Installation of a FUJITSU ORION XLTH+ 15,000 BTU Wall-Mounted Heat Pump in Town of Mount Royal
HVAC installation in Town of Mount Royal of a Fujitsu Orion XLTH+ 15,000 BTU heat pump. Extreme performance, energy efficiency, and professional installation by AirGreen.
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.
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.
An HVAC Installation Designed for the Reality of Ville Mont-Royal Homes
At AirGreen, every HVAC installation is adapted to the real constraints of the building and the Quebec climate. In Ville Mont-Royal, we recently installed a FUJITSU ORION XLTH+ 15,000 BTU wall-mounted heat pump, a system designed to provide stable heating comfort down to -30 °C and efficient air conditioning during increasingly hot summers.
This project involved a single-family home with a specific configuration: limited lateral space, an exposed foundation, and a clear need to preserve the exterior aesthetics while optimizing performance. The objective was twofold: to improve interior comfort and reduce reliance on electric baseboards.
Technical Challenges Encountered and Custom Solutions
Strategic Positioning of the Outdoor Unit
The outdoor unit was installed on robust wall brackets, elevated from the ground. This decision is never insignificant:
- Protection against snow accumulation in winter
- Better drainage management during defrost cycles
- Reduction of vibrations transmitted to the ground
In this specific case, the proximity of the wall and the confined space required millimeter-precise installation. Our technicians used reinforced brackets with shock absorbers to ensure stability and quiet operation.
Management of Refrigerant Lines and Aesthetics
In the photo, you can see a carefully installed black protective conduit to conceal the lines. This detail, often overlooked, makes all the difference:
- Protection against bad weather
- Increased durability of installations
- Professional aesthetic finish
The routing of the pipes was optimized to minimize energy losses while adhering to strict industry standards.
Secure Electrical Integration
The installation required connection to a dedicated 220 V circuit with a 20A capacity (MCA/MOP). Our refrigeration technicians performed:
- Electrical connection compliant with the code
- Installation of surge protectors
- Full system verification before commissioning
Why Choose the FUJITSU ORION XLTH+ 15,000 BTU?

- Guaranteed heating down to -30 °C
- Power at -15 °C: 18,400 BTU
- High COP at low temperatures
In an area like Ville Mont-Royal, where winters can be harsh, this type of performance is essential.
Superior Energy Efficiency
The FUJITSU ORION XLTH+ wall-mounted heat pump offers impressive performance:
- SEER2: 28.7
- HSPF2: 13.0
- ENERGY STAR® Cold Climate Certification
Result: significant reduction in energy costs, particularly when replacing traditional electric systems.
Advanced Inverter Technology
Unlike conventional systems, this heat pump continuously adjusts its power:
- Stable temperature without fluctuations
- Fewer start-up cycles
- Extended lifespan
In this installation in Ville Mont-Royal, the client immediately noticed more consistent comfort, especially in the main open area.
R-32 Refrigerant: Efficiency and Responsibility
The system uses R-32, a modern gas:
- Less environmental impact than R-410A
- Better thermal conductivity
- Superior performance
Our technicians performed a complete vacuum pull and rigorous leak tests to ensure optimal performance.
Complete Installation Process
Step 1: Analysis and Sizing
Before any installation, we evaluated:
- Area and layout of rooms
- Building insulation
- Orientation and wind exposure
The choice of the 15,000 BTU proved ideal for effectively covering the main space.
Step 2: Indoor Unit Installation
The wall-mounted unit was strategically positioned to:
- Maximize air diffusion
- Avoid dead zones
- Ensure uniform comfort
With a sound level as low as 26 dB(A), it is perfectly suited for residential environments.
Step 3: Outdoor Unit Installation
Solid wall mounting, precise alignment, drainage management: every detail was executed according to AirGreen standards.
Step 4: Commissioning and Testing
We performed:
- Pressure testing
- Performance verification
- System calibration
The client was immediately able to observe the quality of the air conditioning and heating.
Concrete Results for the Client
After installation, the benefits were immediate:
- Reduction in energy consumption
- Stable thermal comfort
- Remarkable system silence
- Smart control via integrated Wi-Fi
The client now uses their system for efficient heating in winter while maintaining a comfortable temperature in summer.
Practical Advice for Homeowners
Do Not Neglect the Positioning of the Outdoor Unit
Installation too low can lead to:
- Ice accumulation
- Drainage blockage
- Premature failures
Choose Appropriate Power
Incorrect sizing leads to:
- Overconsumption
- Irregular comfort
- Accelerated wear

The big day, step by step
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.

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.
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.
