About London Metal Duct Supply Inc.

---

London Metal Duct Supply is one of the largest sheet metal ductwork manufacturing employers in southwestern and central Ontario. Family-owned and operated since 2016, our family-owned company has specialized exclusively in the production of HVAC ductwork and custom sheet metal fabrication.

Unlike competitors, we do not install ductwork or bid on HVAC construction projects. Our focus is to support contractors — not compete with them. By manufacturing ductwork and supplying materials directly to sheet metal and HVAC professionals, we help our clients complete projects with success.

Our team combines hands-on experience, modern equipment and dependable turnaround times to meet the demands of commercial, industrial and residential HVAC projects.

As a locally rooted company, we take pride in supporting our clients, our employees and our community through dependable service and long-term relationships.
