5 Reasons Why Your AC Is Blowing Hot Air

AC TechnicianWhen you live in Atlanta, Georgia, having a working air conditioner is necessary, especially during the sweltering summer months. But unfortunately, like everything else, HVAC systems can stop working effectively from time to time. One of the most common (and most frustrating) AC issues is when it sends out hot air instead of the cold air it is supposed to circulate. There are a few things that could cause this to happen, and most of them require the help of an HVAC technician to fix them. Read to learn about the most common reasons why air conditioners blow warm air instead of cold air.

Dirty Coils

Your hot air problem may be caused by dirty coils. The coils need unrestricted airflow in order to perform their function properly. The coils can collect dust and dirt over time, making it more difficult for the air to flow freely. Cleaning the coils should be a part of your regular HVAC maintenance plan. Don’t try to clean them on your own since they are located inside the AC unit. Typically, the HVAC technician will clean the coils during your annual tune-up.

Wrong Setting

Often, homeowners jump to conclusions when a serious problem happens, when, in reality, the cause is quite simple. Your air conditioner may be blowing hot air if you accidentally put it on the wrong setting. This is an easy fix, though. Just change the setting from heat to cool. If the switch is already set to cool, you may have a more serious issue at hand.

Power Loss

Another common cause of hot air coming out of your air conditioner is a loss of power. Even if the outdoor unit does not have an electrical connection, the indoor fan can keep blowing. Since the compressor is located outdoors, it will be unable to cool the air, resulting in warm air entering your home. Start by resetting the circuit breaker to see if this solves your issue. If not, you may need to hire an HVAC professional or electrician to repair your AC unit.

Low Coolant Levels

Air conditioners use coolant to get rid of the heat in the air and move the cold air through the ducts and into your home. If your AC is low on coolant, the heat will remain in the air and come into your home instead. Coolant does not typically need to be replaced, so if your levels are low, there is likely a leak somewhere in your system. Hire a professional who specializes in residential HVAC services in Atlanta, to assess your system, locate the source of the leak, and fix it.

Outdoor Clog

Air ConditionerSometimes, the outdoor unit of your AC can become clogged. The outside unit holds the condenser and compressor (the part the cools the air that enters your home). Since this part is outside, it is subject to exposure from dirt, grass, leaves, and other debris. This debris can clog the unit and prevent it from working as it should. To avoid any outdoor clogs, trim the plants that are located around the unit. Regularly clean off the outdoor unit and sweep away any loose debris.
