What Happens to Your AC if the Filter is Clogged

What Happens to Your AC if the Filter is CloggedAs a homeowner, it’s easy to overlook the air filter in your air conditioning unit. But did you know that a dirty air filter can cause significant problems with your HVAC system?  The ac air filter is not just to help keep the air clean. Regularly replacing or cleaning the air filter before it turns into a dirty ac filter is one of the most important steps you can take to maintain your air conditioner in tip top shape.

Reduced Air Flow

One of the most significant problems with a dirty air filter is reduced airflow. When the filter becomes dirty and clogged with dust and debris, it places an additional strain on your HVAC system, making it harder for your unit to work properly and efficiently. Over time, this increased wear and tear can lead to a complete breakdown of your system, resulting in costly repairs.

High Energy Bills

A dirty air filter can also lead to high energy bills. When your unit has to work harder than usual, it uses more power to cool your home, resulting in higher energy bills. According to the US Department of Energy, a clogged air filter can cause a 15% increase in energy usage.

Short Cycling

Frequent cycling is another problem that can result from a dirty air filter. Your HVAC system will cycle on and off throughout the day, but a dirty filter can cause those cycles to become more frequent, leading to noise pollution, wasted energy, and uncomfortable temperature changes.

Frozen AC

A dirty air filter can also cause your AC unit to freeze up. When the filter is clogged, it restricts the flow of cold air, causing it to build up inside the unit and lower the temperature. If this happens during the summer cooling season, it can lead to ice forming on the AC coils or evaporator, reducing the HVAC system’s ability to remove heat from the air and eventually causing your air conditioner to break down.

Decreased Comfort

A dirty air filter can also result in decreased comfort for you and your family. Restricted airflow means less cool air and increased strain on the blower, resulting in hot and cold spots in your home and making it harder to reach your desired indoor temperature.

Poor Indoor Air Quality

A dirty AC air filter allows dust, dander, and debris into your air duct system, reducing the quality of the air you breathe and potentially causing respiratory issues or even mold in your ducts. Changing your air filter regularly is especially important if anyone in your home suffers from asthma or respiratory allergies.

Furnace Failure

A clogged air filter can even cause damage to your furnace. The overworked blower may fail entirely, causing the whole HVAC system to fail, resulting in costly repairs or replacement.

Keep Your HVAC System Maintained

To prevent any of the problems mentioned above, it’s critical to check your air filter regularly. If your air conditioner has a reusable filter, clean it regularly and let it dry completely before placing it back in. If your HVAC system uses a disposable filter, replace it with one that is sized and designed specifically for your system. We recommend checking your air filter at least once a month, but advanced filters can last longer. Consult the manufacturer for a recommended replacement schedule. It is also essential not to let your air conditioner run without a filter to avoid potential catastrophic issues in the future.
