For Chilliwack homeowners with a furnace past its fifteenth year, the right call usually comes down to the specific failure and its cost, not the calendar alone.

Quick answer
There's no fixed age at which a Chilliwack furnace must be replaced, but once a unit passes roughly 15 years, every repair decision should factor in what else might be close behind it. CANRO looks at the actual failed component, how the furnace has been maintained, and the realistic cost of the repair, then gives you a direct answer on whether repairing or planning replacement is the more sensible move.

Furnaces typically serve somewhere in the 15-to-20-year range, sometimes longer, sometimes shorter, depending heavily on how the unit was maintained and how hard it's been run. Past that first milestone, the question stops being just 'can this be fixed' and starts including 'is this the best use of money on a unit this far into its service life.'
This is especially relevant across Chilliwack's older neighbourhoods, where original equipment from decades-old builds is now well beyond that threshold, alongside newer subdivisions where furnaces are still comfortably within their prime years.
A single item from this list isn't cause for alarm on its own. Several appearing together on a furnace already past 15 years is the pattern that usually shifts the conversation toward replacement.
| Repair scenario | Typical recommendation |
|---|---|
| Small part, furnace otherwise trouble-free, under 15 years old | Repair, straightforward call |
| Heat exchanger or control board failure past 15 years | Usually replace, given the cost weighed against remaining service life |
| Second or third repair call within one winter | Consider replacement, since recurring failures suggest broader wear |
| Inexpensive fix on an otherwise well-kept older unit | Repair now, start planning for replacement |
We'll never push a replacement on a furnace that's fundamentally sound purely because of its age. When a major component fails on a unit already well past 15 years, though, we'll say so directly and walk you through why.
Chilliwack Proper and Sardis have plenty of homes built through the 1970s and 80s still running original or first-generation replacement furnaces, often in crawlspace installations that make component access slower than in a newer walk-in mechanical room. Rural properties toward Greendale and Rosedale can add another wrinkle, with longer gas line runs and less frequent access for routine maintenance, both of which can shorten the practical service life of an aging unit.
We inspect the furnace itself, check the burner and heat exchanger condition, ask about the maintenance and repair history you're aware of, and review the specific issue prompting the visit. From there you'll get a clear, direct recommendation, plus a general idea of what replacement would involve if that turns out to be the better path, so you can plan on your own schedule.
Safety note
A yellow or unsteady flame, soot buildup, or any gas smell around the furnace needs prompt attention from a Technical Safety BC licensed gas fitter, since these can point to incomplete combustion and carbon monoxide risk. If you smell gas, leave the home and call FortisBC at 1-800-663-9911 from outside.
Most commonly somewhere in the 15-to-20-year range, though maintenance history and how hard the unit has been run both affect that a great deal.
Not necessarily. Age alone isn't a reason to replace a furnace still running reliably with only occasional minor repairs.
Heat exchangers and control boards tend to be the more expensive failures, and on a furnace already well past 15 years, that's often the point where replacement makes more practical sense than repair.
Not inherently, but less frequent access for routine maintenance on some rural or acreage properties can allow small issues to go unnoticed longer, which can shorten practical service life.
No. If your furnace can be reasonably repaired, that's what we'll recommend, with an honest explanation either way.
The data plate on the unit itself usually has a manufacture date, or you can check any home inspection report from when you purchased the property.
