On a 100-degree afternoon in Burleson, an air conditioner that runs but blows warm air is more than an inconvenience. Here are the six most common causes we see, starting with the easy fixes.
1. The thermostat is set incorrectly
Check that the thermostat is set to Cool and the fan is set to Auto, not On. With the fan on, it keeps blowing air even when the system is not cooling, which can feel warm between cycles.
2. A dirty air filter
A clogged filter chokes airflow across the indoor coil. That can cause the coil to freeze, and once it freezes the system stops cooling. Replace the filter and, if you see ice, turn the system off for a few hours to let it thaw.
3. A dirty or blocked outdoor unit
Your outdoor condenser releases heat from your home. If it is covered in dirt, grass clippings or crowded by shrubs, it cannot do its job. Turn off power to the unit and gently rinse the coil with a garden hose.
4. A tripped breaker to the outdoor unit
Sometimes the indoor fan runs but the outdoor unit has lost power. Check your electrical panel for a tripped breaker. If it trips again right after you reset it, stop and call a technician.
5. Low refrigerant
Refrigerant does not get used up. If levels are low, there is a leak. Signs include hissing sounds, ice on the refrigerant lines and steadily weaker cooling. Refrigerant work requires a licensed professional.
6. A failing capacitor or compressor
A worn-out capacitor is one of the most common summer failures in Texas. If you hear humming from the outdoor unit but the fan is not spinning, a failed capacitor is a likely culprit. It is a quick repair for a professional.
