About us

Since 2007, SIMMCO Inc. has become one of Ontario's most trusted providers of commercial HVAC services.

What began with a focus on duct and HVAC cleaning has evolved into a comprehensive operation.

Today, we deliver HVAC cleaning, maintenance, and inspection services designed to keep your facility safe, efficient, and compliant.

All services are carried out by a fleet of fully equipped service vehicles and a team of certified technicians.

Why Clean Air Systems Matter

Over time, commercial HVAC systems and ductwork naturally accumulate contaminants like dust, mold, bacteria, and other airborne pollutants. These hidden buildups often go unnoticed—but their impact is real. Dirty coils and air ducts can compromise system performance, drive up energy costs, and lead to costly breakdowns.

Beyond mechanical strain, poor indoor air quality affects the people inside your building. Circulating air laced with pollen, mold, and debris can trigger health issues, reduce employee productivity, and lead to dissatisfaction among tenants, staff, and customers. In the long run, that means more complaints -and a direct hit to your bottom line.
