When the temperatures climb in Canton, GA, a well-functioning air conditioner is essential for keeping your home comfortable. But what do you do when your AC isn’t cooling properly? It’s a frustrating problem that can leave your home hot and stuffy during the worst of the summer heat.
At Air Pros GA, we understand how critical a reliable cooling system is, especially in Canton’s humid climate. This comprehensive guide will help you understand the common causes behind an AC not cooling in Canton, GA, walk you through safe troubleshooting steps, and show you when it’s time to call in the experts.
Understanding the Importance of a Properly Cooling AC in Canton, GA
Canton homeowners face long, hot summers with high humidity that can make indoor discomfort unbearable without proper cooling. An air conditioner that isn’t cooling efficiently not only wastes energy but can also cause health issues due to poor indoor air quality and excessive heat.
Ignoring cooling issues can lead to:
- Rising energy bills from an overworked system
- Uneven temperatures and humidity buildup
- Potential damage to your AC system requiring costly repairs or replacement
Addressing cooling problems quickly ensures you stay comfortable and save money on energy and repairs.
Common Reasons Your AC Is Not Cooling Properly
If your AC isn’t cooling, several common issues could be to blame. Knowing what to look for can help you decide whether you can fix it yourself or need professional service.
Dirty or Clogged Air Filters
Dirty filters are one of the most frequent causes of poor cooling performance. When filters get clogged with dust and debris, airflow reduces drastically. This puts extra strain on the system, reduces efficiency, and can even cause the evaporator coils to freeze.
Signs:
- Reduced airflow from vents
- Increased energy bills
- Dust buildup around vents
Fix: Replace or clean your filters every 1-3 months during heavy use seasons. This is a simple, effective first step to improving cooling.
Refrigerant Leaks and Low Refrigerant Levels
Your AC needs refrigerant to absorb heat from inside your home and release it outside. If the refrigerant level is low due to leaks, your system can’t cool properly.
Signs of refrigerant leaks:
- AC blowing warm air
- Hissing or bubbling noises near the outdoor unit
- Ice buildup on coils or refrigerant lines
Important: Only licensed technicians should handle refrigerant because it requires special equipment and EPA certification to manage safely.
Frozen Evaporator Coils
Frozen coils happen when airflow is restricted or refrigerant is low. Ice forms on the evaporator coil and blocks heat transfer, causing your AC to blow warm air or stop cooling entirely.
How to recognize frozen coils:
- Ice buildup visible on indoor coil or refrigerant lines
- AC running continuously without cooling
- Strange noises during operation
If you notice this, turn off the system to let the ice melt and call Air Pros GA for a professional inspection.
Thermostat Malfunctions
Sometimes, the issue isn’t with your AC but with the thermostat controlling it. Incorrect settings or a faulty thermostat can cause your AC to run too little or too much, failing to cool the home properly.
Troubleshooting:
- Verify thermostat is set to “cool” and at the correct temperature.
- Replace batteries if it’s a battery-operated model.
- Consider upgrading to a smart thermostat for better control.
Other Mechanical or Electrical Issues
Compressor problems, fan motor failures, clogged condensate drains, or electrical faults can also prevent proper cooling. These issues are typically beyond DIY fixes and require professional diagnosis.
Step-by-Step Troubleshooting Guide for Homeowners
Before calling a professional, you can take some safe, simple steps to identify or fix common issues:
Turn Off Power for Safety:
Before inspecting the unit or changing filters, switch off the power at the breaker to avoid injury.
Check and Replace Air Filters:
Dirty filters are an easy fix that improves airflow and cooling.
Reset or Recalibrate the Thermostat:
Make sure the thermostat is set correctly, and try resetting it if possible.
Inspect the Outdoor Unit:
Clear any leaves, dirt, or debris blocking airflow around the condenser unit.
Look for Ice or Frozen Coils:
If ice is visible, turn off the system to let it thaw before restarting.
Avoid DIY Refrigerant Repairs:
If you suspect a refrigerant leak, call Air Pros GA to safely diagnose and repair.

Why does my AC blow warm air instead of cool?
Warm air can be caused by dirty filters, low refrigerant, frozen coils, or thermostat issues. Checking filters and thermostat settings is a good start.
Can a dirty filter cause my AC to stop cooling?
Yes. Dirty filters restrict airflow, causing the system to work harder or freeze up, which reduces cooling.
How long can frozen coils damage my AC?
Frozen coils cause strain and can damage compressor components if not addressed within a few days.
What should I do if my AC has a refrigerant leak?
Turn off the system and call a licensed HVAC professional immediately. Refrigerant leaks require expert repair and safe handling.
