21 year old Carrier heat pump was heating at 125* I set the thermostat to 62* and it ran for an hour (inside temp was 55*) I’m sure that was from auxiliary heat but, the compressor fan was blowing (had a reversing valve). I lowered the temp to stop unit from heating and waited 10 minutes. I then raised the thermostat 1* and the unit cycled on and continued to heat at 125*. The suction lines were at around 100* (big line) small line was at 80*. Should I be concerned ? Usually the auxiliary heat will run until it supplements the temperature and the compressor will kick on and heat a much lower temp. somewhere around 100* .
