About Us
A GTA HVAC Company Built on Careful Work
Thermetix Mechanical Inc. provides reliable heating and cooling solutions with a focus on quality workmanship, dependable service and practical recommendations.
Thermetix Mechanical Inc. is a heating and cooling company based on Brunel Rd in Mississauga. We install, repair, maintain and troubleshoot HVAC equipment for homes, condominiums and commercial spaces across Peel Region and the wider Greater Toronto Area.
Our approach is straightforward: diagnose the system properly, explain what we found in plain language, and recommend the option that makes practical sense for the equipment in front of us. That applies whether the job is a seasonal maintenance visit, a no-heat call in February or a full furnace and air conditioner replacement.
We work across residential, condo and commercial systems — furnaces, air conditioners, heat pumps, water heaters, condo heat pumps and fan coils, commercial rooftop and make-up air units, high-rise boilers and ductwork. Condo HVAC in particular is a focus because in-suite systems require familiarity with how they are configured and serviced.
For questions about a specific system or a quote, contact Sampath Geewandara at 647-227-1214.
