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 Journey Through the Installation of a High-Efficiency Gree DoubleZone Heat Pump
In the heart of Kirkland, Montreal, an exceptional HVAC transformation took place that not only showcases the prowess of AirGreen, your trusted HVAC company, but also highlights the superior features and benefits of the Gree Multi GEN2 DoubleZone Heat Pump. This installation story is not just about upgrading a home's heating and cooling system; it's about how AirGreen ensures unparalleled comfort and efficiency for every customer, with a touch of innovation and a sprinkle of creativity.
Why This Installation Stands Out
Crafting Comfort in Every Corner:
The installation in Kirkland was anything but ordinary. The challenge was to install a Gree Multi GEN2 DoubleZone Heat Pump, known for its robust 36,000 BTU compressor and dual 18,000 BTU indoor units. The medium difficulty of this project was met with meticulous planning and expert execution, ensuring that every step was taken with precision and care.
Strategic Placement for Maximizing Space:
One of the critical requirements from our client was the strategic placement of the compressor. Elevating it not only maximized the backyard space but also demonstrated our capability to tailor solutions to specific customer needs. This bespoke approach is what sets AirGreen apart, ensuring each installation is as unique as the individuals we serve.
Innovative Solutions for Complex Challenges:
The installation journey took an interesting turn when addressing the placement of the indoor units. With one unit needing to be installed at the opposite end of the house, our team navigated through two bedrooms and a bathroom, showcasing our commitment to overcoming obstacles with innovative solutions.
A Masterful Finish:
Our collaboration with a master plasterer was the cherry on top, ensuring that after the heat pump installation, every pipe and wire was meticulously concealed. The result? A flawless finish that speaks volumes of our attention to detail and our dedication to not just meeting, but exceeding, our client’s expectations.

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.
Remote, modes, filters: we show you the essentials before we leave.

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.
