According to the U.S. Department of Energy, regular maintenance is the key to an efficient heating system. Dirty filters, blocked registers, and improper settings can drastically reduce furnace or heat pump efficiency. Properly maintaining your heating system—whether it’s a conventional system or a high-efficiency one—is the best way to ensure years of problem-free and economical heating. Have your furnace or heat pump inspected annually by a qualified service technician, and replace or clean filters on a monthly basis. Keep the outdoor portion of a heat pump free of snow, leaves, and debris. And be sure all supply vents are unobstructed.
Most heating systems operate reliably for a long time if they are well-maintained. Before you call a HVAC technician for a repair or roll up your sleeves to do the work yourself, call your utility company or check its website—in many areas, the utility company will send a technician to your home to check minor heat pump or furnace problems for free.
