Installation of a FUJITSU ORION XLTH KZAH R-32 12,000 BTU wall-mounted heat pump in Beaconsfield
Professional installation of a FUJITSU ORION XLTH 12,000 BTU wall-mounted heat pump in Beaconsfield. Performance, silence, and energy savings at the heart of the AirGreen project.
Take a tour of the installation
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.

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.
A High-End HVAC Installation Perfectly Integrated into a Beaconsfield Residence
At AirGreen, every HVAC installation project is unique. This recent installation of a FUJITSU ORION XLTH 12,000 BTU wall-mounted heat pump in Beaconsfield, in the west of Montreal, is an excellent example. The client wanted a reliable solution to face Quebec winters while enjoying optimal comfort during the summer.
From our first visit, several elements caught our attention: a main room with a standard ceiling, direct proximity to a side window, and a significant aesthetic constraint related to the interior finish. The goal was clear: integrate a high-performance, discreet wall-mounted heat pump, perfectly aligned with the existing architecture.
Challenges Encountered and Tailored Technical Solutions
Strategic Positioning of the Indoor Unit
As can be seen from the completed installation, the indoor unit was installed high up, near the ceiling, to optimize air distribution. This positioning allows for:
- Better air circulation throughout the room
- Uniform heat distribution in winter
- Effective air conditioning without direct drafts
However, this type of installation requires extreme precision. We had to adjust the position to avoid ceiling moldings and respect the clearances recommended by the manufacturer.
Piping Management and Aesthetics
The client insisted on a clean visual appearance. We therefore used:
- Discreet pipe covers perfectly aligned with the wall
- An optimized wall outlet to minimize visual impact
- Careful integration near the window to reduce visible length
In this project, standard 1/4 - 3/8 piping was used, with a total length of less than 15 feet, which is included in our standard installation at AirGreen.
Drainage Verification and Level Management
As with all our installations, we performed an essential practical test: pouring water into the system to confirm proper drainage. This simple but effective method ensures that:
- Water drains correctly
- No backflow or accumulation occurs
- The system is ready to operate without risk
This test is particularly important in wall-mounted installations where the slope can influence condensate evacuation.
Why Choose the FUJITSU ORION XLTH 12,000 BTU?
Exceptional Heating Performance
In a region like Beaconsfield, where winter temperatures can drop very low, this model stands out for:
- Heating capacity down to -26°C
- Impressive power even at -15°C (16,600 BTU)
- Inverter technology allowing constant modulation
Result: stable thermal comfort, even during periods of extreme cold.
Remarkable Energy Efficiency
This heat pump offers:
- SEER2: 30.5 (very efficient cooling)
- HSPF2: 12.7 (excellent heating performance)
- ENERGY STAR® Cold Climate certification
For the client, this means:
- Significant savings on electricity bills
- Reduced reliance on electric baseboard heaters
- A profitable long-term investment
R-32 Refrigerant: A Modern Choice
The system uses R-32 gas, which offers:
- Better energy efficiency
- Reduced environmental impact
- Compliance with new ecological standards
A Quiet Installation Adapted to Daily Life
The client also wanted a discreet appliance. With:
- 23 dB(A) indoors
- 47 dB(A) outdoors
The heat pump is practically inaudible in a residential environment. This is particularly important in quiet neighborhoods like Beaconsfield.
Technical Details of the Installation
Here are the key specifications of the installed system:
- Indoor model: ASUH12KZAS
- Outdoor model: AOUH12KZAH1
- Capacity: 12,000 BTU
- Voltage: 220V
- Piping: 1/4 - 3/8
- WiFi: Included
- Indoor sound level: 23 to 44 dB(A)
The complete installation was carried out in a single day by our team of certified refrigeration technicians.
LogisVert Subsidy: A Tangible Advantage
This project is eligible for the LogisVert subsidy of $1,200. This allows for:
- Significantly reducing the initial cost
- Accelerating the return on investment
- Encouraging the adoption of energy-efficient solutions
At AirGreen, we always support our clients in these endeavors to simplify the process.
Mistakes to Avoid During a Wall-Mounted Heat Pump Installation
Throughout this project, several essential points emerged:
Incorrect Unit Positioning
Installing the unit too low or improperly oriented can:
- Reduce efficiency
- Create cold or hot spots
- Increase energy consumption
Neglecting Drainage
Poorly designed drainage can lead to:
- Water leaks
- Wall damage
- Loss of performance
Underestimating the Importance of Installation
Even the best heat pump loses efficiency if:
- Vacuum pulling is poorly done
- Refrigerant charge is not adjusted
- Connections are approximate
Client Feedback After Installation
After a few days of use, the client confirmed to us:
- A stable temperature throughout the room
- Very quiet operation
- A noticeable reduction in electric baseboard heater use
This type of feedback accurately reflects our goal at AirGreen: to offer lasting and measurable comfort.

What would it look like 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.

Your own project, step by step
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
