How To Change a Furnace Filter
Periodically changing your furnace filter is an important part of HVAC maintenance. Thankfully, this is a relatively simple task that anyone can complete.
Changing Your Furnace Filter Doesn’t Have to Be Difficult
The first thing you want to do is simply to turn your furnace “off.” In addition, you can disconnect the power so that there is no power going to the furnace as well. This step is optional.
After you do that, try to identify where your furnace filter is. You’ll do this by most likely removing the cover on the front side of the furnace. You can remove the furnace’s cover by pulling up. If that doesn’t work, you can look at your furnace’s manual. This will help you locate the furnace filter.
After you locate the filter, you’ll want to confirm if your furnace filter even needs to be replaced. If your filter is plastic-framed, you don’t need to replace it. Just rinse it off in your sink or tub.
However, if it does need to be replaced, you’ll want to identify the size of your furnace filter next. This is usually pretty simple. Just look carefully for the size listed on the filter itself. Alternatively, you can measure the filter with a tape measure.
Removing the Old Filter and Installing the New Replacement
Remove the old filter from the furnace. When you remove it, make sure you check which direction the airflow arrow is pointing on the filter. You have to install your new filter with its airflow arrow pointing in the same direction; the arrows should be pointing toward the furnace.
Now, simply insert your new air filter into your furnace with its airflow arrows pointing toward the unit. After you turn on your furnace, you’ll be done.
