Why Is My AC Blowing Warm Air?

During the hot summer months, a properly functioning air conditioner is essential for comfort. If your AC is blowing warm air, it can feel like an immediate crisis. Fortunately, this is a common HVAC issue with several potential solutions that you may be able to troubleshoot yourself.

Troubleshooting Tips for Your AC Unit

If your AC isn’t blowing cool air, try these steps to identify and resolve the issue:

1. Inspect Your Thermostat

First, check your thermostat settings:

• Ensure it’s set to “cool” rather than “heat.”
• Verify the temperature is set lower than the current room temperature.
• Make sure the batteries are functioning and the settings are on “auto,” so the fan only runs when cooling.

2. Locate Your Breaker

Air conditioners require a significant amount of power to run. If the breaker has tripped, it will cut off power to the unit:

• Locate your electrical panel and check for a tripped breaker.
• If the AC breaker is off, switch it back on to restore power.
• If the breaker continues to trip, contact an HVAC technician to prevent further issues.

3. Check Your Coils and Air Filter

A dirty air filter can cause the evaporator coil to become blocked, reducing airflow and potentially freezing the coil. Blocked coils prevent efficient cooling, so check your air filter:

• Replace your air filter every 2-3 months, or monthly in high-use seasons.
• Schedule regular cleaning to keep the evaporator coil clear of dust and debris.

4. Have a Professional Repair Refrigerant Leaks

Low refrigerant is a leading cause of ACs blowing warm air. Refrigerant leaks can be hazardous and should only be handled by professionals. Signs of a refrigerant issue include:

• Warm air from the vents.
• Hissing or gurgling sounds near the unit.
• Ice on the refrigerant line.

If you suspect a refrigerant leak, don’t attempt a DIY fix. Contact an HVAC professional to resolve the issue safely.
