Why Is My AC Running But Not Cooling? Common Issues in Georgia Homes

Georgia summers bring the heat and plenty of it. So when your AC is running but the house still feels warm, it’s not just frustrating it’s a sign something’s wrong. At Hammond Services, we’ve helped countless homeowners across Griffin, Newnan, and the South Metro Atlanta area troubleshoot this exact problem.

If your air conditioner is blowing air but not cooling your home, here are the most common reasons and what you can do next.

1. Dirty Air Filter

This is one of the simplest causes and one of the most common. A clogged air filter can restrict airflow, making it harder for your AC to circulate cool air.

Fix: Check and replace your air filter every 1 to 3 months, especially during heavy-use seasons.

2. Low Refrigerant or a Refrigerant Leak

Your AC system relies on refrigerant to pull heat from your home. If levels are low due to a leak, your system can’t cool properly—even though it’s running.

Fix: This isn’t a DIY job. Our licensed technicians can inspect for leaks and recharge your system safely.

3. Dirty or Blocked Outdoor Unit

Leaves, pollen, and yard debris can clog your condenser coils, especially after spring storms. If heat can’t escape through the outdoor unit, your AC won’t cool efficiently.

Fix: Clear debris around your outdoor unit and schedule seasonal cleanings to keep it performing at its best.

4. Frozen Evaporator Coils

Ironically, when your system is too cold—due to restricted airflow or low refrigerant—it can freeze up. That ice blocks heat exchange, leaving you with warm air indoors.

Fix: Turn the system off and let it thaw. Then call us to find and fix the root cause before it happens again.

5. Thermostat Problems

If your thermostat isn’t calibrated or is malfunctioning, your AC may run without cooling to the proper temperature or at all.

Fix: Make sure your thermostat is set to "cool" and the temperature is correct. Consider having Hammond Services install a programmable or smart thermostat for better performance.

6. Leaky or Damaged Ductwork

In older homes around Griffin, air ducts may leak cooled air into the attic or crawl space, meaning less cool air actually reaches your living space.

Fix: Duct sealing and insulation can prevent energy waste and improve comfort across your home.
