The house we recently bought (southern Indiana) has a Payne heat pump.
This winter, out electric bil has been higher than I would expect with a heat pump. I've been paying some attention to the heatpump. At times it runs fine. Other times, it will seem to be running fine. The fan will stop and the unit makes a loud humming sound.
I have come to the conclusion that I need to have this looked at. I need to replace the entire system. The inside unit is a GE with a date code of 138 ot T38. Someone told me they thought it was made in 1971.
I am looking for an idea of what may be going on before a technician looks at it. Would it be best to have this problem addressed or hold out until I can replace the system?
