Installation of a FUJITSU ORION XLTH KZAH R-32 12,000 BTU wall-mounted heat pump in Delson
HVAC installation in Delson of a FUJITSU ORION XLTH 12,000 BTU heat pump with wall bracket, performing at -26°C and LogisVert subsidy. Ideal solution for Montreal and the South Shore.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
Precise and Aesthetic HVAC Installation in a Residential Environment on the South Shore
In the residential sector of Delson, on the South Shore of Montreal, we recently completed a particularly clean and well-thought-out HVAC installation of a FUJITSU ORION XLTH 12,000 BTU wall-mounted heat pump. This project perfectly illustrates our approach: combining technical performance, external aesthetics, and long-term durability.
From the first visit, several elements allowed us to define an optimal installation strategy: proximity to exterior walls, vinyl siding, limited ground space, and the need to ensure effective drainage. The client was looking for a reliable system for winter heating, without compromising the external appearance of their property.
A Heat Pump Designed for Delson Winters
Thermal Performance Adapted to the Quebec Climate
The choice of the FUJITSU ORION XLTH KZAH R-32 12,000 BTU model is not insignificant. In Delson, as everywhere on the South Shore, winter temperatures can drop well below -20 °C.
This heat pump offers:
- Efficient heating down to -26 °C
- Stable capacity even in extreme conditions
- Inverter technology for continuous modulation
- ENERGY STAR® Cold Climate certification
In practice, this means the client benefits from constant comfort, without relying excessively on electric baseboards.
Impressive Energy Efficiency
The energy performance of this model is particularly high:
- SEER2: 30.5
- HSPF2: 12.7
- EER2: 16.0
These values significantly reduce energy costs, an essential criterion for homeowners on the South Shore, particularly in Delson, where heating needs are substantial for several months.
An Outdoor Wall-Mounted Installation: A Strategic Choice
Why Avoid a Ground-Level Installation?
By analyzing the terrain configuration, our team quickly recommended a wall-mounted installation on metal supports rather than a ground-level base.
Here's why:
- Prevents snow and ice accumulation
- Protects the outdoor unit from moisture
- Improves natural drainage
- Reduces vibrations transmitted to the ground
In the project image, it is clear that the unit is installed on robust wall mounts, firmly anchored to the structure. This type of mounting is ideal for properties in Delson, where freeze-thaw cycles are frequent.
Perfect Alignment and Aesthetic Finish
One of the strong points of this installation is undoubtedly the conduit management:
- Perfectly aligned vertical pipe cover
- Color matched to the exterior siding
- Discrete routing of wiring and refrigerant lines
This type of finish is essential for maintaining a clean and professional appearance, especially in the residential areas of the South Shore.
Technical Management of Conduits and Drainage
Optimized 1/4 – 3/8 Piping
The FUJITSU ORION XLTH heat pump uses a standard configuration:
- Liquid line: 1/4 inch
- Gas line: 3/8 inch
In this project in Delson, we optimized the length of the conduits to:
- Minimize performance losses
- Avoid refrigerant overcharges
- Ensure stable long-term operation
Rigorous Drainage Testing
At AirGreen, every installation includes concrete drainage validation:
- Water test directly into the indoor unit
- Verification of natural flow
- Slope adjustment if necessary
This step is crucial to prevent future problems, especially infiltration or backflow.
Specific Challenges Encountered During Installation in Delson
Restricted Space Between the House and the Outdoor Passage
The side passage was relatively narrow, which required:
- Precise planning of the unit's position
- A compact installation without hindering circulation
- Millimetric alignment of the wall mount
Compliance with Electrical Standards
The installation also includes:
- A compliant electrical disconnect
- A secure 220V power supply
- Adequate protection according to current Quebec standards
Everything was designed to ensure safety and accessibility for future maintenance.
LogisVert Subsidy: A Concrete Financial Advantage
This model is eligible for the LogisVert subsidy of $1,200, which represents:
- An immediate reduction in project cost
- Accelerated return on investment
- A transition to a greener system
For residents of Delson, Longueuil, Brossard or elsewhere on the South Shore, this financial aid makes the installation of a high-end heat pump much more accessible.
Acoustic Comfort and Residential Integration
Indoor and Outdoor Silence
Comfort does not solely depend on temperature. Noise plays an essential role:
- 23 dB(A) indoor: virtually inaudible
- 47 dB(A) outdoor: very discreet
In this neighborhood of Delson, this characteristic is particularly appreciated, especially when units are installed near passageways or windows.
Practical Advice for Homeowners in Delson
To do after installation
- Clean filters every 4 to 8 weeks
- Keep the outdoor unit clear in winter
- Maintain a stable temperature
To avoid
- Blocking indoor air circulation
- Modifying conduits without a professional
- Ignoring unusual signs (noises, excessive ice)

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
