Air Conditioner Maintenance

  • Change your air filters regularly.
  • Be sure to avoid blocking floor, wall or ceiling vents.
  • Make sure your outside condensing unit isn’t covered or clogged with leaves or debris.
  • Check to make sure the drainage system isn’t clogged.
  • Don’t run your system in cooling mode when outdoor temperatures are lower than 55° F or 13° C.
  • Have a Carrier® expert clean your indoor coil regularly.
  • Check for water at the base of your outdoor unit. Water likely means the support base has shifted since installation and is no longer level.
  • Consider sealing or insulating your ducts.

Furnace and Boiler Maintenance

  • Confirm that the furnace/boiler turns on and off via your thermostat by setting the temperature higher than the current indoor temperature and setting the system to heat mode.
  • Check the temperature of air supply grates or radiant system to ensure you’re able to feel warmth.
  • If you have an older thermostat that could have mercury switches, clean and level it to ensure it works properly.
  • Check all visible wiring and electrical connections for signs of damage like burns, unraveling wires and loose nuts.
  • Check vent connection pipe and chimney for rust or gaps. (Venting systems can deteriorate over time.)
  • If you have a gas or oil furnace, make sure you have a clean air filter in the proper size.
  • When you restart your system each fall, you might consider an inspection of the burners, combustion area, venting and even flame appearance

Humidifier Maintenance

  • Change the water panel before the heating season

Heat Recovery Ventilator (HRV) Maintenance

  • Wash once a year and handle with care. Soak the core in warm water and mild soap for three hours and then rinse under warm (not hot) water.
  • Filters in your ventilator are washable and should be cleaned every three months. Use a vacuum cleaner to remove accumulated dust and then hand-wash in warm water.
  • Regularly check the screen on the exterior intake hood and clean as necessary.

Purifier Maintenance

  • Changing the air filter is the only maintenance required. Filter life varies from home to home and is based on several factors, but most last from eight to 12 months.
