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 Seamless Integration into the Office Environment
At AirGreen, we pride ourselves on delivering top-notch HVAC services tailored to the unique needs of our clients. Our recent installation in Dorval, Montreal, is a testament to our commitment to excellence and our ability to understand and cater to the specific requirements of our customers.
Why the Gree Sapphire Wall-Mounted Heat Pump?
When it comes to ensuring a comfortable office environment, the right choice of HVAC equipment is crucial. The Gree Sapphire Wall-Mounted Heat Pump was the perfect fit for this particular office setting in Dorval for several reasons:
-
Silent Operation: In an office, the last thing anyone wants is a noisy machine disrupting concentration. With an interior sound pressure level of just 27 dB(A) at its quietest, the Gree Sapphire ensures a peaceful work environment.
-
Efficiency: With a cooling capacity of 24,000 BTU and an impressive efficiency rating of 21.5 SEER, this machine is designed to deliver optimal performance without inflating energy bills.

The Installation Day: A Story to Remember
Our team arrived at the office building in Dorval, ready to embark on what was categorized as an "easy" installation. But what made this installation truly memorable was the warmth and hospitality of the office staff. From the moment we stepped in, it was evident that this wasn't just another installation job; it was an experience.
Finding the perfect spot for the heat pump was crucial. We needed a location that ensured efficient airflow without causing any disturbances. After a thorough assessment, we identified the ideal spot that would guarantee year-round comfort for the entire office.
As our technicians worked diligently, they were met with curious glances, friendly chats, and even an occasional coffee offer from the office staff. The atmosphere was buzzing with anticipation. And when the installation was complete, the gratitude was palpable. The office now had a state-of-the-art, silent, and efficient heat pump that would ensure a comfortable environment all year long.

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.
