Tool · Repair or replace
Repair or replace? A screening band, not a verdict
Four inputs — furnace age, the confirmed repair quote, the certified AFUE and annual gas use — produce a recommendation band. A real decision needs the diagnosis and the written replacement scope; this tool frames the comparison.
What the tool uses
- The typical installed replacement range published by BC Wide: $4,500–$8,500 for a residential high-efficiency furnace in Metro Vancouver depending on size, brand and venting (checked 2026-09-07).
- The 95% AFUE floor for new furnaces under federal regulation, which sets the efficiency comparison.
- Typical furnace service life and the repair-frequency logic from this site's repair-versus-replacement guide.
Data sources: BC Wide furnace-installation guidance page (checked 2026-09-07), Natural Resources Canada gas-furnace regulations, GasFurnace.ca guide repair-vs-replacement. This tool never invents a quote, a diagnosis or a heat-exchanger finding — those come from the actual visits.
Safety first, always
A gas smell or CO alarm is not a repair-versus-replacement question: leave the building and call FortisBC at 1-800-663-9911 or 911, then BC Wide.
