Hello!
I am confused about what to do next, so I am writing to ask for advice.
I have a five or six year old Coleman HVAC system. I bought this five year old new construction house three years ago. I imagine the developers took the cheapest bid and bought the cheapest unit when installing my HVAC. I'd be happy to provide the HVAC model numbers if that would help anyone answer my questions.
In any case my system appears to slowly leak freon R22 from somewhere. The Condenser is on my roof deck, and the HVAC is five floors down in my basement and there is a small and a large line set connecting them. I have had the same tech come back twice in two years, and he can not find the leak by looking for oil spots and using soapy water. Last year they recharged my freon, they could do that again but it is very expensive and prices of freon are going up.
He wants to do a pressure test with nitrogen, but that is also expensive, and he thinks the leak is probably in the larger line set since he thinks it would have had to have been cut somewhere. But since it is a a very slow leak he says it is possible that the pressure test will not show anything. He says my R22 is at half the level that it should be at since he refilled it last year.
So I guess that my options are to (1) do the pressure test and make repairs? or (2) replace the coils in the basement and the condenser on the roof and install a new line set that runs on the outside of my house? or (3) replace the whole system? Or (4) not sure what?
I talked to a guy who says that my third floor gets poor circulation because I don't have a fan with a variable speed. Would a variable speed fan give my system better circulation?
Any advice or input would be greatly appreciated. I am quite confused about what to do. Thanks!
