4 Reasons Your Central Air Is Blowing Hot Air

Central air conditioning is no longer considered a luxury in homes these days, as it is now something people rely on during the summer. Having central air offers an easy way to stay cool, until the system starts blowing hot air instead of cold air. If your system is currently experiencing this problem, here are four reasons it might be happening.

Your thermostat is set on "fan"

Most thermostats have three settings, which are heat, cool, and fan. If someone adjusted the thermostat on purpose or by accident and turned it from cool to fan, you can expect hot air to blow out of the registers during the summer. The fan setting on your thermostat is only designed to move air around in a home, and this air will not be heated or cooled. If this is the cause of your problem, changing the setting to cool will solve the problem.

The condenser is clogged

A second common cause of hot air coming from a central AC system is a clogged condenser. The condenser is the part of your system you will see outside your home. It can get clogged simply from being outside, and a clogged condenser is a big problem for central air. If the system is clogged, it will not be able to cool the air that comes through it.

The system has no coolant in it

For your system to produce cool air, it must have coolant in it, and it must have enough coolant in it. Unfortunately, the coolant in a system can escape from it if there is a leak. If your system has a leak, an HVAC technician will have to first locate the leak and then fix it. After that, they will recharge the system by adding more coolant, and this will solve the problem you are experiencing with your system.

The evaporator coils are dirty or frozen

The fourth thing to know is that hot air will come from your system if the evaporator coils are frozen or dirty. This too is a common issue with central air conditioners, and it often happens when there is a lack of proper airflow to or from the device.

If your system has any of these issues, it could be the cause of your problem. The only way to find out is by contacting a company that offers air conditioning repair services. You can contact one in your area to get services for your system.
