AC Mechanical provides full-scope mechanical construction and retrofit services for commercial, institutional, and industrial facilities across Ontario. We specialize in complex retrofit projects within occupied, phased, and mission-critical environments, where continuity of operations, safety, and precision execution are non-negotiable.
Our team works closely with owners, consulting engineers, and general contractors to deliver mechanical systems that are code-compliant, energy-efficient, and built for long-term performance. Whether supporting new construction or modernizing aging infrastructure, AC Mechanical brings the technical expertise and coordination required to manage risk and minimize disruption.
We have extensive experience executing retrofit work in facilities that remain operational throughout construction, including healthcare, education, manufacturing, and data-sensitive environments. Our approach emphasizes detailed planning, clear communication, and disciplined site execution to ensure seamless integration with existing systems.
Mechanical construction and retrofit capabilities include:
- Boiler plant retrofits and hydronic heating systems, including equipment replacement, piping reconfiguration, and control upgrades
- Chiller plant retrofits and HVAC piping systems designed for efficiency, redundancy, and future capacity
- Air handling unit (AHU) replacements, including structural coordination, rigging, and commissioning support
- Plumbing installations and repairs covering domestic water, sanitary, storm, and process systems
