How Often Should You Change Your Air Filters?

February 28, 2012

Next to having seasonal furnace inspections, the most important thing you can do to keep your furnace in good shape all season long while maintaining good indoor air quality is make sure you change your filters regularly. As your furnace runs, it picks up lots of contaminants from the air and blows them through your ducts. That air passes through the filter, where the contaminants are trapped and only clean air gets through.

With all those contaminants passing through, it doesn’t take long for the filters to get clogged up. As the filters get filled more and more, air is going to have a much harder time pushing through it. This quickly results in decreased furnace efficiency and eventually can cause a complete breakdown, leaving you needing furnace repair in Cincinnati!

During the upcoming months, changing your furnace filters regularly is going to be extremely important in order to keep the air in your home safe and healthy. A lot of families have questions about the importance of changing their air filters regularly – questions we hope to answer here!

How often should you replace your air filters?

Since you’re going to be both using your HVAC system more and staying inside more, it’s important you at least inspect your air filters once a month and change them every three months. Remember: this is at minimum – you may need to change them as often as once a month.

Why do you need to change your filters so often?

Even though they seem simple, your air filters actually have a pretty major effect on not only your indoor air quality but also on the way your furnace operates! It’s important you keep on top of changing your air filters for a number of reasons.

Like we said above, your filters collect all sorts of dust, pet dander, pollen, etc. over the course of the season. It’s not long before they start to get clogged up, making it much more difficult for air to pass through. As a result, the blower has to work harder, which causes your energy bill to increase and eventually may cause the blower motor to overheat and burn out!

In addition, the reduced airflow means it will take longer to heat your home. After a while the airflow may get so stopped up that many rooms farther away from the HVAC system won’t get any air at all!

Changing your furnace filters regularly – at least every three months but preferably every month – is the best thing you can do to ensure proper furnace operation all winter long.
