heat pump freezing up

(OP)
After replacing the compressor, my heat pump freezes up, at night, about a week after recharging.

RE: heat pump freezing up

I'm sorry to hear that... but are there any more details? Any bubbling in the sight glass? Is the new compressor the same model as the old compressor? It's the evaporator that's freezing up, right? Why did you replace the old compressor? Did they recharge with the right kind of refrigerant?
