Commercial HVAC

Commercial HVAC

In commercial settings, a malfunctioning HVAC system can damage assets, spread illnesses to building occupants (resulting in legal action), and hurt your employees’ productivity. At One Alliance HVAC, we get the job done while minimizing disturbance of day-to-day operations.

Commercial HVAC Services in the GTA

A healthy HVAC system translates to a healthy business environment!
Commercial buildings with up-to-date, well-maintained HVAC systems:

  • Protect company assets from computers to inventory
  • Facilitate a safe, healthy working environment
  • Create a positive impression on clients and customers
  • Help the company’s bottom line by preventing unexpected repairs and keeping energy costs down!

At One Alliance HVAC, we understand that commercial properties face special challenges. For example, commercial HVAC systems need to be installed away from high-traffic parts of the building, often on rooftops. Doing so reduces noise, increases occupants’ working space, allows continuation of business activity during HVAC repairs, and keeps the machinery safe from vandals.


We provide a full set of services for commercial HVAC systems:

  • Boiler sales, installation, maintenance and repair
  • Furnace sales, installation, maintenance and repair
  • Central air conditioner sales, installation, maintenance and repair
  • Ductless air conditioner sales, installation, maintenance and repair
  • Ductwork design, fabrication, maintenance and repair
  • 24/7 Emergency repair services

We fix and service all brands. Should the need arise, One Alliance HVAC technicians can work with you to design and install an HVAC system from scratch- one that tailors to your buildings’ unique needs.
