Your HVAC system keeps your home comfortable, but without a filtration system in place, it would be stuck circulating dirty air. Neglecting air filters doesn’t just lower air quality—it can also have a range of adverse effects on your HVAC system. The guide below explains how the filtration system works and why you might need a visit from an HVAC contractor if you don’t change it often enough.

How an Air Filter Works

The air filter acts as a shield between the central air intake and the ductwork where heated or cooled air is distributed. As the system pulls in air, it’s also drawing in contaminants like pollen, dust, and pet dander. The filter, which is usually made of fiberglass surrounded by cardboard, allows the air to pass through while trapping small particles. However, if the filter isn’t changed often enough, it can have negative effects.

What Happens When You Don’t Change Air Filters Often Enough

A dirty filter is less efficient, which means that the air blowing out of your vents will be dirtier. This can be particularly difficult for family members who deal with allergies or respiratory issues.

A filter that’s deeply saturated with dirt will also limit air intake, which means less air reaching your ducts and rooms that are inadequately heated or cooled. In extreme cases, dirty filters can also increase the strain on your HVAC system as it struggles to pull enough air in. This results in both higher energy bills and increases the likelihood of a breakdown. Save yourself the call to an HVAC contractor and change the filter according to manufacturer guidelines.
