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.
Bringing Energy Efficiency and Comfort to a Beautiful Home in Outremont
At AirGreen, we specialize in top-tier HVAC installations across Montreal, Laval, Longueuil, the North Shore, and the South Shore. Recently, we completed the installation of a Fujitsu LZAH1 12,000 BTU Wall-Mounted Heat Pump in a beautiful home located in Outremont, Montreal. This project was particularly exciting for us due to the client's desire to not only improve their home's comfort but also to maximize energy efficiency while benefiting from local grants. Let’s dive into the unique aspects of this installation and why the Fujitsu LZAH1 was the perfect choice for this residence.
Why the Fujitsu LZAH1 is the Ideal Heat Pump for Montreal Winters
The Fujitsu LZAH1 model isn't just another wall-mounted heat pump—it's designed to excel in both heating and cooling, making it perfectly suited for Montreal's unpredictable climate. The unit offers exceptional heating capabilities even in extreme low temperatures, continuing to work efficiently down to -26°C. With this kind of reliability, the homeowner can rest assured that their indoor environment will remain warm and comfortable, regardless of how cold Montreal’s winters get.

Unbeatable Energy Efficiency with 29.4 SEER
One of the standout features of this Fujitsu LZAH1 12,000 BTU model is its remarkable 29.4 SEER (Seasonal Energy Efficiency Ratio). This ensures that the homeowner benefits from lower energy consumption, leading to reduced utility bills. It’s no wonder the machine qualifies for the LogisVert Grant by Hydro-Québec, offering the owner a $1,200 rebate for choosing an energy-efficient solution.
Professional Installation with Expert Care
The installation took place in a classic Montreal home in Outremont, a neighborhood known for its blend of historical architecture and modern interiors. This provided a unique challenge for our team as we had to ensure the heat pump integrated seamlessly into the home’s aesthetic while maintaining its high performance.
Key Features of the Installation:
- Brand: Fujitsu
- Model: LZAH1 12,000 BTU
- Energy Star® certified
- AHRI-certified with an AHRI number of 206597211
- Piping Dimensions: 1/4 - 3/8

A Backstory: Why the Customer Chose AirGreen
The homeowner initially contacted us after conducting thorough research into several HVAC companies in the area. Their primary concerns were finding a system that would not disrupt the architectural integrity of their home and a company that could ensure reliable service and ongoing support. After discussing the project with our experts, it was clear that the Fujitsu LZAH1 was the ideal match for both their technical and aesthetic needs.
Additionally, the client was eager to take advantage of Hydro-Québec’s LogisVert grant program, which incentivizes homeowners to adopt more energy-efficient solutions. With the $1,200 grant, the Fujitsu LZAH1 became even more cost-effective, and our team worked closely with the homeowner to make sure all necessary paperwork was submitted on time.
Why the Fujitsu LZAH1 is Perfect for Homes in Montreal
Superior Heating Performance at -26°C
One of the critical factors in this decision was the Fujitsu LZAH1’s ability to perform in extremely low temperatures. This is essential in cities like Montreal, where winters are harsh, and maintaining warmth is crucial. With a heating capacity that doesn’t drop even in frigid conditions, the Fujitsu LZAH1 provides consistent comfort, keeping the home cozy no matter how cold it gets outside.
Whisper-Quiet Operation
Another key selling point for the homeowner was the whisper-quiet operation of the unit. With a sound pressure level as low as 23 dB indoors and 47 dB outdoors, this unit operates almost silently. For the residents of this historic home, the idea of a quiet, unobtrusive system was particularly appealing as it ensured that their day-to-day lives wouldn't be disrupted by a noisy HVAC system.
Compact Yet Powerful Design
The Fujitsu LZAH1 also stands out for its sleek, compact design. Despite its powerful performance, the unit fits seamlessly into small spaces, making it an excellent choice for older homes like those found in Outremont. The indoor unit’s dimensions (38.44 x 9.44 x 11.06 inches) allowed us to install it in a central location without it becoming an eyesore or taking up unnecessary space.

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.

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.
