It’s one of the most frustrating summer problems — your AC is running, but your home still feels like a sauna. If you’ve cranked down the thermostat but the air still isn’t cool, here are a few common reasons why that might be happening:
- Dirty Air Filter
Your air filter works hard to trap dust and debris. But when it gets clogged, it can restrict airflow, causing your AC to struggle and blow warm air. Check your filter monthly and replace it as needed — it’s one of the easiest ways to keep things running smoothly. - Low Refrigerant
Refrigerant is what helps your AC cool the air. If your system is low, likely due to a leak, it won’t be able to chill your home properly. This isn’t something you can top off like gas — it requires a professional to diagnose and repair. - Dirty Outdoor Unit
If your outdoor unit (condenser) is covered in dirt, leaves, or debris, it can’t release heat effectively. A quick cleaning can sometimes make a big difference — just be sure to turn the power off first, or better yet, call us! - Thermostat Issues
Sometimes the issue isn’t the AC at all — it’s the thermostat. Double-check the settings and batteries. If you have a smart thermostat, make sure it’s connected and functioning properly. - Electrical or Mechanical Problems
Faulty capacitors, worn-out motors, or electrical issues can all prevent your system from working correctly. These usually need a trained tech to inspect and fix safely.
