I have a rheem heatpump I was told that my compressor was bad, but when I talked to a person who works for a hvac company he said most likely my reversing valve was stuck, this past summer the ac went down, that's when I had it checked, now that it's getting cold, if the compressor is bad will there be heat. I was told that I should have heat, but I don't. Can anyone help me find out what the problem is.
You'll have heat if your system has electric aux heat installed or a furnace for backup.
It will be very expensive heat if the former.
Best to get this unit fixed before you need heat.
A compressor is bad if it won't start, is shorted to ground or runs but doesn't pump.
A bad reversing valve or metering device can easily be misdiagnosed as a bad compressor. Get this unit checked by someone who's competent; that may be hard to find.
