Most common cause in North Texas: Low refrigerant, dirty coils, or a failing capacitor.
Donโ€™t keep running the system โ€” it can cause permanent damage.

โœ… 60-Second Checklist โ€“ Do These First

  1. Thermostat โ€“ Set to โ€œCoolโ€ and 5โ€“7 degrees below room temperature?
  2. Air Filter โ€“ Replace it if dirty (this fixes 40% of no-cooling calls).
  3. Outdoor Unit โ€“ Is the fan spinning? Any ice on the coils? Loud buzzing?
  4. Breaker โ€“ Make sure the AC unit has power at the breaker box.

The 5 Most Common Reasons Your AC Has No Cooling
