A poorly planned commercial air conditioning installation in Laval can cost thousands — here’s how to avoid it thanks to AirGreen’s expertise
When it comes to commercial air conditioning, the stakes go far beyond basic thermal comfort. A poor decision or faulty installation can directly impact a business's profitability, customer satisfaction, employee safety, and the building’s energy efficiency. At AirGreen, we’ve been supporting businesses, retail shops, and property managers throughout Laval with their commercial HVAC projects for years, providing a rigorous, personalized approach that never compromises on quality.
In this article, we reveal the most common and costly mistakes we've encountered in Laval during countless service calls. We’ll explain how we avoid them and how our method ensures a reliable, long-lasting, and cost-efficient commercial HVAC installation.
Poor assessment of air conditioning needs: a common initial mistake
One of the most critical mistakes in any commercial air conditioning project in Laval is miscalculating the building’s thermal load. Far too often, we see businesses that have chosen an undersized or oversized system.
Undersized systems: discomfort and energy overuse
A unit that’s too small won’t be able to maintain the desired temperature during heatwaves. This leads to overworked components, premature wear and tear, and a spike in energy consumption.
Oversized systems: energy waste and short cycling
Conversely, an overly powerful unit will frequently short cycle, which reduces energy efficiency and affects humidity control. These mistakes often stem from a ballpark estimate or decisions made without technical consultation.
At AirGreen, we always conduct a detailed thermal study of every commercial space. We consider insulation, sun exposure, air volume, internal heat sources, and occupant load, to recommend the correct BTU/h capacity, tailored to your business reality in Laval.
Choosing a system unsuited for commercial use
Another common pitfall is attempting to use residential-grade systems in a commercial setting. For example, installing a residential wall-mounted heat pump in a high-traffic commercial space is a frequent misstep.
Real-life case in Laval: the wrong choice of residential unit
Recently, a convenience store on Curé-Labelle Boulevard reached out to us about recurring air conditioning breakdowns. After inspection, we found the previous installation included a 12,000 BTU wall-mounted residential unit — completely unfit for a 100 m² open commercial area.
We recommended a Fujitsu Airstage commercial system, built for continuous operation, high energy efficiency, and excellent humidity control. Since the installation, the client has reported a 30% drop in energy costs and consistent comfort, even on the hottest days.
Skimping on installation quality: the invisible but expensive mistake
Even with a top-tier unit, a poorly executed commercial HVAC installation can cancel out all the benefits. Bad unit placement, improperly sized ducts, refrigerant leaks, or faulty electrical connections are hidden issues that seriously affect performance.
Consequences of poor installation:
-
Excessive energy consumption
-
Uneven comfort in commercial zones
-
Excess noise or vibration
-
Premature compressor failure
-
Refrigerant leaks
At AirGreen, our certified technicians specialize in commercial HVAC. Each project is overseen by a technical supervisor, and our procedures include pressure testing, leak detection, duct balancing, and full system calibration.
Not following local codes or overlooking available grants
Many business owners in Laval are unaware that air conditioning system installation is regulated by municipal and provincial codes. Ignoring these rules can lead to fines, project delays, or worse — being forced to shut down certain equipment.
Example: failure to comply with current standards
During a service call on Avenue des Bois, we discovered that a central air conditioning system installed in a commercial building didn’t meet the required clearance standards from the building code. Result: water infiltration and mold growth inside the ductwork.
Our team fully brought the system up to code, including relocating the outdoor unit, redoing the insulation, and verifying all electrical connections.
At the same time, we helped the client secure a grant through Hydro-Québec’s LogisVert program, as the new system chosen (Bosch BOVA 2.0 Inverter) delivered a SEER rating above 20, far exceeding the minimum requirements.
Forgetting about HVAC maintenance: a long-term mistake
Installing the right system is just the first step. Regular maintenance of commercial air conditioning systems is key to maintaining performance, preventing breakdowns, and extending equipment lifespan.
