In Westmount, we often work on homes with character: stone basements, narrower mechanical spaces, and existing ductwork sometimes "custom-made" over the decades. This installation perfectly fits the context: a Midea central system seamlessly integrated into an existing duct network, with meticulous finishing to ensure performance, reliability, and quiet operation , both summer and winter.
At AirGreen , our goal is not just to "install a machine". We want the system to be logical , accessible for maintenance , airtight , and to offer stable comfort in all rooms, despite the typical constraints of an older building.
A true central system, designed for the comfort of the entire house
Unlike a wall-mounted heat pump (which primarily conditions one area), a central heat pump works with an indoor air handler connected to ductwork . As a result, the treated air is distributed more evenly throughout several rooms.
In this project in Westmount, the characteristic elements of a central station are clearly visible:
-
Midea Air Manager (vertical indoor unit)
-
Plenum connecting to the main duct (metallic transition)
-
Existing conduit network (supply/return)
-
Insulated piping (refrigerant lines)
-
Condensate management with a condensate pump (essential when gravity flow is not possible)
-
Installation in a mechanical room where accessibility and sealing of the connections make all the difference
Why is a Midea EVOX G3 a suitable choice for this type of house?
For a single-family home in Greater Montreal, a central unit like the Midea EVOX G3 is often an excellent compromise: it integrates well with existing ducts, it offers very good efficiency, and it meets the real needs of the occupants: main heating, stable air conditioning, better humidity control.
In areas like Westmount, NDG, Outremont, or Town of Mount Royal, one frequently encounters:
-
variable building envelopes (partial renovations, uneven insulation)
-
deeper rooms (living room, dining room, hallways)
-
floors where air balancing is crucial
👉 A properly tuned central locking system makes all the difference.
Prominent installation details that can be observed (and why it matters)
1) Connection to conduits: the #1 performance point
We can see the work involved in the transition between the unit and the ducts. This is not an aesthetic detail: a poorly executed transition creates turbulence, noise, and flow losses.
At AirGreen, the goal is:
-
watertight joints
-
the most fluid internal surfaces possible
-
an assembly that limits vibrations
2) Insulated pipes: protection, performance, durability
The refrigerant lines are insulated and neatly bundled. Neglected insulation means:
-
loss of efficiency
-
Unwanted condensation
-
risk of moisture around the materials
Here, the assembly is clean, and the routing is designed to avoid friction and stress points.
3) Condensate pump: essential in basements
In many Greater Montreal homes, especially when the mechanical room is in the basement, natural drainage isn't always possible. The visible sump pump ensures that condensation drains properly, even when the drain is higher.
This is the kind of "discreet" component that avoids:
-
overflows
-
chronic humidity
-
damage around the unit
4) Future accessibility: maintenance and longevity
A central system must remain accessible : filters, service panel, connections, drain, etc. An overly compact installation complicates maintenance… and ends up costing the owner more.
Here, the unit is positioned in such a way as to maintain a logical access, which is a real plus.
Everyday comfort: what the customer really feels
After a well-designed central installation, customer feedback is often very concrete:
-
more uniform temperature between rooms
-
Fewer gaps between floors (especially with good balancing)
-
More stable air conditioning during heat waves
-
More comfortable heating, with a less "dry" feel than with some older systems
-
Better humidity control in spring and autumn
And in a house with stone walls, solid materials and thermal inertia, a well-calibrated central system is particularly interesting: aggressive cycles are avoided, stability is sought.
The technical points that AirGreen systematically checks on a power plant
Every house is different. But our checklist remains constant:
Air tightness and airflow
-
checking for air leaks on plenums and junctions
-
adjustments to avoid losses
-
validation of global circulation
Condensate drainage and safety
-
slope, siphon, fittings
-
lift pump if necessary
-
prevention of backflow and odors
Noise and vibrations
-
fixings, supports, rigidity of transitions
-
reduction of vibrations transmitted to the ducts
-
Optimizing acoustic comfort (important in semi-detached/terraced houses)
Distribution balancing
-
correction of hot/cold imbalances
-
recommendations if some ducts are undersized
-
register optimization when present
Common mistakes in old houses… that we avoid
In Greater Montreal, many central systems are "adequate," but not optimized. Here are the classic pitfalls:
-
Poorly fitting ductwork → air leaks, noise, uncomfortable areas
-
Poorly designed drainage → humidity, missing or incorrectly installed pump
-
Insufficient space for servicing → difficult maintenance, accelerated wear and tear
-
Insufficient insulation of the lines → condensation, loss of efficiency
An installation like the one in Westmount shows the opposite: a clean, functional, and sustainable setup.
Why this type of installation is in high demand in Westmount (and surrounding areas)
Westmount is often:
-
owners who want a clean result
-
houses where the aesthetics are preserved (no murals visible everywhere)
-
"High-end" comfort requirements: stability, silence, precise control
A Midea central heat pump is an excellent choice when you want to:
-
air-condition the whole house
-
heat efficiently
-
integrate into an existing network of conduits
-
modernize without altering the character of the house
Conclusion: a properly installed Midea control unit means peace of mind
This installation in Westmount perfectly illustrates AirGreen's approach: a well-integrated, central Midea system with execution details that make a real difference (ductwork, drainage, insulation, accessibility). The expected result: stable comfort , reliable operation, and lasting performance in the real-world context of a Greater Montreal home.
