A central installation designed for the real comfort of a home in Laval-des-Rapides
In Laval-des-Rapides, an area with both established single-family homes and renovated properties over the years, the addition of a 2.5 ton MIDEA EVOX G3 central heat pump represents much more than a simple equipment replacement. It's a complete HVAC (heating, ventilation, and air conditioning) intervention that must consider the existing structure, outdoor positioning, noise level, indoor air circulation, and the very concrete expectations of the occupants: stable heating in winter, efficient air conditioning in summer, and better-controlled energy consumption.
For this installation, our AirGreen team worked with an outdoor MIDEA unit installed on wall mounts, securely fastened to the foundation, against a brick wall. The construction site photo shows a reality we often encounter in Greater Montreal: limited outdoor space, a side facade already occupied by technical elements, a specific installation height to respect, and the need to work neatly around the building without disrupting the existing landscaping.
The MIDEA EVOX G3 was chosen to offer a high-performance central solution, adapted to the needs of a residence where heating and cooling multiple rooms from a ducted system is desired. Unlike a wall-mounted heat pump or a wall-mounted air conditioner, a central heat pump integrates into the house's ventilation network, allowing for more uniform air distribution and more consistent comfort in living areas, bedrooms, the basement, and circulation zones.
Technical and practical details that guided our intervention
Why a 2.5 ton central heat pump was the right choice
The sizing of a central heat pump is never done randomly. A capacity of 2.5 tons, or approximately 30,000 BTU, can be suitable for many medium-sized homes, but only when the building envelope, insulation quality, solar exposure, duct configuration, and occupant habits are compatible with this power.
In this project in Laval-des-Rapides, the objective was clear: to offer a solution capable of ensuring the annual comfort of the home, while avoiding two common mistakes:
- installing too small a unit, which would run for too long and struggle to reach the desired temperature during severe cold spells or heat waves;
- installing an oversized unit, which could lead to short cycling, uneven comfort, less effective dehumidification in summer, and premature wear.
The MIDEA EVOX G3 2.5 tons helped strike this balance. Its variable speed technology allows for more modulated operation than a traditional on/off system. For occupants, this translates to a more stable temperature, fewer sudden variations, and better humidity management during the warm season.
Outdoor installation on wall mounts: stability, clearance, and protection
One of the most visible elements of this installation is the positioning of the outdoor unit on metal wall mounts. This choice is not just aesthetic. In the Montreal, Laval, Longueuil, North Shore, and South Shore regions, snow accumulation, ground ice, and freeze-thaw cycles can quickly damage equipment installed too low or not properly cleared.
By installing the outdoor unit at height, we improved several important aspects:
- better protection against snow accumulation around the exchanger;
- sufficient clearance for air circulation;
- cleaner access for HVAC maintenance;
- reduced risks related to standing water or ice projections;
- increased stability thanks to a proper attachment to the foundation wall.
In the photo, we can see that the MIDEA unit is fixed in front of a foundation section, under a brick wall. This type of configuration requires particular attention: the fastening must be solid, the leveling impeccable, vibrations controlled, and refrigerant lines routed precisely. Our AirGreen technician worked on-site to ensure a neat, durable installation that complies with industry best practices.
Management of conduits, wiring, and technical access
A central HVAC installation is not limited to installing an outdoor unit. Every detail counts: the routing of refrigerant lines, electrical connections, cable protection, drainage, sealing of openings, and future accessibility for service.
In this project, the presence of a brick wall, a concrete foundation, and existing elements on the facade required a meticulous approach. We paid particular attention to the alignment of the conduits and the protection of passages to maintain a clean finish. Clients often notice the outdoor unit, but it's the less visible details that determine long-term reliability.
A common bad practice is to choose the outdoor location based solely on ease of installation. At AirGreen, we evaluate the entire context instead: noise, accessibility, clearance, winter protection, aesthetics, future service, and impact on occupants. In a dense residential area like Laval-des-Rapides, this approach makes a significant difference.
MIDEA EVOX G3: A modern central solution for the Quebec climate
The MIDEA EVOX G3 series is designed to meet the needs of homeowners who want to replace an old central system or upgrade their residential comfort. In the Quebec context, the priority is not just air conditioning. Heating accounts for a large part of the year, and a good central heat pump must be able to sustain comfort during cold periods while reducing reliance on auxiliary systems when conditions allow.
For this project, the desired benefits were:
- more stable central heating throughout the house;
- central air conditioning better distributed than a single wall-mounted unit;
- quieter operation than traditional older outdoor equipment;
- better energy efficiency depending on usage conditions;
- compatibility with a modern residential HVAC approach;
- improved comfort in distant rooms through duct distribution.
A 2.5-ton central heat pump is particularly suitable for clients who want a discreet indoor solution. Unlike multiple visible wall-mounted units in different rooms, the central system generally uses existing air vents, preserving the interior appearance while improving overall comfort.
The importance of the duct network in a central installation
When a client asks us for a central heat pump in Montreal, Laval, Longueuil, on the North Shore or the South Shore, we always emphasize one point: the outdoor unit and the indoor unit are only part of the system. The duct network plays a major role.
A high-performance unit will not deliver its full potential if the ducts are improperly sized, obstructed, poorly insulated, or unbalanced. During this type of project, we check several elements:
- the network's ability to distribute the required airflow;
- the general condition of existing ducts;
- the presence of visible or probable air leaks;
- the quality of the return air;
- compatibility with the new appliance;
- the possibility of improving certain points to optimize comfort.
In some older homes in Laval, the ducts were originally designed for a furnace, not necessarily for a modern heat pump with more precise airflow. Our role is therefore to ensure that the MIDEA EVOX G3 operates under favorable conditions, without excessive restriction or major imbalance between floors.
A clean, safe, and coordinated job site
The image of the construction site also shows an important element: the physical reality of an installation. A ladder, tools, an AirGreen technician, wall mounts, a brick wall, a foundation, conduits to connect. Everything must be executed methodically.
In Laval-des-Rapides, our team organized the work to limit interruptions for occupants. Typical steps for a central installation like this include:
- validation of the outdoor location;
- preparation of supports and anchoring;
- positioning of the outdoor unit;
- connection of refrigerant lines;
- electrical connections according to applicable standards;
- connection with the indoor unit and the existing network;
- pressurization, leak test, and vacuum;
- startup, parameter verification, and explanation of operation to the client.
This process requires precision. A modern heat pump like the MIDEA EVOX G3 must be installed by qualified professionals, especially because refrigerant and electrical connections do not tolerate improvisation. Inadequate installation can reduce efficiency, increase noise, cause breakdowns, and compromise equipment durability.
Mistakes to avoid when choosing a central heat pump
Many homeowners begin their research with a single question: which model to buy? In reality, the better question is: which system is right for the house, and who will install it correctly?
Here are the mistakes we regularly see in central heat pump projects:
Choosing solely based on price
A very low price often hides compromises: weaker supports, minimal finish, few explanations, approximate sizing, or no follow-up after installation. For a central system, these compromises can be costly in the long run.
Neglecting outdoor noise
Even a good unit can become bothersome if poorly placed. The distance from windows, neighbors, and outdoor resting areas must be considered.
Ignoring the duct network
Installing a central heat pump without evaluating the ducts can lead to rooms that are too hot, too cold, or poorly ventilated.
Installing too close to the ground
In Quebec, an outdoor unit that is too low can be partially blocked by snow. This is why the wall mounts used on this project in Laval-des-Rapides are particularly relevant.
Forgetting HVAC maintenance
A central heat pump needs regular maintenance: filters, coils, drains, outdoor clearance, and operational inspection. Good maintenance extends the system's lifespan and protects its performance.
Comfort achieved after installation
After commissioning, the occupants noticed the advantages of a well-calibrated central system: more consistent air distribution, more uniform temperature, and a reduction in the temperature difference between rooms. This is often one of the most appreciated points with a central heat pump: comfort does not depend on a single wall-mounted unit in a main room, but on a complete network that serves the entire residence.
For a house in Laval-des-Rapides, where seasons impose significant variations between summer humidity, winter cold, and intermediate periods, this type of system provides valuable flexibility. In spring and autumn, the heat pump can often maintain a pleasant temperature without immediately resorting to auxiliary heating. In summer, it ensures stable central air conditioning, with better humidity management when properly sized.
Subsidies and eligibility: a point to check before installation
Financial assistance programs, including those related to energy efficiency in Quebec, can influence the choice of a central heat pump. Eligibility depends on the exact model, capacity, certifications, current criteria, and required documents. As these programs can evolve, we always recommend validating the information at the time of quotation.
At AirGreen, we guide our clients through the usual steps: invoice, installed model, proof of installation, technical documentation, and application submission when the applicable program allows. For homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore, this support helps avoid administrative errors that could delay processing the application.

Practical advice for homeowners considering a central heat pump
Before replacing or installing a central heat pump, it is useful to prepare some information. This speeds up the assessment and allows for a more precise recommendation.
Information to have on hand
- approximate area of the house;
- year of construction;
- current heating type;
- presence or absence of existing ducts;
- current comfort issues;
- rooms that are too hot or too cold;
- desired location for the outdoor unit;
- photos of the furnace, electrical panel, and outdoor space.
Points to observe in the house
A homeowner can already note certain clues: noise in the ducts, low airflow in some rooms, high humidity in summer, unstable temperature on the upper floor, or an old appliance that frequently starts and stops. These details help our advisors better understand the situation.
Importance of a serious visit or analysis
A reliable quote for a 2.5-ton central heat pump should not be based solely on a quick estimate. The choice of model, capacity, and installation must consider the reality of the building. This is exactly what was done on this project in Laval-des-Rapides.
