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.
