At that point most heat pumps will turn on costly electric heat strips but a dual fuel heating and cooling system utilizes an efficient natural gas furnace saving you from high electrical bills in the winter.
Electric heat pump with gas furnace.
A heat pump condenses heat present in the outside air usually down to about 30 degrees fahrenheit depending on the region and the amount of moisture in the air and pumps it into the home.
The gas furnace would be the secondary heat source instead of using the heat pump s electric heat strip when the temperatures drop.
Compare costs efficiency installation operating costs and more for electric heat pumps vs gas heating to determine which hvac system is best for your home.
Electric furnaces convert nearly all of their energy into heat while gas furnaces can vary.

In heating mode heat pumps are essentially an air conditioner running in reverse.
Homeadvisor s complete heat pump or forced air furnace guide defines the differences between electric and gas heat pumps and gas electric propane and oil furnaces.
When the temperature drops below freezing there s not enough heat in the air to sufficiently heat the home with the pump alone so the backup electric or gas furnace kicks in to provide warmth.
