A technology built for Québec winters and the reality of commercial buildings
In a context where energy efficiency, cost-effectiveness, and occupant comfort are major concerns for every building manager, hybrid commercial heating is increasingly becoming the solution of choice. Combining performance, flexibility, and energy savings, this HVAC heating technology optimizes consumption while adapting to the harshness of Montréal winters. At AirGreen, we’ve developed field-proven expertise in hybrid system installations throughout Montréal, Laval, Longueuil, the South Shore, and the North Shore, and this article is designed to shed light on the real-world benefits of this innovative solution.
Understanding how a hybrid heating system works
A hybrid heating system combines two complementary heat sources: typically a central heat pump (electric-powered) and a natural gas or oil-fired boiler. The system automatically switches between the two sources depending on the outdoor temperature and the energy performance of each.
Smart switching based on temperature
When temperatures are mild, the central heat pump (often a high-efficiency model like the Bosch BOVA or the Goodman R-32) takes care of heating with optimal performance. When it gets very cold, the system automatically switches to the boiler, which is more effective in extreme cold. This automatic switchover helps optimize energy bills without compromising comfort.
Why choose hybrid heating for a commercial building?
1. Significant energy savings
Integrating a hybrid system allows you to reduce gas or oil consumption, especially during the mid-seasons. Based on feedback from our clients, savings can reach up to 35% on annual heating costs.
2. Consistent comfort throughout the building
Thanks to a well-designed heat distribution, occupants enjoy steady comfort, without the temperature fluctuations often found in conventional systems.
3. Boosting property value
More and more tenants and businesses are seeking out buildings with a smaller carbon footprint. Installing a high-performance hybrid system improves a building’s rental appeal and becomes a major asset during resale or lease negotiations.
Case study: Hybrid installation in a commercial building in Laval
Earlier this winter, we were hired to replace an outdated gas heating system in a three-story office building in Laval housing over 120 people. After a full energy analysis, we installed:
-
A Bosch BOVA 5 Ton central heat pump with high efficiency (SEER 20 / HSPF 10.5)
-
A modulating gas boiler with 200,000 BTU
-
A smart auto-switch control system based on outdoor temperatures
-
An upgraded ductwork network for more even distribution
Result: a 29% reduction in annual gas consumption, an estimated ROI of less than 4 years, and tenants thrilled with the improved comfort.
Available grants for hybrid heating in Québec
Current financial assistance programs
Installing a hybrid system can qualify for several programs, depending on location and building type:
-
Hydro-Québec – LogisVert commercial: potential grant for the heat pump portion
-
Transition Énergétique Québec (TEQ): support for businesses aiming to reduce fossil fuel use
-
Gaz Métro / Énergir: rebates for purchasing high-efficiency boilers combined with a heat pump
At AirGreen, we handle all the administrative steps to make sure our clients take full advantage of these programs.
What every manager should check before installation
1. Compatibility with existing systems
We assess every project in detail to determine whether the ductwork, ventilation, or central controls need updating. A full energy audit is carried out free of charge by our experts.
2. Proper sizing for actual heating load
A common mistake is over- or under-sizing the heat pump or boiler. At AirGreen, we use advanced simulation software to accurately calculate heating needs based on surface area, insulation, building orientation, and more.
3. Quality of the installed equipment
We only use brands that are reliable, tested, and suited to the commercial requirements of the Québec market, such as Bosch, Goodman, Trane, or Fujitsu for the heat pump.
Mistakes to avoid with a commercial hybrid heating system
-
Installing a hybrid system without smart automatic switchover
-
Neglecting regular maintenance of both heating systems
-
Poor calibration of the switchover temperature threshold
-
Assuming a hybrid system is “plug-and-play” with no need for adjustments
We’ve often been called in to fix poorly executed installations done by less experienced contractors. The success of a hybrid heating system relies above all on HVAC engineering expertise, precise installation, and personalized post-installation follow-up.
