A complete transformation of residential comfort thanks to a high-performance central heat pump
At AirGreen, we recently completed a major HVAC installation in Brossard, on the South Shore, involving a MIDEA EVOX G3 3-ton (36,000 BTU) central heat pump. This project perfectly illustrates our rigorous approach, advanced technical expertise, and our ability to adapt high-performance solutions to the specific realities of Quebec homes.
In this single-family residence, the client wanted to replace an old inefficient central system that resulted in high energy costs and uneven thermal comfort. We therefore recommended and installed a MIDEA EVOX G3 central heat pump, renowned for its performance in cold climates, energy efficiency, and reliability.
Why the MIDEA EVOX G3 was the ideal choice for this Brossard home
Exceptional performance in Quebec's climate
The MIDEA EVOX G3 central heat pump is designed to provide stable heating down to -30°C, an essential criterion for the harsh winters of Brossard, Montreal, Laval, Longueuil, and the South Shore.
In this project, the house had:
- A medium-sized area with two floors
- An existing duct system in good condition
- Significant temperature variations between rooms
Thanks to its ability to maintain consistent performance even in extreme cold, this heat pump has allowed for:
- Uniform heating throughout the house
- A significant reduction in reliance on auxiliary heating
- An immediate improvement in overall comfort
Energy efficiency and concrete savings
This model displays solid performance:
- SEER2: 17.7
- HSPF2: 10.0
- EER2: 12.0
- ENERGY STAR® (Cold Climate) Certification
These characteristics translate into:
- Optimized energy consumption
- A significant decrease in electricity bills
- Better indoor humidity control
In this specific case in Brossard, the client observed an improvement in thermal stability and a reduction in excessive system use within the first few weeks.
Full installation process in Brossard
Initial technical analysis
Before any installation, our experts carried out:
- A complete inspection of existing ducts
- An evaluation of BTU requirements
- A check of electrical capacity (220V required)
This step is crucial to guarantee a durable and efficient HVAC installation.
Challenges encountered on site
This project presented several technical challenges:
1. Restricted space for the outdoor unit
The outdoor unit had to be installed close to the wall, near landscaping (garden and terrace).
AirGreen Solution:
- Installation on robust wall brackets
- Precise adjustment to ensure good airflow
- Vibration protection
2. Management of refrigerant lines
The passage of ducts required a clean and discreet route.
AirGreen Solution:
- Use of high-quality insulated conduits (3/8 - 3/4)
- Impeccable aesthetic finish
- Mechanical protection against bad weather
3. Airflow optimization
The existing duct system had to be adjusted to take full advantage of the new heat pump.
AirGreen Solution:
- Airflow calibration
- Register adjustment
- Complete static pressure check
Installation and commissioning
The complete installation was carried out in one day, including:
- Installation of the MIDEA EVOX G3 (MO1SE-H36B-2A) outdoor unit
- Installation of the MAUSE-H36B-2A indoor unit
- 220V electrical connection
- Vacuum pull (rigorous micron test)
- Pressure and operation checks
We always insist on a perfect vacuum pull, ensuring the absence of moisture and guaranteeing the longevity of the system.
Advanced technology integrated into the MIDEA EVOX G3
M-Power Inverter Compressor
This technology allows for:
- Intelligent power modulation
- Reduced start/stop cycles
