Was outside this morning cleaning up and noticed that the heat pump outside has a little bit of frost on the coils. Is this something I should be concerned about? Is it not as effective when it does this?

The weather when I seen it frosted slightly was

22 degree windchill
24 degree dewpoint
83% humidity

Indoor temp
set at 73 degree
actual temp 73
Humidity 36%

Windchill has little to no bearing on a heat pump. Except when its in defrost.

Without knowing the actual temp, can't tell much about whether it should have a lot of frost or not.

30°F at a 15MPH wind is a windchill of 19°F.
