Will a ductless heat pump increase my electric bill?

Unless you use electric resistance heat for your home or business, a ductless heat pump will increase your electric bill. However, if your current heating system runs on oil or propane, the savings from burning less oil or propane will exceed the increased cost of electricity. When a ductless heat pump is used for cooling instead of a window air conditioner, it will decrease your electric bill. In addition, a high-efficiency model that qualifies for Efficiency Maine rebates will cost less to operate than standard efficiency ductless heat pumps.
