Heat Pump

Temp is 36 degrees outside--noticed that the heat pump outside and fan inside continued to run much longer than usual, with cool, rather than warm air coming from the vents. Found ice on the outside coils and shut everything down to thaw. System seems to be operating normally, once again.
Is this typical of heat pumps or do I have a problem?
This is a Rheem 4 ton unit--5yrs old--"scroll inside"

Hi: Soapboxbj

I do not profess to be an expert on heat pumps. I deal strickly with natural gas appliances.

What I can tell you is that a heat pump draws the heat from the outside air and brings it inside. The lower the outside air temperature is, the less heat it contains. Therefore, the less heat there is to warm the house. This alone will make the unit run longer to raise the inside temperature.

Regarding the icing up of the lines, it may be do to a low freon charge.

I suggest you ask this question in the heating and cooling forum. You will get a professionials opinion to your question in the heating and cooling forum.
