How Dirty Filters Affect ACs

During a seasonal tune-up, your HVAC contractor will replace or check your system’s air filter. Additionally, you should be replacing the air filter every 30 days for a 1” thick filter and every 90 days for a 4” thick media filter. When you keep your air filter clean, you’ll be helping your heating and cooling system run more efficiently. A dirty air filter can inhibit the operation of your system in several different ways.

Increases Your Need for Air Conditioning Maintenance in Indianapolis, IN

When you operate your HVAC system with a dirty air filter, the unit won’t be able to clean debris and contaminants from the air. This setup results in dirty air circulating through the system. Dust, debris, and other pollutants will cling to your evaporator coils and other components. A dirtier system will break down more frequently.

Your HVAC contractor will also have more work to do when they provide you with seasonal air conditioning maintenance in Indianapolis, IN. They will spend more time cleaning your coils and repairing damage caused by the buildup of debris. You can save on your HVAC service costs by keeping your air filter clean.

Reduces Airflow Through Your Ducts

Since less air passes through a dirty or clogged air filter, there will be a reduction in the amount of air that’s sent to your ducts. It will take longer for the reduced airflow to properly cool your home, forcing your HVAC system to run in longer cycles. 

Your system may not be able to reach your desired temperature at all if the airflow is significantly reduced.

Pay attention to how long and how frequently your AC unit runs through a cycle. If you notice the unit is running more frequently, check your air filter. If cleaning or replacing the filter doesn’t fix the problem, you may need to call your HVAC contractor.

Shortens the Lifetime of Your HVAC System

As previously mentioned, failing to clean your air filter will increase your need for air conditioning maintenance in Indianapolis, IN. Over time, a habit of operating your system with a dirty air filter can cause long-term damage to the system. 

Wear and tear damage will occur at a faster rate when the system consistently runs through cycles more frequently. Even though the system should last up to 25 years, failing to keep the filter clean can cut its lifetime in half.
