HVAC system (we're in Houston, it's still hot here) stopped working Tuesday. A/C guy came out, determined it was tripping breaker. Would trip immediately after resetting, but after a couple of resets would stay on for a few hours. Suggested we replace breaker.
I replaced the breaker. Same problem. A/C guy some back, swears that everything is good on the A/C side. Capacitors look good. Now it trips every time and won't stay on at all.
Electrician comes out. Examines breaker and panel, says it looks OK. Replaces line from panel to A/C just in case. Still trips every time. Electrician swears it must be a problem on the A/C side.
A/C guy refuses to come out a third time.
I disconnect the fan in the A/C - breaker still trips. Then I disconnected the leads to the compressor - now the fan will come on. So it seems like the compressor, or something in that chain, is causing the issue.
We have a different A/C guy coming tomorrow to look at it. I have a feeling they are going to say we need to replace it. I'm not sure how old the unit is - probably 10+ years, which seems too soon to replace to me. But that might be the best solution.
However, I want to be sure that we aren't doing this prematurely. What else can I check, or ask the A/C guy to check, that might be a cheaper/easier fix than replacing the entire system?
FWIW, we have an upstairs and downstairs unit. The busted one is downstairs. The slightly smaller upstairs unit is OK.
