Here’s a great tip to keep your furnace in working order: check your furnace filter. A clean filter prevents dust and other debris from being sucked in by the blower fan. Just keep in mind, a severe blockage risks damage to your furnace.
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 see light through the filter with little to no signs of dust, it is still working. On the other hand, if it’s clouded out with dust you’ll need to replace it soon.
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. There are some washable reusable filters out there, but for the most part disposable filters are just as good, even if you need to buy new ones every once in a while.
To replace a filter, start by turning off your furnace. Once the filter has been removed and you’ve fitted the new one, 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.
