The Art of Mastering Space: A Unique Story of Heat Pump Installation
When it comes to heating and cooling solutions in Montreal's modern urban landscape, the challenge is not just selecting the right equipment; it's about seamlessly integrating technology into the lives and spaces of our clients. Our latest project in Ahuntsic-Cartierville highlights not only our expertise in installing a Gree Livo Gen4 heat pump but also our commitment to innovative solutions that respect our clients' space needs and lifestyles.
Understanding the Client's Vision
At the heart of our project was a client with a clear vision: to keep their driveway spacious while ensuring their home remains a haven of comfort, no matter the season. Installing a Gree Livo Gen4 18,000 BTU heat pump met these needs and more. But the path to realizing this vision was filled with unique challenges and innovative solutions.
Innovative Installation Techniques
High Placement of the Compressor
One of the most striking aspects of this installation was the decision to mount the compressor unit high on the exterior wall. This strategic placement was key to preserving the precious driveway space, a concern for many homeowners in densely populated urban areas like Montreal. Achieving this required meticulous planning and execution, balancing technical requirements with aesthetic considerations.
Concealing the Indoor Unit and Piping
The indoor unit was installed 30 feet from its outdoor counterpart, demonstrating our team's ability to navigate complex installations. Our technicians skillfully concealed the connecting piping within the wall, ensuring the interior aesthetics remained intact. This attention to detail is what sets AirGreen apart in the HVAC industry.
Proximity to the Electrical Panel: An Efficiency Advantage
The proximity of the electrical panel to the compressor significantly simplified the installation process. This not only made installation easier but also allowed us to offer a better price to our client. Efficiency in installation translates to savings for our clients, a principle we cherish at AirGreen.
Gree Livo Gen4: A Model of Efficiency and Comfort
The Gree Livo Gen4 is renowned for its heating capacity even at temperatures as low as -25°C, making it ideal for Montreal's harsh winters. With a SEER rating of 18.5 and a low noise level, it ensures efficient and quiet operation. The inclusion of WiFi offers convenience and smart control, a feature increasingly sought after by homeowners.
Key Features at a Glance
- Heating Capacity: Efficient operation at temperatures down to -25°C

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.
