Strategic HVAC Modernization for Lasting Comfort in Anjou
In a residential neighborhood in Anjou, we recently completed a complete HVAC installation, replacing an aging central system with a 3-ton MIDEA EVOX G3 central heat pump. This project perfectly illustrates the current challenges faced by homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore: improving indoor comfort while reducing energy costs, without compromising winter performance.
From the first technical visit, it was clear that the client was looking for a reliable solution to face Quebec's harsh winters, while optimizing summer air conditioning. The choice of the MIDEA EVOX G3 quickly stood out due to its advanced technical characteristics and its compatibility with existing installations.
A Central Heat Pump Designed for Quebec's Climate
Heating Performance Down to -30°C
The MIDEA EVOX G3 central heat pump installed in Anjou offers exceptional heating capacity down to -30°C, a crucial criterion in our region. Unlike many standard systems that lose efficiency in very cold weather, this model maintains stable performance thanks to its advanced Inverter compressor.
In this specific project, the client previously used an inefficient hybrid system during periods of intense cold. As soon as the new unit was commissioned, the difference was immediate:
- faster temperature rise
- uniform heat in all rooms
- significant reduction in the use of electric auxiliary heat
ENERGY STAR® Certified Energy Efficiency
With a SEER2 of 17.7, an HSPF2 of 10.0, and ENERGY STAR® (Cold Climate) certification, this heat pump is a wise choice for homeowners looking to reduce their energy consumption.
In the case of this residence in Anjou, we estimate a significant drop in heating costs from the first year, particularly in winter when energy performance makes all the difference.
Technical Challenges Encountered During Installation
Adaptation to an Existing System
The building was equipped with an old central system with air ducts in good condition, but presenting certain constraints:
- limited mechanical space
- restricted basement access
- uneven air distribution between floors
Our team therefore had to adapt the installation to maximize the performance of the central heat pump without requiring a complete reconstruction of the duct network.
Solutions Implemented by AirGreen
We applied several technical adjustments:
- Rebalancing of the duct network to ensure optimal air circulation
- Installation of a smart control system with integrated WiFi
- Complete verification of airtightness and airflows
- Integration of the system with a modern thermostat for precise control
Thanks to these interventions, the client now benefits from homogeneous heat and air conditioning distribution, even in distant rooms.
Technical Details of the Installed MIDEA EVOX G3
Here are the key specifications of the installed system:
- Capacity: 3 tons (36,000 BTU)
- Refrigerant: R-454B (low environmental impact)
- Voltage: 220V
- Outdoor Dimensions: 37.25 x 16.13 x 31.88
- Outdoor Sound Level: 62.5 dB(A)
- Piping: 3/8 – 3/4
- Integrated WiFi: yes
This model is also distinguished by its silent operation and its ability to maintain constant comfort without temperature fluctuations.
An Installation Designed to Last
Key Project Stages
At AirGreen, every HVAC installation follows a rigorous process. For this project in Anjou:
-
On-site technical evaluation
Complete analysis of thermal needs and existing system. -
Site preparation
Installation of outdoor support, secure fastening, and surface protection. -
Outdoor unit installation
Strategic positioning to reduce noise and optimize air circulation. -
Piping and duct connection
Strict adherence to standards to guarantee efficiency and durability. -
Performance tests and calibration
Verification of optimal operation before delivery to the client.
Importance of Vacuum Pull-Down and Testing
As with all our installations, we carried out a thorough vacuum pull-down and pressure tests to ensure the absence of leaks and the longevity of the system. These steps, often neglected by some installers, are essential to guarantee stable performance over several years.
Grants and Project Profitability
LogisVert Grant
This model is eligible for a provincial grant of up to $3720, a major financial advantage for homeowners.
We assisted the client through all administrative procedures to simplify obtaining this aid.
Return on Investment
Thanks to:
- high energy efficiency
- reduced electric auxiliary heat
- cold climate performance
the client will be able to amortize their investment over a reasonable period while enjoying superior comfort.
Testimonial and Customer Feedback
A few weeks after the installation, the client shared their impressions with us:
- constant temperature throughout the house
- significant reduction in outdoor noise
- simple use via the mobile application
- improved overall comfort, summer and winter
This type of feedback is common for MIDEA EVOX G3 central heat pump installations carried out by our team in Montreal, Laval, Longueuil, the North Shore, and the South Shore.
