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.
The Silent Revolution: A Tale of HVAC Excellence
The Backstory: Out with the Old, In with the New
In the heart of Sainte-Julie, South Shore, a tale of transformation unfolded. A homeowner, tired of the constant hum and inefficiency of their old machine, yearned for silence and efficiency. The old machine, though still functional, had become a relic of the past, stopping its heating function at a mere -10°C and causing more noise than comfort. The time had come for an upgrade, and AirGreen was the chosen savior.
Choosing the Perfect Machine
The homeowner's requirements were clear:
- Silence: No more disturbances.
- Efficiency: A machine that could brave even the harshest of Canadian winters.
- Reputable Brand: Trust in the name and warranty.
- No New Holes: Use the existing infrastructure.
Enter the Gree Vireo Gen 3 Wall-Mounted Heat Pump. A marvel in the HVAC world, this machine boasts:
- Cooling Capacity: 12,000 BTU
- Heating Capacity: A staggering -30°C
- Efficiency: A commendable 25.0 SEER
- Sound Pressure Level: A whisper-quiet 27 dB(A) indoors and 52.0 dB(A) outdoors
- WiFi: Stay connected and control remotely
- Energy Star® Certification: For the eco-conscious
- Warranty: A solid 10-10-10 on Compressor, Parts, and Labor
The Installation Journey
Our team at AirGreen began with a thorough inspection of the old 1/4 - 1/2 pipes. Ensuring no cracks or leaks, we gave them a good wash and prepared for the installation. The homeowner watched with bated breath as we seamlessly replaced the old with the new, using the same exact pipes and ensuring no new holes were made in their pristine walls.
The result? A perfectly placed Gree Vireo Gen 3, ready to serve its purpose.
Grants and Savings
One of the cherries on top was the Federal Grant the model qualified for, allowing potential savings of $2,500 to $5,000. Additionally, a Provincial Grant of $385 made the deal even sweeter.

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.
