Improving energy efficiency for businesses in Montréal isn’t just an option—it’s a necessity. At AirGreen, we understand the real challenges that small and medium-sized businesses face when it comes to rising energy costs. That’s exactly why our team recently completed an outstanding HVAC project, cutting the electricity consumption of an SME located in the Rosemont–La Petite-Patrie district of Montréal by more than 50%, thanks to the installation of a high-efficiency 18,000 BTU Gree Lomo wall-mounted air conditioner. This installation story offers a precise, technical, and human look at our work, with a tailor-made approach that perfectly illustrates AirGreen’s expertise.
A Montréal SME Struggling with Unsustainable Energy Bills
This food processing SME had been relying on an outdated and energy-draining air conditioning system that was no longer capable of properly regulating the temperature in its production spaces. Employees constantly complained about the overwhelming heat in summer, and electronic equipment was suffering from significant temperature fluctuations.
The owner was looking for a cost-effective solution that could be deployed quickly, without disrupting operations. He also wanted a unit that was eligible for local energy-efficiency grants available in Montréal.
Technical Evaluation and Strategic Choice of the Gree Lomo Wall-Mounted Air Conditioner
During our first visit, our technicians carried out a comprehensive thermal evaluation of the premises, taking into account:
-
the total surface area to be cooled (about 1,000 sq. ft.),
-
the layout of furniture and equipment,
-
the insulation quality of exterior walls,
-
sun exposure of glass façades,
-
and peak heat generated by operating machinery.
Following the analysis, our team recommended installing a Gree Lomo 18,000 BTU wall-mounted air conditioner, a model known for its reliability, Inverter technology, and most importantly, its low energy consumption, with Energy Star certification.
This unit uses R-410A refrigerant, which is safe for the ozone layer, and is rated among the most efficient in its class, with a SEER above 20. It is also eligible for a $1,704 LogisVert grant from Hydro-Québec, significantly lowering the total investment for the company.
Installation Details: Fast, Efficient, and Discreet
We scheduled the installation for a full day, outside of production hours to avoid any disruption to business operations. Here’s how the job unfolded:
-
Indoor unit installed in the administrative office, placed high on the wall for optimal air distribution.
-
Outdoor unit mounted on a vibration-dampening slab, with raised supports to prevent snow accumulation during winter.
-
Wiring and refrigerant lines routed discreetly through utility walls with no visible damage.
-
An optimized drainage system was integrated, essential for this type of commercial space.
-
Commissioning and full system testing, followed by a detailed walkthrough for the owner on temperature controls, eco modes, scheduling, and maintenance tips.
Immediate Impact on Electricity Consumption
In the first month after installation, the owner reported a 52% drop in their electricity bill compared to the same period the previous year. Thanks to the Inverter technology, the wall-mounted air conditioner’s compressor adjusts its output in real-time based on ambient temperature, reducing energy-intensive startup cycles.
The workspace is now stable, comfortable, and properly climate-controlled. Employees noticed a clear improvement in air quality and a quieter working environment.
