So nice to see a tech that knows how to clear liquid refrigerant out of gauge hoses.
Years ago (I'm old) I would try to teach some of them not to undo high side lines full of liquid!
You're the guy I want working on my stuff.
All the best Bill
Great job! Can tell you take great pride in your work. Thanks for making these videos!
Good job. We've been using Stay Brite 8 for over 30 years.
Without question Stay-Brite #8. Even if it's now 80 bucks a roll it's still great.
Looking good. Been working on a house myself and the plan is to put in a few mini splits as soon as I can. When we got the place there was no central heat, just a couple natural gas wall units in a couple rooms and window air's for cooling so switching to mini splits will be a huge upgrade. Been planning to DIY it all along but the more video's I see you do the better I think I will do. Have a gauge set I inherited from a guy who was doing maintenance at some apartments but have to get a vacuum pump and such when I get started doing the installs and will likely end up helping a few others around town at some point in time once they learn I can actually do that kind of stuff.
Had to LOL about the loud noise when you vented the nitrogen though. That's got NOTHING on my 3000 plus PSI cylinders being dumped to drop the pressure down around 500 PSI, my cylinders literally SCREAM and turn heads for a block when I take them out in my front yard to vent.
A big thank you ! You have single handedly wiped out the entire hvac business community for the entire country with all your free advice. I need a job now, I have been an hvac business owner for 22 years. Not any more. Are u hiring ? I need a job. 😂. I do enjoy your videos ! Luckily people are becoming more and more lazy. So fortunately I am not to concerned. Where is my cell phone ? I can't survive without it. I found it, it was in my hand.
keep up the good video's !
Very nice job. Nice solder work. Very instructional.
20 years in the HVAC industry. We call that a Chop & Swap. It doesn’t cost much more to go ahead and do it right by also installing a matched indoor coil so the txv is designed to operate with the condenser and now the whole system has a ten-year parts warranty. By doing it this way when the indoor coil starts leaking in a few years the customer will have to replace both the original indoor coil along with a replacement of this new condenser because the 410-A refrigerant will be phased out. As in most things in life, the cheapest option is not always the best one.
Oh common guy 410a isn't going to be phased out anytime soon like non available... This system can go another 10years before 410a is phased out at the level R22 is then what you stated would be the situation but your reaching with your comment.
Since he was able to locate the leak, why not close the leak by soldering it. Easier and cheaper work.
@@MBihon2000That's what I was thinking
The matched coil is BS , as long as the out door and indoor are the same capacity and the txv is setup for the refrigerant type used , you are gold. Old fart scare tactics
@@Miketime969 Chop & Swap!
Me gusta la forme en que explica el preceso y su interes de que las personas aprendan! Gracias! I like the way you explain the process of operation, and every step of assembling. Appreciated your effort! Thank gentleman!
Take the schraders out AND wrap those service valves with wet rags before putting heat to them!
The Staybrite 8 doesn’t get nearly hot enough to mess with those like brazing, so I’m not included to do a step that isn’t necessary but if you want to then absolutely! Not saying it’s a bad idea, I just know it’s unnecessary. Cheers
good vid sir.. i sure wish all our ac guy are as thorough as u are.
36 years in the business. Most major installation instructions tell the installer to BRAZE using sil-fos or phos-copper alloy and specifically state. DO NOT USE SOFT SOLDER. 5,10,or 15 years down the road they often fail. The original installer just cost the custmer hundreds possibly thousands by not following the instruction manual.
I was a tech, then service manager, some 25+ years ago before, and while going to, college… I agree that 5 or 15 percent brazing alloy is what I always used, and sometimes code also requires a braze (just like plumber are required to braze any copper underground)… However, I looked up that Staybrite 8, which is 6 percent silver and the rest tin (maybe with some other trace allows, but didn’t lookup the MSDS to verify)… Point is, seems like it works sufficient for line sets, and if allowed by code, I don’t see a problem… I might be worried about using it on a compressor replacement due to more significant vibrations… Although, I can do a braze with acetylene about just as fast, and prefer a sof-flame when in the attic as it is less heat, but higher temp, than the swirl tips like TurboTorch…
He says he doesn't have to flow nitrogen either. I've always used acetylene turbotorch air acetylene. Does MAPP gas not get hot enough to create scale from oxidation?
Wow Kind Sir; you NAILED it right on the head. Of what is going on in the "HVAC companies". And they have been doing it; for untold yrs. Now, I'm an Electronic and AC Instructor for 45 yrs, before I retired.
So I can fix most any electrical or AC's problem; on most all items. And when it comes to HVAC; the MOST fix, is to change the "Start and/or Run capacitor(s)". And it takes LITTLE time to do it. In other words, IF your AC will NOT Run. It is probably that Capacitor.
And believe it or not; on July 24th ago; one of my AC's went out. So I just got on Amazon; and bought the correct Capacitor. Now get this...the price was only $13.77. And IF I was to call ANY HVAC Co; they would've charge, OVER $300.00. Oh yes MOST of them would do it. It's criminal. And they are doing it; all over the nation.
And they can fix it, in less than 30 minutes, usually. How sad. So I am glad you made this video kind Sir. For it NEEDS to be espoused all over the nation. About those horrid criminals!
Actually 300 is not terrible. I’ve heard of companies charging 700-2000 because homeowners have no clue what a capacitor is 🤷🏻♂️ THAT is criminal
A nice neat change over there Dave, good viewing from over here in Oz 👍 Au
Interesting. I’ve always brazed the copper connections, but here you soldered. Great video
Well if you ever read a install manual it tell you absolutely not to solder always braze. This dude never had a fitting blow off but it happens
and pro press is coming nest seen it in food stores on coolers
You should always braze. The only time you soft solder is on water lines
Yep, especially in the future if theirs ever a restriction. That will not hold high head pressure.
See the new stuff at berky plastic coated aluminum lines. Idk how they get installed I got copper for my job
A micro channel coil is easily repaired A compressor that has been open to atmoshere can easily have the contaminated oil removed, refilled and evacuated until dry. For far less than replacing a perfectly good unit. Service first. Sales only when necessary.
Really nice job. I appreciate these videos.
I would rather pay someone like this guy who is willing to show his work than many contractors in my area where they who hide their work even a simple job like changing the filter or spray wash the unit and charging up to $400.00
You mean techs that don’t want you standing over their shoulder asking questions, and maybe giving unsolicited advice? As former tech, I would have no problem explaining the why, but having someone right there would cause a distraction and nobody would want that as distractions cause mistakes… Also, who charges $400 for a filter change or coil wash, why wouldn’t you do that yourself as most hardware stores have foaming cleaners for the evaporator, and all you need is a spray bottle and some chemicals for the condenser coil…
I never allow refrigerant to come in contact with my micron gauge or my vacuum hose. I was surprised when you released the refrigerant with the micron gauge and vacuum hose still attached. Was also surprised that you didn’t remove Schrader cores before soldering. Good job though.
Actually sb8 doesn’t get nearly hot enough to effect the cores or king valve seals, and I’ve had refrigerant come into contact with the micron gauge many times. I clean it with denatured alcohol from time to time.
Thanks man, appreciate you sharing the info
Great job Dave! The Stay Brite 8 is working wonders for our upstairs A/C unit!
👊🏼
No need to flow nitrogen???
I'm not sure about that Stay Brite #8, of course I prefer typical brazing, but overall nothing I can really pick on. The only difference I do is pressure test the system, then install the dryer to limit atmospheric exposure in case you have a leak some where.
I like your honesty 👏👏👏
Watch out for over heating that copper and the even more important the combustible material around it as it enter the house. We make a lot of fires to homes after the AC work was done. That heat conducts further down the line.
Dave. Thanks again for a great video. Even though I do this as a side gig. It does help me a lot to gain experience. Appreciate and God Bless you always!
Bryan do you know what manufacture makes a great dependable mini split systems that a well qualified DIYer could install myself and won’t break the bank? Customer service I see is had to find also. Thanks, 😊
@@Ron_Masterjohn i haven’t installed a mini split system yet. But in the future! There should be a lot. Like Mr cool.
@@Ron_Masterjohn I used alpine home air. My system is 8 years old. Works as good as it did the first day. I diy’d including buying the tools for around $1800. My quotes in 2015 dollars were for $6000. This is for my garage. I used 18k btu mini split.
@@Ron_Masterjohn Daikin is, in my opinion, probably the best for quality… They have commercial systems and I believe created the first variable refrigerant volume (VRV) systems… I have used them, now recommend them as I haven’t been a tech in 25 years, in server rooms / tiny data centers without issue… The problem is, they don’t look as good as some others (last time I checked them out)… Daikin bought Goodman, so the Goodman units might actually be Daikin, not sure, just ask; and might have better looking units.. My number 2 is Panasonic, great quality and slightly better looking, and if the tech does the training, the warranty went from 5-10 years… Both Daikin and Panasonic might be hard to buy if not licensed … These days there lots of manufacturers, most probably just private label of the same Chinese manufacturers (like TCL), which probably are not too bad quality wise if you do it yourself and can replace it yourself if there is a problem as Daikin and Panasonic are almost twice the cost even at wholesale prices…

Right? Get a life already.
You should never solder 410A. POE oil acts as a solvent and picks up the soldering flux and redistributes it throughout the system. This ends up clogging orifices and capillary tubes. There is a reason why every single manufacturer's instructions say "braze".
Such dumb scare tactics
@@Miketime969 You are clueless.
@@chaseme9860 your making assumptions that huge amounts of acidic flux are being used and making it inside the piping . Not clueless but thousands of jobs in the field done with solder and not a single solder joint failure in 24 years
@@chaseme9860 go babble around and repeat more nonsense
@@Miketime969 This has nothing to do with joint failures. And yes, you are clueless if you believe what you say. A cap tube can be as small as 0.5mm. A pin drop of flux will clog it. Also, flux contains water. POE oil is hydroscopic, which means it wants to adsorb water. Water is a non-condensable. This is very bad for the system. I encourage you to contact any manufacturer's engineers and discuss this, but if proper HVAC standards are "babble" to you, you probably can't be helped.
Why are we replace a whole condenser unit for a little hole? When the hole can be patched up, replace filter dryer and compressor oil.
They also make braze free connectors called HVAC push / quick connect fittings / unions similar to Shark Bite. They're made by Zoomlock, Rectorseal and others.
The problem is, the condensers all have a bell at the end of the copper pipe and once you cut that off, you don’t have quite the clearance you need for those fittings. But I think the hvac push fittings are awesome. Time will tell if they develop leaks. I have one system I used them on and so far so good!
@@diyhvacguy don't let Steve Lav know
Great job. Well done
Hi i’m a DIY person. I may not know all there is to know about HVAC but over the years I’ve learned enough about it to have an understanding and I have a mechanical background as well. I’m not comfortable with the way you installed that system. You seem to like to cut corners to make things easier. You chose a system that’s oversized for the installation and is causing a higher head pressure. My assumption here is it’s going to shorten the life of the unit and slightly increase the operating cost.
The stuff you used to connect the pipes together I’m not up-to-date on yet will withhold my comment. Sounds like it made things easier in a safe way. I am a firm believer in following proper procedure as listed by the manufacturer.
Beyond my comments, good job😇
The Ruuds have a larger footprint, but the tonnage is the same as the old trane system. The head pressure was due to the smaller suction pipe size. They weren’t interested in paying to the pipe it so it is what it is.
I bought one of those gizmos you know the soft start Bluetooth today I’m gonna put that thing on get my AC heater generator ready
Nice install!
Thanks!
very awesome! u have saved people thousands of dollars.

Nice work
Stay-brite 8 is legit! I've done multiple complete system installs with it, zero issues.
Amen brother. The believers are far and few between
Sad for the homeowners of this damage that’s was conducted by this cleaning crew. They should’ve talked to the company owner about some form of liability and compensation for the damage to the coil.
She didn’t know for sure and I’m sure they wouldn’t have owned up to it, or even knew they did it for that matter
Good video! 👍
not sure if the labor cost was worth it but I would have tried to repair the coil with a full report for there insurance then let them go after the landscapers that hit it.
they should have noticed and shut it down so they could pay for the compressor or the entire unit
Find a good AC man that knows how to find and fix the leaks. I did. Save a ton of money!!
I'd like to know how best to choose a condenser to work with my existing air handler and linesets. 15 years old 3 ton unit that was showing signs of weakening even when I bought the house 8 years ago. South AZ but house kept at 90F all summer. It's not a critical item as the house is empty 8 months a year during the hot months. I love the idea of soldering with StayBrite system and I;ve installed my own Minisplit successfully in my northern home, using basic gauges and vacuum pump. Was thinking of something like a Blueridge or Goodman 3ton condenser for $1600-2000. But I do not have knowledge of matching it to my old system - maybe a video on that topic some time?
Always sweat from the lowest point in the fittings... heat travels up and doing it in the manner exhibited introduces the potential that the first joints lose solder to the point of weakening the joint.
Come to Vegas ! Great 👍 work

@@diyhvacguy My buddy lives there, I'll tell him to reach out to you if he has A/C issues. 👍🏻
Thank you for the video. Where do you buy the 3/4" blue hose (for vacuum pump)
Great job, my man. Great job! Keep on pumping!
Shouldn't 410A be upside down because of the mix inside
We've got a unit that's about 5 years old and the return line is partially getting sucked together and causing the unit to freeze up. We have an ac guy that has been out, does it need a bigger return line?
I just had a 2.5 ton Rheem unit installed, looks a lot like that one. It's really noisy though. Is that something to worry about?
Nice job and video. But not sure as a DIYer I would consider doing this repair. I do basic things on my units. Change capacitors, contactors, clean condenser and evaporator coil if needed, flush drain lines.
Well typically there is refrigerant in the system that needs to be recovered. I’m sure you are capable of doing the job- the question just becomes investing in one time use tools vs having someone else do it. $400 for vacuum pump. $800 for recovery machine, 300 for vac lines and gauge, $200 for manifold. Plus miscellaneous I forgot and I thing you would need to spend 2k to do the job before buying the condensing unit. I didn’t even mention refrigerant, and you need 608 certification. I have 2 units from 89. When they go down I’m definitely doing the job myself. Even if it costs me 3k for the above things, where I am living it would cost me 40k to replace both units. 3k for things I could sell is well worth the cost.
@@Samlol23_drrich Those are all good points for DIY to do this type of project. Just curious, what state do you live in ? That’s quite a pricey change out for a residential system.

Excellent vIdeo...may I ask what brand pipe insulation (white) was used in this project?
I could have saved $5-6k installing my own new system last July 2022. The installers seem lazy and overworked in July. The outside guy was vacuuming the system and forgot to open access into the lineset 🤦♂️. He also melted the base pan on the new system during the brazing cos too lazy to cover stuff with a simple wet towel or some heat paste. Amazing how much companies charge these days and do crap work. 14 months later there’s a compressor issue now.
Man, sorry to hear that. Hopefully they make it right.. that’s what I’ve been telling people. Just because it’s a well known company doesn’t mean it’s gonna be good work. Just like buying a brand new truck doesn’t guarantee it’s gonna be any good
@@diyhvacguy compressor is under warranty. But the labor to install it and remove old one is $1485.00. They are covering the $1814 cost of refrigerant. Which costs maybe $200. I think I saw 25 lbs at ability refrigerants for $399.00. It actually went down since last year cost wise 😱. I’d do it myself if I could get the compressor under warranty but I highly doubt the manufacturer will give it to me 😂. 13.2 lbs of R410A.
@@diyhvacguyI bought a DIY MRCOOL 24k mini split I installed myself and it’s been running since May 2019 but this central split system we financed last July 2022 already croaked. From a hvac company in town. Crazy.
Thanks for taking the time to respond!
Great video, however why did you add 410A to a new loaded condenser unit?
You need to get your self a bender and a sewger to have the minimal brazes then it can be a clean install. Not bad though.
Can you tell me where you got the white insulation? I'm trying to find something better than the 1/2 rubber tubes at the home stores.
exelent information
it creeps me out that some installations have thermostat wires just exposed to the elements like that. Our air conditioner installation actually ran them through a conduit. They are rated for in-wall use, not external use. Wind, hail, critters, and even your dog can easily damage those cables if they are not placed inside a conduit.
And why does this creep you out? Haha I’ve literally never seen it in conduit.
@@diyhvacguy Well, it says in my reply that wind, hail, critters, and even dogs can damage those cables. I get why you think it's silly since I'd have to call a guy to fix it every time that happens. Low voltage wires should be in a conduit by code. I don't care if it's low voltage. They used to do it. It looks really stupid having these naked wires flapping around in the wind. It literally is part of your home wiring. Why wouldn't it make sense to protect it?
exposed stat wire is funky but reality is other than a dog or whatev they last many years not running through conduit. I've never seen the brown cover cracked
It is not code - It might be better practice - Everybody thinks they are an expert.
I prefer it when i only have to change a condenser or heat pump, takes 1/4 of the time and still make alot of profit
Hopefully you can respond soon. I'm purchasing a new Bryant 2 ton 14.3 SEER ac. I would like to install a soft start unit on it, Will the ICM 870 16A that you mentioned in one of your videos work for my new ac unit?
After system only blowing warn air , replaced capacitor and I thought it was fully fixed . It was blowing cool air but doesn't get to set temp 78 gets to 81 during verry hot days here in San Antonio Tx with 110 F heat index . I've replaced filter even though it wasn'r filthy clogged . Just washed wuth hose the outside unit coils from the outside and noticed the fan changed from very warm aire to cool , But didn't make a difference still 30 minutes later hasn't gotten temp lower . Still at 81 . What can a DIY try next ? No frozen lines . Not long ago a couple months ago it was getting down to 74-76 degrees
Not sure if this a myth? My plumber states after soldering the copper pipe he grabs a rag and wipes down the joint of the flux lead connection. He claims you will not see really dark green tarnish in several years.
Hi Thank you for all the video's. My grandkids were asking about the staybright their foreman was saying to only braze with nitrogen as that's the only way. Do you have pipe cut aways that show what it looks like inside after using staybright 8?
I have a video where I compare the two and cut both of them in half. Check it out 👍🏼 just scroll through my video library and you’ll find it
Nice work. Does vacuuming from only one side still do the same thing in the end.
Yes, and you are verifying that the whole system gets a good vacuum in that you have the micron gauge reading on the complete opposite side of your vacuum pump 👍🏼
hello Sir I have a problem with blowing my 3a fuse of split unit. I have had HCAV company out 6 times and also a electrician in the past 7 weeks. I know they come out and replace the 3a fuse however not sure if they have checked the contact coil the refrigerant or even the condensate drain. How can I hold them accountable for these checks. I don't want trouble just want the ac fixed. The fuse blows sometimes same day and in the past 7 weeks I have replaced it 6 times. The longest it has run is 4 days without blowing the fuse. I have seen the refrigerant gauge on them once when they have come back in after looking at the ac unit outside. also the condensate drain used to be damp outside and now it is bone dry where usually it is a little puddle. please advise if you can?
Awesome Dave!! You went and looked at it, and installed it in 1 day? Or you had to come back the next day to install condencer?
The day I went happened to be July 4 so I had to come back a couple days later.
Hey Im sure you've heard about this and I know you don't do Automotive A/C but I figured I would ask anyway... R152a, I've seen videos and read in forums where people use R152a as a refrigerant in automotive A/C systems. And when I say R152a Im mean Dust-Off Duster compressed canned air. R152a is difluoroethane and Dust-Off Duster shows CAS number 75-37-6 which is R152a. If I were to start fresh with a vacuumed system and added this to my automotive A/C system In your option would this technically work? Thanks! Great video as alway!!
I don't think it's as much the complexity in the swap out as it is the potential electrical danger with the fact that capacitors hold charge.
I didn't see if that condenser is bolted to the slab. Is that required?
At the 7:20 mark. You soldered the line set. I thought you have to braze the line set connections. Please explain. Thank you
Need to protect the thermostat wires. Piece of flexible conduit works great.
i use sealtight, other than dog protection, 've never seen the sun crack the outer coating in my 30yrs of hvac work
@@ltcuaa Yeah, it's the critters and random falling branches and the like. The little wires make me nervous. Mine has small die metal flex conduit.
I’ve watch a few of your vids, great content, but I do wonder why you have to remove the schrader valve before pulling the vacuum?
It greatly restricts flow so everything takes a lot longer.
Yes it takes 10 minutes for me to pull a vacuum whereas if I had the core in, it could take an hour. If you have a plug in vacuum pump and you can let it run for several hours, you can totally leave the cores in 👍🏼
My old system had two compressors, a high and a low. The one compressor went out and they replaced the whole system inside and out. Something tells me that all they really needed to do was replaced the outside component.
It just depends if the system is a r22 System then when you change it you have to change everything because they do not make R 22 systems anymore. I’ve actually seen some people replace the R 22 expansion valve with a 410 expansion valve at the evaporator coil and then just change the outside unit with a 14 condenser. Only thing is that now you’re mixing two types of refrigerant oil which is a big no-no.
@@georgehuerta1990Well that makes sense. And I hear they're changing to a new type of refrigerant now. I expect that'll probably be the same thing all over again.
@@Leonardokite yeah I’ve heard that too they’re talking about getting rid of 410 to go to some other goofy refrigerant all you really have to do is follow the money trail it’s got something to do with money. I’m sure somebody’s Patten on the refrigerant has run out and now they come up with something else. So now they’ll start telling customers well now you have to change all your equipment because of the new refrigerant blah blah blah.
Can you review the MRCARTOOL L302 Digital Refrigeration Manifold Gauge?
When do you braze vs solder with stay Brite 8
I changed the capacitor and it is not blowing cold air. Help Freon R22. air conditioner. The guy came out and said it was low. He put more in and still no air. Now what? Thank you for sharing this video.
I don't understand the logic for not adding more refrigerant. You're pressures were high because it was 91° outside. System was low, needed to get that subcooling up above 7, dipping down to 5 is no bueno. VSat was probably high because it was hot in the house. TXV was doing it job keeping that Superheat pegged at 10. Just because it's a small system on a well insulated house does't mean you should be lazy and and not dial it in.
I was worried the high side pressures were going to be too high. I appreciate your insight on this though!! In your opinion that high side pressure was ok? I felt like on a 100 degree day it would be mega high.
@@diyhvacguy For air temps in the low to mid 90°s pressures were what you would expect for 410a. Adding more refrigerant would not have resulted in a significantly higher pressure. The pressure is a direct correlation to temperature. When increasing your subcooling all you're doing is stacking more liquid into the condenser. At a certain point, your head pressure would increase because the surface area of the coil would be effectively be reduced because of the amount of condensed refrigerant but this would be beyond your target subcooling of 9-14. At 100° on that unit I would expect pressures anywhere from 410 to 430.

how do you clean your manifold gauges?
3:34 that switch with the button, what would cause that to pop out even when the handler is calling for air? My outside unit keeps turning off and the button if i push it in will let the outside work but as soon as i let it go it turns off. If i reset everything at the breaker for 15 minutes it will fix it for a little while.
I believe you are talking about the contactor. If it is calling for cooling and the contactor is not pulling in, you most likely have a safety (high pressure possibly) interrupting the circuit. Possibly the thermostat is not sending a call for cooling(low voltage signal to the contactor). You would need to use a meter to find the break in the electrical circuit to start with. My information/knowledge is limited, hope this might help.
Avoid any system that uses micro channel tubing they appear to have a much higher failure rate

I would recommend Daikin because of there warranty. We have been selling them for the past four years and have very little trouble out of them, what trouble we do have is usually user error or installation error. There inverter technology is well thought out.
Customer support is very helpful if you have questions or problems.
@@nd3498 thank you and will check the Daikin tomorrow out. So if you do have any issues their customer service is easy to get ahold of and they will help customers out? I see so many don’t even get back with buyers.
Are you able to get authentic MAPP gas and not the new MAPP like gas that they sell in the big box stores like HD or Lowes ? Where in your description box find the link ?
Great job Dave, l need an advice on my central ac at the start of this summer when turned it on with thermostat set at 62'° it was cooling but air flow was minimal and when l checked the condenser outside the whole pipes were ice frozen l thought it was the capacitor bought a new one and replaced it and it's still the same pipes still frozen and the room is not going any lower than 82°?
Dirty filter or evaporator coil will cause this. Or it could be low on charge. If you need help diagnosing, check out our remote assistance page at Patreon.com/diyhvacguy Hope we can further assist you! Cheers
Alright thanks l will check it out.
It's frozen up put it on fan only call a contractor to put freon in it and hopefully find and fix the leak
Definitely check the filter and the coils before the freon level is checked
Alright thanks
At 4:00 you don't know why whoever sweated the copper pipe did it so far out, well at about 4:39 I guess you know why the person who did it before came out so far, lol! IMHO it looked better without a bent pipe, the way it was.
0:24 careful with your gauge hook, they can damage the fins on the coil..
Is there a way just fix that condenser hole instead of replacing whole system ?
Any reason why you're not putting the dryer inside the house?
Is there a reason to use solder or braze?
I'm retired.....but in my area, most people are old fashion, and would not use your "Jobber" app........I understand it may make it easier on you. But when I have to go online for something....I go to another service company where I can talk to a human. Not everyone has a computer or the "want" to use it!!! And I am an old service guy too, and would never subject my customers to some stupid app....I know....go with the times....But in todays world where there is no person to person contact....all we have is the personal service that really counts.....
Great work as usual 👍
Wow I never knew if you get a hole in your condenser you have to replace the whole unit.... I was thinking you could patch it or something....:) God Bless....
You are not..he is not a real tech..more like a sales tech..the type of tech you don't want near your house.. SALES SALES SALES..LOCK YOUR DOOR AND HIDE....that unit is only probably 1year old lol what a shame
@@lopapao Hahaha for real. I love that the title is "What HVAC contractors don't want you to know". Yet he is fucking robbing someone.
Got to love your installs 😊
Did you isolate your micron-gauge from potential oil contamination before you opened the service valves? I like to see a ball valve in-line (another valve core removal tool works great) to isolate the gauge before releasing the gas.
He had a valve on the micron gauge, but forgot to close it before opening the service valves. Micron gauge is now junk.
Nah, clean it with denatured alcohol per the owners manual and it’s good to go. Mine has seen refrigerant and it’s not dead after that by any means.
What type of insulation do you put on outside piping going from fan/condenser to house?
It comes with the new line sets from the supply house. I don’t think you can get it separately unfortunately
So you don’t have to replace the entire unit because of the new refrigerants?
I have a question having about a 20 year old Armstrong 1.5 ton unit that is maybe a good candidate for repplacement soon. It is about 10 SEER and wondering if I can replace it with a 16 to 17 SEER single stage with soft start. Is that possible and what is good source to purchase one?
Most likely need to upgrade your evap coil to be compatible with the higher seer condenser, which may also mean upgrading your furnace as well to handle a bigger sized cabinet required for the evap.
@@turnedearthdesign8678 Well this unit is for cooling only AC. I to sounds like replacing it with mini split is maybe more cost effective as I can use the electric line in place just change the breakers
Also depends on the refrigerant line size. If it goes up from 3/4” to 7/8” line size then your efficiency will all go down the drain.
Just curious You can’t repair the hole in the condenser coil by brazing / Soldering it ❓
My guess is “no.” I had the same question for another tech and was told those holes can’t be repaired…
