Essential AC Maintenance Tasks:

Inspect and Replace Your Filters

One of the easiest ways to keep your AC running smoothly is by regularly checking and replacing the air filters. Clean filters improve air quality and system efficiency, and help avoid overworking your unit, which can lead to costly repairs.

Check and Replace Thermostat Batteries

Ensure your thermostat is in good working order by checking and replacing its batteries if necessary. A functioning thermostat is key to maintaining optimal comfort and controlling energy use.

Clear the Area Around Outdoor Units

Keep at least two feet of space around your outdoor AC unit. Remove any debris, leaves, or branches that might obstruct airflow. This simple step is crucial for maintaining the unit’s efficiency and preventing overheating.

Inspect Cooling Coils and Fins

Check the evaporator and condenser coils for dirt and debris buildup, which can reduce the system’s ability to absorb and release heat. Gently clean the coils and straighten any bent fins with a fin comb to improve airflow.

Check the Coolant Lines

Inspect the refrigerant lines leading to the house. Look for signs of leakage, wear, and insulation degradation. Properly insulated and intact lines are essential for efficient system operation.
