Furnace Repair vs Replacement: How to Decide

Text on a dark background reads "Furnace repair vs replacement: how to decide," guiding your furnace decision, next to a beige furnace unit on the right side of the image.

Every winter I encounter many homeowners who call us for furnace repair and often ask us if it’s worth repairing the furnace or spending more on a replacement.

In general, if your furnace is less than 10 years old, and the repair is minor, fixing it is usually the most economical choice. This is because the furnace is relatively new, and if it was installed correctly by a licensed technician, it should still be under the manufacturer’s warranty.

If your furnace is more than 10-15 years old, has frequent breakdowns, or has a major issue such as a cracked heat exchanger, a replacement furnace is usually the smarter investment, especially if rebates happen to be available at the time.

Why Replace My Furnace?

Energy Efficiency and Utility Bills

By law, all new furnaces on the market are high-efficiency furnaces with an AFUE rating of 90% or higher. This means that for every $1 spent on heating, 90% of that money is converted into heat. Old furnaces can have AFUE ratings as long as 60% or lower, meaning 40% of your utility bill to heat your home is wasted. A new furnace can save you money on your utility bills.

Rebates and Financing Options

Homeowners in Vancouver and across Metro Vancouver, including Burnaby, Richmond, Surrey, and the North Shore, can take advantage of several programs that make furnace and heat pump upgrades more affordable. FortisBC furnace rebates and FortisBC heat pump rebates can provide savings of up to $3,000, while BC Hydro rebates help lower the cost of installing ducted or ductless heat pumps.

Parts Availability

Unfortunately, as a furnace ages, parts availability starts becoming an issue. Parts may no longer be available to purchase or are special order only. This means you may be stuck waiting for parts for several weeks in the dead of winter. 

Warranty and Long-Term Reliability

A new furnace typically comes with a manufacturer’s warranty that can cover major components for 10 years or more, providing peace of mind and protection against costly repairs. Beyond the warranty, modern furnaces are built with improved technology and higher efficiency standards, reducing the risk of frequent breakdowns and ensuring consistent performance over the long term.

Comfort and Indoor Air Quality

Believe it or not, furnace and heat pump technologies have come a long way since the 80’s. Furnaces are now more efficient, quieter, and smarter than ever with smart thermostat and Google Home integration. This includes UV lights and IAQ filters which all help improve the overall air quality inside your home, important for those who are sensitive to dust and allergens in the air.
