A Comprehensive Guide To Furnace Filters

Posted on

You need to leave most HVAC jobs up to professionals because they are too complicated. But, servicing and changing your air filters is one piece of HVAC maintenance that you can handle yourself. There are a few things you need to know when it comes to shopping for and replacing your furnace filter. This article is a comprehensive guide to furnace filters.

Where is the Filter?

The filter is usually very easy to find. On some furnaces, it is inside the actual cabinet, but on others, it is on the outside. If your filter is on the inside, you will probably be able to immediately see it once you open up the furnace access panel. If your filter is on the outside of the furnace, you can find it easily because it is located near the air ducts. That is, there is usually a small slot or compartment where the air duct meets the side or back wall of the furnace. In most cases, the filter can be pulled out without any tools. There may be a small door that you need to flip open in order to pull out the filter.

Make Sure You Have the Right Sized Filter

Buying your new filter might be a little tricky if you don't know the exact measurements that you need. Some filters are organized by model number, but most are just sold by size. So, you shouldn't go to the store knowing the exact size (including thickness) of your filter. Some people even bring their old filter into the store with them to be certain it is the right size. Most filters will cost less than $20 and they can be found at home improvement stores and even some larger grocery stores.

The fact that filters are so cheap and easy to change should encourage you to replace them at least once a year. For the most efficiency, you should consider changing your filter about twice a year. Change it once at the end of winter, and once at the end of summer. This way you will have a brand new filter every year when you start to use your furnace or air conditioner.

As you can see, filter replacement is easy, but you need to know how to do it and what to buy. You can definitely increase the efficiency of your system, improve air quality in your home, and lengthen the overall lifespan of your appliances if you change your filter regularly.
