The Care and Keeping of Your HVAC


You can enjoy the benefits offered by an HVAC system if it is in good working condition. To keep your system in tip-top shape, follow this easy, workable preventative HVAC maintenance plan.

What to do NOW

  • Purchase a high-quality and high-efficiency pleated air filter
  • Remove any blockages, such as leaves, grass, pollen, and stones
  • Make sure that approximately 2 feet of the area surrounding your outside system is clear of clutter

Monthly and Seasonal HVAC Maintenance

  • Examine refrigerant lines every month
  • Change your filters at least every 3 months
  • Turn the water off on the furnace humidifier during summer
  • Change the humidifier filter and turn the water on during fall

Annual Maintenance

  • Change your carbon monoxide detector battery
  • Make sure that your outdoor AC is placed on solid, flat ground
  • Mix bleach and water to clear the air conditioning condensate drain

Tips on Keeping Your HVAC System Healthy

  • Make sure your filter is excellent. If not, replace it with a superior quality filter. Superior quality pleated filters have an electrostatic charge. This functions like a magnet so they can grasp very small particles, including those that transmit germs and bacteria.
  • Check the filter every month and depending on the model of filter follow a 30, 90 or 180 day period when replacing the filter . Replace the filter as soon as it looks dirty and clogged. You will need to change the filter more frequently if you have pets.
  • Leave at least 2-feet clearance around the external AC unit and heat pump. Clear the top and sides of the external AC units and pumps by removing rubble and litter, such as stones, leaves, twigs, and pollen during spring, summer, and fall. Avoid unloading cut grass or clippings near the HVAC.
  • Examine the insulation of on the refrigerant lines that lead into your home. Replace it immediately if it is damaged or missing.
  • Ensure that the system is flat on the floor. Examine your external AC unit and heat pump annually to make sure that they are on level and firm ground.
  • Remove any clogs and blockages. Mold and algae accumulate on your system. Remove this by mixing a cup of bleach with water then pour it into the AC condensate drain. Do this once a year. Set the humidistat between 35-40% relative humidity then switch on the water supply.
  • In summer, turn the water supply to the furnace humidifier off. Alternatively, change the humidifier wick filter in fall.
  • Prevent adding unnecessary strain on your system. Avoid closing more than 20% of your home’s registers.
  • Change the battery in your carbon monoxide detector every year.
  • Have a reliable heating and cooling provider service your system yearly. American Air will send an expert HVAC technician to your home to conduct an inventory on your system and examine its status. If you need information, do not hesitate to ask the technician.

Practicing the above preventative HVAC maintenance tips will help in lengthening the lifespan of your system.
