HVAC maintenanceYour HVAC system is likely the most expensive appliance in your Tallahassee, Florida, home, and the one that uses the most energy. The U.S. Department of Energy (DOE) estimates that half of the annual energy consumption costs in the average home go toward heating and cooling needs. These tips for extending HVAC system lifespan can also increase efficiency and lower energy costs in y our home throughout the year.

  • Change the air filter. Nothing raises energy consumption and wears out the system faster than a dirty air filter. Check the air filter monthly and change it when it is dirty. Verify that the filter is the exact size needed for your system by checking the manual or asking your HVAC contractor.

  • Check the outdoor condenser. Central air conditioners and heat pumps use an outdoor condenser that needs to be kept clean for maximum system life and energy efficiency. The condenser needs ample airflow through it to cool the hot refrigerant as warm air is removed from your home. Remove any vegetation or objects that block the sides and top of the outdoor unit. Keeping the coil inside the condenser clean with a light spray from the hose periodically is one of the best tips for extending the lifespan of your HVAC system.

  • Leave vents open. Resist the temptation to close vents or supply registers in rooms you don't use. Doing so actually increases wear and tear on the system -- especially the ductwork. Air pressure increases throughout the system, harming many of its components. Saving energy is important, so verify that the registers aren't blocked by furnishings. Keeping these elements clean also helps to improve air quality and system efficiency. Excessive dust around ducts usually indicates ductwork leaks, which lowers system longevity and raises energy bills.

  • Have the system serviced annually. HVAC professionals clean and tune the system so that it is as close to factory standards as possible. Small problems are easier and less expensive to fix before they escalate into something larger.
