Air source heat pump - winter icing

Piwoslaw · 11-26-10, 01:34 PM

My Mom has an ASHP at her house in NC and recently complained that she has to turn it off when it rains during heating season because of icing. Is this normal?

We once thought about an awning of some sort, both to keep the rain off in the winter and for shade in the summer (it's on the west side of the house, so gets a lot of sun in the afternoon). But then rain on the coils is good as long as it doesn't freeze, right?

Any help, please?
