Life can get unbearable quickly when your home’s air conditioner has failed. There are some common reasons why an AC unit quits working well or at all. Here are some reasons, including ones you can handle yourself before calling in a professional.

1. Filter

Just like your furnace, your AC unit has a filter that needs to stay clean, as dirty ones cause reduced airflow. Depending on the make and model, the filter may need to be cleaned or replaced every month or every three months. Some AC units have a reusable filter while others are replaceable.

2. Frozen Evaporator Coil

Your air conditioner’s evaporator coil has refrigerant in it. If there isn’t enough warm air flowing around this, then it can become frozen, with a layer of ice forming. Turn off the A/C on your thermostat, and turn the fan to “Auto.” This will melt the ice. You can then clean any dirt or debris.

3. Low Refrigerant

The refrigerant in your unit is what removes heat from your home. If there are leaks in the refrigerant line, there won’t be enough refrigerant to do the job. Just adding a refrigerant won’t solve the problem as there is likely to be at least one leak.
You’ll need an HVAC professional to find and seal refrigerant line leaks. McGowan’s Heating & Air Conditioning helps homeowners with this issue in the Jacksonville area.

4. Blower Motor Isn’t Turning On

A tripped breaker is usually the cause of this problem. Check your fuse panel and see if the blower breaker has been tripped to the halfway position. If so, turn it off and then on. If it keeps flipping when you start your AC unit, the breaker needs to be replaced.
