AC Maintenance Checklist for Homeowners

Monthly Maintenance Tasks

1. Check & Replace Air Filters – Dirty filters block airflow and make your AC work harder. Replace or clean filters every 1-3 months.

2. Inspect Vents & Registers – Ensure vents are open and free from dust or obstructions to maintain proper airflow.

3. Monitor Thermostat Settings – Test your thermostat to make sure it’s functioning correctly and set at an optimal temperature.

Seasonal Maintenance (Before Summer & Winter)

1. Clean the Outdoor Condenser Unit – Remove dirt, leaves, and debris from the unit to improve efficiency.

2. Check Refrigerant Levels – Low refrigerant can reduce cooling power. If you notice weak airflow or warm air, have a technician check it.

3. Inspect Electrical Components – Tighten loose connections and look for frayed wires or signs of wear.

4. Clean the Evaporator Coils – A buildup of dirt on the coils can reduce cooling efficiency.

5. Clear the Drain Line – A clogged condensate drain can cause water leaks and mold growth.

6. Lubricate Moving Parts – Proper lubrication reduces wear and prevents overheating of motorized components.

7. Test System Startup & Shutdown – Run your AC to ensure it turns on and off smoothly without strange noises or delays.

Annual Professional Maintenance

While many tasks can be done by homeowners, some require a professional touch:

1. Schedule a Professional AC Tune-Up – A certified HVAC technician should inspect and service your AC annually.

2. Test Safety Controls – Ensure that all safety features are functioning correctly.

3. Inspect & Adjust Blower Components – A well-balanced blower ensures even cooling throughout your home.
