Installation of a Fujitsu LZAH1 Wall-Mounted Heat Pump in Montreal
Discover how AirGreen installed the ultra-efficient Fujitsu LZAH1 Heat Pump in Montreal, delivering year-round comfort with whisper-quiet operation and energy savings.
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.
Transforming Comfort with the Fujitsu LZAH1: A Smart Choice for Any Home
When it comes to optimizing your home's climate control, the Fujitsu LZAH1 Wall-Mounted Heat Pump is in a class of its own. At AirGreen, we recently had the privilege of installing this sleek, efficient system in a stunning home located in the heart of Montreal. Not only does this 12,000 BTU mini split model deliver exceptional performance, but it also qualifies for the $1,200 LogisVert grant from Hydro-Québec, making it an affordable and eco-friendly upgrade.
Let us take you through the details of this exciting project and why the Fujitsu LZAH1 is a standout choice for homeowners in Montreal and beyond.
A Snapshot of the Installation
This particular project involved installing a Fujitsu LZAH1 Mini Split Heat Pump in a modern Montreal home. The homeowners wanted a system that could handle the city's icy winters, with temperatures dropping as low as -26°C, while also providing whisper-quiet cooling during the hot summer months. They were delighted to learn that this model offers an impressive 29.4 SEER efficiency rating and operates at indoor sound levels as low as 23 dB(A)—a barely perceptible hum.
Our expert technicians carefully mounted the indoor unit, measuring 38.44 x 9.44 x 11.06 inches, in a central location to maximize airflow and comfort. The outdoor condenser unit, designed with dimensions of 31.44 x 11.44 x 24.88 inches, was securely installed on a rooftop stand, ensuring it remains elevated and free from debris.
Why Choose the Fujitsu LZAH1?
Unmatched Efficiency and Comfort
The Fujitsu LZAH1 delivers a perfect blend of performance and energy savings. Its advanced inverter technology ensures consistent temperatures without the energy waste associated with traditional systems. Whether heating or cooling, this model provides year-round comfort while significantly lowering energy bills.
Ultra-Quiet Operation
At just 23 dB(A) for the indoor unit, the LZAH1 is quieter than a whisper. The outdoor unit is also remarkably quiet at 47 dB(A), allowing for undisturbed outdoor enjoyment.
Cold-Weather Champion
One of the highlights of the Fujitsu LZAH1 is its impressive heating capacity in extreme cold. Even at temperatures as low as -26°C, this heat pump keeps your home warm and cozy, making it a dependable choice for Montreal's harsh winters.
Our Approach to the Installation
Step 1: Consultation and Planning
Every great installation begins with understanding our clients' needs. The homeowners were particularly interested in the LogisVert grant, which we confirmed this model qualifies for, helping them save $1,200 upfront.
Step 2: Installing the Indoor Unit
We selected a central wall in the living space to mount the indoor unit, ensuring optimal air circulation. Its compact design integrates seamlessly with the home's modern aesthetic.
Step 3: Setting Up the Outdoor Unit
The outdoor condenser was installed on a secure rooftop stand, using high-quality piping (1/4 - 3/8 inches) and durable wiring. The setup ensures both efficiency and long-term reliability, even in harsh weather conditions.
Step 4: Testing and Optimization
Before handing over the system, our team conducted rigorous tests to ensure seamless operation. The WiFi connectivity feature was also activated, allowing the homeowners to control the system remotely for added convenience.

And 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.
