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.
Enhancing Comfort and Efficiency: Our Recent Gree Vireo GEN3 Installation in Montréal-Est
At AirGreen, we take pride in delivering tailored HVAC solutions to meet the unique needs of each home we service. Recently, our team completed the installation of a Gree Vireo GEN3 Wall-Mounted Heat Pump in Montréal-Est, providing the homeowner with a reliable, energy-efficient system designed for comfort year-round. Let’s dive into the details of this project and the remarkable features of the Gree Vireo GEN3.
The Story Behind This Installation
When the homeowner in Montréal-Est approached us, their goal was clear: they wanted a heating and cooling solution that was compact, efficient, and capable of performing well even in extreme cold. After assessing the property, we recommended the Gree Vireo GEN3, a model that combines style, functionality, and advanced technology. With its sleek design and 9,000 BTU capacity, it was the perfect choice for their needs.
This installation wasn’t just about placing a unit on the wall—it was about improving the homeowner's quality of life. With winter temperatures in Montréal-Est often plummeting below -30°C, the Vireo GEN3’s Ultra-Heat technology and superior 25.3 SEER efficiency make it a standout performer.
Why Choose the Gree Vireo GEN3?
The Gree Vireo GEN3 Wall-Mounted Heat Pump is a state-of-the-art HVAC system designed to deliver exceptional performance in both summer and winter. Here are some key highlights that make this unit a homeowner favorite:
- Heating Capacity: Functions efficiently in temperatures as low as -30°C.
- Cooling Capacity: 9,000 BTU to keep homes cool during the hottest summer days.
- Energy Star® Certified: Guarantees reduced energy consumption, making it an eco-friendly and cost-effective choice.
- WiFi-Enabled: Control your system remotely via your smartphone for convenience.
- Quiet Operation: Indoor sound levels range from a whisper-quiet 25 dB(A) to a maximum of 40 dB(A), ensuring peace in every room.
- Smart Features: Includes Turbo Mode, Smart Defrost, and I-Feel Technology, which optimizes comfort by sensing temperature at the remote control rather than at the unit.
Details of the Installation
Our professional installation process ensures every system operates at peak efficiency. Here’s a closer look at the technical aspects of this project:
- Interior Unit Dimensions: 32.5 x 7.75 x 11.5 inches
- Exterior Unit Dimensions: 33.38 x 12.63 x 23.5 inches
- Refrigerant: R-410A, an environmentally friendly and efficient cooling agent.
- Pipe Sizing: 1/4 - 3/8 inches for optimal refrigerant flow.
- Voltage: 220V, ensuring compatibility with most residential electrical systems.
To maximize performance and efficiency, we carefully positioned the interior unit for optimal airflow and unobstructed cooling and heating. The exterior unit was installed on a durable, vibration-resistant platform to minimize noise and ensure longevity.
The LogisVert Grant Advantage
One of the standout benefits of this installation is its eligibility for the $385 LogisVert Grant by Hydro-Québec. This grant is part of a provincial initiative to encourage energy-efficient home upgrades. By choosing the Gree Vireo GEN3, the homeowner not only invested in their comfort but also took advantage of valuable financial incentives.

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.
