In addition to working with an HVAC contractor to maintain your system, it’s important to swap out the air filter regularly. This will protect your air quality and reduce your energy bills. Here’s how to change it and when to do so. 

Your Guide to Changing HVAC Filters

Why You Need to Change It

HVAC filters remove dirt, dust, pollen, and harmful microbes from the air before it gets conditioned and redistributed through the vents of your home. When filters become saturated with particles and allergens, the quality of your indoor air will diminish, resulting in unpleasant odors and upper respiratory illnesses.

Dirty filters also cause your heating and cooling system to work harder and use more power to pull air through the intake vent. As a result, your system may expend excessive energy, break down, or reach the end of its life span prematurely, which is why you should replace the filter.

Signs of Needing a New Filter

As a general rule, HVAC contractors suggest replacing the filter once per month. However, if you notice musty odors, increased energy bills, or weak air flow from your vents, change the filter more frequently. Additionally, if you smoke in your home or have indoor pets, swap out your filter twice a month to maximize indoor air quality and promote energy-efficiency. 

How to Change It

To change your HVAC filter, locate the intake vent, and unscrew the hardware. Behind the metal grates, you’ll notice a filter that will have its dimensions printed along the edges. Remove and replace it with a clean one of the same dimensions before closing the vent and re-fastening the hardware.
