If your air conditioner is running but your home isn't getting any cooler, you're not alone. This is one of the most common HVAC complaints we hear from homeowners in Carrollton, GA and surrounding areas — especially during the hot Georgia summers.
Before you panic, there are several things you can check yourself. And if the problem requires professional help, All Seasons Heating & Cooling is here to help with fast, affordable AC repair.
1. Dirty Air Filter
The most common reason your AC isn't cooling properly is a dirty air filter. When the filter is clogged with dust and debris, it restricts airflow to the evaporator coil, reducing your system's ability to cool the air.
Fix: Check your air filter and replace it if it's dirty. We recommend changing your filter every 1–3 months, depending on your home environment.
2. Thermostat Settings
It sounds simple, but incorrect thermostat settings are a surprisingly common cause of cooling problems. Make sure your thermostat is set to "cool" mode and the temperature is set below the current room temperature.
Fix: Verify your thermostat settings. If you have a programmable thermostat, check that the schedule hasn't been accidentally changed.
3. Dirty Condenser Coils
Your outdoor unit's condenser coils release heat from your home to the outside air. If they're covered in dirt, grass clippings, or debris, they can't release heat effectively.
Fix: Turn off your system and gently clean the outdoor unit with a garden hose. Keep vegetation at least 2 feet away from the unit.
4. Low Refrigerant
If your AC is low on refrigerant (commonly called Freon), it won't be able to absorb enough heat from your indoor air. Low refrigerant usually means there's a leak somewhere in the system.
Fix: This requires professional service. Call All Seasons at (770) 809-1355 for a refrigerant check and leak repair.
5. Frozen Evaporator Coil
A frozen evaporator coil can't absorb heat, which means your AC blows warm air. This is usually caused by restricted airflow (dirty filter) or low refrigerant.
Fix: Turn off your AC and let the coil thaw completely. Check your air filter. If the problem recurs, call a professional.
6. Faulty Compressor
The compressor is the heart of your AC system. If it's failing, your system won't be able to circulate refrigerant and cool your home.
Fix: Compressor issues require professional diagnosis and repair. Contact All Seasons for expert compressor service.
7. Leaky Ductwork
If your ducts have holes or gaps, cooled air can escape into your attic or crawl space before reaching your living areas. This is especially common in older homes.
Fix: Have your ductwork inspected and sealed by a professional. This can improve efficiency by 20–30%.
8. Undersized System
If your AC has never cooled your home adequately, it may be too small for your space. An undersized system runs constantly but can never reach the desired temperature.
Fix: Contact All Seasons for a load calculation to determine if your system is properly sized for your home.
