The world of commercial air conditioning in Montreal, Laval, and Longueuil is far more complex than it may seem. Behind every high-performance HVAC system, there’s a team of dedicated professionals working daily to install, configure, and optimize systems designed to ensure comfort and energy efficiency for businesses. At AirGreen, our installation team embodies this expertise in the field, day after day. In this article, we take you through an entire day alongside our team, for a full behind-the-scenes immersion into our trade.
The Start: Thorough Preparation and Precise Logistics
Every day starts early at our Montreal headquarters. By 6:30 AM, our technicians are arriving, syncing up schedules, reviewing installation plans, and carefully loading the vehicles. Equipment — wall-mounted air conditioning units, ducts, mounting brackets, specialized tools, refrigerant, safety devices — is meticulously checked.
This meticulous preparation avoids any time loss on site. The team assigned to the commercial air conditioning of a pharmacy in Laval reviews the client’s file: total surface area, space constraints, ventilation codes, type of building, outdoor compressor placement.
On Site: Efficiency, Coordination, and Adaptability
Arriving on site by 8:00 AM, the technicians get straight to work. In this pharmacy located in central Laval, the job is to install two wall-mounted commercial air conditioning Fujitsu Airstage units, each 24,000 BTU, powered by a centralized outdoor compressor, rated SEER 21 and eligible under the Hydro-Québec LogisVert program.
The main challenge here: a narrow drop ceiling and fragile wall structure. After careful assessment, the team decides to anchor using chemical bolts and route the refrigerant lines through the technical mezzanine.
A Human Synergy That Makes the Difference
At AirGreen, we believe excellence also comes from communication in the field. The electrician arrives at 10:00 AM, and within 30 minutes, coordination with the HVAC technicians is seamless. While part of the team prepares wall brackets, the others drill through the necessary areas for the drainage piping.
Our efficiency comes from technical expertise, but also from a deep mutual understanding of everyone’s role. This allows us to stay on schedule without ever compromising quality.
A Well-Deserved Break, but Always on Duty
Around noon, the technicians take a short break, usually on site or in a nearby park. But the phone is never far. Our team leader responds to an urgent call from a restaurant in Longueuil dealing with a central system failure. Thanks to our flexible dispatch network, another team is redirected immediately.
The Afternoon: Calibration, Testing, and Finishing Touches
The core of the afternoon is dedicated to system startup. Pressure testing, nitrogen purging, vacuum pulling, airflow calibration — every step is critical. Programming remote controls, adjusting temperature to match the business’s specific needs, and explaining the setup to the site manager: everything is covered.
Aesthetically, our technicians install discreet PVC pipe covers to ensure a clean and professional look in the commercial space. Visual appeal is a crucial factor, especially in commercial air conditioning where the client's brand image is at stake.
Back to HQ and Client Follow-Up
The day ends around 5:00 PM. Back at our Montreal base, vehicles are cleaned, installation reports completed, and grant documentation prepared. One of our administrative team members contacts the client to confirm satisfaction, send the user manuals, and explain how to apply for available tax credits.
Testimonials: Satisfied Commercial Clients
Our installations speak for themselves, but our clients even more so. Here’s what a supermarket manager from the South Shore recently said:
“The AirGreen team was impressively efficient. Fast installation, neat work, and clear explanation of the system. Thanks to them, we now have optimal comfort for both our employees and customers.”
And from the North Shore, a medical clinic manager added:
“What I appreciated most was their transparency, punctuality, and flawless work quality. I highly recommend them to all commercial building managers.”
Common Mistakes We Help You Avoid
In the world of commercial air conditioning, some mistakes are all too common: oversizing the equipment, poor unit placement, inadequate drainage or electrical wiring. At AirGreen, we’ve seen too many poorly installed systems that harm energy efficiency and drive up long-term costs.
That’s why our local expertise in Montreal, Laval, Longueuil, the North Shore and South Shore is such a valuable asset. We know the reality of commercial buildings in each sector, the specifics of local urban planning, and the regulations in place.
