Why Your AC Isn’t Blowing Cold Air & What You Can Do About It

There’s nothing worse than expecting relief from your AC in the Florida heat—only to feel warm air coming from the vents. If your AC is not blowing cold air in Palm Beach, don’t sweat it. This guide breaks down the most common causes, simple steps you can take, and when to call the pros at Pure Tek Air.

Common Reasons Your AC Isn’t Cooling Properly

1. Dirty or Clogged Air Filter

A blocked air filter reduces airflow, forcing your system to work harder and reducing its cooling ability. In humid Palm Beach conditions, replace filters every 1–2 months to maintain efficiency.

2. Incorrect Thermostat Settings

It might sound simple, but check your thermostat first. Ensure it’s set to “Cool” and the fan is on “Auto”—not “On,” which can circulate warm air.

3. Low Refrigerant Levels or a Leak

Your AC needs refrigerant to cool air. If levels are low due to a leak, the system won’t function correctly. This issue requires licensed HVAC technicians to diagnose and refill the refrigerant.

4. Frozen Evaporator Coils

Restricted airflow or dirty coils can lead to ice buildup, preventing proper cooling. Frozen coils often signal an underlying airflow or refrigerant problem.

5. Malfunctioning Compressor

The compressor is the core of your system. If it fails, your AC won’t be able to cool at all. This serious issue demands professional attention.

DIY Fixes to Try Before Calling a Technician

Before scheduling a service, try these simple steps:

  • Replace or clean your air filter
  • Verify your thermostat is set correctly
  • Make sure all vents are open and unobstructed
  • Clear debris from around your outdoor unit
  • Check the circuit breaker and reset if needed

If these don’t restore cold air, it’s time to call in a professional.

When You Should Call an HVAC Expert

Contact an HVAC specialist if you notice:

  • Warm air persists after troubleshooting
  • Ice forming on coils
  • Strange noises like grinding or hissing
  • Water is pooling near the unit
  • System short cycling (turning on and off frequently)

These symptoms usually indicate larger system issues that need expert diagnosis.
