Gas Furnace WETT Inspection in Lisgar
Older 80% AFUE gas furnaces vent into a chimney (often shared with a hot-water tank) and the low-temperature exhaust condenses inside the flue — accelerating masonry decay. Modern 95%+ AFUE furnaces sidewall vent and orphan the chimney. In Lisgar, Mississauga, our WETT inspection visit takes 45–90 minutes and includes a written photo report.
