Sales are growing so quickly that some installers wonder whether heat pumps could even wipe out the demand for new air conditioners in a few years and put a significant dent in the number of natural gas furnaces.

A friend of mine just had a new heat pump/furnace combo installed. It has a single controller for the whole system (is my understanding), so the heat pump will run normally and the furnace will kick in if needed. I can't recall the details of when exactly the furnace kicks in.

That is how mine works. You can also get a rig that will slightly heat the air inside the heat pump to let it operate at much lower temperatures than normal. Supposedly more efficient than using the furnace.

This is the option we need!
