A heat pump can only pull so much heat from the cold air outside as the temp drops.. So when it gets colder like below 32, it not going to give alot of heat.


The stat you may have is 2 stage. So when the temp starts to drop where the heat pump can't keep up anymore, it will turn on the Aux heat. Aux heat will only run when the 2nd stage is called for.

On some unit, there is outdoor sensor that messure the out door temp.. When the temp drops below this set point, it'll turn off the heat pump and the aux heat starts off.

You dont say where you are or how cold is it there now. For this time of the year and winter just starting . Id say just off hand sounds like the heat pump is to small for the home Also is this new are a old heat pump? Is the coil and air filter clean? Is the big copper line going to the coil inside hot. Has it been serviced of late is the freon up to charge. You see you have a lot of things to look at here to say if its right are not working like it should. come on back here in the same post if we can help you more.
