Real Case: How a Business in the North Shore Cut Its Heating Bill by Two-Thirds with One Simple Strategy

A challenge many Québec businesses know all too well

On the North Shore, many commercial and industrial businesses struggle to keep their buildings warm in winter without blowing up their energy budget. That was exactly the case for a manufacturing company in Boisbriand, who contacted us after seeing a 38% increase in their electricity bill within a year. Their old electric furnace was poorly suited for the high-ceilinged workspace, creating cold zones in the shop and constant complaints from employees.

Technical audit by AirGreen: identifying losses and boosting performance

Our technical team quickly went on-site to conduct a full HVAC assessment of the premises. We discovered that the heating system was oversized, poorly distributed, and that the ductwork had major thermal leaks. On top of that, there was no smart control system to adjust heating based on actual building occupancy or working hours.

Our proposed solution was built around three simple but highly effective pillars:

• Replacing the old unit with a high-efficiency central heat pump

• Reconfiguring the air distribution for even comfort

• Installing a zoned smart control system

Strategic choice: a BOSCH IDS Premium 3 Ton Central Heat Pump

We installed a Bosch IDS Premium R-454B 3 Ton central heat pump, perfectly sized for the production floor and administrative offices. This Inverter model with a modulating compressor allows for precise temperature control and delivers optimal performance—even in freezing cold. Plus, the R-454B refrigerant significantly lowers the environmental impact of the system.

Technical details of the installation:

• Brand: Bosch

• Model: IDS Premium R-454B

• Capacity: 36,000 BTU (3 Tons)

• Energy Efficiency Rating: SEER 20 | HSPF 10.5

• Refrigerant: R-454B – Low GWP

• Control: Smart thermostat with 4 independent zones

• Grant: Eligible for Hydro-Québec’s LogisVert program — $2,430 subsidy obtained

Installation process: precision, adaptability, and efficiency

The installation was completed over four business days, with no disruption to the company’s operations. Our technicians first dismantled the old system and then resealed and reinsulated the overhead ducts. The new heat pump was installed on a concrete base on the side of the building and protected by a custom-made metal shelter.

We integrated smart thermostats into key zones, enabling heating to be adjusted based on activity (meeting rooms, production floor, warehouse).

Concrete results: more comfort, drastically reduced costs

Three months after installation, the results were spectacular:

• 68% reduction in energy bills during the first winter

• Consistent thermal comfort across the entire building

• Fewer employee complaints and improved productivity

• Easier maintenance thanks to an accessible system layout

What this company learned:

• You don’t need to invest in complex systems to reduce costs.

• A good HVAC assessment done by experts can transform your building’s energy performance.

• Available grants like LogisVert can greatly lower acquisition costs.

• A central Inverter heat pump is perfectly suited for commercial and industrial SME needs.
