A Seamless Transition to Supreme Comfort and Efficiency
A Tale of Transformation in Rosemère
In the serene locality of Rosemère on the North Shore, we at AirGreen recently had the pleasure of transforming an HVAC tale of despair into one of delight and efficiency. Our client, burdened by an obsolete, noise-generating, and inefficient heating system, reached out in hopes of a miraculous repair. However, the old machine was not just outdated but ran on the elusive R-22 Freon, making any repair attempt economically impractical.
The Gree Crossover: A Harmonious Solution
In the face of such HVAC adversity, we introduced our client to the Gree Crossover Wall-Mounted Heat Pump. This model is not just a heating and cooling powerhouse but a silent operator, ensuring comfort without the auditory compromise. With a cooling capacity of 12,000 BTU and the ability to provide heat in the chilling -30°C, the Crossover is a testament to Gree’s commitment to quality and innovation.
Key Features of the Gree Crossover:
- Whisper Quiet Operation: With an interior sound pressure level ranging between 27 to 43 dB(A), the Gree Crossover ensures your comfort isn’t accompanied by disruptive noise.
- Extended Warranty: A comprehensive 10-year warranty on compressor, parts, and labor, providing peace of mind for a decade.
- Energy Efficiency: Boasting a 25.0 SEER efficiency rating and Energy Star® certification, the Crossover is designed for optimal energy utilization.
- Wireless Connectivity: With included WiFi capabilities, controlling your comfort has never been easier.
- Robust Build: With dimensions meticulously crafted to fit existing setups, the Crossover is a seamless addition to your home.
Installation: A Symphony of Precision and Care
Our installation process in Rosemère was as smooth as the operation of the Gree Crossover itself. The client’s concerns about warranty and noise were alleviated with the introduction of the Crossover, but the installation process was where AirGreen truly shined.
Installation Highlights:
- Detailed Inspection: Our technicians meticulously inspected and cleaned the existing pipes, ensuring a flawless foundation for the new system.
- Professional Installation: With attention to every detail, the installation was executed professionally, adhering to the highest industry standards.
- Client Education: We empowered our client with the knowledge to maximize the efficiency and longevity of their new Gree Crossover.
Grants and Savings: The Icing on the Cake
The Gree Crossover doesn’t just bring comfort and silence to your home; it brings a wave of financial relief through Federal and Provincial Grants. With admissibility for a Federal Grant ranging from $2,500 to $5,000 and a Provincial Grant of $385, the initial investment in supreme comfort and efficiency is substantially alleviated.

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.
