What to Do When Your AC Is Not Cooling Properly in Fairfield County
When your air conditioner is running but your home still feels warm, it can be both frustrating and uncomfortable—especially in the peak of summer. At Edgerton Heating & Air Conditioning, we’ve seen it all. Here’s how to troubleshoot why your AC is not cooling and when to call a professional.
1. Thermostat Issues
Start with your thermostat—it may be:
- Set to the wrong mode (“Fan” instead of “Cool”)
- Malfunctioning or uncalibrated
- Set too high due to accidental changes or programming issues
Pro Tip: Try lowering the thermostat by 5 degrees to test responsiveness.
2. Dirty or Blocked Air Filter
Air filters should be replaced every 1–3 months. A clogged filter restricts airflow, causing your system to struggle and cool unevenly.
3. Frozen Evaporator Coils
Low refrigerant levels or poor airflow can freeze coils, halting the cooling process. You may notice:
- Ice buildup on indoor or outdoor units
- Warm air from vents
- Frequent short cycling
Let your system rest for a few hours, and call a tech if the issue returns.
4. Refrigerant Leak or Low Levels
Your AC needs the correct refrigerant charge to cool effectively. Signs of low refrigerant include:
- Hissing or bubbling sounds
- Reduced airflow
- Warm air output
Only a licensed HVAC technician can check and refill refrigerant safely.
5. Dirty Condenser Coils
If your outdoor unit is covered in dirt, leaves, or debris, it can’t release heat efficiently. Use a hose to gently rinse off the coil, but avoid damaging the fins.
6. Undersized or Aging System
Sometimes, your AC might be:
- Too small for your home’s square footage
- Nearing the end of its lifespan (10–15 years)
- Inefficient due to poor maintenance history
In these cases, we can help with a system upgrade or redesign that fits your space and budget.
