Installing a Central Heat Pump in a Luxury Condo in Old Montreal: Challenges and Tips

Adapting to the Unique Constraints of High-End Condos in Old Montreal

Installing a central heat pump in a luxury condo in Old Montreal is far from a routine operation. In this sought-after heritage district of Old Montréal, every building has a story, refined architecture, and often complex technical constraints. At AirGreen, we’ve developed solid expertise in HVAC system installations in these specific settings, blending energy efficiency, aesthetic considerations, and compliance with municipal regulations.

Why install a central heat pump in a condo?

In high-end condominiums, thermal comfort and energy efficiency aren’t optional—they’re expected. A central heat pump offers:

  • Centralized heating and cooling for even comfort throughout all rooms;

  • A significant reduction in energy consumption, especially when compared to outdated electric or oil systems;

  • Compatibility with new environmental standards, particularly through the use of eco-friendly refrigerants like R-32 or R-454B;

  • Access to significant government grants, such as Hydro-Québec’s LogisVert program, which can offer up to $5,000 depending on the system selected.

Case Study: Installation in a Historic Penthouse in Old Montreal

In a recent project, our team was tasked with installing a Bosch BOVA 5-Ton Central Heat Pump – R-454B in a penthouse in Old Montreal, located in a century-old classified building.

Challenges encountered:

  • Strict heritage restrictions prohibiting any visible alterations to the exterior facade;

  • Concrete ceilings that prevented traditional ductwork installation;

  • Limited rooftop access for installing the outdoor unit;

  • Noise and vibrations: neighboring condo owners expected absolute quiet.

AirGreen solutions:

  • Use of flat rectangular ducts to adapt to the limited ceiling height while ensuring effective air distribution;

  • Placement of the outdoor unit on a raised, soundproofed structure, discreetly installed on a rear terrace, hidden from street view;

  • Installation of a smart control system compatible with mobile apps, offering customized comfort room by room.

Technical Details of the Installed System

The selected model – Bosch BOVA – Inverter R-454B – is a 5-ton multizone central heat pump, known for its energy efficiency and performance in Québec’s cold climate.

  • Capacity: 60,000 BTU

  • SEER: 20

  • HSPF: 10.5

  • Refrigerant: R-454B (low environmental impact, low GWP)

  • ENERGY STAR® certified

  • Eligible for the LogisVert program, with a potential grant of $4,300 in this case

Custom Installation: The AirGreen Touch

Every project we handle in Old Montréal, the South Shore, or in Laval starts with a thorough on-site assessment. Our technical team evaluates:

  • The configuration of existing ductwork

  • Thermal loss points

  • Electrical constraints

  • The specific comfort needs of each occupant

For this project, the system was commissioned in 48 hours, fully operational the next day, with no disruption to other condo owners.

Peace of Mind: Warranties and Maintenance

This type of installation is covered by:

  • 10-year parts warranty

  • 1-year full labor warranty by AirGreen

  • Custom annual preventive maintenance plan, including duct cleaning, system calibration, and refrigerant pressure checks.

Tips for a Successful Installation in a Luxury Condo

  • Anticipate the condo board’s approval: providing a detailed plan and full technical sheet of the system is essential;

  • Choose a certified installer: mistakes in a heritage building can be costly;

  • Opt for low-noise Inverter models to preserve acoustic comfort;

  • Request a personalized heat load analysis: every condo has different needs depending on orientation, insulation, and usage.
