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.
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.
A Unique Approach to Comfort in Senneville: The AirGreen Experience
The Challenge: A Non-Traditional Installation
In the quaint village of Senneville, an extraordinary installation story unfolds, spotlighting AirGreen's expertise and innovative approach to HVAC solutions. Recently, we embarked on a particularly unique project involving a Gree Crossover ductless heat pump that not only showcases our technical prowess but also our commitment to tailored client satisfaction.
The Site: A Spacious Garage Awaits
Our journey began in a large garage with ample space, owned by a customer with a clear vision. Unlike typical installations where the outdoor unit is placed outside, this scenario posed a creative challenge: mounting the outdoor unit inside the garage. This unusual request was seamlessly accommodated thanks to the proximity of the compressor—merely 10 feet from the electrical panel, ensuring a smooth and efficient setup.
Installation Highlights: Precision and Professionalism
- Close Proximity: The outdoor and indoor units were installed just 15 feet apart, simplifying the process and reducing the need for extensive materials.
- Significant Savings: The minimal material requirement allowed us to offer a significant discount, enhancing customer delight.
- Quiet Efficiency: The system operates with such silence that it becomes easy to forget it's there—until you feel the comfortable temperatures it maintains.
- Impressive Warranty: The 10-year comprehensive warranty on the compressor, parts, and labor by Gree Canada stands testament to the quality and reliability promised with this installation.
The Gree Crossover: A Technological Marvel
Gree's Crossover model is not just another ductless heat pump; it's a beacon of efficiency and innovation. With a 25.0 SEER rating and multiple high-end features, this system represents the pinnacle of climate control technology.
Key Features of the Gree Crossover:
- G10 Inverter Technology: Optimizes performance for energy efficiency and user comfort.
- Smart Connectivity: Includes WiFi capabilities and compatibility with the GREE+ app for effortless control.
- Eco-friendly Design: Utilizes R-410A refrigerant, which is known for its lower environmental impact.
- User-Centric Operations: Features like the adjustable LED display, multi-speed fan, and washable dust filters prioritize convenience and maintenance ease.
Customer Feedback: Beyond Satisfaction
The response from our client was overwhelmingly positive. The efficiency and silence of the system, coupled with the financial benefits of the LogisVert Program by Hydro-Québec, which provided a $385 grant, left the client more than satisfied. They praised our turnkey installation process and the peace of mind that comes with a decade-long warranty on all fronts.

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.
