Modernizing Your Commercial Heating: Where to Start and What Benefits to Expect

Switching to a more efficient and sustainable commercial heating system: a key step for businesses in Montréal, Laval, Longueuil, North Shore and South Shore Work on gas or oil appliances, boilers and hydronic systems is handled by a licensed partner; AirGreen (RBQ licence 5645-9605-01) handles the heat pump, ventilation, refrigeration and electrical work.

At AirGreen, we know that commercial heating goes far beyond simply maintaining a comfortable indoor temperature. It’s an economic, environmental, and strategic issue for every business. In a context where energy costs are rising and expectations for energy efficiency are higher than ever, upgrading your heating system becomes a top priority. Whether you're a property manager, the owner of a small business, or responsible for an industrial complex, understanding how to begin this transition and the benefits it brings is the key to making a smart investment.

Why consider upgrading your commercial heating system?

Modernizing a commercial heating system is much more than just replacing equipment. It’s a strategic opportunity to:

• Lower your energy bills in a sustainable way.

• Improve thermal comfort for employees and customers.

• Comply with evolving environmental regulations.

• Access government and provincial grants.

• Increase the value of your commercial property.

Our team at AirGreen supports businesses every day across Montréal, Laval, Longueuil, the North Shore, and the South Shore that want to take this energy-efficient leap in a structured and cost-effective way.

Step 1: Diagnosing your current heating system

Before making any decisions, it’s essential to understand the weaknesses and limitations of your existing heating system. At AirGreen, we conduct a comprehensive technical analysis:

• Condition of the equipment (boiler, unit heater, central heat pump, gas or electric furnace).

• Actual vs. optimal energy performance.

• Uneven heat distribution across building zones.

• Current maintenance costs.

• History of breakdowns or irregular operation.

This initial step helps determine whether an upgrade, an energy source conversion (e.g. gas to electric), or a complete overhaul is the best approach.

Step 2: Choosing the right technologies for your building

There is no one-size-fits-all solution. Every building has its own constraints: surface area, space configuration, insulation type, specific needs per sector, hours of operation, etc. Based on these factors, we offer tailored solutions:

High-efficiency central commercial heat pumps

Central heat pumps, like the Bosch BOVA or FUJITSU AIRSTAGE J-series models, provide both heating and cooling for large spaces efficiently, offering:

• Reduced energy consumption (up to 40% savings compared to traditional systems).

• Versatile installation options (roof, wall, or mechanical room).

• Reversible systems for summer comfort as well.

Electric or hybrid (dual-energy) boilers

In buildings already equipped with hot water or air distribution networks, replacing an old oil or gas boiler with an electric or hybrid boiler is often a smart move—especially since these are eligible for Hydro-Québec subsidies (worth thousands of dollars).

Unit heaters and air curtains for commercial entrances

For garages, warehouses, or retail stores with frequently open exterior doors, we recommend installing modern unit heaters or smart air curtains, which help minimize heat loss while maintaining a comfortable indoor climate.

Step 3: Evaluating available financial incentives

We know the assistance programs for businesses well, notably Hydro-Québec’s programs for businesses (Efficient Solutions program) and the Government of Québec’s ÉcoPerformance program, and we prepare your projects so they are eligible for partial funding. This assistance can cover:

• Part of the equipment and installation costs (the business pays at least 10% of eligible costs under the Efficient Solutions program).

• Bonuses for switching from fossil fuels to electric systems.

• Rewards for reducing greenhouse gas emissions.

Step 4: Planning and executing the installation

At AirGreen, every installation is planned with precision:

• Thermal load studies and energy simulations.

• Selection of the optimal system based on your building’s operational cycle.

• Minimizing disruption to daily operations (night or weekend installations).

• Full compliance with CSA, RBQ, and insurance standards.

Our certified technicians ensure safe, long-lasting, and code-compliant installation, with full documentation for audit or grant purposes.

Step 5: Follow-up, maintenance, and ongoing optimization

Once the installation is complete, our support doesn’t stop there. We offer custom maintenance contracts, including:

• Seasonal checkups (calibration, pressure, electrical testing).

• Duct and filter cleaning.

• Heating curve adjustments based on weather.

• Quick technical support for unforeseen issues.

Our commercial clients in Montréal, Laval, and beyond trust us for our responsiveness, transparency, and attention to detail.

Real example: Renovating a building in Laval

One of our clients, the owner of a 12,000 sq. ft. medical centre in Laval, was facing high heating costs due to an outdated natural gas boiler. After a full assessment, we recommended installing a central FUJITSU KZAH R-32 heat pump system, backed by an electric backup boiler.

Results after 12 months:

• 38% reduction in energy bills.

• Fewer complaints about thermal discomfort.

• Financial assistance: Hydro-Québec’s programs for businesses and ÉcoPerformance.
