Maintaining the filter on your air conditioning and heating equipment isn’t fun or glamorous. So why bother? Because a clean filter allows for proper air flow, and that makes the equipment run efficiently, saving you money. Also, a clean filter helps your system perform better, so your home environment will feel more comfortable.
And because a dirty filter restricts air flow and can make a heating unit overheat or an A/C unit freeze up, maintaining the filter helps you avoid a service call.
Filters come in various types, so take a look at your equipment. If you have a cleanable filter, note on your calendar when cleaning is due. Otherwise, buy an appropriate replacement filter to have on hand when you need it. Filters are inexpensive and should be changed or cleaned when they are visibly dirty. When you do change the filter, note the directional arrows on the side. Place the filter so that the arrows point in the direction of air flow.
