In Sainte-Dorothée, many single-family homes have a semi-basement, foundation windows, and landscaping that must remain clean and functional despite snow, ice, and freeze/thaw cycles. This is exactly the kind of situation where a well-chosen and properly installed central heat pump makes all the difference.
At AirGreen , we recently installed a Midea ATOM X (confirmed brand: Midea ) for a client who wanted:
-
stable comfort (heating + air conditioning)
-
a discreet solution , without cluttering the courtyard
-
an installation designed for Quebec winters , especially with regard to the outdoor unit
The result: a clean, robust installation, optimized for performance… and for peace of mind.
Why a central heat pump in Sainte-Dorothée is often the best choice
In several areas of Laval (and particularly in Sainte-Dorothée), properties already have existing air distribution systems (ducts, plenums, centralized ventilation). In these cases, a central heat pump allows for:
-
air-condition the whole house evenly , not just one or two rooms
-
to heat efficiently during the shoulder seasons (and well beyond, depending on the configuration)
-
reduce temperature differences between the upper floor, the ground floor, and the basement
-
maintain a clean interior aesthetic (no visible wall-mounted headboards)
The Midea ATOM X fits very well into this type of project, especially for customers who want a modern, reliable and consistent solution with a house already “ready” for central.
The installed model: Midea ATOM X (central heat pump)
The photo clearly shows the Midea ATOM X outdoor unit: central format, large front fan, compact chassis, and understated design. Within the range of central systems, the ATOM X is designed to meet the realities of North America: temperature variations, the need for performance in both summer and winter, and stable operation over extended periods.
Without overwhelming the client with technical details, our role at AirGreen is to size and configure the system to suit the house (volume, insulation, windows, occupancy habits), and then install everything in a way that maximizes:
-
air circulation
-
the actual performance
-
sustainability
-
silence
-
accessibility for maintenance
Visible installation details: a layout designed to last
This installation in Sainte-Dorothée is a good example of what we like to do: clean, solid, and logical .
1) Outdoor unit on wall brackets (elevated)
The unit is installed on wall brackets fixed to the foundation, which offers several tangible advantages:
-
useful elevation against snow accumulation
-
reduced risk of obstruction by slush/ice
-
improved protection during freeze/thaw cycles on the ground
-
Easier maintenance (access, clearance, inspection)
In Laval, it's a detail that quickly becomes "non-negotiable" when you want to avoid problems in the middle of winter.
2) Location between basement windows: space and noise management
We can see that the unit is placed along a foundation wall, between two windows. This type of positioning requires careful planning:
-
clearances for air circulation
-
the distance from the openings (acoustic comfort)
-
visual cleanliness (central unit, clean lines, controlled cabling)
Our goal: that it works, but also that it “fits in” as if it had always been planned.
3) Refrigeration connections and clean inlet to the interior
We distinguish between the pipework outlet and the inlet to the house. Good execution at this stage involves:
-
limit losses and risks (protection, fixing, sealing)
-
Avoid areas where water can accumulate.
-
maintain a clean (and easy to inspect) finish
4) Electrical connection with a nearby disconnect switch
The power supply and service box are also visible near the unit. This is a crucial point for:
-
security
-
compliance
-
future maintenance (technician, diagnosis, intervention)
5) Soil management: clear and stable area
On the ground, a clear area (with stones) is visible under the device. In real life, this helps to:
-
reduce mud and splashing
-
keep the underside “clean”
-
limit stagnant moisture around the installation
How AirGreen approaches this type of project (and why it changes everything)
A central heat pump isn't just about "installing an outdoor unit." To have a system that truly performs, the project must be treated as a whole:
Typical steps we apply
-
Building analysis (surface area, insulation, orientation, habits)
-
Validation of the conduit network (leaks, restrictions, balancing)
-
Choosing the right tonnage/configuration (neither too small nor too large)
-
Intelligent outdoor installation (snow, noise, access, drainage)
-
Complete commissioning (testing, adjustments, functional validation)
It is this method that transforms a “correct” installation into an excellent one, especially in a city like Laval where winter puts everything to the test.
Comfort, savings and stability: what the customer gains on a daily basis
After installation, the benefits are very tangible:
-
Uniform temperature throughout the house (fewer areas that are too hot or too cold)
-
Efficient air conditioning in summer , without excessive noise
-
More economical heating for a good part of the year
-
Improved comfort in the basement , often a sensitive point in Sainte-Dorothée
-
A discreet system on the outside, without sacrificing performance
And above all: an installation designed for durability. Because a heat pump isn't a purchase "for 2 years." It's an investment that must remain reliable, year after year.
Recommended maintenance (essential to maintain performance)
Even with a good installation, maintenance remains key to avoiding drops in performance and preventable problems.
At AirGreen, we particularly recommend:
-
Periodic cleaning (depending on the environment: dust, leaves, pollen)
-
inspection of clearances around the outdoor unit
-
checking drainage and the condition of the supports
-
complete preventative maintenance at regular intervals
A high-performing central system is a clean, well-tuned and monitored system.
Conclusion: a properly installed Midea ATOM X offers "unsurprising" comfort
This installation in Sainte-Dorothée (Laval) perfectly illustrates our philosophy:
create a solid, clean installation, optimized for winter, and pleasant for everyday use .
The Midea ATOM X is an excellent base… but it's the quality of the installation, connections, clearances, and commissioning that determines the customer experience. And that's precisely where AirGreen stands out.
