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 Reliable Solution for Comfort in All Seasons
At AirGreen, we take pride in providing high-quality HVAC solutions tailored to the unique needs of each customer. Our latest project in Montréal-Nord involved the installation of a 9,000 BTU Gree Vireo GEN3 Wall-Mounted Heat Pump, a compact yet powerful mini split system designed to deliver year-round comfort. This installation not only highlights the versatility of the Vireo GEN3 but also underscores the trust that our clients place in our expertise.
The Client’s Vision: Efficiency Meets Comfort
When our client in Montréal-Nord reached out, they were seeking an efficient, quiet, and compact solution to maintain an optimal indoor climate regardless of the season. With Montréal’s challenging winters and humid summers, they needed a system that could handle extreme temperatures while being energy-efficient. The Gree Vireo GEN3 fit the bill perfectly, offering a blend of cutting-edge technology, sleek design, and reliable performance.
Why the Gree Vireo GEN3 Stands Out
The Gree Vireo GEN3 is a standout choice for anyone looking to balance functionality with style. Here’s why this system was perfect for our client:
- Cooling Capacity: 9,000 BTU, ideal for compact to medium-sized spaces.
- Heating Performance: Capable of operating efficiently at temperatures as low as -30°C, ensuring comfort even during Montréal’s harshest winters.
- Energy Efficiency: Boasting an impressive 25.3 SEER, this model ensures minimal energy consumption, saving money on electricity bills.
- WiFi Connectivity: Built-in WiFi allows the user to control the system remotely, offering unparalleled convenience.
- Quiet Operation: With an interior sound level ranging from 25 to 40 dB(A), the Vireo GEN3 is perfect for bedrooms and living spaces.
- Environmental Impact: Uses R-410A refrigerant, known for its eco-friendliness and efficiency.
The Installation Process: Precision and Expertise
Our team at AirGreen approached this installation with meticulous care, ensuring every aspect was optimized for performance and durability. Here’s a step-by-step breakdown:
- Initial Assessment: We conducted a thorough evaluation of the client’s home, focusing on the layout, insulation, and specific heating and cooling needs.
- Placement Optimization: The indoor unit was strategically installed in the living area to maximize airflow and comfort. Measuring 32.5 x 7.75 x 11.5 inches, it blends seamlessly with the room's décor.
- Outdoor Unit Installation: The exterior unit, measuring 33.38 x 12.63 x 23.5 inches, was mounted securely to ensure durability and noise minimization.
- Piping and Connections: Using durable 1/4 - 3/8-inch pipes, we ensured leak-proof connections for optimal refrigerant flow.
- System Configuration: The WiFi feature and remote controller were configured to suit the client’s preferences, enabling full control of temperature settings.
Eligible Grants: Making Comfort Affordable
One of the highlights of this installation is its eligibility for the LogisVert Grant by Hydro-Québec, providing a rebate of $385. This grant makes high-performance HVAC systems more accessible, encouraging energy-efficient upgrades across Québec.

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.
