Weil-McLain has heated North American homes for over a century. We service their cast-iron classics and modern condensing boilers alike—repairing controls, replacing worn components, and upgrading aging units to high-efficiency models when it makes sense.

Weil-McLain has manufactured cast-iron and steel boilers in North America since 1881, and that heritage shows in how their equipment handles the demands of a Lower Mainland home. Metro Vancouver heating is characterized by long, damp shoulder seasons rather than the deep freezes common further inland, which means a boiler runs at partial load for most of its hours. Weil-McLain's condensing gas boilers — including the ECO Tec and Ultra series — modulate their firing rate to match this real-world demand, keeping efficiency high across the full heating season rather than only at peak output. For older Vancouver homes with cast-iron radiators or radiant baseboards, Weil-McLain's GV90+ and cast-iron sections are also a natural retrofit because they operate comfortably at lower water temperatures without stripping the system.
Our boiler services team carries Weil-McLain parts and maintains factory-trained familiarity with their full residential line. When CANRO installs a Weil-McLain boiler in Metro Vancouver, the work includes a Technical Safety BC permit, proper primary-secondary piping where required, condensate neutralization (mandatory for condensing models under BC code), and commissioning to the manufacturer's start-up checklist — all of which are conditions of the Weil-McLain limited warranty.
After years of servicing Weil-McLain equipment across Metro Vancouver, CANRO technicians recognize several recurring fault patterns that homeowners often describe as the boiler locking out, losing heat to part of the house, or running but not producing hot water. Diagnosing these correctly the first time requires reading the specific fault codes on the boiler's control board and checking the system — not just replacing parts.
If your Weil-McLain boiler is displaying a fault code, losing pressure, or heating unevenly, our Red Seal gas technicians carry the diagnostic tools and common Weil-McLain spare parts to resolve most issues same-day. Reach us at (604) 359-1081 or through our contact page to book a service call.
