A refrigerant detector and bubble leak detector (soapy water type solution) will show the leak It’s just time, and 2 days spent making $8k off you while installing a new system trumps 1 day finding a leak, fixing and charging the system back to capacity for $1k They don’t want to do it. No, your unit should not leak any refrigerant It’s a sealed system, any refrigerant loss indicates a leak Leaks are expensive but there is always a repair option
Regular maintenance is always recommended. Freon can be captured and reused in the compressor side if the leak is on the blower side, mine was on the compressor so the freon was purged and replaced cost was around $1300 for the repair $200 for the sweat weld, $1100 for the freon (this was the height of covid when prices on freon exploded and this is a big system used like 13 lbs of freon). Ac repair man said finding a refrigerant leak is like finding a needle in a haystack and i should replace the whole thing It’s 104 degrees in australia and my ac unit has weak airflow that’s not that cold and keeps shutting off after running it for a while A repairman tested the pressure and it was quite low.
Hey so the ac in my car stopped blowing cold air this summer I took it to the dealer and they couldn’t find a leak, but they recharged the refrigerant A few months later, same problem So there’s obviously a leak I just took my car back to the dealer, and they recharged the refrigerant again. Introducing solutions which are not refrigerant or compressor oil into the system will result in system issues, including compressor failure
I have seen more restricted condenser coils cause compressor failure because of stop leak than i have seen successful leak repairs from stop leak. If someone says that you're low on refrigerant and offers to charge it for you (something that most home warranties don't cover), but they don't conduct a leak check, they're taking your money without solving the problem If you're low on refrigerant, where did it go Refrigerant facilitates the transfer of heat. My current home's ac hasn't needed any service like this, so it is all new to me Also, i have pets and toddlers, so a refrigerant leak hidden somewhere is a big concern to me for health reasons in addition to the potential cost of repair
Had the leak check an 18 year old 2 ton r22 heat pump that was hanging in a space the other day Told the owner he should change the unit due to the labour costs and potentially something else going on the unit, he's changed others at this building before for similar reasons, but he decided to go with the repair for this one Disconnected the unit, lowered it down and leaked check around the. If you’re having trouble seeing a leak, use your phone and a black (uv) light to check problem areas, a camera does a better job of showing the luminescent freon than the naked eye.
