When to Replace Your Combi Boiler
How to know when to stop repairing and start fresh.
Combi boilers typically last 10–15 years with good maintenance. As they age, repairs become more frequent and efficiency drops. There's a point where continuing to repair an old unit costs more — in money, comfort and risk — than replacing it.
Here's how to weigh repair against replacement honestly.
Signs it's time to replace
- The boiler is over 12–15 years old
- Repairs are becoming frequent or expensive
- Efficiency has dropped and gas bills have risen
- Parts are hard to source for an older model
- Recurring safety concerns (flame colour, leaks)
- You want rebate-eligible efficiency and smart controls
The replacement upside
A modern 95% AFUE condensing combi cuts gas use, qualifies for rebates, runs quieter, and restores reliability and warranty coverage. We'll give you an honest repair-vs-replace comparison rather than pushing a sale.
This is not a DIY repair
Combi boilers are gas-fired appliances regulated under the BC Safety Standards Act. Opening the unit, touching the gas valve, or working on the flue without a valid BC gas-fitter licence is both unsafe and illegal. Diagnosing the fault is helpful — fixing it should always be left to a certified technician.
