I've only done one lineset repair. It was when I worked in apt maintenance. We had to cut the ceiling and repair the suction line where it was leaking...fun shit
i found out putting a filter base with at least 2 inch filter,makes a big difference in the performance,nice unit,nice video, i would add a trap also.nice job.
I noticed the original lineset has white insulation on it. Apparently there is a huge issue with new copper and the insulation they are using. Some chemical in the insulation creates an acid when mixed with air and water creating tiny leaks in the linesets. Thinking maybe this was the case here? Did you test the lineset after? Look up "leaky white linesets."
When I do that test I just pressurize to 200psi and THEN close the king valves. It evens it out without you having to pressurize then stop and try and get it equal
The only problem is you never confirmed where the leak was. How are you gonna explain to the customer the reason changing the line set if in a few months you come out and its low on freon again?
The liquid line was leaking between the condenser and air handler. That’s the only isolated “component” that had a pressure drop overnight. We didn’t charge for changing the lineset.
Yes I picked up where you said the liquid line was low the next day. Why no charge to the customer? Especially when they did not want to change the line set originally?
Think you can condemn it faster by using electronic leak detector and digging up chase. Expose both ends and put detector into chase. Just depends on how good of a leak detector you have. Also have to be careful that you don't pick up refrigerant from it being in the insulation from a leaking joint outside of the chase or evaporator coil. But if line set leaks isolate to confirm. Nice fix.
Thank you and yea that works too! There was a ton of cured foam on both ends of this one. I went this route just to avoid cutting all of that up and removing it.
Wish I could count one hand for line set leaks. I need both hands, feet, and others to count how many I seen or heard from other technicians. Lots of new construction and quantity over quality causes many issues.
Yea Ness....from what I’d call “natural causes” like this....I can count on one hand. Now I’ve seen more than I can remember of leaking line sets that were punctured by other trade workers like roofers, sheetrockers, electricians, etc.
We knew the system was leaking, but no signs of oil anywhere. Our electronic leak detectors did not pick up on anything on the air handler or condenser. So, we pressure tested the condenser, lineset and air handler separately. To confirm what component(s) was/were leaking.
Nice job guys. Keep it up! I learned some new tricks to pressurize system for sure. Like fill nitro thru true suction port. Also did it have a burn out or is that like an extra muffler? Lol The thing that's on the suction line
@@AIRMANHVAC gotcha 👌. That's neat. Hey you should go over the components of the system. I'd like to see some. I dont do many inverter/high seer and wouldn't mind seeing more of that. Maybe how to force a defrost. Also some ideas for content. It would be cool if you showed us some Air flow/ducting design Minisplit maintenance Commercial 3 phase Electric heat wiring Gas furnace tune up/troubleshooting I'm sure you plan on all that but I thought I'd throw some ideas.
I feel your pain, great job isolating the leak. A lot of guys don’t realize how time consuming this type of problem can be to find. Great job👍
Thank you....time consuming definitely describes this lol
Thorough job. Those in wall leaks can be pesky

Yea…it was definitely leaking
Why would leave the suction line drier on?
That’s not a drier, it’s a muffler that the manufacturer requires for this unit
If the refrigerant lines are supposed to be insulated, at least one of them, then both of the copper tubes wouldn't rub against each other right?
@@bctopper I believe the 3/8” line rubbed through being in contact with the pvc chase and some “dirt”.
When I do that test I just pressurize to 200psi and THEN close the king valves. It evens it out without you having to pressurize then stop and try and get it equal
Nice info. Thanks

Great test, only next time use a shot of 22 with the N and if its 410a crank that pressure to 500
More videos!
Bro! You work Dothan man? I used to work in Dothan all the time! I live actually 30 minutes out of it. Crazy lol
Hahaha yes we do! Small world

why isolate the condenser when doing a leak check ?
We knew the system was leaking, but no signs of oil anywhere. Our electronic leak detectors did not pick up on anything on the air handler or condenser. So, we pressure tested the condenser, lineset and air handler separately. To confirm what component(s) was/were leaking.
@@AIRMANHVAC thanks
Are you in Texas?
Alabama

The thing that's on the suction line
Great question Caleb. The 20 SEER Bryant & Carrier heat pumps like this one came with a suction line muffler.

Thank you for the content suggestions!
Good job 😜
Thank you
Did I miss something? I don't see nitrogen running while brazing.
🤦🏻♂️🤦🏻♂️🤦🏻♂️
I would have returned the unit
Yea...I was given the option. Homeowner opted for repair on the spot instead of waiting 2-3 days for a replacement condenser. Crappy situation.
Thief. Interesting how you claimed there was a 50 psi drop but didn’t bother to show it on camera.
