However, freezing incidents can occur when the tem-. perature remains above 20 degrees F. Pipes exposed to cold air. (especially flowing air, as on a windy day) because of cracks in. an outside wall or lack of insulation are vulnerable to freezing. at temperatures above the threshold. However, the 20 degrees.
When the outdoor temperature reaches that 30 degree range heat pump start to frost up. Water vapor in the air condenses on the cold coil fins and then freezes. When the frost builds up to the point that it affects the performance of the heat pump, the heat pump is supposed to go into a defrost cycle. The reason I asked if you had a gas or oil furnace is that some contractors will switch off the heat pump at between 30 and 35 degrees to avoid the defrost cycles.
