Proudly Based in Petrolia, Ontario

All Systems Mechanical began in December 2018 as a numbered Ontario company. At the time, we hadn’t settled on a formal name—we knew it needed to reflect not only who we were, but everything we wanted the business to become.

We considered using our family name or drawing inspiration from one of Ontario’s beautiful Great Lakes. “Great Lakes Heating & Cooling” was one possibility, but it didn’t quite capture the full range of services and experience we brought to the table.

With more than 20 years of experience in HVAC and refrigeration, we had worked on an incredibly diverse range of equipment and systems. It often felt as though there wasn’t a system we couldn’t tackle—and that’s when the right name became clear:

All Systems Mechanical.

From there, we were off and running. The calls started coming in, and we approached every job with the same goal: solve the problem properly and make sure our customers are taken care of.

Since then, ASM has continued to grow while proudly providing professional HVAC, refrigeration, and mechanical solutions throughout Southwestern Ontario. We have travelled countless kilometres in every kind of weather to be there when our customers need us—and we wouldn’t have it any other way.
