Commercial HVAC Installation Services
We specialize in HVAC installation for commercial clients and property managers across Greater Montreal. We work exclusively B2B — no service to individual homeowners or renters, no service contracts — just expert installation of rooftop units and ventilation systems.
Our focused approach means every project benefits from dedicated expertise. Unlike HVAC companies that divide their attention between B2C service, commercial, and service contracts, we concentrate all our resources on B2B installation. This specialization translates to more efficient execution, deeper knowledge of commercial equipment, and thorough understanding of commercial building requirements.
Our Installation Expertise
Rooftop Unit Installation
Our core specialty involves installing, replacing, and upgrading commercial rooftop HVAC units for buildings of all sizes. Rooftop units, or RTUs, represent the most common HVAC solution for commercial buildings in Quebec. They provide heating and cooling in a single unit installed on the roof, freeing up valuable interior floor space.
We manage the complete installation including crane positioning, curb adapters, duct connections, and coordination with electrical and gas trades. Whether you need a new installation, replacement of aging equipment, or a capacity upgrade, we have the expertise to deliver a successful project.
Ventilation Systems
Commercial ventilation encompasses far more than simple heating and cooling. We provide complete solutions including exhaust systems for commercial kitchens, makeup air units that replace extracted air, industrial ventilation for manufacturing environments, and fresh air systems to maintain indoor air quality.
Every ventilation system must be properly sized and balanced to function effectively. A poorly designed or installed system creates pressure problems, comfort issues, and code compliance failures. Our expertise ensures installation that performs as intended.
Ductwork Installation
Ductwork forms the distribution network that carries conditioned air throughout your building. We install commercial-grade ductwork for all applications, including standard distribution ducts, kitchen exhaust ducts meeting fire safety standards, and zoned distribution systems for multi-tenant buildings.
Industries We Serve
We provide specialized HVAC installations tailored to the unique needs of each sector.
Restaurants represent a significant portion of our work. Commercial kitchen ventilation requires specific expertise to ensure code compliance and effective performance. We install exhaust systems, makeup air units, and climate control solutions for dining areas.
Gyms and fitness centers need high-capacity ventilation to manage the heat and humidity generated by intense physical activity. We design and install systems that maintain a comfortable environment even during peak hours.
Warehouses and distribution centers require solutions capable of conditioning large volumes at reasonable costs. We install industrial rooftop units and ventilation systems suited to logistics operations.
Retail demands reliable climate control that keeps customers comfortable and products protected. From boutiques to shopping centers, we install systems appropriate for every scale.
Factories and manufacturing facilities present unique challenges including process heat, fumes, and worker comfort requirements. We install industrial ventilation and specialized exhaust systems.
Laboratories require precision ventilation to maintain controlled conditions and protect personnel. We install systems meeting the strict requirements of research environments.
Service Area
We serve commercial clients throughout Greater Montreal and within 100 kilometers. Our coverage includes all Montreal boroughs, Laval, the South Shore including Longueuil, Brossard, and Boucherville, the North Shore including Terrebonne and Repentigny, the West Island, and extended regions like Saint-Jerome and Saint-Jean-sur-Richelieu.
Frequently Asked Questions
What is the difference between HVAC installation and service?
Installation involves putting in new equipment or replacing existing equipment. Service includes regular maintenance, repairs, and emergency calls. We focus exclusively on installation, which allows us to offer specialized expertise without the complications of service contracts.
Why choose an installation specialist rather than a general HVAC company?
An installation specialist brings concentrated expertise and superior efficiency. We know commercial equipment in depth, we understand commercial building requirements, and we execute projects faster because it’s our only focus. General companies divide their attention between B2C service, commercial, and maintenance contracts.
What types of commercial HVAC equipment do you install?
We primarily install rooftop units (RTUs) of all capacities, ventilation systems including exhaust and makeup air, commercial ductwork, and specialized equipment for restaurants and industrial applications. We work with major commercial manufacturers.
How long does a typical installation take?
Timeline varies by project complexity. A simple rooftop unit replacement can be completed in one to two days. A new installation with ductwork may take a week or more. Restaurant ventilation projects vary by scope. We provide detailed timelines with every quote.
Do you handle permits for commercial HVAC installation?
Yes, we coordinate permit applications and required inspections as part of our installation service. Most commercial installations require permits, and we ensure all work complies with Quebec building codes.
Do you offer warranties on your installations?
All equipment we install is covered by manufacturer warranties. Our installation work is also warranted against defects. We provide complete documentation including warranty details with every project.
