Hi All: Last week here in Denver, my house experienced two brownouts of about one second each within about ten seconds of each other. I didn't think much of it until a few hours later when I realized that it was getting hot in the house. I checked the supply air and, gulp, it wasn't cool. Ran downstairs and the temp on the thermostat was 80 and the fan was running. Went outside and the fan on the compressor wasn't spinning and it was making a screeching noise.
Ran back inside and turned off the A/C. Ran back outside and turned the breaker off.
Had a tech come out yesterday, and he reported that the compressor wiring was shorting to ground and would need to be replaced.
So, my questions:
1) Can a brownout cause this damage, or did it just happen to fail at that exact time?
2) He gave me an estimate to replace the compressor, which gave me sticker shock. I see that pricing is not to be discussed here, but I'd really like to know what the ballpark should be.
