I think something is wrong with my heat pump. I went outside to the heat pump and here is what happened:
1. I noticed a cool discharge line and low noise as if only the fan was running.
2. I noticed the compressor was not functioning as it was making no noise and the lines had no obvious sign of refrigerant moving in them.
3. I saw the heat pump begin cycling rapidly.
4. The heat pump has now been on steadily but with immediate frost buildup on liquid line and evaporator coil outside.
I think something is wrong. My heat pump hasn't turned itself off in what seems like forever.
Edit: Just after I posted this I went back outside to make sure nothing wrong was happening. Well, it was making the low noise of the fan only running. After it ran like this for a while, the heat pump turned itself off. The thermostat was STILL calling for heat. At this point, I just turned the thermostat down so the unit wouldn't come on until I can call for service for Monday (I hope). Any thoughts?
I personally think it's because the heat pump is mismatched to a Lennox air handler. I think the charge issue people have talked about when it reverses it's cycle is coming to truth in my case unfortunately.
