What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Check Air Filters

Begin by inspecting and replacing your air filters if they are dirty. Clogged filters can restrict airflow, leading to poor cooling performance.

2

Examine Thermostat Settings

Ensure your thermostat is set to the desired temperature and is functioning properly. Sometimes, recalibrating or replacing the batteries can resolve issues.

3

Inspect Drain Line

Look for any blockages in the condensate drain line. Clear any debris to prevent water pooling and potential water damage.

4

Listen for Unusual Noises

Turn on your AC and listen for any strange sounds. If you hear grinding or squealing, it may indicate a mechanical issue that needs professional attention.

5

Check for Refrigerant Leaks

If you notice a drop in cooling efficiency, check for signs of refrigerant leaks, such as ice buildup on the coils. This usually requires a technician.

Pro Tip
Always turn off power to the unit at the breaker before inspecting any components. Safety first — even for simple checks.
