My heat pump runs even when it's under 22 degrees. My furnace won't start when it's supposed to. Last night it was about 5 degrees outside and my themostat was set to 68 degrees and the temperature in the house got down to 55 degrees. I can run the furnace using the "EM Heat" setting on my thermostat.
We got lots of snow which drifted all around the heat pump. I cleared most of that away this morning. Could that have caused the problem? Any other advice on what to do?
