Summer HVAC Maintenance Steps

  1. Check your air filter. During periods of heavy cooling system use, the filter should be inspected monthly to make sure it has not become full of contaminants. You may find it necessary to replace it sooner than the 3-month mark during these times, so have a replacement ready just in case.
  2. Inspect all registers and return air grilles in your home to ensure they have not been blocked or shut. These vents should never be blocked, as doing so will restrict airflow through your HVAC systems, which could create performance issues and system overheating.
  3. Move all carpets and rugs, furniture, and other items away from vents. Check to see that vent louvers are open; if you wish to shut off cooling to unused areas of your home or building, never close more than 20 percent of the structure’s HVAC vents. If you have many unused areas, consider investing in a zoning system which will allow you to reduce energy waste while facilitating proper HVAC system performance.
