Rooftop Commercial HVAC Systems Installation

Rooftop commercial HVAC units provide heating, cooling and ventilation for offices, retail spaces, restaurants and light industrial buildings, all from compact units installed on the roof.
They free up floor space inside, simplify service access and are designed for continuous operation in demanding commercial environments. AirTek helps businesses choose, install and maintain rooftop commercial HVAC systems that deliver reliable comfort for staff and customers while controlling energy costs.

Rebates and Incentives for Efficient Commercial HVAC in Quebec

If you are planning a commercial HVAC installation or replacement in Quebec, there may be financial incentives available for high‑efficiency equipment, particularly heat pump–based systems that provide both heating and cooling. Provincial and federal programs are primarily aimed at improving energy performance and reducing greenhouse gas emissions, and eligibility depends on building type, existing equipment, and the selected technology. Our team helps you identify which incentives may apply to your project and coordinates with partners when needed so you can take full advantage of available support.

Our Rooftop Commercial HVAC Installation and Replacement Process

Site Assessment and System Design

We start with a site visit to review your building layout, roof structure, existing ductwork, electrical service, and ventilation needs. We then size and select rooftop units based on occupancy, internal gains, zoning, and outdoor design conditions to maintain comfort and airflow across all occupied areas.

Rooftop HVAC Delivery and Coordination

Our team coordinates crane lifts, roof access, safety measures, and any temporary shutdowns so work is completed with minimal disruption to your operations. We also plan duct connections, curb adapters, condensate routing, gas and electrical connections, and controls integration in advance so installation day runs smoothly.

Rooftop Unit Installation, Start‑Up and Commissioning

We remove existing rooftop units when required, install new curbs or adapters, set the new units in place, and complete all duct, gas, electrical, and condensate connections according to code. Each system is then tested, commissioned, and balanced, and we verify thermostat and building management system integration before turning the system over to your team.

High‑efficiency rooftop units are designed for demanding commercial conditions, delivering reliable heating, cooling, and ventilation while helping control operating costs across changing Quebec seasons.
