A heat pump on top of a gas furnace
This Maple Valley home already heated with a Trane gas furnace in the garage. The owners wanted to pay less for gas, so instead of replacing anything we added a 3 ton (36,000 BTU) Bosch heat pump to the system.
The furnace stayed where it was. The heat pump outside and the coil above the furnace now share the same ductwork, and together they make a dual fuel system: two sources of heat, one set of ducts.
The install took two working days.
