Why Is My AC Blowing Out Warm Air?

It can be frustrating when your AC blows warm air when you expect it to be cool and comfortable air. Various reasons can cause this issue, and it is crucial to address the issue as soon as possible to avoid further damage and discomfort. As a professional HVAC contractor serving Clermont, FL, Enginair Air & Refrigeration understands the importance of a functioning AC and will share some common reasons why your AC may be blowing out warm air.

• Dirty Air Filter

The air filter in your AC traps dust, dirt, and other airborne particles, preventing them from entering your home. However, if the filter becomes dirty and clogged, it can restrict airflow, causing your AC to work harder and blow out warm air. To avoid this issue, it is recommended to change your air filter every 1-3 months, depending on usage.

• Refrigerant Leak

Refrigerant is the substance that chills the air in your AC. If your AC is low on refrigerant or has a leak, it will not be able to cool the air efficiently, resulting in warm air blowing out of your vents. Hire a professional HVAC contractor in Clermont, FL, such as Enginair Air & Refrigeration, to diagnose and repair any refrigerant leaks. Attempting to fix the leak yourself can be dangerous and may cause further damage to your AC system.

• Thermostat Issues

The thermostat is the control center of your AC system, and if it is not functioning correctly, it can cause your AC to blow out warm air. Sometimes, the issues may be as simple as the thermostat being set to “heat” instead of “cool.” However, if the thermostat is malfunctioning, our professional HVAC contractor may need to repair or replace it. If you notice a thermostat issue, call us to schedule air conditioning repair in Clermont, FL, and surrounding areas.

• Clogged Condenser Unit

The condenser unit removes heat from the refrigerant and releases it outside your home. If the condenser unit becomes clogged with dirt and debris, it will not be able to release the heat efficiently, causing your AC to blow out warm air. Schedule regular AC maintenance with the professional HVAC contractor at Enginair Air & Refrigeration to ensure your condenser unit is clean and functioning correctly.

• Electrical Issues

AC systems have various electrical components, including motors, capacitors, and wiring. If any of these components are defective or damaged, it can cause your AC to blow out warm air. It is essential to hire a licensed and experienced HVAC contractor to diagnose and repair any electrical issues with your AC system.
