Few things are more frustrating than turning on your air conditioner only to feel warm air blowing from the vents. When your AC isn’t cooling properly, it usually points to a repair issue that shouldn’t be ignored. Here are the most common causes and what you can do about them.
Low Refrigerant Levels
If your system is low on refrigerant, it won’t have enough cooling power to bring down indoor temperatures. This often means there’s a leak. A professional AC repair is the best way to diagnose and fix the issue.
Dirty Air Filters
Clogged filters restrict airflow, making your system work harder and causing warm air output. Replacing your filter regularly is an easy, affordable fix that also improves indoor air quality.
Thermostat Issues
Sometimes the problem is as simple as a thermostat set to the wrong mode. Double-check your settings, and if the issue persists, a technician may need to recalibrate or replace it.
Frozen Evaporator Coils
When coils freeze due to poor airflow or refrigerant problems, your AC won’t be able to cool effectively. Turning the unit off and calling for HVAC maintenance prevents further damage.
Electrical or Compressor Problems
If your AC is still blowing warm air after checking the basics, the issue may be with the compressor or electrical components. These require immediate attention from a licensed technician.
