The name heat pump is somewhat of a misnomer. It gives the impression that a heat pump can only provide a source of heat for your home, but the truth is that it can also cool your home. Heat pumps run on electricity rather than fossil fuels and can work independently of a traditional HVAC system. In the right climate a heat pump can even take the place of an HVAC system. Conversely, a furnace system cannot provide cool air while an air conditioner cannot provide heat. A heat pump might be an excellent solution to provide heating in Nashville, TN, without the need for an entire HVAC system overhaul.
