Commercial HVAC Systems in Multi-Unit Developments: What Goes Into a Proper Installation?

Commercial HVAC systems in multi-unit and mixed-use developments require careful planning, coordination, and execution. Unlike residential installations, commercial HVAC involves multiple system types operating together, including heat pumps, fan coils, ERVs, make-up air units, exhaust fans, and parkade ventilation systems.

A properly designed HVAC system begins with reviewing mechanical drawings and understanding airflow requirements, zoning, and equipment placement. Systems such as fan coils and heat pumps must be coordinated with ductwork, refrigeration piping, and control strategies to ensure efficient operation and occupant comfort. In many commercial projects, energy recovery ventilators are used to improve indoor air quality while reducing energy loss, especially in tightly sealed buildings.

Installation is only one part of the process. Commercial HVAC systems require commissioning, air balancing, and startup reports to confirm that airflow, temperatures, and system performance meet design intent. Without proper testing and verification, even a well-installed system may underperform. Working with experienced mechanical contractors ensures these steps are completed correctly and documented for inspections and handover.
