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.

Built into the ceiling, it sends air out on four sides. Only the grille shows in the room.
Above the ceiling, there has to be enough height for the unit, its hangers and its connections, with access for service.
In cooling mode the cassette produces water. It leaves through a drain with the right slope, or through a pump when needed.
The lines and the cable reach the outside through an opening sealed against water, cold air and insects.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible.
The compressor and the fan. In heating mode it captures heat from the outdoor air and moves it inside.
It keeps the unit above accumulated snow, so it stays clear and defrost water can drain.
Embracing Efficiency with Gree: A Case Study of Advanced HVAC Solutions in Montreal
At AirGreen, our commitment to providing cutting-edge climate control solutions is exemplified by our latest installation: the Gree Ceiling Cassette Heat Pump. This project, carried out in the heart of Montreal, showcases not only our technical prowess but also our dedication to energy efficiency and discreet design.
The Project Overview
Our latest endeavor involved installing an 18,000 BTU Gree Ceiling Cassette Heat Pump, a model renowned for its exceptional cooling capacity and Energy Star certification. This installation was not just about enhancing indoor comfort but also about integrating a system that aligns with our client's energy efficiency goals and aesthetic values.
Why Choose the Gree Ceiling Cassette?
Efficient Performance: The Gree Ceiling Cassette is designed to provide maximum cooling and heating without the high energy costs associated with traditional HVAC systems. Its 18,000 BTU capacity makes it capable of maintaining a comfortable temperature in large spaces, while its Energy Star rating assures ongoing energy savings.
Sleek Design: Unlike bulky traditional units, this model boasts a compact design that fits seamlessly into the ceiling, preserving the room's aesthetics without sacrificing performance. The unit features a discreet grille that blends well with any interior decor.
Quiet Operation: With noise levels as low as 35 dB, the Gree Ceiling Cassette operates almost silently, making it ideal for environments where noise is a concern, such as bedrooms, libraries, and boardrooms.

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.
