Your HVAC plays a significant role in indoor air quality. The air intake areas use filters to keep out pet fur, hair, and other contaminants that could clog the machines. Here is some insight into when to change the filters to keep your system in top shape.

How Often Should You Change the Filters?

If you have no pets, you can change the filters every three months or once a season. Homes with many visitors or large families should change them more frequently.

HVACSwapping the filter every month will prevent the filter from clogging, which can make the system fail and require immediate repairs. People who own furry pets should also change the filter monthly because of the increase in fur and dander.

Households with residents who have respiratory issues like COPD or asthma can maintain better air quality with monthly filter changes. Adding an air purifier to the home can also filter out tiny particles of air pollution and chemicals that may trigger symptoms and clog the HVAC filter faster.

What Are Some Signs the Filter Needs to Be Changed?

Install a new filter if you can’t remember the last time you changed it. Keep an eye on the HVAC vents, as dusty air may be a sign the filters are full of contaminants.

Hang a white sheet several inches in front of the vent for a few hours and see if the coloring changes. If it darkens, there’s too much dust in the system, and you need a new filter.

Air conditioners that give off hot air may indicate the filter is clogged, preventing fresh air from entering the system and causing it to overheat. Sudden increases in the electrical bill can also signify a clog that causes the HVAC to work harder to keep the home at a comfortable temperature.
