Most Common Reasons Your AC Isn't Cooling
1. Low or Leaking Refrigerant
Refrigerant is what actually removes heat from your home. Low levels almost always mean a leak — which requires a licensed technician to locate, repair, and recharge.
2. Frozen Evaporator Coil
Ironically, a coil covered in ice means no cooling. Usually caused by low airflow or low refrigerant. The system needs to be shut down and inspected before it can run again.
3. Dirty or Clogged Condenser
The outdoor unit expels heat. If it's caked in dirt or debris, it can't do its job — your home stays warm even with the system running full blast.
4. Failed Compressor
The compressor is the heart of your AC. If it fails, you'll get air movement but zero cooling. This is one of the more serious repairs — our techs can give you a straight answer on repair vs replace.
5. Undersized or Overworked System
In a Houston summer, an older or improperly sized unit simply may not keep up. Our technicians can assess whether a tune-up helps or if a replacement conversation makes more sense.
What to Do Right Now
Turn your thermostat to "cool" and set it 5 degrees below your current room temperature. Check your air filter — if it's clogged, replace it and wait 30 minutes. If neither helps, call us. Don't let it run if you smell burning or see ice on the unit.
