A lot of the time, people forget entirely about their furnace filters. More often than not, people will only change their furnace filters when a technician comes to service their unit. Sometimes, these visits can be years apart! A clean filter prevents dust and other debris from being sucked in by the blower fan, but if it’s severely blocked you are at risk to damage your furnace. So, don’t forget to change your furnace filter!

A lot of furnace repairs come from a result of poor filter maintenance. Replacing your furnace filter only takes a couple of minutes to do, and it can save you a lot of money on significant repairs later on down the road.

Your furnace filter is designed to remove dust particles and other allergens from the air while your blower is on. After a few months, these filters can become quite dirty and should be replaced. Failure to do so could result in a hi-limit failure or unwanted stress which will ultimately hinder your furnace’s lifespan.

Most furnace filters are disposable but there are some reusable filters that can be washed and reinserted. If you need help finding replacement filters, let us know the size you are using (we can help you if you aren’t sure), and we can provide you with quality replacement options.

Typically, a furnace filter will need replacing every few months. This does depend on a few factors, so it’s best to check it every month or so to be safe. If you can still see light through the filter and little to no signs of dust in the filter, it is still working. On the other hand, if it’s clouded out with dust you’ll need to replace it sooner rather than later.

Furnace filters are readily available in many stores and can be bought in bulk, so it’s always a good idea to have a few extra ones stored somewhere in your home.

To replace a filter, start by turning off your furnace. Once the filter has been removed and you’ve fitted the new one, take a moment to ensure the flow arrow is placed properly. After you are confident that the filter is installed properly, turn the furnace back on. Finally, take a moment to ensure that everything is flowing well.
