In Sainte-Dorothée, residents are all too familiar with the reality of long winters, damp thaws… and comfort needs that don't always follow the calendar. In this residential area of Laval, AirGreen recently installed aMidea wall-mounted heat pump , a solution perfectly suited to single-family homes where the goal is efficient heating and quiet cooling as soon as the temperature rises (even during colder periods).
The photo clearly shows the outdoor unit mounted on a raised support near the foundation, with the refrigerant lines carefully protected. This type of installation is crucial: in Quebec, a heat pump's performance depends as much on the machine itself as on how it is installed.
A logical choice in Sainte-Dorothée: the wall-mounted heat pump (mini-split)
In this project, a wall-mounted heat pump (mini-split) was chosen. This is often the best option for:
-
Maximize comfort in living areas (living room, open-plan area, upstairs bedrooms)
-
Reduce energy consumption compared to supplementary electric heaters
-
Get precise air conditioning in the summer, without major renovations
-
Keeping the installation clean and free of ducts (ideal for many homes in Laval)
Mini-splits are particularly well suited to homes where insulation varies from one section to another (progressive renovations, extensions, partially finished basements), which is regularly encountered in Sainte-Dorothée.
Chosen model: a Midea Midea28 (consistent with the context)
The exact model is not legible in the image, but the configuration observed and the range commonly installed in Greater Montreal lead us to a coherent choice: Midea Midea28 , a “new generation” wall-mounted heat pump appreciated for its heating performance in our Quebec conditions (and its ability to continue to deliver comfort even when temperatures are very low).
In practice, this type of system is sought after by customers who want to:
-
Heating a large part of the house without relying solely on baseboard heaters
-
Maintaining reliable air conditioning in the summer
-
Having a stable, quiet, and easy-to-maintain solution
What the installation reveals: a pose designed for winter (and that changes everything)
In the photo, several important elements show an installation done “properly” for the Laval region.
1) Elevated outdoor unit: protection against snow and frost
The outdoor unit is installed on a raised, securely anchored metal support , which provides tangible advantages:
-
Clearance above the snow accumulation
-
Reducing the risk of the unit being “buried” during storms
-
Better protection against meltwater freezing/refreezing
-
Easier access for servicing and maintenance
In Sainte-Dorothée, where snowbanks can be significant (and sometimes blown against the walls), this height is a real plus.
2) Soil drainage: gravel and clearance
There is a gravel area visible under the unit. This is not just for aesthetic reasons:
-
The defrost water drains better
-
Less ice accumulates under the machine
-
Reduction of mud splashes in the spring
-
A more stable base over the seasons
This is exactly the kind of detail that protects the investment in the long term.
3) Protected and insulated refrigerant lines
The lines are grouped together in a black sheath/insulation, securely fastened and protected where they exit the wall. Why is this important?
-
Less heat loss (therefore better efficiency)
-
Protection against UV rays, humidity, and friction.
-
Cleaner and more durable installation
-
Reduction of the risk of poorly managed condensation
4) Outdoor electrical box: safety and compliance
We can also see an electrical disconnect nearby. This is essential for:
-
The safety of technicians during interventions
-
Compliance with good installation practices
-
A simpler interview (without risky manipulations)
Everyday comfort: what the customer actually gains
A properly installed Midea wall-mounted heat pump first provides a feeling of comfort that is quickly noticeable.
During heating (autumn, winter, spring)
-
More stable temperature in living areas
-
Fewer "peaks" of dry heat like with some portable heaters
-
Reducing reliance on electric baseboard heaters
-
Defrosting is managed automatically, without customer intervention.
With air conditioning (summer)
-
Rapid and uniform cooling
-
Precise control (temperature, mode, speed, dehumidification)
-
Quiet operation, ideal for residential areas
Our AirGreen tips for keeping your machine performing well in Laval
Even an excellent heat pump can lose efficiency if maintenance is neglected. Here are our practical (and realistic) recommendations.
To be done regularly (by the client)
-
Clean the filters of the indoor unit (as needed)
-
Keep the outdoor unit clear:
-
no snowbank stuck in front
-
no leaves/branches in spring
-
no objects stored too close
-
To be done periodically (by professionals)
-
Complete cleaning of the heat exchanger (inside/outside)
-
Checking pressures and heating behavior
-
Electrical connection check
-
Inspection of pipe insulation and fixings
Proper maintenance is often what makes the difference between a "decent" machine and a truly high-performing machine for 10–15 years .
Why AirGreen is choosing this type of installation for Sainte-Dorothée
Each neighborhood has its own realities: wind direction, clearances, foundation type, snow depth, backyard access, etc. In Sainte-Dorothée, you'll often find:
-
Houses with visible foundations and side service exits
-
Courtyards where snow accumulates against some of the walls
-
Spaces to optimize to keep a clean and safe yard
In this context, installation on a raised support , with ample clearance, clean pipe management and easy access for maintenance, is exactly what we aim for at AirGreen: efficiency + durability + clean installation .
Conclusion: a well-installed Midea offers simple (and cost-effective) comfort.
This installation in Sainte-Dorothée perfectly illustrates what we seek to deliver: a Midea wall-mounted heat pump installed intelligently for the Quebec climate, with particular attention to snow, defrosting, drainage and the durability of the components.
If you are in Laval (Sainte-Dorothée, Fabreville, Chomedey, Laval-Ouest or elsewhere) and you want a reliable heating and cooling solution without complicating your life, this is exactly the type of project we carry out daily — cleanly, solidly, and with a performance-oriented approach.
