Living without a functional air conditioner can be challenging during the hottest months of the year. Many different explanations can be had when it comes to determining why your AC unit has suddenly stopped cooling.

If you have experienced a sudden malfunction with your AC system, here are three places where you can start investigating in an attempt to restore your AC unit's ability to cool your living space.

1. You Have a Dirty Air Filter

Modern AC units are equipped with air filters that help to remove debris and contaminants from the air supply used to cool your home. These air filters must be monitored regularly to prevent them from becoming clogged.

If you haven't replaced your AC air filter in a while, the filter may be completely clogged. This will prevent air from moving through the filter, leaving your AC unit without access to the air supply it needs to maintain a cool temperature in your living space.

Keep a supply of spare filters on-hand so that you can replace a clogged filter with a new one whenever your air conditioner fails to properly cool your home.

2. Your Compressor is Obstructed

The air compressor that plays a primary role in the cooling of your home is usually located outside.

Compressors rely on a steady supply of air in order to function properly. Unfortunately, their outside location can sometimes result in serious obstructions that render an AC system unable to generate cool air.

It's important that you keep the area around your outdoor compressor free from shrubs, trees, and other vegetation that could interfere with the movement of air through the unit.

Take the time to regularly clean out the compressor and remove any dirt or debris that may be clogging up the screens. By keeping both your compressor and the area surrounding it free from obstructions, you make it easy for your AC system to cool your home efficiently.

3. You Have Fan Issues

One of the more troublesome causes of a malfunctioning AC system is a problem with the compressor's fan.

A specialized motor helps to rotate interior fan blades to circulate air to and from the cooling chamber in your AC unit. If the fan or motor experiences any complications, no air will be moved through your AC system.

Only an experienced HVAC contractor should be trusted to troubleshoot fan problems so that repairs can be made properly. For more information on AC service, contact a professional near you.
