A real-life testimony on the energy transition of a rental building in Laval
As energy-efficient renovations become increasingly important in the residential real estate sector, central heat pump installations have emerged as a strategic way to improve both energy consumption and indoor comfort. At AirGreen, we recently supported a Laval-based property manager in an ambitious project to upgrade five rental units. The goal? Replace outdated electric heating systems with high-performance central heat pumps, while maximizing government grants and minimizing disruptions for tenants.
Project Overview: A 5-Unit Building in a Residential Area of Laval
The building, built in the 1980s, included five rental units, all heated by electric baseboards. While insulation was decent, winter energy costs were skyrocketing year after year. Faced with Hydro-Québec's rising rates and the pressure to green their real estate portfolio, the manager contacted our team for a comprehensive, sustainable, and grant-eligible HVAC solution.
AirGreen’s Recommended Solution: 5 Independent Central Heat Pump Systems
After conducting a thorough thermal analysis of the building, we recommended installing five independent central systems—one per unit. Our suggestion focused on the high-efficiency Arcoaire model, featuring an inverter compressor and environmentally friendly R-32 refrigerant.
Technical Details of the Installed Systems:
-
Brand: Arcoaire (Carrier Group)
-
Type: Central air-source heat pump, multizone
-
Capacity: 24,000 to 36,000 BTU depending on unit size
-
SEER: 18 to 20 (depending on model)
-
HSPF: Over 10
-
Refrigerant: R-32 (low environmental impact)
-
LogisVert Grant Eligible: Yes, up to $5,000 per unit
These units were chosen for their quiet operation, proven reliability in Quebec’s climate, and compatibility with Hydro-Québec’s LogisVert grant program.
Technical Challenges Faced During Installation
Installing in an occupied multi-unit building presents several logistical challenges:
-
Limited access to mechanical rooms: Some units were only accessible at certain hours. We coordinated directly with each tenant to schedule work.
-
Tight mechanical space: For two units, installing the indoor coil required adjustments to drywall and ductwork.
-
Preserving exterior aesthetics: The manager insisted on a discreet integration of outdoor condensers. We used wall-mounted vibration-dampening brackets, painted to match the brick.
-
Optimized electrical connections: Our certified electrician grouped all HVAC connections into a dedicated distribution panel, enhancing safety and management.
A Carefully Planned Installation
The project was completed over 10 business days, or about 2 days per unit, strictly adhering to deadlines with no major disruptions to essential services. Thanks to our experience in multi-unit urban projects, our team successfully minimized the impact on tenants' daily lives.
Results: Improved Comfort, Lower Energy Bills, and Increased Tenant Loyalty
After the first winter following the installation, the property manager shared tangible results with us:
-
Average 35% reduction in energy bills for tenants (compared to the previous winter)
-
Zero service calls in 5 months of operation
-
More stable indoor temperatures, year-round
-
Improved tenant retention rate—some even renewed their lease due to increased comfort
-
Enhanced green reputation—the project was featured on the manager’s rental platform, attracting a new profile of eco-conscious renters
