A perfect installation for year-round comfort in Anjou
We recently completed an exciting project in Anjou, installing the Gree Charmo 19, an 18,000 BTU heat pump designed to handle Montreal’s fluctuating climate with ease. From sizzling summer heat to the frigid cold of a Quebec winter, this installation ensures our client will enjoy optimal indoor temperatures all year long.
Our team at AirGreen meticulously planned this project, ensuring a seamless installation that not only provides exceptional performance but also blends perfectly with the home’s aesthetics.
Why the Gree Charmo 19 is perfect for Anjou’s weather
One of the biggest challenges in Quebec is maintaining comfort during extreme temperatures. The Gree Charmo 19 solves this with its impressive 18,000 BTU cooling capacity and the ability to heat even in temperatures as low as -25°C. The versatility of this heat pump makes it an excellent choice for homes across Montreal, Laval, and beyond.
But it’s not just the power of the unit that stands out—it’s also about efficiency and comfort. With an efficiency rating of 17.5 SEER, the Gree Charmo 19 ensures that our customers are not only comfortable but also saving on energy costs.
A compact, elegant design to fit any space
At AirGreen, we understand the importance of combining functionality with design. The Gree Charmo 19 features sleek, compact dimensions, making it easy to integrate into any room without dominating the space. The indoor unit, measuring 37.13 x 9.69 x 13.13 inches, is discreet yet powerful, while the outdoor unit, with its dimensions of 31.63 x 13.88 x 21.88 inches, ensures minimal visual impact while providing maximum output. This unit is perfect for residential installations in compact spaces like the one we handled in Anjou.
Ultra-quiet operation for peaceful comfort
Noise is often a concern when installing heating and cooling systems, but the Gree Charmo 19 stands out for its quiet operation. Indoors, the sound pressure level is just 42 dB(A), while outdoors, it operates at 57 dB(A)—ensuring that our client in Anjou can enjoy peace and quiet alongside optimal temperature control. This level of noise reduction makes it a great choice for urban environments like Anjou, where noise can be a concern for both homeowners and their neighbors.
Cutting-edge technology for modern living
What really elevates the Gree Charmo 19 is its inverter technology. This innovative system ensures the unit adjusts its power consumption based on the cooling or heating needs of the space. Not only does this reduce energy waste, but it also helps prolong the lifespan of the unit.
On top of that, the built-in WiFi allows for seamless remote control via a smartphone app, compatible with Amazon Alexa and Google Home. Imagine coming home on a cold winter day and adjusting your home’s temperature while you’re still on your commute. Our client in Anjou loved this feature, and we’re sure many more of our customers will too!
Installation challenges and successes
Every installation has its unique challenges, and this project in Anjou was no different. One key aspect we needed to address was optimizing the location of the outdoor unit. Montreal winters can be harsh, and exposure to extreme weather can reduce a system’s efficiency. We strategically placed the outdoor unit to ensure it’s well-protected from the elements while maintaining proper airflow, which is crucial for the system's longevity.
We also ensured that all piping and wiring were properly installed to meet the unit’s requirements: 1/4-inch for the liquid line and 1/2-inch for the gas line. Our technicians adhered to AirGreen’s meticulous standards, making sure that everything was neatly installed without compromising the home’s appearance.
Government grants: making it more affordable
One of the most attractive benefits of the Gree Charmo 19 is its eligibility for the LogisVert grant from Hydro-Québec. This provincial grant offers up to $560 back to the homeowner, making the investment in this energy-efficient system even more appealing. While the Gree Charmo 19 isn’t eligible for the federal grant, the provincial rebate helps reduce the overall cost, making it a smart financial choice for homeowners.
Eco-friendly and efficient
As part of our commitment to sustainability, we’re thrilled to offer systems like the Gree Charmo 19 that use R-410A refrigerant, which has a lower environmental impact compared to older refrigerants. This not only helps reduce greenhouse gas emissions but also ensures compliance with modern environmental standards.
Extended warranty for peace of mind
At AirGreen, we believe in offering our clients the best value. That’s why the Gree Charmo 19 comes with an exceptional 12-year warranty on the compressor and parts. For added peace of mind, customers can opt for an extended 10-year warranty on parts, labor, and the compressor. Our client in Anjou took full advantage of this offer, ensuring that they’re protected for the long term.
Professional installation by AirGreen: A job well done
It’s not just the high-quality equipment that makes a difference—it’s also about who installs it. At AirGreen, we take pride in our professional, highly skilled technicians who understand the intricacies of modern HVAC systems. Our team followed all best practices, ensuring that the Gree Charmo 19 was installed flawlessly, providing the homeowner with reliable heating and cooling for years to come.
For this project in Anjou, our technicians carefully planned every step, from the placement of the units to the wiring and piping. We also took extra care to ensure the outdoor unit was installed at the optimal height to avoid issues during snowstorms, a common concern for homeowners in Quebec. The end result? A smooth, worry-free installation that exceeded our client’s expectations.
Final thoughts: Why choose the Gree Charmo 19?
In summary, the Gree Charmo 19 is an exceptional choice for homeowners looking to combine comfort, efficiency, and advanced technology. Its ability to handle Quebec’s extreme weather conditions while operating quietly and efficiently makes it a standout option for homes across Montreal, Laval, Longueuil, the South Shore, and the North Shore.
At AirGreen, we are proud to offer both the system and our installation expertise, ensuring that every customer receives the highest level of service. If you’re considering upgrading your home’s HVAC system, the Gree Charmo 19 could be the perfect fit for you.
The job tools
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.
How the job unfolds
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 we check on a job like this one
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.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
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.
Good habits, once the unit is in place

- 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.

The right pages, at the right time
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.
