Finding Your Air Conditioner/Furnace Filter

Funny enough, in some cases finding the filter can prove difficult. In each home that I’ve lived in it’s been an easy find. It was always just past the furnace and could be easily seen when looking straight the furnace. As we all know though, not every house is the same and not every environment is the same.

Filter locations are typically found somewhere around the return duct or blower compartment before the returned air can reach the air handler. Having it setup this way allows the filter to clean the air in your house before it enters into your HVAC system. The filter serves as a guard before the air is recirculated throughout your home.

Typically, filters can be found near the furnace, in the air conditioner itself, or in nearby walls and ceilings. When looking for the filter you should check to the sides, above, and even below your system. In some extreme cases there is a filter installed at each intake vent throughout the home. I haven’t seen these before, and while they would be a hassle to change every few months you can be assured that the ducts would be extremely clean since there would not be a chance for dust to be pulled in.


Your air conditioner and your furnace are some of the most expensive appliances in your home. It only makes sense to take care of them and to ensure that they last as long as they can. In today’s world a new AC and furnace could cost anywhere between six to twelve-thousand dollars.

By ensuring that your air conditioner filter is taken care of every few months you not only protect your system and investment but it also provides you clean air throughout your home. If you aren’t already, please take the time to clean or replace air filters not only for your health but also for your wallet!
