Real HVAC installations to better understand brand differences, contexts, and customer needs in Montréal
In the world of central heat pumps, every project is unique. It’s not just a matter of brand or model—it’s a combination of factors: the building’s layout, the client’s specific needs, eligibility for government grants, technical constraints, and of course, the installer’s expertise. At AirGreen, we firmly believe that the performance of an HVAC system depends as much on the product as on the quality of the installation. Here’s a detailed review of three recent projects completed in Montréal, each featuring a different brand in specific contexts, with concrete results.
Project #1 – A single-family home in Villeray with a central Bosch BOVA 36 BIVA IDS Premium R-454B heat pump
The challenge:
In this duplex converted into a single-family home, the owner wanted an energy-efficient system compatible with federal and provincial grants, while ensuring optimal comfort across two unevenly heated floors.
Our solution:
We recommended the Bosch BOVA 36 BIVA IDS Premium central heat pump, which uses the new R-454B refrigerant, known for its reduced emissions and high energy efficiency. This model features ultra-quiet operation, a variable-speed inverter compressor, and a 36,000 BTU capacity, ideal for the home’s size.
Installation process:
-
Complete replacement of the existing 15-year-old outdoor unit with the Bosch model.
-
Modification of the main plenum to optimize air distribution between the basement and the upper floor.
-
Installation of smart thermostats with multi-zone programming.
Result:
-
Even temperature across both floors.
-
35% reduction in energy consumption over the first three months.
-
$5,000 grant obtained through the LogisVert program.
Project #2 – A renovated triplex in Rosemont with a GOODMAN GCVM97 + R-32 HEAT PUMP system
The challenge:
A real estate investor was renovating a triplex for long-term rental. He wanted a centralized system, reliable, easy to maintain, and compliant with Montréal city regulations for rental buildings.
Our solution:
We installed a GOODMAN GCVM97 high-efficiency gas furnace paired with an R-32 heat pump (model GSZC18). This system provides dual performance for heating and cooling, ensuring maximum durability for years to come.
Key steps in the installation:
-
Installation of the ductwork network for all three units, with independent ventilation for each floor.
-
Setup of a heat recovery ventilator to meet indoor air quality codes.
-
Programming of Wi-Fi-enabled smart thermostats with remote control access for the property owner.
Result:
-
Improved air quality across all three apartments.
-
A robust system with minimal maintenance requirements.
-
40% reduction in annual heating costs compared to the previous oil system.
-
Total grant of $4,700 obtained.
Project #3 – A heritage home in Plateau Mont-Royal equipped with a Fujitsu KZAH R-32 central system
The challenge:
A century-old, designated heritage home with significant constraints: limited technical space, challenging insulation, and restrictions on modifying certain exterior facades.
Our solution:
We chose the Fujitsu KZAH central heat pump, which also uses R-32 refrigerant, for its excellent performance in cold climates and its ability to operate efficiently down to -26°C. Its compact size was perfect for the limited installation space.
Installation steps:
-
Use of high-performance flexible ductwork to preserve the architectural integrity of the home.
-
Enhanced insulation for ducts running through unheated attic spaces.
-
Installation of a centralized touchscreen control system.
Result:
-
No visual impact on the home's exterior.
-
28% energy savings over the first three months.
-
Stable thermal comfort even during extreme cold spells.
-
$5,100 grant received through the federal program.
Technical comparison of the three projects
| Feature | Bosch BIVA IDS Project | Goodman GCVM97 + R-32 Project | Fujitsu KZAH R-32 Project |
|---|---|---|---|
| Building type | Single-family home | Rental triplex | Heritage home |
| BTU capacity | 36,000 | 60,000 (furnace) + 48,000 | 24,000 |
| Refrigerant used | R-454B | R-32 | R-32 |
| SEER/HSPF rating | SEER 20 / HSPF 10.5 | SEER 17 / HSPF 9.2 | SEER 19 / HSPF 10.3 |
| Grant obtained | $5,000 | $4,700 | $5,100 |
| Notable features | Quiet & variable speed | Built for rental durability | Compact & discreet |
Why these comparisons matter
Each project proves there is no one-size-fits-all solution in the HVAC industry. At AirGreen, we carefully assess:
-
The building’s thermal requirements
-
The occupants’ lifestyle and habits
-
Any technical or architectural constraints
-
Eligibility for government grants
-
The client’s long-term budget (maintenance, energy costs, lifespan)
AirGreen’s expertise: the deciding factor
These projects highlight our approach based on personalized assessment, well-informed equipment choices, and above all, meticulous installation that meets the highest standards. Thanks to our certified technicians and our guidance through the grant application process, we guarantee tangible, lasting results for every client.
