Why Is My AC Not Blowing Cold Air? Fairfield County Homeowner Guide
When summer hits in Fairfield County, the last thing you want is warm air blowing from your air conditioner. If your AC isn’t keeping things cool, there’s likely a fixable issue at play. At Edgerton Heating & Air Conditioning, we’ve helped thousands of local homeowners troubleshoot problems just like this — here’s what might be going on.
Common Reasons Your AC Isn’t Cooling Properly
1. Dirty Air Filter
A clogged air filter blocks airflow and can prevent cool air from circulating. Check your filter and replace it every 1–3 months.
2. Thermostat Settings
Ensure the thermostat is set to “cool” and that the temperature is lower than your current room temperature. Double-check for programming errors too.
3. Frozen Evaporator Coil
If your AC coil is frozen, airflow is restricted. Low refrigerant levels or dirty coils can be the cause — this usually needs a professional diagnosis.
4. Low Refrigerant
Refrigerant is essential to cooling your air. If there’s a leak or low levels, your AC won’t blow cold. This issue requires licensed HVAC repair.
5. Faulty Compressor or Capacitor
Your compressor circulates refrigerant — if it’s malfunctioning, your system may run without cooling. This is a common repair in older systems.
What You Can Do Before Calling a Technician
- Replace or clean your air filter
- Confirm correct thermostat settings
- Inspect for ice buildup on the unit
- Make sure your outside condenser isn’t blocked by debris
If these don’t help, it’s time to contact a professional for diagnostics.
