Air Conditioning Repair | AC Blowing Warm Air
Over the decades since air conditioning was invented, people have become so dependent upon it that it’s difficult to tolerate the heat when you need air conditioning repair. It is used almost everywhere in our lives and when experiences a problem and the AC is blowing warm air on a hot day, it rapidly becomes intolerable for u, and especially for family members with chronic health problems. By using the following tips, you may be able to restore your air conditioners cold air, and avoid having to call for air conditioning repair in Dallas.
Check the Thermostat
The thermostat is one of the most overlooked components of the HVAC system. Yet it is both a component that will eventually have to be replaced, and is a source of numerous problems simply due to our own forgetfulness. First, ensure it is set to the Cool function. Someone may have turned it off to run the fan and forgotten to turn it back. If this is the case and the fan is on manual rather than automatic, this will be the cause of the ac blowing warm air. Next, check the temperature. For example, if it is set at 79 degrees, and the inside temperature is 75, the unit will not cut on unless the temperature reaches 80 or above. Finally, check the fan. If the fan is set to manual rather than automatic, it will blow warm air until the compressor runs producing cold air.
After ensuring the thermostat temperature is set lower than the room temperature, and that the fan is on automatic, if the AC blowing warm air continues, check the following:
Check the Filter & Breaker
Check the air filter, and ensure it is clean. A dirty filter can prevent the proper air flow, causing the system to overheat and throw a breaker. Some split systems have a switch inside the indoor portion of the system. It will typically look similar to a light switch. In some systems, if the breaker is thrown the fan may run, but not the compressor, resulting in the AC blowing warm air. If the switch has been thrown, switch back to on. If nothing occurs, proceed to the next step.
The External Breaker
Check the breaker on the outdoor condenser. There should be a box containing a breaker, located on a wall or near the outside unit. If the breakers has been thrown, switch it to the on position. Numerous factors can throw a breaker, while it may be a problem with the air conditioner, the power service may have fluctuated when a power surge occurred. If these tips fail to restore cooling call your HVAC technician for repair when your AC is blowing warm air.
Tips for Best Performance
To ensure the proper operation of your HVAC system, do not block the area around the air return (the area where the filter is located). Blocking the air return will impair its airflow, and can cause the system to overheat potentially resulting in damage to the system or even fire. Overheating can cause a breaker to be thrown, resulting in the AC blowing warm air.
Keep registers’ clear of obstruction. Drapes, furniture or other objects covering the registers will affect the system and may cause problems within the system itself.
The HVAC system requires annual maintenance for safe and effective performance. During exceptionally hot summers or cold winters or when dusty remodeling has occurred within the home, have your system inspected more frequently to avoid damage and maintain performance.
Over time dust and grime collect on cooling coils, especially if the filter hasn’t been routinely changed. Dirty coils will result in poor performance and other potential problems, including the AC blowing warm air. Your technician will check your coils during routine maintenance to assess if they need cleaning.
