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 Client’s Needs: Addressing Comfort and Efficiency
Our client in Delson was looking for an HVAC solution to keep their home cozy during Quebec’s harsh winters, while also ensuring relief during humid summers. They desired a system that offered reliability, energy efficiency, and a quiet operation. After a thorough consultation and assessment of their living space, we recommended the GREE LIVO GEN4 12,000 BTU ductless mini split system.

The GREE LIVO GEN4 is not your average heat pump. Engineered for both performance and convenience, this system offers a wide range of features that make it a standout choice for homeowners in Delson and beyond. Here’s what makes this model exceptional:
- Energy Efficiency: With an 18.5 SEER rating, the LIVO GEN4 delivers excellent efficiency, helping reduce energy bills without compromising comfort.

Highlights of the Installation Process
Our team arrived promptly at the Delson home with all necessary tools and materials. The installation site had been prepped, and our technicians ensured minimal disruption to the homeowner’s routine. Here’s a step-by-step overview of the process:
Site Preparation
We began by assessing the indoor and outdoor locations for the heat pump. The client opted for a discreet yet functional placement for the indoor unit, while the outdoor unit was installed in a spot that optimized airflow and minimized noise.
Precision Installation
Using the manufacturer’s guidelines and our expert knowledge, we securely mounted the indoor unit (measuring 32.88 x 7.88 x 10.88 inches) in the client’s living room. This placement ensures even cooling and heating distribution. The outdoor unit (dimensions 28.81 x 13 x 21.88 inches) was installed on a sturdy base to withstand Quebec’s winter conditions.
Seamless Piping and Electrical Work
To maintain the aesthetic appeal of the client’s home, we carefully routed the 1/4 - 3/8 piping along the walls using protective covers. The unit was connected to a 220 V power supply, and all connections were thoroughly tested to ensure safety and functionality.
System Testing and Client Walkthrough
Before completing the job, we ran extensive tests to verify the system's cooling and heating capacities. We also walked the client through the WiFi setup and explained how to adjust settings for maximum comfort.
Environmental and Financial Benefits
The GREE LIVO GEN4 installed in Delson qualifies for a $340 LogisVert Grant by Hydro-Québec. This incentive not only reduces the upfront cost but also encourages homeowners to invest in energy-efficient technologies. Moreover, the use of R-410A refrigerant ensures that the system operates with a reduced environmental impact compared to older models.

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.
