Your furnace is one of the most important systems in your Saskatoon home—especially during our long, frigid winters. But like all appliances, furnaces don’t last forever. So, how long should a furnace last, and how do you know when it’s time for a replacement?
Average Furnace Lifespan
On average, a furnace will last 15 to 20 years with proper care and maintenance. However, the exact lifespan depends on several factors, including:
- Type of furnace: Gas furnaces typically last 15–20 years, while electric furnaces may last slightly longer.
- Maintenance history: Annual tune-ups extend furnace life significantly.
- Usage: Furnaces in colder climates like Saskatoon work harder, which can shorten their lifespan.
- Installation quality: A professionally installed furnace performs better and lasts longer.
Signs Your Furnace May Be Near the End
Even if your furnace hasn’t completely failed, there are clear warning signs that replacement may be on the horizon:
- Frequent repairs: Constant service calls add up and may cost more than a replacement.
- Rising energy bills: Older furnaces lose efficiency, leading to higher monthly heating costs.
- Uneven heating: Some rooms feel too hot while others remain cold.
- Strange noises: Banging, rattling, or humming may indicate failing parts.
- Visible rust or cracks: Signs of aging components that compromise safety.
- Age: If your furnace is over 15 years old, it’s wise to start planning for replacement.
The Benefits of Furnace Replacement
Replacing your furnace is a big investment, but it comes with important benefits:
- Improved energy efficiency—new models can reach 95%+ AFUE ratings
- Lower heating bills
- More consistent comfort throughout your home
- Enhanced safety with updated technology
- Fewer breakdowns and repair costs
Repair or Replace?
A general rule of thumb: If repair costs are 50% or more of the cost of a new furnace, replacement is usually the smarter choice. Investing in a modern, high-efficiency system can actually save money in the long run.
