How a Dirty Air Filter Can Impact Your AC Efficiency

One of the most obvious signs that your air filter is clogged is the inefficiency of your air conditioning system. According to the U. S. Department of Energy, a dirty, blocked filter can cause a 15% increase in energy consumption.

The harder the fan has to work to get air in and out of the ducts, the higher your utility bills will be. Changing or cleaning your air filter is one of the most important steps you can take to maintain your air conditioner. A dirty filter creates a layer of dirt, dust, and dander that restricts the amount of air entering the air conditioner and puts pressure on the fan. This is your first line of defense for keeping an effective and efficient air conditioning system that keeps you and your family comfortable and healthy. A dirty air conditioner filter can cause expensive repairs or a total breakdown when you need your air conditioner most.

It's wise to check your air filter every month and replace it every one to three months, depending on your circumstances. Replacing filters is a simple and affordable step compared to the cost of repairing or potentially replacing your air conditioning system. If your air conditioner has a reusable filter, clean it and let it dry completely before putting it back in. If you're driving for a long time and notice that the air doesn't seem to move no matter how long you start the air conditioner, it could be a sign that the filter is clogged. A dirty filter will restrict the flow of cold air, causing it to accumulate inside the air conditioning unit and lower the temperature.

This means that you'll have to buy models directly from the manufacturer of your air conditioner, not from hardware stores that sell one size fits all. A dirty filter will allow dust, dandruff, and debris to leak into the air duct system. This can lead to poor indoor air quality and can cause allergens to accumulate in the system, which can lead to respiratory problems or even mold in the ducts. If the filter becomes clogged during the cold summer season, the buildup of cold air can cause ice to form on the air conditioning coils or evaporator. To clean your filter, simply remove it from the boiler, remove the dirt and thoroughly clean it by running it through warm water. Try to clean reusable filters at a time when the air conditioner doesn't need to be on anyway, for example, on a cool night.
