Compressor hot to touch?
I've been suspecting issues with the heat pump in our new home. Today was a mild day and the unit did not need to run at all throughout the day. I opened the unit to clean out some leaves and noticed the compressor was hot to touch. On occasion the unit has tripped the breaker in the breaker box. Is it normal for the compressor to be hot to touch even when it has not been running? If not, and I cant imagine why it would be, what could cause this. The unit is a Trane BWD730A100B1.
