We’ve put together a list of the most likely causes of this concern.
Why My A/C System Might Be Blowing Warm Air
- Clogged Outdoor Unit – Keep the area around the outdoor unit clear of debris. If the unit becomes clogged with dirt or other contaminants, it will struggle to remove heat from the home.
- Dirty Evaporator Coil – A dirty evaporator coil is primarily caused by a dirty air filter. The evaporator coil requires professional cleaning.
- Lack of Power to Outdoor Unit – If the outdoor unit loses power and the indoor unit continues to operate, the air conditioner may blow warm air. This can be the result of a tripped circuit breaker or blown fuse.
- Low Refrigerant – Because refrigerant absorbs heat from the home, leaks will negatively impact air conditioner effectiveness. Ice forming on the indoor and outdoor units are signs of a leak and require a professional refrigerant charge to resolve the problem.
- Thermostat Setting – Check to make sure your thermostat is set to cool rather than heat. Verify that it is set to auto instead of on. The on setting causes the fan to blow whether the air conditioner is cooling or not and results in warm air blowing from the vents.
