Appliances are expensive
There isn't any question about it
And your furnace may very well be the most expensive thing you have in your home, let alone appliance.
And yet time and time again we hear the question:
"how important is it really to change my filter" or "Do I actually need to have my furnace serviced?".
Simply put, the answers are "very", and "yes".
Think of your furnace like your car.
Your furnace, like your car, needs to be regularly maintained in order to keep it healthy.
Oil Change - Getting your oil changed is a necessary part of owning a car. Usually, you can neglect having it done for a little bit but you are doing so at the risk of your car. Changing your filters is like getting an oil change. If you neglect it, then you are risking the overall health of your furnace.
Tune up - Getting your vehicle a tuneup is necessary to keep everything in check. It is important to do this to make sure that all of your parts are in good order, otherwise there might be complications later on that are much more expensive to fix. This is the same with your furnace. If you catch things early on, then you are reducing the overall stress on every other part of your furnace which has to work harder to keep up. Not to mention that it is possible to lose your warranty if you choose not to have your furnace regularly maintained.
"How often should I change my furnace filter?"
A good rule of thumb to keep is changing your filters once every three months, or if you have pets, every month. The best practice would be to check them every month, as each home is different. If you do not change them then you are adding increased stress to your furnace just to have it function as it normally should.
"How often should I get my furnace serviced?"
We recommend to have your furnace serviced once a year before winter. This helps to ensure the longevity of your furnace and reduce overall costs when something breaks down.
