Why is my air conditioning not blowing cold air?

Air Conditioner Maintenance in Melbourne, FLIt’s a hot, sunny, typical Florida day (even though it’s January) and you’re looking forward to getting home and relaxing in the comfort of your air-conditioned house. There’s only one problem, and you feel it as soon as you walk in the door – the AC isn’t blowing cold air. The thought of enduring the Florida heat without AC is terrifying. What do you do?

Check the Outside Unit, Thermostat and Air Filter

You can hear the fan blower working inside and the fan in the outside unit is working too, but you’re not getting cold air from the vents in your home. One of the first things you should do is make sure the unit outside is not covered in grass, dust or dirt. Clean the top of the unit off and make sure no tree branches or bushes are covering it. If its fan isn’t working it can’t cool down the refrigerant used to cool the air inside and you’ll need a professional to look at it.

Next check the thermostat, its fan setting and that it’s set to “cool”. See if it’s set at your desired temperature and make sure it’s set to “auto” and not “on”, which can cause your system to blow air when it’s not being cooled.

Another crucial component to your AC is its air filter. If the filter is dirty, it will block the airflow that needs to reach the air handler. If your filter is dirty, replace it with a new one.

Your AC might also need more refrigerant. If it’s leaking refrigerant, you’ll need to call a service technician to check it out.

Electrical and Other Parts

Sometimes other crucial parts like the condenser or compressor break down and stop working properly. The condenser removes heat from the air. When it works properly, it blows warm air outside and brings cool air back into your home. The compressor pushes cold air from the condenser to the air vents in your AC system. If you’re not getting cold air out of the vents, the compressor could be misaligned or not working properly.

Your system could also be having electrical problems. Contacts and connectors might be corroded, the thermostat could be malfunctioning, sensors might have failed, or there’s shorted or broken wires.
