Since we’re nearing the middle of December I wanted to post a quick reminder to change or clean those dirty furnace filters. Even if you keep an immaculate home, the filter in your furnace will clog up fairly quickly. If you don’t believe me, go take a look inside your vacuum bag. The same dust and debris that you see in there ends up in the filter.
When the filter is dirty, your furnace has to work much harder to heat your home. The reason for this is that a dirty filter will block the air from flowing into the blower and through your vents. This will make the fan have to work much harder. The blower fan will also have to run longer because less hot air will come out of your heating vents. Since less hot air is coming out of the vents, your furnace will stay running for longer durations because it will take longer for your home to heat up to the temperature that will allow your thermostat to shut everything off.
This is a very simple job that can be done in less than five minutes. I’ve included a short video below that will show you just how easy this job is.
Furnace filters are quite inexpensive to purchase and they are really easy to change but they are often neglected by many people. They’re kind of one of those “out of sight, out of mind” things. Since we don’t see them everyday, it’s easy to forget to change them.
How Often Should Furnace Filters Be Changed?
It’s recommended to change a furnace filter every 3 months but my advice is to inspect them at least once a month. If the filter is really dirty after only a month of use, you need to change it more often. There are a lot of factors that can determine how frequently a filter should be changed.
Here are just a few questions to ask yourself. If you answer yes to these questions, your filter may need to be replaced or cleaned more often than once every 90 days.
- Do you have pets?
- Is the furnace located in a high traffic area?
- Is your furnace located in a dusty environment like a garage or basement?
Do Your Furnace a Favor and Have It Serviced by a Professional
If you’ve neglected your furnace filter, you really should have a professional give the heating unit a good cleaning. You wouldn’t believe how much dirt and grime can build up inside of a furnace. Having it cleaned out properly could not only reduce your energy bills but it will probably help your furnace last longer.
As a matter of fact, you should probably have your furnace serviced and maintained by a qualified professional on a regular basis to keep it running at top efficiency.
