Energy-Efficient Modernization: How a Warehouse on the South Shore Saved 30% on Heating Costs (Real Case Study)

A Showcase Commercial HVAC Project on the South Shore: Efficiency, Comfort, and Lasting Savings

In the world of commercial heating, every project is unique. Yet, some cases stand out as true benchmarks, demonstrating how a strategic approach and technical expertise can transform an energy-hungry building into a high-performance, comfortable space. That’s exactly what we recently achieved at AirGreen, during a commercial HVAC installation in a logistics warehouse located on Montréal’s South Shore. This real-life case illustrates how we helped our client cut heating costs by 30%, while improving comfort and operational efficiency.

Initial Challenges: An Aging Warehouse with Major Energy Losses

This 2,500 m² industrial warehouse located in Boucherville (South Shore) was operating with an outdated natural gas forced-air heating system that was over 20 years old. Employees often complained about uneven temperatures, especially in loading zones where doors were frequently opened. Winter gas bills regularly exceeded $8,000/month.

Our mission was clear: modernize the heating system, reduce energy bills, qualify the building for grants, and ensure reliable performance even during Québec’s extreme winter cold.

The AirGreen Solution: A High-Efficiency Central Heat Pump Tailored for Commercial Needs

After conducting a thermal imaging assessment, precise measurements, and multiple energy simulations, our team recommended the installation of a Bosch BOVA 5T central heat pump (60,000 BTU), integrated with a Bosch BVA modular air handler, all running on R-454B refrigerant — a next-generation fluid, more eco-friendly and compliant with 2025 environmental standards.

Why Choose the Bosch BOVA + BVA System?

• High energy efficiency: SEER 20 / HSPF 10.5

• Direct reduction of gas consumption: complete replacement of combustion-based heating

• Inverter technology: continuous modulation for stable comfort and optimized energy use

• Reversibility: provides cooling in summer (air conditioning)

• Grant eligibility: approved for Hydro-Québec’s LogisVert program, amount received: $7,500

Project Execution: A Careful, Well-Planned Installation

Our work was carried out over a 4-day period, without disrupting the company’s operations:

1. Day 1: Removal of the old gas unit and preparation of the mechanical room.

2. Day 2: Installation of the Bosch BVA air handler and air ducts adapted to 7-meter ceiling heights.

3. Day 3: Installation of the outdoor Bosch heat pump (BOVA) with reinforced floor mounting for industrial setting.

4. Day 4: Programming of smart thermostats by zone and full system commissioning.

We also installed inspection hatches and connected temperature sensors to enable ongoing system performance monitoring throughout the seasons.

Results Observed After 3 Months of Operation

The results were not only positive — they were remarkable:

• 30% reduction in heating bills in just the first quarter

• Significantly improved thermal stability throughout the warehouse, including loading zones

• Increased comfort for staff, boosting productivity

• Lower carbon footprint by eliminating natural gas and switching to green electricity

Client Testimonial: A Tangible Success

“We were skeptical at first, especially about whether a heat pump could warm such a large space during extreme cold. But the results exceeded our expectations. AirGreen handled everything — from the analysis to the installation — with professionalism and precision.”
— Operations Director, Entreposage LogiSud Inc., Boucherville
