Due to roughly 6" of snow and continued freezing rain today, the condenser housing louvers are freezing up on the sides. I have removed snow from the top and away from the bottom of the condenser. The heat pump condenser coil does routinely go into defrost and melts any ice off the coils. My concern is the possible airflow resistance over the condenser housing air louvers. Can I take a hair dryer to melt the ice off the housing with out doing damage to the condenser?
