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 Seamless HVAC Installation for Comfort and Efficiency
At AirGreen, we are committed to providing our clients with top-notch HVAC solutions that blend modern technology, energy efficiency, and reliable performance. Recently, we completed the installation of a Fujitsu RLXFWH 18,000 BTU wall-mounted heat pump at a beautiful residence on the South Shore, where the homeowners were looking for a more energy-efficient heating and cooling solution.
Understanding the Customer's Needs
The homeowners reached out to AirGreen with a clear objective: they wanted to replace their outdated HVAC system with something modern, efficient, and quiet. They also sought a solution that would work seamlessly with the unique layout of their home, which features intricate wooden accents and artistic ceiling designs, as shown in the pictures. Given the complexity of their living space, we knew we had to install a system that wouldn’t detract from the aesthetic appeal of their home while offering superior performance.
After assessing the property, we recommended the Fujitsu RLXFWH heat pump, which is known for its sleek design, energy efficiency, and ability to maintain comfortable indoor temperatures even during the harshest winters in Quebec.

The Fujitsu RLXFWH: A Perfect Fit
The Fujitsu RLXFWH 18,000 BTU model is an exceptional choice for homes of varying sizes. With a SEER rating of 20.0, this unit offers one of the highest energy efficiencies in the market, which means our client can look forward to significantly lower energy bills. The Energy Star® certification ensures that this unit meets stringent standards for energy conservation, making it a responsible choice for environmentally conscious homeowners.
The LogisVert Grant from Hydro-Québec was another key factor that made this model attractive to the homeowners. By choosing the Fujitsu RLXFWH, they qualified for a grant of $1,752, which helped offset the initial cost of installation.
Installation Challenges and Successes
The installation itself posed a few interesting challenges due to the home’s architectural features. Our skilled technicians had to be particularly careful while working around the intricate woodwork and the textured ceiling. The placement of the indoor unit was crucial to ensure optimal airflow without disrupting the aesthetics of the room.
We installed the wall-mounted unit centrally to ensure that it would efficiently distribute both cool and warm air throughout the living space. The piping for the unit was concealed to maintain the room's clean look, and we ensured that the electrical wiring was safely routed without being an eyesore. Our team used high-quality materials, including 3/8 - 5/8 pipes to ensure the unit would function at peak efficiency for years to come.
Technical Specifications and Performance
One of the standout features of the Fujitsu RLXFWH heat pump is its ability to operate even in extremely cold temperatures. This unit can maintain a heating capacity down to -26°C, making it a reliable option for the frigid Quebec winters.
Key Technical Features:
- Capacity: 18,000 BTU for both heating and cooling
- Voltage: 220V, providing robust performance
- Sound Levels: 28 dB(A) indoors and 50 dB(A) outdoors, ensuring a whisper-quiet operation
- Compressor Warranty: 10 years
- Parts Warranty: 10 years
- Labor Warranty: 10 years
We also installed the outdoor unit in a discreet location to ensure minimal disruption to the outdoor living area while still allowing for easy access for future maintenance.
Quiet and Comfortable Living
One of the homeowner’s top concerns was noise. They needed a unit that wouldn’t interrupt the peace and quiet they cherish in their home. The Fujitsu RLXFWH excels in this area with an indoor sound level as low as 28 dB(A), which is quieter than a library. Whether the family is enjoying dinner together or relaxing in the living room, they won’t be disturbed by the hum of an HVAC unit.
A Hassle-Free User Experience
The Fujitsu RLXFWH comes with a user-friendly remote control that allows the homeowner to adjust settings with ease. Whether they need to tweak the temperature, set a timer, or switch between heating and cooling, the remote offers complete control. The advanced inverter technology ensures that the heat pump only uses the energy it needs to maintain the desired temperature, reducing waste and further driving down energy costs.
Extended Warranty for Peace of Mind
We understand that a new HVAC system is a significant investment, which is why we were pleased to offer the homeowners an extended warranty covering 10 years on the compressor, parts, and labor. This comprehensive coverage gives them peace of mind knowing that their system is protected for the long haul.
Eco-Friendly Refrigerant: R-410A
Another advantage of the Fujitsu RLXFWH is its use of R-410A refrigerant, which is known for being environmentally friendly. Unlike older refrigerants, R-410A does not deplete the ozone layer, making it a sustainable choice for homeowners looking to reduce their environmental impact.

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.
