Clogged, old, or broken filters can cause a lot of problems for your furnace. By extension, they can cause a lot of problems for your in-home comfort. The good news is that dealing with filters is one of the few things that you can do without the need for professional help:
Problems Caused by a Dirty Air Filter
Quite a few issues can alert you to a possible problem with your filter. As a filter does its job, it will accumulate a lot of dirt and debris. This is normal but your filters cannot continue to this indefinitely.
As the filter starts to clog, air will have a harder time passing through it. This alone can lead to many problems that will countermand the integrity of your furnace as well as cause you home heating problems.
For example, a clogged filter can lead to,
As one of the most common causes of furnace problems, you should probably get in the habit of checking your filters as soon as theirs a problem. While filters represent the most common cause of problems, clogged filters represent the most common problem affecting filters.
Checking and Changing Your Air Filter
Your owner's manual will show you where to look for your furnace's filter. There's no single place to check as furnaces vary by brand, type, design, and other factors. You can likely find the filter in a slot behind the service panel. It's usually right by the furnace's blower fan.
Once you find it, take a look. A clogged filter is obvious. Sometimes there's still life left in a filter. You can hold it up under light to check. If light still shines through it, there's still some life left in it.
What isn't so obvious is what kind of filter you're dealing with. Knowing that can help you figure out what kind of filter to replace it with. Once again, this is something you need to glean from your owner's manual or the manufacturer's website.
Most generic filters are fiberglass or paper. These are disposable and you should replace them as often as the manufacturer recommends. You should at least check them one a month. Reusable filters have more of a dry foam look to them and you can wash those off with a hose then dry them.
Getting Help with Your Air Filter from a Professional
Since each furnace is different and different manufacturers have differing filter requirements, you will have to do some research on your own. Alternatively, you can ask a professional furnace repair and maintenance service help you out. A professional can recommend the right type of filter for you and show you how and when to change or clean it.
