Why is My AC Blowing Warm Air?

Why is My AC Blowing Warm Air

A problem faced by many home and business owners is that their air conditioning system is running, but it is failing to produce cool air. You may be wondering, why is my AC blowing warm air? There are multiple different causes that can lead to your air conditioning system producing warm air instead of cool. At the first sign of an issue with your air conditioning system, contact the professionals at Autumn Mechanical in Spring, TX. Our team of HVAC professionals service all of the communities within the Greater Houston area for your convenience. 


Listed below are some of the most common reasons your air conditioner may be blowing warm air into your home or business:


Incorrect Thermostat Setting or Reading: Air conditioners can easily be switched from cooling to heating, sometimes without the home or business owner ever realizing it. Make sure you check the setting on your air conditioner before contacting a repair company with your issue. Additionally, if there is an issue with your air conditioning unit’s thermostat, it may be unable to cool your space to a desired temperature. This can lead to an uncomfortable climate and difficulty controlling the comfort of your space. Replacing the thermostat is a simple job but you will want to make sure there is nothing more seriously wrong with your AC unit before taking this step. 


Outside Unit is Clogged: The outdoor air conditioning unit must be clean and without obstruction in order for the indoor unit to function properly and expel heat from your space. If the outside unit becomes obstructed with dirt and debris, it may interfere with your unit’s ability to function, which can make it difficult to properly remove heat and cool your home. Keep the area around your outdoor AC unit clean and free of debris to prevent this problem from occurring. Additionally, staying on top of your annual AC maintenance will help our technicians catch early build up in your unit, as well as other problems that may interfere with your unit. 


Loss of Electricity: Your air conditioner could be blowing warm air into your space as a result of the outdoor unit losing power. You may be unaware of this issue, due to the fact your indoor unit is still connected. The outdoor unit may have lost electricity due to a tripped circuit breaker or blown fuse, without any obvious warning. Check the circuit breaker and fuse panel, or call the AC repair specialists in Spring, TX at Autumn Mechanical. Our team can help restore cooling comfort to your space in no time. 


Problem With Evaporator Coil: A problem with your evaporator coil can lead to temperature control issues, such as warm air blowing through your system. Typically, the evaporator coil can become problematic when it is not properly cleaned or whenever the air filter in your space is not changed frequently enough. While you can replace the air filter on your own, you will want to work with a professional air conditioning company to have your evaporator coil cleaned and inspected. 


Low on Refrigerant: Refrigerant plays a critical role in keeping your space cool. This product is used to absorb heat from the air in your home. If it leaks, your A/C will not have enough in order to adequately cool your air. An indicator that you have a refrigerant leak is your indoor and outdoor A/C units have ice forming on them. You’ll need a refrigerant charge to correct the issue. Contact the professionals at Autumn Mechanical to have this issue fixed quickly!
