Installation of a Fujitsu RLXFZH DoubleZone Heat Pump in Le Sud-Ouest
Efficient Comfort Delivered in Record Time – A New Installation by AirGreen
At AirGreen, we take pride in delivering the finest HVAC solutions across Montreal, Laval, Longueuil, and both the North and South Shores. Our recent installation in Le Sud-Ouest showcases our commitment to providing tailored heating and cooling systems that meet the unique needs of every household. With this project, we installed a Fujitsu RLXFZH DoubleZone Heat Pump, ensuring efficient, reliable comfort in even the harshest climates. Here’s how we made it happen.
The Challenge: Extreme Climate, Demanding Needs
Our client in Le Sud-Ouest had specific requirements for their home: they needed a system that could provide cooling during Montreal’s warm summers and still operate efficiently during the frigid winter months, where temperatures can drop well below freezing. Energy efficiency, cost savings, and a fast, non-invasive installation were the top priorities. We knew that the Fujitsu RLXFZH DoubleZone Heat Pump was the perfect fit for this scenario, and our team was excited to take on the challenge.
The Fujitsu RLXFZH DoubleZone Heat Pump: A Technical Powerhouse
What makes the Fujitsu RLXFZH DoubleZone stand out? Let’s dive into the details:
-
Compressor Capacity: This system boasts an impressive 36,000 BTU compressor. This means the heat pump can handle the heating and cooling of large areas, making it ideal for homes with varying climate control needs.
-
Independent Zones: The DoubleZone functionality allows for two distinct zones with independent temperature controls. In this installation, we equipped one zone with a 12,000 BTU indoor unit and another with a 24,000 BTU indoor unit. This setup allows our client to heat or cool specific areas based on their preference—whether it's the living room, bedroom, or any other zone.
-
Energy Star Certified: The RLXFZH model is Energy Star® certified, ensuring optimal energy efficiency. With 20.0 SEER (Seasonal Energy Efficiency Ratio), this system is designed to minimize energy consumption while maximizing comfort—ultimately translating into significant savings on electricity bills.
-
Extreme Cold Climate Performance: This heat pump can continue providing heat even at an astounding -26°C! For those living in Montreal, where winter nights can get bone-chilling, this feature is essential.
The Installation: Efficiency Meets Precision
When it comes to HVAC installations, we don’t just meet expectations; we exceed them. The installation of this Fujitsu RLXFZH DoubleZone Heat Pump was completed within a single day, minimizing any disruption to the client’s routine. Our team of expert technicians began with the outdoor compressor unit, carefully placing it in a discrete location outside the client’s home. Measuring 39.31 x 14.56 x 38.19 inches, the outdoor unit fit perfectly in the allotted space while ensuring easy access for future maintenance.
We followed up by installing the indoor units—one 12,000 BTU unit in the client’s bedroom and a 24,000 BTU unit in the living area. This setup allows for individualized climate control, offering the client maximum flexibility in managing their indoor environment. Whether they need extra warmth in the living room during gatherings or cooler temperatures in the bedroom during sleep, this system handles it all seamlessly.
Each indoor unit was mounted on the wall with precision, making sure to maintain an aesthetically pleasing appearance while optimizing airflow. Once mounted, our team tested the entire system to ensure everything functioned flawlessly.
The Benefits: Why Our Client Chose the Fujitsu RLXFZH DoubleZone Heat Pump
There are many reasons why this particular model of heat pump is gaining popularity across Montreal, Laval, and beyond. Here’s why our client was thrilled with their choice:
1. Cost Savings with LogisVert Grant
Not only does the Fujitsu RLXFZH DoubleZone offer fantastic energy efficiency, but it is also eligible for the LogisVert Grant by Hydro-Québec. Our client was able to receive a generous $2,568 rebate, making the investment even more attractive.
2. Quiet Operation
With an exterior sound pressure level of only 55 dB(A), the system is one of the quietest on the market. This was an important factor for our client, who valued peace and quiet at home. Now, they can enjoy unparalleled comfort without the disruptive noise associated with traditional systems.
3. Long-Term Reliability
This heat pump comes with an extended warranty covering the compressor, parts, and labor for 10 years. This warranty gives the client peace of mind, knowing they’re protected against potential issues for the next decade.

The job tools
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.
How the job unfolds
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.
Remote, modes, filters: we show you the essentials before we leave.

What we check on a job like this one
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.
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.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
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.
The right pages, at the right time
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.
