Why Is My Air Conditioner Not Cooling? 7 Common Issues for Fairfield County Homeowners

air conditioner not coolingIt’s one of the most frustrating HVAC issues: your AC is on, but your home still feels hot and humid. If your air conditioner is not cooling, there are several common causes—and the good news is, most are fixable.

Here’s what our Fairfield County techs see most often.

1. Dirty Air Filter

A clogged air filter can block airflow and prevent cool air from circulating. Change your filter every 1–3 months to keep your system running efficiently.

2. Thermostat Problems

Make sure it’s set to “cool,” the temperature is correct, and the batteries (if any) aren’t dead. A misreading thermostat could be sending the wrong signals.

3. Refrigerant Leaks

Low refrigerant levels will stop your system from cooling effectively. If your AC is blowing warm air or you hear hissing, call a licensed tech.

4. Dirty or Blocked Condenser Coils

The outdoor unit needs to release heat to cool your home. If the coils are covered in debris or grime, it can’t do its job.

5. Frozen Evaporator Coils

Low airflow or refrigerant issues can cause the indoor coils to freeze. If you see ice around the unit or water leaks, shut the system off and call us.

6. Electrical Issues

Tripped breakers, damaged wires, or a failing capacitor could prevent your unit from starting or running correctly.

7. Aging System

If your AC is over 10–15 years old, it may be time for a replacement—especially if repair bills are piling up.

What to Do if Your AC Isn’t Cooling
