How to Extend the Life of my Furnace?

Updated: 3 days ago

No one wants their furnace to suddenly stop working when the temperatures drop overnight–no one wants to have to buy a new furnace either, especially when their current one isn’t even a teenager! So, what are some ways to help extend the life of your furnace?

Here we will outline some of our best tips to keep your furnace running smoothly and for longer so that your wallet can stay safe this holiday season, and so can your furnace!


Seasonal maintenance. Much like your air conditioner, your furnace also needs a tune-up twice a year, but even more importantly, at least before the cold season hits. Regularly scheduled seasonal furnace maintenance ensures that your heating system is running efficiently throughout every season of the year. The more you know about what goes on during these inspections, the better prepared you are to keep your family comfortable at home throughout each season.

Keep the air filters clean. Avoiding the excessive build-up of dirt, dust, and other debris is key to helping your furnace stay nice and healthy. As filters become overly saturated, they can easily break and let pollutants penetrate the system, which can cause significant damage if it goes unchecked. While the filters should be changed every once to six months, if you know you have a particularly dust-prone home or have pets, it’s wise to change all air filters about every 3 months to avoid unnecessary damage to your furnace.

Don’t put off repairs! Don’t worry–we’ve all done it. However, we all know that it’s always better to get repairs out of the way as soon as we know so that the situation doesn’t turn into something direr. During maintenance calls, if your technician notices that something needs to be fixed, it’s wise to schedule the repair immediately. If not, you can risk having an unusable heater, or worse, allowing the problem to snowball into something way worse and more costly than the original problem.

Keep your temperature steady. Find a temperature that is comfortable for you and leave it be. Constantly changing the temperature throughout the day causes the unit to work much harder than it would if the thermostat is kept at a steady temperature. When you have a favorite temperature and keep it there as a habit, you can really reduce the wear and tear on your furnace.

Clean and seal the ductwork. Ducts are what bring you your warm air on those frigid days. However, unsealed or unkempt ductwork can leach quite a bit of heat from the air that runs through them. Similarly to unsealed ductwork, dirty ductwork is also guilty of leaching heat from the air as it runs through the ducts–dust and dirt accumulated within the ductwork can cause significant obstructions over time, which makes your furnace work harder to push out hot air and maintain the set temperature. In fact, we recommend that ductwork be cleaned once every 3 to 5 years.

Run your ceiling fans clockwise. Did you know that ceiling fans could even do that? Well–they can! When fans are on the counterclockwise mode, it actually lifts air up instead of pushing it down, which can help distribute heat throughout a room in a very efficient way, thus bringing the temperature of the room up to the set temperature on the thermostat, which lets your furnace work a little less.

The bottom line

The lifespan of a furnace is dependent on how well it has been maintained and the quality of the installation. Most furnaces last between 15 to 20 years, but some can last up to 25, or even 30 years if they a
