breaker tripping on AC. Why??
Our ~15 yr old compressor unit for no apparent reason, tripped the breaker a month ago. Last night, it did it again. In the 8 years we have been here, this is the first times it has done so.
Is this a warning of something degrading in the compressor? Or could it be a degrading breaker instead? I was wondering if anyone had noticed a similar pattern and what it meant. I realize the AC unit may well be near the end of its run but wouldn't want to replace it until I was sure. At which time I probably would swap out the original furnace (20 yr) as well for a high efficiency unit all around.
