Dwight Rittenhouse from Mount Union Lumber & Supply explains what exactly is a heat pump, and the importance of having a technician clean the internal parts of your heat pump once a year. Whether it’s a Fujitsu or an AirTemp heat pump — it requires no gas or oil in the winter, running solely on electricity. Dwight says “this is the cheapest source of heat known to man.” If you’d like more information on heat pumps, call 814-542-2981.
