A high-performance central solution perfectly suited for an existing residence in NDG
In a typical residential area of Côte-des-Neiges–Notre-Dame-de-Grâce, our AirGreen team recently completed a strategic HVAC installation aimed at completely modernizing the thermal comfort of a single-family home. The client wanted to replace an old, energy-intensive system with a reliable, quiet, and high-performance solution for the Quebec winter. After a thorough needs analysis, we recommended the installation of a MIDEA EVOX G3 1.5 ton central heat pump, a particularly relevant choice for this type of property.
Real-world challenges and AirGreen's technical approach
Building configuration and initial constraints
The building presented several constraints typical of installations in Montreal:
- Brick exterior walls requiring solid and aesthetic mounting
- Limited access for duct and piping passage
- Existing duct system to optimize rather than replace
- Restricted space for outdoor unit installation
Our team took care to design a tailor-made solution, taking these elements into account while maximizing system efficiency.
Outdoor unit installation
As seen in the project, the outdoor unit was:
- Mounted on robust wall brackets to prevent vibrations
- Installed at a strategic height to limit snow accumulation
- Connected with carefully protected and well-aligned piping
We also took care to ensure clean aesthetic integration, essential in a dense residential area like NDG.
Drainage and electrical supply management
A point often overlooked in standard installations, but essential at AirGreen:
- Drainage correctly directed to prevent any water infiltration
- Electrical connection compliant with RBQ standards
- Mechanical protection of exposed conduits
These details ensure the durability of the system and reduce the risk of future problems.
Why the MIDEA EVOX G3 is a strategic choice
Extreme heating performance
The MIDEA EVOX G3 central heat pump is designed to operate efficiently down to -30 °C, making it a perfectly suited solution for the climate of Montreal, Laval, Longueuil, North Shore, and South Shore.
Unlike traditional systems:
- Capacity retention down to -25 °C
- Stable operation even in periods of intense cold
- Significant reduction in auxiliary electric heating use
Superior energy efficiency
This model boasts impressive performance:
- SEER2: 19.0
- HSPF2: 10.1
- EER2: 12.5
This translates concretely into:
- Reduced electricity costs
- Better energy consumption management
- Constant comfort without sudden temperature fluctuations
Advantageous LogisVert subsidy
One of the decisive factors for this client was eligibility for the subsidy:
- $1764 via the LogisVert program
- Accelerated return on investment
- Transition to a greener solution
Eco-friendly R-454B refrigerant
This system uses a modern gas:
- Low global warming potential (GWP 466)
- Compliance with new environmental standards
- Future-oriented solution
Installation process: precision and rigor
Key steps carried out by our team
Here's how the installation unfolded:
- Complete inspection of the existing system
- Duct validation and necessary adjustments
- Outdoor unit installation with wall brackets
- Refrigerant line passage (3/8 - 3/4)
- 220V electrical connection
- Vacuuming (complete evacuation)
- Pressure tests and leak detection
- System commissioning and calibration
Each step was carried out according to our strict standards to ensure a durable and high-performing HVAC installation.
Final result: comfort, quietness, and efficiency
After the installation, the client immediately noticed:
- Stable temperature throughout the house
- Uniform air distribution
- Very low noise level
- Reduced energy consumption
The system also offers:
- WiFi control via application
- Smart scheduling
- Automatic adaptation to outdoor conditions
Common errors to avoid in this type of installation
Thanks to our experience in HVAC installation in Montreal and its surroundings, here are some common mistakes we systematically avoid:
- Undersizing or oversizing the heat pump
- Neglecting the quality of vacuum evacuation
- Installing the outdoor unit too close to the ground
- Poor protection of outdoor conduits
