4-5 ton Mr Cool condenser replacement. I used my existing air handler. wanted something quieter something better when it gets cold and better on energy.
Finally got my 4-5 ton MrCool running yesterday south of Buffalo NY. Was about 18 F yesterday and the unit worked great. In my case, I put a new Rheem 95T 70k BTU Propane converted furnace in and topped it with a 4 ton MrCool Coil. Had mice build a nest in my outdoor unit - looks like they got in under the service valves where the cover tab was broke off. No chewed wires luckily but I need to keep an eye on this. I covered the hole and put a stick of rat bait on top of the compressor. Thanks for making this video. This should be cheaper to run than propane - my propane cost went up 40% over last year. Have the propane furnace set to run as the "heat strips" and emergency if the heat pump can't keep up.
I just installed a pioneer 4 ton system similar to this, really like how quiet it is compared to my old goodman. My only regret is I didn't do enough research beforehand. I should have gotten one of the brands (aciq, blueridge) that use a communicating thermostat, so that the unit didn't have to cycle on and off. instead it would just throttle down the compressor to match the exact cooling demand the house needs to stay at the set temp and stay running at that low speed continously. I can definitely feel when the pioneer kicks on and off inside my house in terms of temp change... oh well, still light-years better than that goodman that was undersized for my house.
I agree. The communicating units are great. Most of them require you to have a certain thermostat . And they're usually a lot more expensive.. this is a great option for if you're just changed now at the outdoor unit.
@Michael Melnichuk Aciq and blueridge were both cheaper than Mr.cool and the pioneer I got. I can't speak on the quality of them though, thats the main reason I picked pioneer since they have been making inverter ACs for a long time.
I think its compressor speed is designed to run at a constant campacity output, or maybe on some type of relationship with the outdoor temp. such control can not be seen outside the north american, because people use wired remote controllers else ware so indoor and out door unites communite with each other like mini-split and campacity is controled by the difference between set point and indoor temp.
No. What it does is when it receives a call for heat or cool, it will start at its lowest capacity. As time goes on, it will ramp up capacity until the call for heat or cool is satisfied.
@@sprockkets Thank you JM M. You are obviously an experienced well verse HVAC pro. I retired from the HVAC residential service business in 2000 here in Northern California. Just learning about these new residential Split system VRFs that advertise varying capacities in 1% increments. back in my day, we thought 2 stage scroll was high end. Do you have any thoughts on the Bosch IDS series as a comparison?
@@TheRealoldcar unfortunately no. I keep up with the trade but don't work in it except setting up 4 mini splits in the past 2 years. In not sure who makes the bosch. Maybe they do. What was interesting is that pioneer sold them for 4 years. Same unit.
This is a great idea! Does it the outside unit connect and communicate properly with the inside air handler using just the standard thermostat wire? I thought these required a separate, direct, higher gauge connection between the compressor and air handler. My system is only two years old, but the outside unit is bad. I bought the system used, so it's not under warranty. (Bad reversing valve so too much $ to replace the valve.) I've installed 3 mini splits, and love the more efficient inverter technology. I've been thinking I could replace my whole system with a Mr Cool Universal for less than a tech would charge to only replace the outside unit in my current system. But even doing that is a bit out of my budget right now. If I can install only this outside compressor, like you did, that will be awesome! I can do this myself relatively easy. ( I would either use the high-pressure quick connects to attach to flare fittings, or just flare the ends of my current lines to attach to the outside unit.)
Can the schrader valves be removed from the condenser with a valve core tool? The ports point down and not sure if there is enough room to get the tool up in there when the tool is fully extended. Thanks and great install!
Fun fact: Even in cool mode the system will do an initial flash of refrigerant via one EEV inside the unit. Also, Gree does not recommend using a filter drier or sight glasses. Unless of course you didn't use nitrogen when brazing :)
@@rstephen001 That's because they think you are going to braze. My source is the gree instruction video for the flexx units. If you don't use the precharged linesets, you can just flare. And I recommend you do, because they work better.
You just need to oversize the filter dryer and you'll be fine. I used a filter/dryer rated for up to 6 tons on my 4 ton pioneer unit and there's no issue with flow, even with my 50ft lineset I had to use.
The price looks too good for an inverter system, hell it's even less than the lowest seer budget system quote. it's Gree flexx product with Mrcool badge on it. I might install one of these at my house in the future. Sight glass and filter drier are not recommended, and not needed, it has its own filter. The system modulate and control the load based on temp and pressure, any add-on might affect it but not a big deal imo. How's it holding up?
QUESTION... I have the 5 ton unit recently installed, the sub cool & super heat ramp up and down every few minutes, is this normal? SC 10-18 & SH 3-13🤔
@@brucethomas8890 it's been a while since if hooked up to it. But after running for a good few minutes it should stabilize. What mode you have it set to ( 3modes?)
Do you see any reason why this would not work on a downflow system? The MrCool air handler is upflow or horizontal only and I would like to install the outside unit with my existing counterflow gas furnace. Does your air handler run at a constant speed? Does the MrCool air handler run at a constant speed or does it vary speed with heat load?
I didn't install a Mr Cool airhander. I used my old airhander. But if your existing air handler has a txv and rated for 410a I don't see why it wouldn't work. My airhander has a ecm motor . Soft start but it's at constant speed once up and running
@@michaelmelnichuk1060 How does the outside unit know how fast to run the compressor? Does it try to maintain a certain superheat? Does your installation vary speed according to cooling demand?
Did you top off the refrigerant after install? The superheat looks great but man that subcool looks a little low. I’m willing to bet the controls target a 10 degree superheat...Being a little low would cause you low sc and minor flashing in the sight glass.
I did not have to top off . It's been running great. It flashes at start then full call my liquid at the sight glass after. since it's variable speed and it varies I believe that's why it flashes off. Similar on chillers or anything that really unloads and unloads depending on load . I may be wrong but haven't had issues besides the saturated temps in evap and condenser looks fine
@@michaelmelnichuk1060 I’m not questioning you or your install, I’m just curious as I plan to install one of these as well. I can’t find any information about the line set regarding whether or not the unit is precharged for a certain length. Normally after around 25 feet I’ll add 0.6 ounces per foot of 3/8” liquid line. With it being non communicating, not having a test mode, and having a fixed blower speed, it’s very hard to dial in the refrigerant by pressures alone. I personally would like to see the subcool a tad higher, if I can ever get ahold of technical support (I’ve been trying for 4 days) I will let you know.
@@brandont9015 I installed a 3 ton about 7 months ago with a custom line set and it’s been running great since! I did charge it according to the manual as my line set was 50 ft.
How is it working? What air handler did you pair it with? A 4 ton air handler? I need to replace my heat pump and thinking of doing this same thing but paring it with a C cabinet that will fit my existing downflow system. Curious how your electric bills are and the reliability of the outdoor unit?
They are rebadged Gree Flexx products. As to longevity, well, that's not exactly the right question. The question is, how good does Mr cool back their systems and if you need a board, how expensive are they. At least with someone like Pioneer or senville (midea stuff), the parts are available and reasonably priced. Pricewise though you can't beat them, esp when a Carrier greenspeed would run you over 10k, easy.
@@davidb5952 no issues in heating. I did disconnect the electric heat call from the thermostat and just left if for when it goes Into defrost. Running like a champ. ...yes airhandler was sized for 4 ton
When you add it to the old air handler does it work the same and how is the cost compared to changing out the whole system to make it work better and cost per month
Well if your old air handler is 410a and has txv. It should work the same. If your old air handler is r22 then it's best to replace the whole system. Also keep in mind what tonnage your old air handler is. Not sure cost per month
@@michaelmelnichuk1060 it’s a 2 ton I think it’s for a small town home was it worth it over all do do it I want to change my system so I can connect it to a solar system and be able to use less power to run it could that happen with a system like this compared to the old one that has a hard start and by the way thanks for the lessens I appreciate it fully and your time
@@lejend69 for me it was worth it because I don't have gas at my house so this unit allows me to run heat down to -5 at 100 percent capacity without having to use my electric heat. But if you are doing it just for being able to run it off generator. I would look into soft start (microair easystart) for your AC
Just bought this same unit with its air handler waiting for it to ship and then i can install it replacing a old lennox unit that doesnt work below 30 how is it holding up? And how does it size up on the electric bill vs the old unit
Sorry for the late reply. System has been performing great. Energy wise it hard to tell since I added a hot tub. But with the hot tub and new condenser my bill is about the same so that tell me that it's doing pretty good.
@@michaelmelnichuk1060 that so funny i also added a hot tub bill was the same as it was with the old ac unit and i kept it at 2 deg colder and added a old 8 person hot tub
I am planning an install for a Mr Cool 4-5 ton Universal unit and I am curious how much condensation are you getting from the outdoor unit? I am planning on moving the location of the outside compressor unit to an upstairs balcony but I am concerned the condensation might be too great to control and divert off that deck surface? Thanks for any help.
That's am interesting question. Are you talking about when it's running in cooling? Or when it goes into defrost during winter time. Me personally I wouldn't put it on balcony. But if that's you only choice. Install it in a tray with a drain tied to it. If you line set is insulated well you should be OK. But in winter time when it goes into defrost you may have a lot more water
The condenser unit comes with a drainage connector that goes to the bottom of the unit. You can hook up a hose to it to divert any water from the condenser unit.
It's been running Ike a champ. No issues. I did have to slow down the supply fan speed to help with humidity. I had to much air going thru the airhandler anyways..
My old 4 ton unit had 30amp so I left the 30amp breaker since I left it a 4 ton. If I would set it to 5 ton I would of upgrade to 40 amp. (Min 35amp and max 45amp is nameplate)
I've been contemplating two 2 ton mrcools to replace my 27yo units. Since i'm just replacing is it something that someone with general mechanical ability could undertake?
If your replacing both the outdoor and indoor units and using the quick connects then you may be fine. Just really pay attention to size of air handler. But if you brazing I recommend using a professional. Good luck
I tried looking up info on exactly how it varies the speed of compressor but it's proprietary and id assume it looking at outside air, discharge temp, suction temp and liquid temp. Also I currently have a ecm motor in my air handler and it works great
@@michaelmelnichuk1060 appreciate the response .trying to see how this setup would work as we have an air handler with 2 damper zones and it is variable speed. The speed on the air handler seems to be driven by the setpoint temperature but the outdoor unit wasn't an inverter compressor, It just had 2 stages.
@@kayzrx8 if it was me I would abandon the y2 at the condenser and leave everything else the way it is since usually the thermostat logic controls the stages. I may be wrong but that's were I would start. Good luck.
I want to do kind of the same thing put a Mr. cool condenser in outside but keep my current air handler inside…Does the inside air handler need to be inverter drive as well or do they even make them like that? I currently have just central air conditioning with natural gas heat my air handler and a coil inside are quite a bit newer than my condenser unit outside which is at least 25 years old and definitely needs to be replaced but my indoor air unit and a coil may not need to be… What types of issues can you have when you want to keep your indoor air handler do the fittings on the air coil match up with the Mr. cool stuff coming in from the condenser or can you just use my already installed cover lines And just hook those to the condenser outside?
@@michaelmelnichuk1060 my current system is r22 so would my old a coil be usable at all? could just the TXV be changed? does mr cool sell just the A coil w/o the full air handler?
@@michaelmelnichuk1060 actually the more research i do i realize i have to find out if my system indeed has a TXV, its older it could have the fixed orifice type or ive also heard "piston" type? is there an easier way to tell other than tearing into the duck work around the a coil? my outside unit is VERY old prob 25+ years the air handler/gas furnace inside looks to be much newer i would say 2-4 years old but that dont necessarily mean the a coil is that new right?
Great video, please do another video or two when cold outside. I really loved the way you let us see it ramp up, and with the amp reading, wow. Will you be able to run in 5 ton at all? I was thinking you should run in 4 ton in summer, but 5 ton in winter if you are able with the inside unit being different.
I'm glad you liked the video. I'm planning on making a video in the winter time to get a comparison video. If I remember I'll try switching it to a 5 ton just to see what it does.
@@paradise1984x keep in mind I can't remember where the pressure sensor goes. It's kinda of a mess how their's works, as it sticks outside the coil with a foam wrapper. Since the mrcool unit can detect how it is working with your setup, it may work fine with a piston, which is what you have now. There are mini splits that have such a setup and work fine. Have fun :) And if you braze, use nitrogen to keep your refrigerant lines clean.
No has to be flared or quick connect at the service valve . It comes with a section of tubing that is already flared and you have to braze to existing tubing.
So what? No other competitor has a compressor that can operate as low as they can. And no, I've looked at their setup and they solve the issue of compression ratios at low temps, while others have not.
@@sprockkets and btw… it depends on the manufacturer how well a system is developed… iphones are also made in china but the company developing them checks the quality. If you buy a cheap system made with imported parts it’s more likely to be a crap system… bosch and fujitsu both manufacture in china but development is in japan for fujitsu and germany for bosch. So think twice before you talk bs and try bringing Carrier to the game.
@@tronixfix lol, now I know for sure you have no clue what you are talking about. 🤣 You think Bosch makes that system? Lol, it's a rebranded comfortmaker series. None of the Japanese brands make anything in Japan, and Daikin has their stuff made in a Midea factory. Let the grownups who actually work in the hvac field do the talking.
@@sprockkets so then shut up…if you can’t even read properly but talk a whole lot about nothing. Go back and play with your AC remote or whatever you do in the HVAC business.
Good job! Cool idea, wouldn't have ever thought to combine the two different system types. That's thinking outside the box.
Thanks bud
Yes, these can be put on any air handler, as long as of course it can handle the capacity. It won't have an official AHRI rating though.

@@kayzrx8 if it was me I would abandon the y2 at the condenser and leave everything else the way it is since usually the thermostat logic controls the stages. I may be wrong but that's were I would start. Good luck.
So if you use only the condenser, what's the seer rating Vs using all Mr cool parts
Not sure. Sounds like a question for Mr cool.
I want to do kind of the same thing put a Mr. cool condenser in outside but keep my current air handler inside…Does the inside air handler need to be inverter drive as well or do they even make them like that? I currently have just central air conditioning with natural gas heat my air handler and a coil inside are quite a bit newer than my condenser unit outside which is at least 25 years old and definitely needs to be replaced but my indoor air unit and a coil may not need to be… What types of issues can you have when you want to keep your indoor air handler do the fittings on the air coil match up with the Mr. cool stuff coming in from the condenser or can you just use my already installed cover lines And just hook those to the condenser outside?
The indoor fan motor can be standard. But your TXV and coil need to be for 410a refrigerant. Not r22. Mr cool condenser is comes with 410a inside
@@michaelmelnichuk1060 my current system is r22 so would my old a coil be usable at all? could just the TXV be changed? does mr cool sell just the A coil w/o the full air handler?
@@brandonoh777 you can change out the txv to a 410a one and it will work . Just make sure you flush your lines.
@@michaelmelnichuk1060 actually the more research i do i realize i have to find out if my system indeed has a TXV, its older it could have the fixed orifice type or ive also heard "piston" type? is there an easier way to tell other than tearing into the duck work around the a coil? my outside unit is VERY old prob 25+ years the air handler/gas furnace inside looks to be much newer i would say 2-4 years old but that dont necessarily mean the a coil is that new right?
@@brandonoh777 it's possible your furnace/air handler was replaced. I would just buy a new evap coil ( case coil ) .
Great video, please do another video or two when cold outside. I really loved the way you let us see it ramp up, and with the amp reading, wow. Will you be able to run in 5 ton at all? I was thinking you should run in 4 ton in summer, but 5 ton in winter if you are able with the inside unit being different.
I'm glad you liked the video. I'm planning on making a video in the winter time to get a comparison video. If I remember I'll try switching it to a 5 ton just to see what it does.
Is the condenser micro-channel? Or copper tube and fin?
Not micro channel
Did you install a new TXV for the indoor unit?
No. Had one in there. Not sure why I would need to Install a new one? Mine was working
Can these condensers be paired with a non-txv evaporator? Hoping to pair the 2-3 ton unit with my Goodman aruf31b14.
You can possibly get away with it, but variable capacity systems really need a TXV. If you have a goodman coil you can buy the TXV for it.
@@sprockkets Thanks for the reply, looks like TX2N is the part# I need.
@@paradise1984x keep in mind I can't remember where the pressure sensor goes. It's kinda of a mess how their's works, as it sticks outside the coil with a foam wrapper.
Since the mrcool unit can detect how it is working with your setup, it may work fine with a piston, which is what you have now. There are mini splits that have such a setup and work fine. Have fun :) And if you braze, use nitrogen to keep your refrigerant lines clean.
Oh and make sure it works for heat pumps. Should be a biflow marking on it.
@@sprockkets thanks for the advice.
Yes tesla ready got a few installed here in NJ
Can you sweat the connection instead of flares?
No has to be flared or quick connect at the service valve . It comes with a section of tubing that is already flared and you have to braze to existing tubing.
How hard was it for you to move it is it super heavy
I put it on moving cart and rolled it slowly. Its on the heavy side for sure!
Where did you buy the condenser unit by itself?
I bought it online. Just search mr cool universal condenser.
Lol, it's a Gree compressor.
So what? No other competitor has a compressor that can operate as low as they can. And no, I've looked at their setup and they solve the issue of compression ratios at low temps, while others have not.
Man your buddy must hate you really badly… a Mr Cool crapunit that’s going to be a pile of rusty junk in 10 years 😂😂😂
As opposed to a Carrier unit that's mostly chinese anyhow? Glad you think you know anything.
@@sprockkets who buys Carrier??.. they crap too… my advise for a new system is a fujitsu or bosch.
@@sprockkets and btw… it depends on the manufacturer how well a system is developed… iphones are also made in china but the company developing them checks the quality. If you buy a cheap system made with imported parts it’s more likely to be a crap system… bosch and fujitsu both manufacture in china but development is in japan for fujitsu and germany for bosch. So think twice before you talk bs and try bringing Carrier to the game.
@@tronixfix lol, now I know for sure you have no clue what you are talking about. 🤣 You think Bosch makes that system? Lol, it's a rebranded comfortmaker series. None of the Japanese brands make anything in Japan, and Daikin has their stuff made in a Midea factory.
Let the grownups who actually work in the hvac field do the talking.
@@sprockkets so then shut up…if you can’t even read properly but talk a whole lot about nothing. Go back and play with your AC remote or whatever you do in the HVAC business.
