Should you really have a yearly furnace tune-up?

In a word, yes.

Proper maintenance of your heating system performed by a qualified heating, ventilating, and air-conditioning (HVAC) contractor is one of the most important steps you can take to prevent future problems, according to Energy Star, a U.S. Environmental Protection Agency program that helps businesses and individuals save money and protect our climate through superior energy efficiency. Dirt and neglect are the top causes of heating and cooling system inefficiency and failure.


A cleaned, lubricated, and properly adjusted furnace runs more efficiently and uses less energy, and regular maintenance and inspections can help prevent more costly repairs later on. Furnace manufacturers typically include language in their product warranties requiring proper maintenance to ensure coverage. Most importantly, an improperly working system could be a safety hazard. Energy Star recommends having a qualified HVAC technician come in and do at least the following:

  • Check all gas (or oil) connections, gas pressure, burner combustion, and heat exchanger. Improperly operating gas (or oil) connections are a fire hazard and can contribute to health problems. A dirty burner or cracked heat exchanger causes improper burner operation. Either can cause the equipment to operate less safely and efficiently.
  • Tighten all electrical connections and measure voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components. Lubricate all moving parts. Parts that lack lubrication cause friction in motors and increase the amount of electricity you use.
  • Check controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly.
  • Check thermostat settings to ensure the system keeps you comfortable when you are home and saves energy while you are away.

Maintenance you can do yourself includes inspecting, cleaning, or changing air filters once a month in your furnace and/or heat pump. Your HVAC contractor can show you how to do this. A dirty filter can increase energy costs and damage your equipment, leading to early failure.

Ask neighbors, friends, and family for HVAC contractor recommendations. Check the contractor’s license before you hire at HVAC contractors get busy once summer and winter come, so it’s best to check the heating system in the fall, but it’s never too late.
