1. Replace Your Air Filter

A dirty filter restricts airflow and forces your system to work harder.

2. Clear Debris Around Your Outdoor Unit

Leaves, grass, and dirt can reduce airflow and system performance.

3. Check Your Thermostat

Make sure your thermostat is operating correctly and programmed for summer comfort.

4. Inspect Air Vents

Blocked vents can create uneven temperatures throughout your home.

5. Schedule Professional Maintenance

A tune-up helps identify issues before they become expensive repairs.

6. Check for Unusual Noises

Grinding, rattling, or squealing sounds should be inspected immediately.

7. Test Your AC Before Peak Heat

Running your system now allows time to address any concerns before temperatures spike.
