Why It’s Important to Change the Air Filters



Air filters trap dirt and other particles before they enter the ductwork of a central AC unit. In a pet-free, smoke-free household, the filter should be replaced every three months. Many homeowners find this easy to do themselves while others rely on an HVAC company to do it as a part of preventative maintenance. Those who neglect the filter may want to consider the following points.

Dirty Filters Can Raise Your Energy Bills

When the filters get clogged with dirt, they will obstruct air circulation. As a result, the AC unit will have to work harder to cool the home, and this burden will be felt by homeowners as their electricity bills go up.

The Link to AC Breakdowns

These clogs will also wear out certain components sooner, including the blower unit, which is responsible for circulating the air. The compressor may also overheat. AC breakdowns are costly and may leave homeowners without cool air for several days.

When covered with dirt that passes through the filters, the compressor coils will render the refrigerant inside them unable to absorb any more heat (since the dirt provides extra heat). The result of this is that the AC will blow out lukewarm air. These are just some of the serious issues that old filters can be linked to.

The Connection With Bad Indoor Air

Filters can only trap so many particles, beyond which the pollutants that are in the home will circulate freely. Particles in the home can include dander, pet hair and germs while those that come from outside include pollen and smoke. This impacts indoor air quality and worsens allergies. Restricted airflow slows circulation, which means that particles will tend to settle in the vents, too, making a more extensive cleaning necessary.
