Changing air filters

Check and Change Your Air Filters Monthly

One of the easiest yet most critical maintenance tasks is inspecting your air filter. A clogged filter restricts airflow, forcing your system to work harder, which increases energy bills and strains components. We recommend checking it monthly and replacing it at least every 90 days to maintain healthy air quality and system efficiency.

Clear Your Outdoor Unit of Debris

Your outdoor condenser unit needs clear space to function properly. Before each season, make sure to remove any leaves, grass clippings, dirt, or branches from the top and sides. Maintaining at least two feet of clearance around the unit ensures proper airflow, which is essential for effective cooling and preventing the system from overheating.
