Costly mistakes to avoid when installing a commercial air conditioner in Laval: expert advice from AirGreen
When it comes to selecting a commercial air conditioner for your business in Laval, there’s little room for error. A poor decision can lead to high energy bills, frequent breakdowns, or the inability to maintain a comfortable temperature in your space. At AirGreen, we’re often called in to fix poorly planned installations or mismatched equipment choices, usually the result of bad planning or not understanding the specific needs of the building.
In this article, we’re sharing our expertise to help you avoid the common mistakes we see when it comes to selecting and installing a commercial air conditioning system in Laval. Our goal is to provide you with a clear, practical guide based on real on-site experience—so you can maximize comfort, energy efficiency, and return on investment.
1. Failing to properly assess the cooling needs of the space
Common mistake: Choosing a unit that’s either too small or too powerful for the space.
Why it’s a problem:
-
An undersized unit will run continuously, wear out faster, and never fully reach the desired temperature.
-
An oversized unit will cool too quickly, failing to properly dehumidify the air, reducing comfort and increasing wear.
Our AirGreen solution: We always perform a complete thermal analysis of the building. This evaluation takes into account the square footage, insulation, sun exposure, type of activity, number of occupants, and equipment in use. This is the only way to accurately determine the correct tonnage for your commercial air conditioning system in Laval.
2. Ignoring energy efficiency ratings and available grants
Common mistake: Installing an older or low-end model that consumes more energy.
Why it’s a problem:
-
Higher energy costs over time.
-
Not eligible for grants like Hydro-Québec’s LogisVert program.
Our AirGreen solution: We recommend modern, high-efficiency systems, such as Bosch BOVA R-454B commercial air conditioners, high-performance Goodman units, or Variable Refrigerant Flow (VRF) systems for larger spaces. Our experts also guide you through all available grant programs in Laval and the North Shore to help lower your upfront investment.
3. Underestimating the importance of proper HVAC installation
Common mistake: Hiring a non-specialized contractor for the installation.
Why it’s a problem:
-
Risk of improper system setup.
-
Refrigerant leaks, poorly sized ductwork, drainage issues.
-
Equipment warranty may be voided.
Our AirGreen solution: At AirGreen, every commercial installation is handled by our certified HVAC technicians, who comply with all RBQ standards. We document every step, test system performance upon startup, and provide tailored follow-up.
4. Skipping routine HVAC maintenance
Common mistake: Failing to plan for post-installation maintenance.
Why it’s a problem:
-
Dust buildup in coils and filters.
-
Reduced performance, higher consumption, unexpected failures.
-
Health risks for occupants (mold, bacteria).
Our AirGreen solution: We offer custom HVAC maintenance contracts, tailored to commercial realities. Our regular visits include deep cleaning, mechanical checks, seasonal adjustments, and preventive diagnostics. This extends your equipment’s lifespan and ensures optimal long-term performance.
5. Overlooking noise levels in a professional setting
Common mistake: Installing a noisy air conditioner in a workspace or reception area.
Why it’s a problem:
-
Discomfort for staff and clients.
-
Reduced productivity.
-
Poor professional image.
Our AirGreen solution: We install units known for their quiet operation, such as Gree U-Crown or Fujitsu KZAS wall-mounted systems with advanced soundproofing technologies. During installation, we use anti-vibration materials, insulated wall brackets, and soundproofed ductwork to minimize noise as much as possible.
6. Thinking short-term and not planning for future building changes
Common mistake: Choosing a system without accounting for future needs (expansion, change of use).
Why it’s a problem:
-
Needing to reinvest in a new system after just a few years.
-
High costs for retrofitting or upgrades.
Our AirGreen solution: We help you build a long-term vision. We offer scalable solutions, such as multi-zone or VRF systems, that can adapt to your commercial building’s evolving needs. This approach is sustainable, cost-effective, and flexible.
Real case: Commercial system installation in Laval – a successful AirGreen project
We were recently contacted by a small business in Laval preparing to open a new branch in a semi-industrial building. The owner had received three bids, all suggesting similar models—but none took into account the space’s unique setup: large glass façade, mezzanine level, and heat-generating production equipment.
After conducting a detailed thermal analysis, we recommended installing a Bosch BOVA 36,000 BTU R-454B commercial system with three indoor units, smart zoning, and a custom schedule aligned with their business hours. The result? Perfect comfort from week one, lower-than-expected energy consumption, and a thrilled client who has since hired us for other locations.
