Hi, I'm new to this site. Can't get any straight answers from my contractor, so I thought I would give this a try. Appreciate if anyone can provide some advice what is going on with my heat pump.
Situation: I have a 3-ton ground-source heat pump which I use for heating and cooling. The unit is about 2 years old. The unit is in my basement, when I run it continually the compressor will shut off every 3 hours or so for about 30 minutes or so, then it will restart on its own. Then it runs fine for another 3 hours or so, then shut off again for another 30 mins. This has been going on since I bought the unit. I am trying to figure out if this is normal. I thought that compressors could run continuously.
More info: the unit has water circulating from a well to do the heat exchange with the freon. The thermostat turns on an actuator on the unit which allows water to circulate, the actuator in turn sends a signal to turn on the compressor. During the 30 mins while the compressor shuts off, the well water continues to circulate. So the thermostat and actuator seem fine. Hope this is clear, I am not an expert on this.
My contractor advises that compressor shutting down is normal, that it needs to "cool down". Somehow does not sound right. Does anyone know if this is normal or what the problem may be?
Thanks in advance!
