We start by understanding the issue, inspecting the system, and outlining the best path forward—so you can make an informed decision.

Custom installation & quality repairs
Whether it’s a retrofit, a new build, or a complex refrigeration issue, we install and repair with long-term performance in mind.

Our story
Local service, built for Ottawa’s seasons.
Cosenzo Mechanical was built around a simple idea: do the job right, communicate clearly, and treat every customer like a long-term relationship—not a one-time ticket.
Based in Ottawa, we support homeowners, property managers, and businesses across the region with HVAC and refrigeration service that’s practical, dependable, and tailored to the space. We know how hard our climate can be on equipment, so we focus on correct sizing, clean installs, and repairs that address root causes—not just symptoms.
We believe great service is equal parts craftsmanship and follow-through—show up prepared, work clean, and stand behind what you install.
Cosenzo Mechanical
