Air filters capture debris and contaminants that circulate in your residential HVAC, and they should be replaced at least every three months to keep the system working. Here are a few compelling reasons to change your filters regularly.

Why You Need to Change Your HVAC Air Filters

1. Reduce System Stress

The HVAC system blower has to work much harder to push air through a clogged filter, which puts stress on the motor. This problem cuts into the lifespan of your HVAC system. You may require repairs more frequently or experience a full breakdown.

Open the vents in your walls and ceiling that cover the entrance to your ducts. If the filter is dirty, remove it and place a new one in.

2. Lower Utility Bills

A system that has to overwork will waste more energy, raising monthly energy bills. Mounting repairs also get costly. Replacing dirty filters can lower residential HVAC energy consumption by 5–15%.

Plus, when you waste energy, power plants have to produce more electricity, which generates harmful carbon dioxide and damages the environment. 

3. Maintain Good Air Quality

The AC blower will push contaminants through clogged filters into your home, polluting the air supply. Family members with asthma and respiratory conditions may have trouble breathing, while those allergic to pet dander, mold spores, and other pollutants can become ill.

When choosing an air filter, start by looking at the pleats. These folds capture particles, so the more pleats a filter has, the more efficient it is. Also, look for reusable options that you can wash rather than replace. HEPA filters are recommended for family members with respiratory conditions or in homes with multiple pets because they capture 99.97% of contaminants.
