A Tailored HVAC Solution for Income Properties in Montréal
In Montréal’s rental property landscape, landlords face unique challenges when it comes to modernizing heating and cooling systems. At AirGreen, we recently completed the installation of a central heat pump in a 6-unit multiplex located in the Rosemont–La Petite-Patrie borough of Montréal. This complex but strategic project is a perfect example of our ability to tailor our HVAC solutions to the realities of the rental market while maximizing comfort, energy efficiency, and property value.
Project Context: A 6-Unit Building Undergoing Energy Transformation
The building owner, Mr. Lefebvre, wanted to eliminate the individual electric baseboards in each unit, which were too energy-consuming and hard to manage. His goal: to centralize the heating and cooling system, reduce overall energy costs, and take advantage of the LogisVert subsidies offered by Hydro-Québec for energy-efficient retrofits.
The building was a three-storey structure with six residential units of varying sizes and limited access to the basement. A major challenge that we tackled with precision.
Equipment Selection: Performance, Reliability, and Grant Eligibility
After conducting an in-depth energy assessment, our team recommended the installation of a BOSCH BOVA36HDN1-M20G central heat pump, paired with the BVA36WN1-M20 indoor air handler. This high-efficiency inverter system, using the eco-friendly R-454B refrigerant, was not only compatible with the building’s technical requirements but also eligible for the LogisVert program, with an estimated rebate of $4,392.
Key Features of the Installed System:
-
Brand: Bosch
-
Model: BOVA36HDN1-M20G (heat pump) + BVA36WN1-M20 (air handler)
-
Capacity: 36,000 BTU
-
Type: Central inverter heat pump (variable speed)
-
Refrigerant: R-454B, low Global Warming Potential (GWP)
-
Efficiency: Up to 18 SEER, up to 9.5 HSPF
-
Eligibility: LogisVert grants (Hydro-Québec), federal GHG-reduction grants
Key Installation Steps and How We Overcame Technical Constraints
Assessment and Technical Planning
We started with a detailed building assessment, analyzing thermal distribution and structural limitations. The reduced crawl space height and reinforced concrete walls required meticulous planning for ductwork distribution.
Installation Process
-
Removal of old electric baseboard heaters in each unit
-
Installation of galvanized rigid ductwork to serve each apartment
-
Integration of a zoning system to allow independent temperature control per unit
-
Outdoor compressor installed on an insulated floating pad, backyard side, with acoustic dampeners to comply with municipal noise regulations
-
Installation of Wi-Fi programmable thermostats for each tenant
Challenges Faced
-
Coordinating work without disrupting tenant routines
-
Routing ductwork through existing ceilings without major demolition
-
Upgrading insulation in some basement areas to prevent thermal losses
Results and Real Benefits for the Property Owner
Since the system was activated, tenants have reported greater comfort year-round. The system operates quietly, consistently, and uses significantly less energy than the previous electric setup.
For the landlord, the benefits are many:
-
Over 30% reduction in annual energy costs
-
Increased property value (greater tenant appeal and higher rent potential)
-
Access to over $4,000 in rebates
-
Centralized maintenance, making long-term management easier
-
Ability to individually monitor usage thanks to smart thermostats
