In the warm summer months, our air conditioner systems ensure we stay cool and comfortable. However, sometimes issues arise, such as the air conditioner blowing hot air. When this happens, it’s usually due to a handful of possibilities.
One common cause of an AC system that blows warm air is a refrigerant leak. This could be the result of any number of culprits including leaky valves, rusted tubes, and loose fittings and connections. Air conditioners do not use up refrigerant, meaning if your AC is low, it has a leak somewhere which needs diagnosis and repair.
Sometimes, a problem with the AC blowing warm air is as simple as the thermostat being set incorrectly. It’s very easy to do, as well as easy to fix. Be sure your thermostat is switched to the Auto setting, not the On setting. When in the On position, the fan blows air constantly and is more for air movement than cooling. Also, check the thermostat’s programming and make sure it’s correct.
Compressor and Condenser Problems
Several possible issues involving these components could result in warm air blowing from the AC. An interruption in the supply of power would cause problems. These could be from rodent-chewed wires, switched-off power, or tripped circuit breakers.
Dirty, clogged coils also pose a problem for the AC unit. This is one important reason periodic cleaning and maintenance is necessary. A severely dirty unit with clogged coils can impair the AC unit’s ability to cool.
When your AC blows warm air, it can be frustrating. Several possible issues could be to blame. Begin with the easiest by checking the thermostat, moved on to cleaning your unit, and if that does not work, call in a professional to diagnose and repair the problem.
