Furnaces have filters that filter out the impurities in the air from entering the furnace and spoiling any part of the equipment, mainly the fan and the heating coil. Furnace filters often come with additional features like humidity controllers and allergen filters etc. There are many particles in the air that are not good for our health also. Good furnace filters available at Chandler Air Conditioning and Heating purify the air in the room and hence are the best for home with small kids or people with respiratory disorders. They are capable of removing dust particles, pollens, allergens and even bacteria from the air inside the room.

Why Do I need to Change the Filter?

With time, filters become dirty and start hampering the air flow through them. This adds additional load on the furnace and shortens its life. Hence we need to change them from time to time to keep them clean and well functioning.

How Often Should I Change the Filter?

The frequency at which you need to change the filter depends on the type of filter your furnace uses and of course, the brand. This information can be available on the manual you get along with your equipment when you buy it. You can also find more details on the website of the brand your furnace belongs to.

If it is a disposable filter, the frequency would range from a month to three months while if it is a pleated filter might require replacement from within 3 months to a year.
