A central solution designed for Quebec's climate realities
At AirGreen, we have been installing central heat pumps for many years in a wide variety of settings: single-family homes in Montreal, duplexes in Laval, multi-unit buildings in Longueuil, newer residences on the North Shore , and renovated properties on the South Shore . The MIDEA EVOX G3 | 5 T R454B "ADD-ON" Central Heat Pump has proven to be a concrete solution to the real needs observed in the field: replacing or upgrading an existing system, improving winter performance, and reducing energy consumption without overhauling the entire HVAC infrastructure.
This 5-tonne (60,000 BTU) model is designed for large buildings or those with high heat loads. It integrates directly into existing ductwork, making it a strategic option for replacement projects where time, budget, and space constraints are significant.
A central heat pump truly adapted to extreme cold
In the greater Montreal area, temperature variations are significant: humid summers, long winters, and sharp cold spells. The MIDEA EVOX G3 was developed to operate stably down to -30°C , with its heating capacity maintained at -25°C . In practice, this translates to consistent comfort even during cold snaps, without the need for an energy-intensive backup heating system.
During a recent installation in Laval, in a house of over 3,500 sq ft originally heated by gas, the client was looking for a high-performance electric solution eligible for LogisVert subsidies , while retaining their existing ductwork. The MIDEA EVOX G3 5 T Central Heat Pump met almost all of their heating needs, even on nights as low as -22°C, with remarkable stability of the indoor temperature.
Energy performance and measurable efficiency
Efficiency is a key concern for our customers. This heat pump boasts high SEER2 , HSPF2 , and EER2 values, reflecting true efficiency in both cooling and heating. In practical terms, this means:
-
a significant reduction in annual energy costs ;
-
improved management of operating cycles;
-
more uniform wear of the components.
The COP at -8°C remains high, which is essential in the Quebec context where sub-zero temperatures are frequent over extended periods. We have observed, on several projects in Longueuil and on the South Shore , a significant decrease in electricity consumption compared to older non-inverter central systems.
R-454B refrigerant: a responsible and compliant choice
The MIDEA EVOX G3 uses R-454B refrigerant , classified A2L. This choice reduces environmental impact while complying with current standards. For our customers, this means investing in a sustainable HVAC solution , compatible with current energy efficiency and ecological transition guidelines, without compromising on performance.
“ADD-ON” integration: a tangible advantage on construction sites
The ADD-ON concept is particularly popular when replacing existing systems. In many buildings in Montreal and on the North Shore , mechanical space is limited: low-ceilinged basements, cramped mechanical rooms, and restricted access. The modular and compact design of the indoor unit greatly simplifies installation.
At AirGreen, we have completed several projects where the MIDEA EVOX G3 Central Heat Pump could be installed where other brands would have required major modifications. This reduces:
-
construction deadlines;
-
unforeseen costs;
-
the impact of the works on the daily lives of the occupants.
Constant airflow and consistent comfort
A common problem with central systems is uneven air distribution. Thanks to advanced airflow management (CFM) and automatic adaptation to duct conditions, the EVOX G3 maintains a stable airflow even when filters are more restrictive or the ductwork has variable pressure drops.
In a multi-unit building on the South Shore , this feature has improved comfort between floors: less temperature variation, less noise and a more uniform feeling of warmth, particularly appreciated during the winter.
Modern features and intelligent control
The integrated Wi-Fi connection allows for precise system control: programming, remote adjustments, energy consumption monitoring, and simplified diagnostics. For both owner-occupiers and property managers, this feature provides real added value in terms of HVAC management and maintenance.
We consistently recommend that our customers use these tools to optimize operating ranges according to their actual habits, which helps to extend the life of the system and maximize energy savings.
Noise level and outdoor integration
With an outdoor noise level of approximately 64.5 dB(A) , the MIDEA EVOX G3 Central Heat Pump remains quiet for a unit of this capacity. During installations in dense urban environments, particularly in Montreal, this aspect is essential to respect neighbors and municipal regulations.
The outdoor unit, designed to withstand harsh weather conditions, integrates easily into existing layouts, whether it be a backyard, parking lot or a small technical space.
Guarantee and peace of mind
The standard warranty covers the compressor and parts for 12 years . Labor is not included by default, but an extended warranty is available . At AirGreen, we assist our customers in choosing the coverage best suited to their needs, based on the type of building and its intended use.
This proactive approach helps to avoid unforeseen costs and secure the long-term investment.
Why choose AirGreen for this type of installation?
Installing a 5-tonne central heat pump requires precise expertise: calculating loads, evaluating the ductwork, electrical configuration, compliance with standards, and optimizing actual efficiency. At AirGreen, we base our recommendations on concrete data from projects completed in Montreal, Laval, Longueuil, and on the North and South Shores of Montreal.
We take the time to analyze each building to ensure that the MIDEA EVOX G3 | 5 T R454B "ADD-ON" Central Heat Pump is truly the right choice, both technically and economically.
