Benjamin-rq1fiWhere did you find the Westinghouse 11500 tri fuel in stock?
@@JetFire9 I got it on Amazon around July 9th before it went out of stock there.
I also agree What an excellent video!!! , thank you for taking the time to make this video
I installed an ASY-368-X48-BLUE on my 3 ton A/C unit last week. I’ve been in the HVAC business for over 40 years. I’ve seen a lot of changes to the equipment over the years but the Easy Start has been one of the best ideas in years. I haven’t liked the way the compressor started since the day I installed the system. It works fine but is noisy on startup. The kind of noise that makes you think, “That has to be shortening the life of the compressor”.
The Easy-Start was extremely easy to install and there is no change to how the unit is operated. A customer would not see any difference in the way they use the system. The compressor starts quietly now and the startup amperage went from 83A to 25A. Awesome!
Thank you so much for making this device.
Your presentation was professional, clear, well thought out and easy to understand. You stayed on topic and did not wonder off into other topics only then to 45 seconds later return to your main talking point. That Bluetooth APP is wonderful. What a great product you're installing. Thank you.
Excellent video! Thank you for the information on EasyStart.
Just ordered! Thanks for the great info.
I really like my Easystart. Had an electrician install it when he did my generator hookup to my service panel.
Installed mine today/ It worked flawlessly off the bat.
What an awesome product Matteo. I’m seeing ~66% decrease in LRA in-rush current and no more loud buzzing sound on startup! Nice work.
Just completed my install. Couldn't be happier! I love the Bluetooth. Can check the status from inside my home, by a window adjacent to the unit. Thanks again!
Watching this video helped me install my easy start. The manual talks about a yellow wire but no mention of a purple wire. Anyway this video helped me to complete my installation with confidence that all was well. My unit is a Raheem 5 tons and rated at start amps of 144. My clamp meter could not capture the start amps but now I am at 2 learn starts, With a peak of 51.3 and live at 11.6.
Impressive little device! I'll be putting one of these on our new house.
I’m a believer in this technology. I installed one of the units on my RV rooftop AC units and was able to run it on a 15 amp garage outlet. Now looking to buy one for my home AC and new Camper.
Best thing I ever bought. Working flawlessly for 10 months now. 26 starting amps on my 3 ton and 9.6 running. Easily turns on a/c unit with my 12kw generator for whole house a/c during hurricane Ian.
7/22/2023 I installed two of them on my Goodman 3 ton ac units. From 79amps drop down to 25 to 28 amps according to the blue tooth app. These things are sweet love them thank you. I found out about these soft starts when talking to the electrician who installed our home generac generator. All these years and never knew about this item. I could kick my self in the ass. Anyway thank you hooked them up today and running great. Thanks.
I was coming to ask the sizing question that is pinned at the top. Good job in that, it seems we are off to a great start. I'm looking forward to buying a much smaller generator now so this will pay for itself on that purchase. Thank you!
I bought one a couple of months ago and installed it yesterday. It reduced starting amperage from 72 A to 24 A. Verified through the Bluetooth app and also via our Sense app. It did what it said it was going to do. Worth every penny
Thank you for the video. I used it and the PDF that came with the soft start to successfully install. Love the product!
Just today installed an EasyStart on my 3 ton unit. Locked rotor amps listed as 77, read 89 using a clamp on. Close enough. On first learning start - 44.5. After last learning start - 27.5. My HVAC guy had not heard of EasyStart before I contacted him. Said he was ordering one for his house today and will start recommending it to his customers. Now I can replace my old Troy Built 13500 with a much more efficient dual-fuel inverter generator.
Just purchased and installed my second easy start. First one was on my last home with a 3 ton ac. No issues there and worked perfectly with my generator. My new home has a 5 ton ac and the LRA label stated 157 amps. I didn't have a chance to actually test it but after the install and learn process, the peak amps on start up went down to 32! Wow is about all I can think to say. Again I should have no issues using my generator and running my ac. Thanks!
Do you have to discharge the run capacitor before removing wiring?
Did you notice any energy bill reduction after installing this soft start?
This looks great. Thanks for sharing your info.
Man this is the exact same A/c model and easy start as mine. All wired exactly the same. This never happens, thank you for making this.
play the lotto
Just installed mine tonight. Great product!
U just installed it last night and its a “great product”? U can’t make this stuff up…
@@gsftom a year on and it’s still a great product. The build quality, the customer service and the fact that it does what it says it does. All of the stuff that I was able to come to a conclusion on the first day I had it. Eat shit.
Brilliant! I've got two of these things coming (one 48 and one 72) for my two older heat pump units. This will be very helpful!
I also greatly enjoyed your discussion with Bryan at HVAC School. Your technical explanations convinced me that these devices were right for my home. Thanks, Matteo!
Did you get those installed, if so how have they been running? I also have a 4 ton and a 5 ton heat pump. My question was if I could use these on heat pumps, mine are brand new.
Just installed a 368 w/ BT on a 4 ton yesterday. Incredible difference in machine dynamics from before to after. Eliminated light dimming in the house during startup which is nearly imperceptible now from even the closest point in the house to the outdoor unit.
That’s amazing, I’m ordering and going to put it on mine!
This product is the greatest invention since sliced bread, kudos to the inventors, I have a Rheem 3 ton AC unit that had a LRA of. 77 amps and 12.5 amp normal run for fan, after installing the micro air 368 easy start, I went from a LRA of 77 amps down to 24.2 LRA and normal fan run down to 5.4 amps, just completed a test and was able to start the AC with my 7250 W Predator generator
Have you seen any changes on your electric bill?
Perfect, great explanation, this is why I was sold and will buy one today .20:31 - EasyStart Benefits while on Utility Power
one last question, the specs on this generator, 7500 Running Watts and 9500 Peak Watts; is this ideal for my environment?. All I need is the AC when power goes out, plus one refrigerator and one freezer in the garage. Or should I consider a 9500 Running Watts and 12500 Peak Watts. The difference in price is about $300.
Great video and product. Thank you for sharing your invention. Definitely like this for my next off-grid project.
Your instructions helped me out alot, thanks 😊 just had mine installed today
You’ve sold me on this! Where I live in Florida we experience a few power interruptions each year and even though I have a 5500K generator I can’t run my 3 ton unit. The money I spent on a window shaker to use in those times I could have purchased the Easy Start and use my split system. Your explanation was very educational. Thanks
Have you tested the product with your generator?
Nice video. I just installed the EasyStart 368 and it's working well. They only issue I had was connecting the app. There's no documentation telling you what to type in for the Bluetooth ID connection. I finally found another video on RUclips that tells you to just type in "EasyStart_" then press the Connect button. The app will find and connect after that.
I appreciate the video I’ve just recently ordered a micro air easy start for my residential condenser.
Maria: Thanks for coming on board as a customer! What is/are the reason(s) you elected to add EasyStart to your residential air conditioner?
I wanted my compressor to last as long as possible. I also wanted less Amp draw at start up to lower my electricity cost. I wanted to run a smaller generator during hurricane season that doesn’t take as much fuel to run per hour due to higher amp draw. I believe I will also like the Bluetooth capability so that I can Monitor my AC consumption. I first heard about it from a friend who installed it on her RV and started to use a smaller generator off grid.
What an excellent video!!! I have a 4ton Carrier unit with a LRA max value of 117. I’d love to be able run my A/C on generator power. Knowing that my wife and kids are home, safe, and comfortable during a natural disaster (like our FL hurricanes) while I can’t be there (First responder)is a great peace of mind. I look forward to getting one of these soon and installing it behind the access panel. I wonder why more AC installers/technicians don’t offer to sell these units as a add-on item? Seems like this would be a great option. Again, great video, well spoken and articulate demonstration.
*Florida man also here: They'd rather have it prematurely die and sell you a new Obama-approved, max-profit system.*
Great video, I'm looking to purchase and install one of these on my unit.
I installed both of these today on my 4ton and 2ton compressors and let me say, they work and do exactly what they say they do. The 4Ton Unit went from around 95-100 amps on start down to 39.4. The 2ton went from 58 to 24.3, absolutely amazing. The compressors are quieter, and start more gently. I can easily start both on my 24kw whole home generator now without any bogging down or lights flickering. This product is well made, and does what it is advertised to do. Took me 2 hours to install both, I have a bad back so I took about 45 mins worth of breaks, if I was myself from 30 years ago this would have been a 30 minute job to install 2. Very easy to install and well worth the money spent.
I ordered my EasyStart Home AC. For my 5 ton Lennox air conditioner. Can’t wait to save money. Thanks.
Matteo, you are obviously very knowledgeable on all things AC & electrical and these amazing soft start devices. Excellent video and explanation. Just bought the x72 Blue for my 15 year old Rheem 4 ton unit. Not for the usual use-case of needing to run on generator power or on a solar inverter, but to hopefully give my compressor an easier start to extend its useful life and hopefully delay the inevitable.
You can also just buy a hard start assist kit for 20-50$ which would do the same thing. This 370$ device really isn’t necessary at all. Especially if you aren’t operating a generator. Call your local hvac company and just have them install a hard start kit.
@@brandonstephens1447 Thanks for the info, I was originally heading in that direction, however my local hvac company quoted me $375 to install a hard start kit! So, I decided to do my own research on the subject. I’m an electrical engineer and handy with electrical things so I initially bought a 5-2-1 hard start kit myself but decided against installing it in favor of the easy start. The last thing a functioning compressor that’s older needs is additional torque and a voltage kick (unless the rotor is already locked and unable to start then a hard start may be necessary). The easy start is a lot more gentle on the compressor’s internal components at startup and hence my decision to install it instead of a hard start.
This is awesome!!!
Great video. Really helped me out setting up my X48 for my home's 3 ton AC unit. You can't live without AC down here in Florida. My Great Comfort AC unit did not match the diagram. I suspect the previous owner made modifications. But went from 44 peak amps on first learning mode to 25 peak amps at final learning. Just enough that I can run it off my generator now in case of power outage. I suspect the capacitors on my AC are junk. Main cap is a cheap one. And second one is leaking cap juice. I'm gonna swap both out and have it re-learn after the swap, see if it goes even lower. Thanks!
There should be just one capacitor. The other unit you have maybe a hard start or some option. You need to read about it in the detailed installation instruction. Contact their tech dept for appropriate actions for your case.
I love my EasyStart - I have the ASY-368-X72-BLUE for my Trane 4-ton unit. Before EasyStart - Peak Current Inrush = 133.9 Amps / After EasyStart = 35.5 Amps Running amps 16.5 I am very happy with the EasyStart and find it well worth the money. Thanks, Guys!
Great video, very informative. Excellent choice of background music during wire splicing!
They work great for us solar off-gridders. 6.25 Ton of heat pump total capacity.
that's a lot easier to see than the convoluted install instructions online. For a safe installation also it is super critical to shutoff power to the compressor and the inside unit as it sends 24VAC to the outside unit where there a demand for the compressor to run.
Due to your video I bought a Micro-Air EasyStart for my 3 ton A/C unit. My standby gen of 13KW is now way oversized, but means we don't have to economize much in a power outage situation. Thank you for a great product.
11:00 Excellent choice of music!
The best starting device I have ever seen in my 40 years as an AC Tech! I would advise to checking your uf/ microfarads with a meter on the existing capacitors and see if they are up to the manufactures value. All capacitors lose value over time and age with usage. No system should ever be close to let alone exceed LRA. Locked rotor amps. I have always installed starting devices on new equipment, because it gives longer life of the compressor. It's controversial over the term easy start or hard start. They both do the same thing with a large capacitor and potential relay in the circuit. All Trane units are designed with these and some others as well. But most do not incorporate this technology. I do not recommend using a second device on a system with one on it!
Hi and thanks for your comment. As it turns out, hard starts and soft starts are TOTALLY different. Hard starts are nothing more than a start capacitor with a switching device. EasyStart is a very sophisticated, microprocessor controlled soft start device that orchestrates a complex, closed-loop electronic sequence via high-voltage and high-current semiconductor devices to gently ramp-start and accelerate the compressor with up to 75% reduction in starting amps. For further details and deep dive into the differences, please check out the video at this link: ruclips.net/video/7Gim96oyczw/видео.html
Two additional recommendations. Scroll compressor slurp up an initial larger amount of oil on initial startup. You should allow compressor to run a minute or two to disperse the oil initially sucked up into compressor head. Several short start-run cycles can log too much oil in compressor head causing oil slugging on compressor.
When mounting EasyStart in electrical compartment it is a good idea to check the sheet metal screw clearance on back side of sheet metal. Driving a too long sheet metal screw into condenser coil will give you a very bad day causing a refrigerant leak in condenser.
A little late to the Micro-Air party, but living on the Gulf Coast of Florida with the forecast of a robust hurricane season, I had our Micro-Air installed earlier this year on a 2014 3.5 ton A/C unit. Hooked up my DuroMax 9000iH generator today (sister-in-law and hubbo live in Houston and are 5 days into no power) and thanks to Micro-Air, and DuroMax, I ran the A/C, Fridge, Ceiling fans, outlets, etc., without a hiccup. Very cool to have the generator running, turn on the A/C, hear the generator surge for a second and then having full A/C on a very hot, humid (heat index of 104 today) day on the Gulf Coast. THANK YOU Micro-Air for this video and your product!
And just to clarify… today was my first test of the system. Didn’t need it yet, but relieved to know it all works- thanks to Micro-Air…
@@cliff9745 - Who Installed of for you? I'm on the gulf coast as well and NO one has ever heard of this
@@PureBlueAgave Good morning- I reached out to my electrician. He’d never heard of an Easy Start, but he sent 2 guys over, I gave them the installation instructions and they got it done with no problem. Dramatically reduced A/C start up amps. They said they can’t figure out why every A/C doesn’t have an Easy Start.
Wow Great vid info and product! Cant wait to understand if this saves me money on electricity while on utility.
Just asked my AC tech about soft starts yesterday .He said he didn't know much about them except they were used on solar installations .
It was easy to install, works Great. I bought it for my generator to run to house ac (9000 watts peak with 7200 running). Works great I would buy it again.
Excellent Video.
Verry professional explaining thanks
Hello, just purchase my EasyStart 5 ton unit Oct. 2022. I had all the crimping tools and connectors to install it already. My 15 year old original Westinghouse compressor made a loud bang! noise at start up every time it came on. The inrush current exceeded its limit. After installing a hard start kit the inrush was below it limit, but still BANGed on start up. Once I removed the hard start kit and installed Micro-Air EasyStart 5 ton model the compressor. The compressor fan starts up first and after about 10 seconds or so the compressor starts up Ever so quietly. You almost don't hear starting. From Inside the house it would startle me with each cycle start. Now it is whisper quite inside the house house. I hear the compressor fan more than anything inside the house - no more scary bang ! Worth every penny. My hope is this will extend the life of our A/C unit. It would be nice to have the actual wiring schematic drawing beside the photos on line. So between the online photos and the verbal instructions on this video, I was able to figure out the wiring. I used a variable drill bit to drill a new hole in the electrical box and an external wiring connector to go through my electrical compartment as the EasyStart would not fit inside. 4 self tapping sheet metal screws to mount the EasyStart outside, and done. When the old compressor is at its end of life, it can just be transferred to the new compressor. This is something they should point out, added value that it can be used on your new unit, and you don't have to buy another one. Thank you for the great product video.
p.s. After the EasyStart install, I can easily start and run this 5 ton compressor from the Tesla Solar inverter and Powerwalls without any startup assistance from the grid power!
Glen - Thank you for your comment and for your business. Yes, if you ever did want to move the EasyStart to another HVAC system, all you have to do is re-initiate its relearn process via the app.
About a year ago I successfully installed (on the 1st try) an EasyStart on my 2 Ton & 3 Ton A/Cs, and one on a neighbor's 3 Ton A/C. They've all work great. I am able to start and run both my 2 & 3 Ton units using either my fuel injected Honda EU7000is (running on gasoline) or my carburetor fed Harbor Freight 9500W (running on natural gas). I use my much, much quieter Honda only at night, while during the day I parallel my Honda EU7000is & HF 9500W. Paralleling is only possible because both generators are inverter type, 220 Volt AC, with 2/3 pitch windings. When running only 1 generator I must always sequentially start my 3T first followed by my 2T second to prevent generator overload shutdown. Even though my 2T & 3T units are side by side, one generator is located next to & connected to the 3T, while the other generator is located 200 feet away connected to my main AC service entrance panel. I converted both the Honda & the HF generators to run on natural gas using "US Carburetion" kits but because natural gas has considerably less power than gasoline, only the HF generator can start my 2T & 3T units while running on natural gas. While running on natural gas my Honda EU7000is can start one A/C but not both. Since my natural gas regulator low output pressure is 4 psi, I used 2 parallel 3/4 inch diameter flexible hoses to connect the regulator output to the generator located 200 feet away. Using parallel 3/4 inch hoses is much cheaper than a single 1.25 inch diameter hose, and the 3/4 inch hoses are easier to store when not in use.
Even though I had to mount the EasyStarts external to all units due to inadequate internal clearances; I wondered about your video's recommendation to install them within the A/C compressor/condenser contactor/capacitor metal box.
I noticed that I must be within 20 feet of the externally mounted EasyStart units to get the Bluetooth app to connect. If I had mounted the EasyStart within the A/C contactor/capacitor metal box, would that have reduced the Bluetooth transmitter/reception range?
Hi Rex. Thanks for EasyStart application summary and for you business. Regarding your question, when the EasyStart mounted inside of a typical outdoor condensing unit's electric box, our testing shows that a typical smartphone will get about 20-30ft of Bluetooth range when within line of sight. Around corners and through windows, the range is obviously less. Any grounded metal enclosure does act partially like a Faraday Cage, so putting any radio transceiver into a metal box will of course reduce the reception by a varying degree, depending on the design, shape, and material of the enclosure.
@@MicroairNet , has your company considered other way to extend the transmission range? (offer an external antenna that one can mount remotely or the technology some WiFi devices use whereas the transmission is coupled onto the A/C line wiring ! (This would bring the range easily indoors !)
@Douglas Montgomery; Micro-Air has not considered methods to extend the existing Bluetooth transmission range since this access is only meant for as-needed diagnosis and upgrades. However, in the future we are considering adding Wi-Fi connectivity, which might allow for the EasyStart device to connect to the home's Wi-Fi network (rather than directly to your smartphone). This would then allow you to access the EasyStart from any other location where your smartphone was still within range of the same network, thus significantly extending the range.
@@MicroairNet , Wifi..PERFECT (like my Nest thermostat) !. Thanks !
@@douglasmontgomery6315 yes. WiFi would make it another Game Changer
nice presentation
looking into to buy one for my 2.5 ton home unit
thanks
Just ordered my 368 will determine what size generator needed. Thank you much.
Thank You, it was a great video explaining all the details. I plan on purchasing one shortly. I have an old 5 Ton Trane 36 year old AC and I'm not quite able to purchase a brand new one just yet. My electric bill over $900.00 dollars. I hope that this will reduce my electric. Of course the electric company is price gouging when the country is in despair. Thanks again
Hi and thanks for your comment and for your business! Just to make sure this is clear and you are not disappointed, although EasyStart will dramatically reduce the startup current spike that your compressor draws during its first second of operation, EasyStart does not affect the compressor's current and power consumption during steady-state running. Therefore, EasyStart will not reduce your kWh consumption (i.e. energy use). However, if you live in an area where your electric utility charges what is know as a "demand fee" for peak power consumption during certain (high-demand) times of the day, then EasyStart would reduce and perhaps even eliminate those fees. I hope this makes sense.
Try cost justifying investing in some solar panels with a 5 to 11k inverter and if you can afford it, some backup batteries. There are Federal and some States have Tax credit incentives to help with the costs. Over time reducing that $900 bill will pay off. Avoid financing where they put a lean on your house. Some dealers call it something else but its a lean. Either pay cash or get a conventional loan or a home Refi line of credit. Also, as a low cost option, having upgraded insulation and attic fan could help a bit as well.
Hope that helps.
@@capobiancg l live in Las Vegas, NV. I installed an attic fan and remote wireless thermometers in my attic and outside under the eaves always in the shade. I wanted to document how well the attic fan worked.
Much to my surprise, my attic never got as hot as the outside air, was always cooler, even at 5pm the hottest time of the day, even during weather alerts and warnings for extreme heat. 🌞
So, I never turned my attic fan on. Why would I want to replace cooler air with hotter air?
This totally surprised me. I just ignored the attic fan. In hindsight, obviously, I wish I had benchmarked the air temps before buying and installing the attic fan.
This looks like a great product. Soft starts are the way to go. Besides limiting current spikes, it should also lengthen the life of not only the compressor but of many of the parts of the system. Maybe you could develop a sister product that works with the blower fan(s).
Don't need one for the "blower" as most condenser fan motors / evap. motors are ecm and or x13 motors witch use 3phase vfd/inverter witch is what the easystart is for the compressor.
@@goodoleme most outside fan motors are not efm. They are powered through the other side of the dual capacitor. They draw less than 2A when running. They don't have the resistance to start moving as the compressor does, so it would be surprising if their start current was more than 10 A. With the easystart starting the fan a few seconds before the compressor than there would be nothing to gain to duplicate the electronics in the unit. The peak surge current still remains the compressor but at 70% lower value than what it was before.
As far as running it with a generator it is actually better that the fan starts a few seconds before with normal in-rush current as that gets the generator speed increased to handle the spike on the fan motor so by the time the compresssor current spikes the generator is already reved up from the previous spike.
No one would buy it as the savings on the fan in rush current would be very small . Besides the easy-start unit starts the outside fan a few seconds before the compressor.
@@didyuknow ...And many of those ECM condenser fan motors are changed to old-school PSC induction motors, once the customer finds out what the replacement ECM motor is going to cost. 🙄
Mine just came in today. Installing it this weekend. I have a 8000 starting watt generator. It struggled to start my 3.5ton trane unit. I shut it off immediately to not harm anything. I was bummed out to see how inflated 10K plus generators have gotten. You could buy 2, 5K units for less than 1 single 10K, wilddd. 2 years ago a 12K was right around $900, now its close to $1,700. I found this for under $400 perfect solution. My A/C unit only draws 4200 watts after it gets started so with just a couple Tv's and Ceiling fans my Generator shouldnt ever be over 75% utilization. My home is very VERY well insulated so even in the harsh summer maintaining the house at 70f it never runs more than about 8hrs a day.
Thanks for a very helpful video. I installed my new EasyStart a little over 2 days ago using this video as a guide. My inrush current went from a measured 74 Amps to 25-28Amps as reported by easystart. It is operating in the Arizona heat, over 110deg. Since install, the compressor has run 146 times as reported by the app. One odd thing: The very first start after install resulted in a fault, and a red led. No big deal, this quickly cleared on the next start, the unit completed the learning process on subsequent starts, and it ran the rest of the day (installed late morning) and overnight without issue (some 60 starts, fault count 1). Sometime the following morning, the fault count reported by the app increased to 4 (3 new faults). I never saw any red led display and the unit always seems to function fine. The following morning, the fault count increased to 7 (3 new faults), again with no sign of any problem with the unit or the operation of the system (that I observed, you can only stand out in 110deg and watch the unit cycle for so long). Anyway, EasyStart seems to be working well, but I have no idea what these faults might indicate or if I should care. It will be interesting to see if the fault count goes up by another 3 tomorrow morning.
Hi David and thank you for your comment and for your business! EasyStart has many recoverable faults, like those that may be caused by very brief power interruptions from your utility. The fact that EasyStart recovered and kept going means all is likely fine. If however the fault count becomes excessive and you are concerned, please feel free to upload your EasyStart's data to Micro-Air using the Diagnose screen in the app. A support person will analyze it for you and let you know what is going on.
@@MicroairNet Thanks. 2 additional faults this morning, seems to be something that happens at near the same time each day. I don't think I'll worry about it. I am now up to 196 starts and it's working great.
@@davidwolfenbarger7383 how old is this unit??? It could be the old CONTACTOR is in in poor shape and on its last leg.
Take the time to order spares while the unit is running and before maintenance turns into an emergency repair.

@@MicroairNethow long do these easy starts usually last. As well can I install them as an ad on to all my new installs
@@jasonrhoades9270 Hello Jason and thank you for your question. The EasyStart is designed to last the life of your air conditioning unit. You can even move it to a new unit, and reinitiate its first-5-start learning process. Yes, you can install them as an add on to all of your new installations.
Great video
I saw a video on YT from Gavin’s Garage and he installed a Easy Start. He has a 5 ton Carrier AC and powered it with with a Honda EU7000 which as (5500 running watts) and it ran fine. He also started the 5 ton unit with a Powerhorse 7500 watt (6500 running watts) and it also ran fine. I assume he would only be able to run the A/C unit only and nothing else on those 2 generators.
AC units have a dual capacitor, one is for the compressor (herm) and one for the fan. There is no switching between starting and running so its neither a start or run capacitor its just a capacitor that creates a out of phase line so the motor will work on single phase.
you are right about phase shifting a second winding. If there is no switching and cap stays in circuit for both start and run than it's a normal run cap, right?🤙
Installed the unit on my 3 ton Bryant AC/heatpump. No issues with the installation using this video and the downloaded instructions. I also used the connectors kit which for 12 bucks is worth it. According to the Bluetooth app my new inrush amps are averaging 26.5 with a running amps of 7. My bryant manuals say their avg is 76 inrush and 16 running. I'm letting it run all weekend and next up is the test with my a-ipower 7100 generator. There is no noticeable decrease in sound upon startup (actually, now my compressor 'thumps' upon startup) however my primary purpose is to run off gen power....
*next day update*
I successfully ran my a-ipower 7100 using the easy start today. I did 5 starts of my ac using the propane power which has a reduction of load to 6400 w peak and 5100 running. My generator handled the load quite well, both at high speed and econ mode. Average running load on my generator display was 3000w, which was the ac running (again, a bryant 3 ton unit) my GE refrigerator and all home lighting, etc. The BT app showed a inrush amps of 23 avg and running amps of 6 avg. I'm really happy with these numbers as I can run in eco mode and save fuel.
Tank you brother..
OOOO Matteo!!!! Nice vascularity!
Heavenly LED lights inside to tell the condition of the unit sounds like you need to mount it on the outside of the unit so you can see what the problem might be rather than inside
THANKS !
Before installing EasyStart on my ancient (15 year old) 4 ton Rheem compressor, LRA inrush measured at 123 Amps. After installation and the prescribed 5 learning starts it has dropped to 38.1 Amps. 69% reduction! Not planning on using generator power as our power here in Oregon almost never goes out. Hoping this keeps the compressor working for a few months or years longer. There wasn't enough room inside the electrical box area of the compressor, so I've attached it to the outside of the housing with neodymium magnets :) The casing is rated for outdoor use so should be ok is my understanding.
Im not electrician, but seams to be a great gadget.
Just ordered two of these for my 2 and 4 ton AC units so i can take the strain off of my Generac 24kw whole home generator. The 4 ton is old and pulls 117 amps during start and the generator runs it, but it bogs down hard. These should eliminate the bogging and the lights dimming on generator.
I used tarp elastic bands with hooks. My EasyStart did not fit inside. I did not want to screw into cover because every time you service AC unit the cover is removed and placed on the ground.
Just got my Soft Start today for my 5 ton. I’m going to DIY it this week. Everything makes sense, except the top of the capacitor. Hoping it makes sense when I take a close look. Black - L1, white - L2, brown to compressor (spliced), orange to top of capacitor (I think the HERM terminal).
Hi Willie and thanks for your business! Yes, you have it correct. As I mentioned in the video, be careful not to connect the EasyStart's ORANGE wire to the wrong terminal of the run capacitor, especially if it is a "dual" run capacitor with 3 terminal clusters. The compressor's start winding connection is always on the "HERM" terminal of the run capacitor, as you already mentioned. That is where the EasyStart's ORANGE wire should also be connected.
Regading the EasyStart's BROWN wire, that will be spliced to the run winding wire (whatever color your system's internal wiring uses) after you disconnect this run winding wire from its contactor terminal (typically labeled T2 or T3, which is the switched L2 output of the contactor). In place of the run winding wire will go the EasyStart's WHITE wire on the same contactor terminal. Then you splice the freed run winding wire all by itself to the EasyStart's BROWN wire. Hope this helps.
Just installed mine and the LRA was 77. After 5 starts it's 23 amps. A 70% drop in current on a 3 ton ac. Running current is 7 amps. Hopefully it'll drop the electric bill a little. I installed it so I can run my home ac using two EcoFlow Delta Pro's.
I bought One .
You should really highlight the brownout, over voltage and power interruption features of the EasyStart in your literature more. This protection is why I bought your brand over others. Utility power isn't as reliable as people think and it is very hard on compressors.
Just installed the EasyStart X48 on my 3.5 ton Rheem AC. LRA dropped from rated 109 down to 28.1 after 5 learned starts. Very happy. Anxious to hook up my generator through an interlock 30amp breaker to see if it will actually run the AC. Could be close with 6250 running watts and 8500 starting watts. Have to wait and see.
So how did it go?
I'm curious too. I have a 3.5 ton and a B&S 6550 storm responder generator. Really curious if this will actually work.
DUDE is fkn SHREDDED !!!!!!
when he did the momentary power loss test the amp meter was still indicating a current draw of 19 amps the same amount as in normal mode. SO looks like the box allowed the compressor to start again without a delay.
The custom ammeter was doing a peak capture, thus it never changes its readout until deliberately reset by pressing a particular button.
Than you for getting back to on the Pool pump application. SaD, that it can’t be done. As I am in the process of purchasing 2 EasyStart units for my 4 and 2 ton AC units. Can I also use the EasyStart for the blower motor?
Hi again Pablo. Thank you very much for your business. You will be very pleased with the huge startup current reductions you will enjoy on your 4-ton and 2-ton A/C units.
Just to be clear, the pool pump *can* be outfitted with an EasyStart, but Micro-Air does not have the resources to support such an application. If you have the necessary knowledge and you know your pool pump's internal wiring diagram, go for it.
Regarding the blower motor on an indoor or outdoor A/C unit, EasyStart is not necessary. This is because these blower motors are what is known as variable-torque (unlike a compressor which is constant-torque). These motors only draw only 2-3 amps when running, and their startup current is only about 3x that. Therefore, the startup amperage savings isn't going to gain you much. Beyond this, EasyStart isn't designed to start a motor as slowly as a blower motor would require. Therefore, Micro-Air does not recommend that you install an EasyStart on a blower motor.
Installed one today on an oxbox by trane 4 ton unit. Stopped the flicker of lights in my house. I'm not sure what the initial start was, but I think the microair easy start is doing what it is supposed to do. I'll be connecting a 13k duromax generator. I'm hopeful that it will run the entire house, including the A/C. Will follow up once I have it running.
Matthew, I purchased the Duromax tri fuel recently and I am running on N.G. which reduces your wattage and amperage I have to say so far I am not impressed with the micro air 368-48 I am only seeing 38 amp in-rush amps . My surge amperage is only 35 on the geny, yes it runs it but if anything else starts at the same time I am thinking it may cause damage . AC 3 ton and is 3 years old. Just a heads up. I am dealing with Barry from tech support right now and wondering if they can explain why I am see such high amps.
I actaully installed hard start and was at 36 amp
Just Fyi
@@jeffh9288 Any update sir?
@@matthewr704 hey Matthew I got with Matteo and right now it is a work in process and going in the right direction he explained it to me as being a sliver or post stored Spike.
It's inherent to some compressors unfortunately mine is one of them and that's why I have that reading as is but he says not to worry as that is just such a minute part of it. I will keep you posted but I feel much better now knowing that
Sounds like you're probably getting the tri-fuel or just gas and propane I'm running the tri-fuel one and using it on natural gas
@@jeffh9288 also have a tri fuel running on NG. I’ll test is as soon as i get back in town!
My oxbox is brand new. 4 ton. I think the inrush was 119 before i installed. And I’m down to 42. Not sure if the generator will be able push it, but we’ll see.
Thanks for the video. Question, I have a Trane XR which has a LOT of electronic components and boards. This is a 4 ton a/c - heat pump and it affects the home lights when it starts ( 114 LAR) pull. I wanted to install the easy start but I am afraid that I will affect the functions managed by the electronic controls. Would it be the same process to install the easy start as you show on your video? What has to be done different if need be? Thank you so much for your guidance
Hi and thanks for your question. Your keen observation may in fact impact the EasyStart setup. Typically, when there is a sizable circuit board in the condensing (outdoor) unit electric box, that control will typically monitor the compressor's startup to make sure it started right after the contactor closes. The EasyStart will delay the start of the compressor by as little as 5 sec and as much as 3 min. This may cause that separate controller to declare a fault and turn off the contactor before the EasyStart has started the compressor. We've seen this before with certain Carrier units that also had big circuit boards. There is a fix for this that is accessible from the EasyStart's Bluetooth app. Other than this, the EasyStart installation wiring is exactly the same.
I went online and tried to find some good installation manuals for the Trane XR series. I found that there are various sub-models, XR13, XR14, XR16, and XR17, none of which had descent manual online. So, the best course of action for you would be to take a clear photo of the wiring diagram on the inside cover of the outdoor unit's electric box, and email it to help@microair.net. Ask the question if your unit will support an EasyStart installation and if the startup delay needs to be set to 0 seconds. There is a way to do the latter via the Bluetooth app, but we don't recommend anyone do this unless their particular A/C unit absolutely requires it. The startup delay is part of EasyStart's added compressor protection features, so defeating it is only worth doing if the A/C condensing unit absolute requires it to function properly. Hope this helps.
Excellent video. I just got done watching and installing my EasyStart 368. When I was installing, I bumped the orange wire connection and came off from the capacitor. This signaled a "wiring fault" in the EasyStart app. I re-wired and made everything tight again, no more fault. Is there a way to clear the Faults: 1 from the app now?
Hi Justin. Thanks for your compliment and for your question. The only way to clear the fault count is to do a ReLearn. We don't recommend that you do that if you are having favorable startup performance results with your original (factory-initiated) learning episode, but if you are determined to clear your fault count, this is the only way.
Looks like a great product.
Should there be a safety comment about working around sizable capacitors due to their stored energy? Maybe explain how to discharge a cap before working around one.
Hello and thank you for your comment. As it turns out, the run capacitor automatically and quickly discharges through the motor windings start-to-common-to-run after the contactor opens or the power is turned off to the condensing unit. You'd have to touch it almost immediately after power was removed to get electrocuted. Beyond this, any OEM-installed hardstart kit (i.e. a start cap) may have to be discharged before removal (as part of the EasyStart installation) if it does not have a bleed resistor (which most do). Only start caps without bleed resistor can hold charge and are potentially dangerous. Nevertheless, it is always safe practice to short the capacitor terminals with an insulated handle screwdriver after turning off AC power.
I agree. I have an electrical background so first thing turn off circuit breaker to the HVAC. Short out caps with an insulated screw driver. Also I found on my unit there is another power circuit going to the attic unit which does also provide 120volts to the outside condenser unit EVEN thought the cutoff switch is disconnected. So look into that circuit breaker as well.
I just am curious if this will save me money on the electric bill. I dont have a generator nor an RV. Just a regular house with very little power outages. I understand this will draw 70% less amperage in the startup. Will it slowly increase the amperage as the unit runs? Is this healthy for the AC unit? thank you for doing this video!
Hello and thank you for your comment. This is an often-misunderstood concept regarding EasyStart. As it turns out, EasyStart accomplishes the ramp startup within about 1 second. After that, the compressor is running at speed normally, and EasyStart has no effect on it its operation or normal steady-state current draw. Therefore, EasyStart does not save you a measurable amount of electricity (kWh). However, in some regions of the USA, there are electric utilities that charge a penalty for surges and spikes in current "demand". In these regions, EasyStart could save you money on your electric bill. Thank you again for your interest.
Man about 9:36 that’s a big lizard running across lol I had to stop and go back to make sure what it was great video for sure
Could one of these be added to an 120v air compressor to help with the high draw on startup. I think most of em have a 2 wire Capacitor
Hi and thank you for your question. The short answer is yes and no. It has been done with success in the past in some cases, but Micro-Air does not recommend it nor can they support you in the effort. Here's why.
Years ago when EasyStart first came out, Micro-Air did work with customers with air compressor, dive compressor, and HP water maker pump motors to install EasyStart. Unlike air conditioning compressors that "present" all of their wires quite easily and readily, closed-frame 1/8 to 3 HP motors do not! In fact, in order to gain access to the wiring, you sometimes have to disassemble the motor. Then, if you cannot get the motor manufacturer to provide you an accurate wiring diagram for all of the motor's internals, trying to identify the common, start, and run winding connections can be almost impossible. Isolating the run winding is also sometimes impossible. So, unless you have a detailed internal wiring diagram for your particular motor, have extensive electro-mechanical skills where you can locate and access all of the wires by disassembling if necessary, and have infinite patience and persistence, Micro-Air does NOT recommend that you consider installing an EasyStart on such motors. Micro-Air is a small company and is literally buried in production and support work this time of year, hopefully you can understand this position. Thank you for your understanding.
Would you recommend installing this on a 3ton ac unit using a portable generator 12,500/9500 watt. Or install a hard start? bc the generator has more power? I'm leaning towards a soft start since the generator will have power being drawn from other things around the house limiting how much more power that it can provide at the time of ac start up. I am under the impression that a soft/easy start is better for lower or less power generators to start the ac compressor.
Hello and thank you for your question. Even on a generator that was already large enough to start an A/C without anything added, we would recommend the EasyStart over a hard start because of the exact reasons you cited and what was also mentioned at the end of the video. With EasyStart installed, you can have more appliances running in the house whenever the compressor goes to start, there is much less stress on the compressor during any start (i.e. on generator or utility power), and there is less stress on the generator during a compressor start.
I installed the Easy Start on my 5-ton Trane XR13 (2008) A/C and, to my surprise, this particular A/C came with an OEM hard-start installed. Once I removed the hard start I found space behind the side panel and mounted the Easy Start, ran the wires into the electrical area, and found that it was very easy to make all the connections. I did receive specific instructions from the Tech Support team at Micro-Air - thank you. I have definitely noticed a difference on how my A/C performs now. I do have a couple question though - why do the values for the Last Start Peak (A) range from 35.5 to 42.3 over 48 starts and what causes this?
Hello and thank you for your comment and for your purchase. It is typical for the starting amps to vary from start to start, by up to +/- 5A. This is because of internal system temperature conditions and residual refrigerant pressures, both of which will vary depending on time-of-day environmental temperature and how long the system was off since its last operational cycle. Thank you again for your business.
The compressor draws less current if it has run in the last 10 minutes. (I have seen 70A when compressor still warm and 100A when it had cooled down after 30 min). That variation will also be noticed when you install the easy start but the numbers will be much lower. The installation manual lacks much detail and a bit confusing with too many ambiguous words. I am glad there are several videos on youtube on this subject to feel more confident .
Without EasyStart, what was the continuous run current after the initial 77amp start up? How long did it take to get to that lower continuous run current?
Hello Larry and thank you for your question. EasyStart does not change or affect the continuous running current. EasyStart only affects the startup current. The startup sequence is completed in about 0.7-1.0 second, after which the compressor will be drawing its normal running current.
Thank you for the detailed video and explanation. Your product seems very well designed. And its greatly appreciated that it is designed and made in USA. Based on your very well written documentation, Bluetooth is only activated when a call for cooling/Heating is made to the Condenser so that the contactor will apply power to the White input wire of the device. Is it possible to have the bluetooth on all the time in your future product generations? Also incorporate some application access security such as authentication requirements?
Hi and thank you for your compliments and for your question. You are correct in your assessment that the Bluetooth will only be accessible when the EasyStart is powered up via the condensing unit's contactor. EasyStart has and always will be a slave device. In order to allow the Bluetooth to run all of the time, we would have to add a fifth wire and some associated circuitry. However, in order to keep the product cost and complexity of installation down, this was never part of the design since the product's inception. Yes, we realize that customers like you could certainly handle connecting a fifth wire, but you'd be amazed how many complaints we already get about 4 wires. Also, the Bluetooth feature is only meant for diagnostics, so continuous connectivity was never the intent. Hope this helps.
@@MicroairNet I see that you already thought about this. Yes, I also have found my fellow HVAC professional often want minimal wires. :) . Great product by the way, and there is nothing else like this. The safety features and the app information is already worth it.
While the easy start can get the AC/heat pump started, I wonder how much of an issue auxiliary heat strips run during defrost cycles would be. Since getting an energy monitor I've noticed that the air handler for my heat pump goes from 500 watts to 10kw for a couple minutes every couple hours when heating. The rest of the time my whole house including the 3 ton heat pump usually draws under 7kw. I'm wondering if the heat strips would need to be disabled for the defrost cycle if on generator power without a 10kw+ genset and if that would mean physically disconnecting them or if there is a setting with the easy air or something else that could manage it.
I looked into it more and found that removing and capping the white thermostat wire from the heat pump defrost board enables the defrost cycle to run without triggering the heat strips, so no more 10kw energy requirement popping up that would prevent my generator from being able to run the heat pump. I haven't noticed any comfort issues without the heat strips during defrost but it would be easy to reconnect the white wire if needed.
Great directions. I installed it today. I spent more time on the bluetooth connection than on the actual installation. 5 stars on the product. 1 star on the bluetooth. There was the oddest coupon in the box. "If you bought this on Amazon, you paid too much." Weird.
Hello and thanks for your comment and feedback. The coupon you mentioned definitely did not come from Micro-Air, so we'd like to investigate that; from whom did you purchase the EasyStart? Also, what was it about the Bluetooth connection that you did not like? Thanks in advance.
@@MicroairNet I tried to call but the automated answering system gave me the online options then hung up. Do you have an email address?
@@flyingjeff1984 Yes, you can send an email to help@microair.net.
How well will the Easy Start function in the AZ heat?
I tried a Sure Start and it would not function properly above 90 degrees.
Hi Richard and thank you for your question. EasyStart is specified to work in ambient ("desert") conditions up to 50°C (122°F), but it was designed to go beyond that. It has proven to function well up to 55°C (131°F). Many of our 70,000 RV customers have taken their EasyStarts into some of the harshest desert conditions imaginable, including some in the Australian outback, and EasyStart was able to handle them.
I have my ASY-368-X48-BLUE running for a little over a year now on my 2.5 ton heat pump, it brought compressor LRA from 57 amps down to 20 amps nominal. About 3 month in the run capacitor started to fail causing the run current to increase over time. The EasyStart detected the abnormal operating current and went into fault mode to protect the compressor as it should. Looking at the bluetooth app live data was able to point me in the right direction on troubleshooting the fault and saved me a $125 service call plus a $20 part.
Not sure on how much internal memory the unit has; is it possible to see what fault in more detail in history pulled from the app besides just a number(s) detected? I understand that most general users may have no interest in that level of detail, but for those who are data nerds like to know what the fault is and if I need to dive deep into the rabbit hole or not. It would be a nice feature for a HVAC tech since it will give them a better insight what is happening electrically with the compressor.
Hi Felax and thank you for your keen observations and great use of EasyStart's fault detection to find your bad run cap. This happens a lot, as I'm sure you can imagine.
If you ever wanted more detail on your fault history, please upload the data to Micro-Air using the Diagnose screen, then when someone replies to you, ask them to send you a summary of the fault history. There is a lot of information in each fault capture, so from this the Micro-Air team can determine a lot of what might be going on.
Can you do a video of installing one with with the extra board? I have an extra board inside my AC but it's a trane and I can't tell exactly what it is.
Hi and thanks for your comment. We really wish we had the resources to do more videos, but the sheer quantity and variety of home A/C systems on the market would make such an undertaking almost impossible. But do not despair as there is good news for you. The Micro-Air Customer Service team has helped thousands of customers like you with their specific A/C system requirements, including explaining the connection points, making custom wiring diagrams, making custom picture diagrams from photos, etc. The best thing for you to do is take some clear, high-res photos of your outdoor system's dataplate label, the inside of its electric box (including the control circuit board you spoke of), and any wiring diagram that is on the inside cover of the electric box. Send these photos to help@microair.net, and they will be able to advise you as to where the EasyStart will wire in. In almost every case, any control board and its wiring that may exist inside of a system's electric box like yours, will not be touched or altered in any way, as part of the EasyStart installation.
