It can be frustrating if your HVAC system blows out warm air instead of cool air, especially during hot summer months. There are several reasons why your HVAC system may be blowing out warm air. In this blog, we will discuss the common causes and what you can do to fix them.
Why Your HVAC System Blows out Warm Air?
Thermostat Settings
One of the first things you should check when your HVAC system blows out warm air is your thermostat settings. Ensure that the thermostat is set to “cool” mode and that the temperature setting is lower than the current room temperature. Sometimes, the thermostat can accidentally get set to “heat” mode, causing your HVAC system to blow out warm air.
Everything You Ought to Know About HVAC System
Dirty Air Filters
A dirty air filter can cause your HVAC system to blow out warm air. Air filters trap dust, dirt, and other particles, and over time, they become clogged. When this happens, the HVAC system has to work harder to cool your home. This can cause the evaporator coil to freeze up, which can cause warm air to blow out of the vents. Changing your air filters regularly is important to prevent this from happening.
Refrigerant Leak
A refrigerant leak is a more serious problem that can cause your HVAC system to blow out warm air. Refrigerant is the substance that cools the air in your HVAC system. A leak in the refrigerant line can cause the refrigerant level to drop, and your HVAC system won’t be able to cool your home effectively. A refrigerant leak is a serious issue that requires professional help. Call an HVAC technician immediately if you suspect your HVAC system has a refrigerant leak.
Dirty Evaporator Coils
The evaporator coils in your HVAC system are responsible for cooling the air in your home. These coils can become dirty over time, and the dirt and debris can restrict airflow. When this happens, the evaporator coils can freeze, causing warm air to blow out of the vents. Regular maintenance can help prevent this from happening.

Faulty Compressor
The compressor is the heart of your HVAC system. It’s responsible for compressing the refrigerant and circulating it through the system. If the compressor is faulty, it won’t be able to do its job, and your HVAC system won’t be able to cool your home effectively. A faulty compressor is a serious issue that requires professional help.
What to do if your HVAC System blows out warm air?
If your HVAC system is blowing out warm air, you should first check your thermostat settings. Ensure it is set to “cool” mode and the temperature setting is lower than the current room temperature. If this doesn’t solve the problem, check your air filters. In case they are dirty, replace them. If none of these steps solve the problem, it’s time to call an HVAC technician.
An HVAC technician can diagnose the problem and recommend the best course of action. They may need to repair or replace components in your HVAC system. It’s important to have regular maintenance on your HVAC system to prevent issues like this from occurring.
Conclusion
In conclusion, if your HVAC system is blowing out warm air, it can be caused by several different issues. The most common causes are thermostat settings, dirty air filters, refrigerant leaks, dirty evaporator coils, and faulty compressors. Regular maintenance can help prevent these issues from occurring. If you suspect your HVAC system has a problem, call an HVAC technician immediately to diagnose and repair the issue. Or you can also place service using We4U India’s professional HVAC services.
