How Often Should I Change the Filters in my HVAC System?

Picture
Changing the filters in your HVAC unit is an important part of maintaining it, keeping it running efficiently, and avoiding damage to your systems. But how often do you really need to change them? There’s no one answer, but there are some guidelines you can follow.
How often you need to change your filters is totally dependent on a wide range of variables. In order to decide the frequency that’s right for your unit, you’ll need to consider your habits and ask yourself these questions;

How often do you run your HVAC unit?
If it is always in use, you’ll likely need to replace your filter more often than if you only run the unit on occasion.

Do you have pets?
The fur and dander from your pets adds to the dirt and dust already being filtered by your system. If you have pets you’ll need to change your filters more frequently. This is especially true if you have multiple animals living in your home.

What are your cleaning habits?
If your vacuum doesn’t have a quality filter it’s likely spitting dirt and dust into the air which will then be filtered by your HVAC unit. The same is true if you don’t use a dusting method that traps and disposes of the dust as opposed to simply kicking it up into the air where it will resettle or be filtered by your system.

Does anyone in your home have allergies?
If so, it’s likely that they’re much more sensitive to dust, dirt, and dander than the average individual. In this case you would need to change your filter more frequently as well as choosing a higher quality filter that will remove more of these elements from the air.

If you tend to purchase lower end filters for your HVAC system, you’ll likely need to replace them more often. Avoid getting too strong of a filter though as this can actually make your unit run less efficiently. Shoot for something middle of the road that will do a good job of filtering the air in your home without putting too much stress on the system.Then check your filter occasionally until you’ve figured out the right length of time for your particular needs. If the filter looks dirty, it should probably be changed.

By changing the filters as part of your HVAC unit’s regular maintenance, you’ll ensure that your home has clean air and that you aren’t putting unnecessary strain on your unit.
