Installation of a FUJITSU ORION XLTH KZAH R-32 12,000 BTU wall-mounted heat pump in Saint-Constant

A Discreet and Strategic HVAC Installation in a Residential Workspace

In Saint-Constant, on Montreal's South Shore, our AirGreen team recently completed an installation of a FUJITSU ORION XLTH 12,000 BTU wall-mounted heat pump in a multi-functional room used as both an office and a living space. This project perfectly illustrates how a well-thought-out HVAC installation can transform the thermal comfort of a room while adhering to very specific layout constraints.

From our first visit, several key elements guided our approach: a relatively low ceiling, a restricted wall corner, the presence of a workstation (screen, microphone, articulating arm), and an adjacent window influencing heat loss. The client was looking for a solution that was quiet, efficient for winter heating, and visually discreet.

We recommended and installed the FUJITSU ORION XLTH KZAH R-32 | 12,000 BTU, a heat pump perfectly suited to the climatic conditions of Greater Montreal, Laval, Longueuil, the North Shore, and the South Shore.


Why this FUJITSU model was the right choice for this installation in Saint-Constant

Heating Performance Adapted to Quebec Winters

In a room used daily as an office, thermal comfort must be constant. This FUJITSU ORION XLTH wall-mounted heat pump offers:

  • Effective heating down to −26 °C
  • Stable capacity even during prolonged cold spells
  • Inverter technology ensuring uniform temperature

In this specific case, the client previously used electric wall heating (visible in the photo), which led to high costs and inconsistent heat. The installation of this heat pump now allows for:

  • A significant reduction in energy bills
  • Faster temperature rise
  • Constant comfort without fluctuations

Quiet Operation Ideal for an Office

One of the essential criteria for this project was noise. Since the room is used for calls, audio recordings, and focused work, a nearly inaudible solution was required.

The FUJITSU ORION XLTH offers:

  • 23 dB(A) minimum indoors
  • Smooth airflow, without turbulence

Result: even during continuous operation, the heat pump does not disturb calls or recordings.


Technical Details of the Installation Carried Out by AirGreen

Optimal Positioning of the Indoor Unit

As seen in the image, the wall unit was installed high up, near the ceiling, in a strategic corner of the room. This choice is never left to chance.

Our objectives were:

  • Maximize air distribution throughout the room
  • Avoid obstacles (screen, microphone arm, furniture)
  • Minimize visual impact

Despite the confined space, we achieved a clean and balanced integration, with optimized airflow direction to avoid blowing directly onto the workstation.

Managing Space Constraints

The main challenge here was the proximity of the ceiling and the adjacent wall, which limits installation margins.

Our solutions:

  • Strict adherence to minimum clearances recommended by Fujitsu
  • Precise adjustment of the wall bracket
  • Millimeter-precise installation to avoid any vibration or noise

This type of configuration requires real expertise in residential HVAC installation, as improper positioning can affect:

  • Air circulation
  • Energy efficiency
  • Appliance durability

Refrigerant Piping Routing

The piping (1/4 – 3/8) was discreetly integrated, taking into account:

  • The wall structure
  • Interior aesthetics
  • Exterior access for the condenser unit

We also performed:

  • A complete vacuum pull
  • Pressure verification
  • Commissioning in compliance with standards

Energy Performance and Concrete Savings

Certified Efficiency

The FUJITSU ORION XLTH 12,000 BTU offers remarkable performance:

  • SEER2: 30.5
  • HSPF2: 12.7
  • ENERGY STAR® (cold climate) certification

This concretely means:

  • Less electricity consumed in summer
  • More economical heating in winter
  • Stable performance over several years

LogisVert Subsidy Available

For this project in Saint-Constant, the client is eligible for a LogisVert provincial subsidy of $1,200, which:

  • Reduces the initial cost
  • Accelerates the return on investment

At AirGreen, we always support our clients in these processes.


Advantages of R-32 Refrigerant in this Project

This installation uses R-32 gas, which offers several benefits:

  • Reduced environmental impact
  • Better thermal efficiency
  • Modern technology aligned with future standards

From a sustainability perspective, this is a wise choice for homeowners looking to modernize their HVAC system.


Customer Feedback After Installation

A few days after commissioning, the client confirmed several notable improvements:

  • Stable temperature even on cold nights
  • Total silence during calls and work
  • Immediate reduction in wall heater usage

The integrated Wi-Fi control also allows for:

  • Adjusting the temperature remotely
  • Programming cycles according to work schedules

AirGreen's Advice for This Type of Installation

To be prioritized

  • Install the unit high up for better distribution
  • Keep clearance around the unit
  • Clean filters regularly

To be avoided

  • Installing too close to the ceiling without respecting margins
  • Obstructing the air outlet with furniture
  • Neglecting maintenance

Why Choose AirGreen for Your HVAC Installation in Saint-Constant

At AirGreen, every installation is adapted to the client's reality, not standardized. In this project:

  • Complete analysis of the room and its use
  • Selection of a perfectly suited model
  • Precise installation despite constraints
  • Professional commissioning

We operate everywhere in Montreal, Laval, Longueuil, the North Shore, and the South Shore, with recognized expertise in Fujitsu wall-mounted heat pumps.


Final Result: Comfort, Efficiency, and Perfect Integration

This installation in Saint-Constant demonstrates that a well-chosen and well-installed wall-mounted heat pump can transform a workspace into a perfectly comfortable environment, summer and winter alike.

The FUJITSU ORION XLTH 12,000 BTU proves here to be a reliable, quiet, and durable solution, perfectly adapted to Quebec's climatic realities.
