Knowing when the Filter should be Replaced


Filters are important because they prevent pollutants from going through the HVAC system. This means they will be released into the air and you will be breathing them in. It will also make your furnace system less efficient because of extra wear and tear that it might have.

Dust is something that can affect the performance of your filter. Change the filter more often if you have more dirt and dust in your home. Dust can wear on the parts and components of the furnace when it operates. The more dust you have, the more often you should change the filter. You can also contact us and we can advise you on when it should be changed.

Changing the filter can depend what your home is like. If you have one pet, or several, it can determine it. Also if you or anyone in your home smokes. If you have more than one pet, then you will need to change the furnace filters more often than if you have none. The more animals you have, the more often you will have to change the filter. If you only have one pet then you can change that and change the filters every two, four and six months depending on the size of your filter.

Smoke can be a factor for when you need to change the air filter. Multiple smokers mean that one to two inch furnace filters should be changed monthly.

If you are not sure how often to change the filter, make sure to contact us. We can advise you on the correct schedule, and recommend what type of filter is right for your home.
