Why Is Your AC Blowing Warm Air?

If your AC is blowing warm air, there could be several reasons behind it. This post will discuss some of the common causes of warm air coming from your AC and what you can do to fix it.

Dirty Air Filter

One of the most common reasons for warm air blowing from your AC is a dirty air filter. The air filter in your AC system helps to trap dust, dirt, and other particles before they reach the evaporator coil. Over time, the filter can become clogged with debris, hindering proper airflow and causing your AC to blow warm air.

Refrigerant Leak

Refrigerant is the chemical responsible for cooling the air in your AC system. If there is a leak in your refrigerant line, it can cause your AC to blow warm air instead of cool air. A refrigerant leak is not only a problem for your comfort but can also be damaging to your system if left untreated.

Faulty Thermostat

The thermostat is the control center of your AC system, telling it when to turn on and off and at what temperature. If your thermostat is not functioning properly, it could be sending incorrect signals to your AC, causing it to blow warm air. This can be a simple fix, such as replacing the batteries in your thermostat or recalibrating it.

Clogged Condenser Unit

The condenser unit is located outside and is responsible for releasing hot air from your AC system. If the condenser unit is clogged with dirt, leaves, or debris, it can hinder its ability to release heat properly. This can result in warm air blowing from your AC.

Ductwork Issues

The ductwork in your home is responsible for distributing cold air throughout your house. If there are leaks, tears, or damage to the ducts, it can cause cool air to escape and warm air to enter. This can be a common issue in older homes with aging ductwork.

Dirty Evaporator Coil

The evaporator coil is located inside your AC system and is responsible for cooling the air that passes through it. Over time, the evaporator coil can become dirty, hindering its ability to cool the air and causing warm air to blow from your AC.

When to Call a Professional

If the above steps do not solve the issue of your AC blowing warm air, consider calling a professional HVAC technician. They'll be able to properly diagnose and repair any issues with your system. In addition, regular maintenance by a professional is crucial for keeping your AC in good working condition and identifying any potential problems before they become bigger and more expensive issues.
