Yes. Modern cold-climate heat pumps heat effectively in Utah winters, including temperatures well below freezing. Their output drops as it gets colder, so most Wasatch Front installations pair the heat pump with a gas furnace for the coldest nights. That setup is called dual fuel, and it is usually the best fit here.
How a heat pump heats
A heat pump moves heat instead of making it. In winter it pulls heat from outdoor air and moves it inside. There is usable heat in outdoor air even when it is very cold, and cold-climate models are built to capture it.
All-electric or dual fuel
An all-electric system uses the heat pump with electric backup. A dual-fuel system uses the heat pump in mild and cool weather and switches to a gas furnace in deep cold. Because natural gas is relatively inexpensive in Utah, dual fuel usually gives the lowest operating cost and the most comfort.
Will it save money
Compared with a new air conditioner and furnace, a heat pump cools for about the same cost. Heating savings against gas are modest. Savings are larger if you have solar, or if you currently heat with propane or electric resistance, which is more common in parts of Summit County.
Mountain homes
In Park City and the Kamas Valley, winters are colder and longer. Heat pumps still work, but backup heat and correct sizing are more important.
Frequently asked questions
At what temperature does a heat pump stop working?
It does not suddenly stop. Output and efficiency decline gradually as it gets colder. Cold-climate models are rated to keep heating well below zero Fahrenheit.
Do heat pumps help air quality?
A heat pump burns nothing at your home, so it adds no combustion emissions to the valley during inversions.
Does a heat pump replace my air conditioner?
Yes. It is your air conditioner in summer and your primary heater for much of the winter.
