Every furnace has a lifespan, and sooner or later, homeowners face the question: Should you repair your current system or replace it entirely? The answer isn’t always straightforward—it depends on age, efficiency, repair history, and your long-term comfort goals.
If you’re in the Comox Valley and wondering which option makes the most sense for your home, here’s a practical breakdown.
1. How Long Do Gas Furnaces Last?
On average, a well-maintained gas furnace lasts 15–20 years. Coastal climates, such as the Comox Valley’s, can put extra wear on systems due to moisture and humidity, so maintenance plays a significant role in maximising lifespan. If your furnace is nearing or past that 20-year mark, replacement is usually the most cost-effective choice.
2. When Repair Makes Sense
Repairs are often the best choice if:
- Your furnace is under 10 years old
- Repairs are relatively minor (like replacing a thermostat or fan motor)
- Your energy bills haven’t spiked significantly
- Your home is still heating evenly and reliably
In these cases, a professional repair can extend the life of your furnace for years to come.
3. When Replacement Is the Smarter Option
Replacement usually makes more sense when:
- Your furnace is over 15 years old
- Energy bills keep climbing despite tune-ups
- Repairs cost more than one-third of the price of a new system
- Your furnace needs frequent service calls
- Your home isn’t staying as warm or consistent as it used to
A new high-efficiency furnace may seem like a larger upfront investment, but it can quickly pay off in energy savings and peace of mind.
4. The Cost-Benefit Balance
Think of it this way: if your furnace is old and inefficient, each repair is like putting a patch on a worn-out tire. It may hold for a while, but eventually, you’ll need a full replacement. Weigh the cost of repairs against the savings and reliability of a new unit to find your best option.
