When It is Necessary to Replace Your Furnace?

If your furnace isn't functioning properly, you might wonder whether to repair or replace it. Deciding fast is crucial, especially if it breaks down in the middle of winter. To help you decide, here are some points to consider:


  • First, consider the age of your furnace. A typical furnace should last 15-25 years but could require repair at any time prior to the end of its lifecycle.  In this case, the repair cost should not exceed 50% of the cost of a new furnace. If it does, it's best to replace your furnace.

  • Next, think about your energy bills. If your furnace is causing an increase in your energy bills, and it's not due to extreme weather conditions, then it might be time to replace it. Similarly, if you're calling for service repairs frequently, it's a sign that your furnace needs replacement.

  • Another sign to look out for is uneven heating in different parts of your home. If you're experiencing this issue, it could mean that your ductwork isn't designed properly, which may also indicate the need for a furnace that will work better with the ducting it has available.


It's important to note that regular maintenance and servicing can help extend the lifespan of your furnace. However, if you notice any of the above signs, it might be time to consider replacing your furnace. Call us today to learn more about our furnace replacement services in Okotoks or read our FAQs.
