There can be a number of potential causes for the AC blowing warm air. Some causes are a simple fix not requiring a call for repair. Others can only be repaired by a certified HVAC technician. Garland Heating and Air Conditioning is available for your HVAC needs, and provides emergency services 24/7 for your convenience.
Almost everyone has turned the thermostat off, and the fan on manual at some time. Whether it is to help pull out the smoke of a burned meal, or just to bring fresh air in on a mild day, it is easy to forget it and numerous people do. The fan should be set at auto. When the fan is set to the “on” position, and the AC is off, the fan will blow warm air. Check the thermostat before calling your HVAC technician. In addition, check battery operated thermostats for a low battery warning, and change the battery if indicated.
An airflow restriction can cause problems with the unit, including the shutdown or failure of the compressor, leading to the AC blowing warm air. The first thing to check is the air filter. An excessively dirty filter may be the cause of the AC blowing warm air.
An additional cause for the AC blowing warm air can be dirty coils. By routinely changing the air filter you can delay this issue, and by scheduling annual maintenance you can potentially avoid it all together. In addition, when extreme dusty conditions prevail, check the filter more often. During remodeling, its best to cover the air registers and leave the system off if possible while work is actively occurring.
Refrigerant doesn’t get “used up”. If your AC is low on refrigerant it is either undercharged or has a leak. Either condition can result in damage to the AC system, and may be the cause of the AC blowing warm air. A refrigerant leak will require repair, and the system recharged with refrigerant.

A bad compressor can cause the AC blowing warm air. Compressor failure is a typical reason why a new air conditioning installation is selected by homeowners. The compressor is a costly item to replace, and when installed on an aging system can create additional problems. Replacement is the ideal solution in all but fairly new systems.
Annual maintenance ensures your HVAC system of obtaining the longest possible lifespan, and greatest energy efficiency and performance. Furthermore, it reduces wear and tear, and often enables the technician to identify components with wear before a breakdown occurs. If your system is in need of maintenance, call now to schedule air conditioning service.
