A complete transformation of thermal comfort in an Outremont property
At AirGreen, every HVAC installation represents an opportunity to concretely improve the comfort and energy efficiency of a residence. This time, our team intervened in Outremont, an area known for its homes with distinctive architectural character, but often equipped with aging heating systems.
The project consisted of replacing an old, inefficient central system with a MIDEA EVOX G3 central heat pump of 3 tons (36,000 BTU). The client's objective was clear: to obtain a reliable solution capable of performing during Montreal's harsh winters, while reducing their energy consumption.
From the first technical visit, we identified several challenges related to the installation, but also optimization opportunities that only a professional approach could exploit.
A central heat pump designed for Quebec's realities
Exceptional performance down to -30°C
The MIDEA EVOX G3 is specifically designed for cold climates like those of the North Shore, the South Shore, and of course Montreal. It offers stable heating capacity down to -30°C, making it a particularly strategic choice to replace combustion systems or less efficient heat pumps.
During this installation in Outremont, this characteristic was essential: the house had average insulation, which required a system capable of effectively compensating for winter heat loss.
Key technical data
- Cooling capacity: 36,000 BTU
- Heating capacity: stable performance down to -30°C
- SEER2: 17.7
- HSPF2: 10.0
- EER2: 12.0
- Refrigerant: R-454B (low environmental impact)
- ENERGY STAR® (Cold Climate) Certification
- Outdoor sound pressure: 62.5 dB(A)
- Voltage: 220V
- Piping: 3/8 – 3/4
These characteristics not only ensure optimal comfort but also guarantee a tangible reduction in energy costs.
Specific challenges encountered in Outremont
Restricted space and complex existing configuration
One of the main challenges of this project was the limited space available for the installation of the outdoor unit. As can be seen on the job site, the installation had to be carried out near a raised terrace, with constraints:
- Restricted access for tools and equipment
- Need to maintain optimal air circulation
- Protection against snow and debris accumulation
We opted for a robust raised support, perfectly leveled, to ensure:
- Efficient condensation water drainage
- Protection against ground freezing
- Maximum long-term stability
Aesthetic management and visual integration
In Outremont, visual appearance is often a priority for homeowners. We therefore took care to:
- Position the unit discreetly
- Optimize duct routing to minimize visual impact
- Ensure a clean and professional finish
This attention to detail distinguishes a standard installation from a high-end one.
AirGreen installation process: rigor and precision
Key installation steps
Our team followed a strict process to guarantee the performance and durability of the system:
-
Complete thermal evaluation
Analysis of the surface area, insulation, and actual heating and cooling needs. -
Precise sizing (3 tons)
Avoid common mistakes:- Undersized system → discomfort in winter
- Oversized system → short cycles and inefficiency
-
Outdoor unit installation
- Perfect leveling
- Secure fastening
- Optimal clearance for ventilation
-
Central system connection
- Adaptation to existing ducts
- Verification of pressure drops
- Airflow optimization
-
Vacuum pull (micron test)
Crucial step often overlooked elsewhere, but essential for:- Eliminating humidity
- Preventing premature failures
-
Commissioning and calibration
- Full test in heating and cooling modes
- Adjustment of parameters for optimal performance
Concrete results for the client
Uniform thermal comfort
Within the first few days following installation, the client noticed:
- A stable temperature in all rooms
- A reduction in discrepancies between floors
- Softer, more constant heat
Reduced energy costs
Thanks to Inverter technology and ENERGY STAR® performance, the system adjusts its power in real time, which allows for:
- Less unnecessary consumption
- Better overall efficiency
- Savings on the electricity bill
Silence and discretion
The sound level of the MIDEA EVOX G3 is particularly appreciated in dense urban environments like Outremont:
- Quiet outdoor operation
- Improved indoor acoustic comfort
Available grants and return on investment
LogisVert Program
For this installation, the client is eligible for a provincial grant of up to $3720.
