Our AquaCal AeroTemp heat pump model AT 12000 installed in 2002 has stopped heating but the fan is running. My HVAC guy happened to be over servicing my boiler and I asked if he could check out the heater and he spent about 15 minutes testing some things (capacitor and something else). He thought it was probably the compressor and if so we will need a new heater due to the age of this one. While the heater was running we also noticed a draw on our power inside the house which gradually increased to about every 10 minutes so I'm wondering if I should have an electrician look at it (maybe mice chewed on wiring? but then wouldn't the heater not work at all?). Could the bad compressor cause the draw on our power? I'd rather not spend money on an electrician if it's not the electrical, I'd rather put the money towards a new heater. We've had a good run with this heater but I'd like to be certain it's reached the end - any advice?
