A Discreet and Efficient Installation in a Saint-Lambert Residence
In many residences on the South Shore, the main challenge is not just to efficiently heat or cool a space. It is also necessary to preserve the interior aesthetics, limit noise, and optimize every available square foot. This is precisely the context we encountered during this recent installation carried out by AirGreen in Saint-Lambert.
Our client wanted to replace an old air conditioning system that had become noisy and energy-inefficient. The objective was clear: achieve better four-season comfort with a modern, compact, and quiet wall-mounted heat pump, without altering the clean appearance of the room.
After analyzing the needs and inspecting the premises, our team recommended the GREE CHARMO R32, a model particularly appreciated for residential projects requiring excellent performance in a discreet format.
Upon arrival on site, several technical constraints were evident. The available wall was relatively narrow, located near a door frame, with limited clearance between the ceiling and the planned location for the indoor unit. This type of installation requires significant precision to meet air circulation standards and ensure optimal long-term operation.
The image of this installation clearly shows the final result: a perfectly aligned indoor unit, installed near the ceiling to maximize air diffusion, while maintaining a sober appearance integrated into the space.
Why the GREE CHARMO R32 was the right choice
The CHARMO R32 series from GREE represents an excellent balance between energy efficiency, comfort, and reasonable installation cost.
For this Saint-Lambert residence, several factors influenced our recommendation:
- Quiet operation
- Compact design
- Efficient heating down to -25 °C
- Integrated Wi-Fi control
- More ecological R32 refrigerant
- Good energy efficiency for the Quebec climate
The announced performance for this series reaches up to 20 SEER2 and 8.8 HSPF2 depending on the chosen configuration.
In this specific project, the installed configuration was ideal for efficiently air conditioning the main area while maintaining excellent heating capacity during the cold periods typical of Montérégie.
A Clean HVAC Installation Despite Wall Constraints
Installations in confined spaces require more than just simple wall mounting. At AirGreen, we place great importance on the visual finish and mechanical reliability of the system.
In this Saint-Lambert residence, we had to:
- Precisely adjust the wall plate location
- Verify the drainage angle of the condensation pipe
- Optimize the routing of refrigerant lines
- Minimize cabling visibility
- Ensure sufficient clearance for future maintenance
The owner wanted to avoid bulky installations often visible in some poorly executed residential projects. We therefore used a carefully planned duct route to maintain a clean appearance.
The final result gives the impression that the machine has always been part of the house.
Comfort Felt Immediately After Startup
Once the installation was completed, we performed the usual power-up and performance checks:
- System pressure
- Discharge air temperature
- Electronic communication
- Condensate drainage
- Heating and cooling mode calibration
The client immediately noticed the difference in noise level. Compared to their old system, the GREE CHARMO R32 heat pump operates at a very low sound level, especially in reduced ventilation mode.
Some configurations of the series show indoor sound levels as low as 32 dB(A).
In a living room or bedroom, this feature quickly becomes a major advantage.
What Owners in Montreal and the South Shore Need to Know Before Installing a GREE Mini-Split
Through our many wall-mounted heat pump, mini-split air conditioner, and HVAC system projects in Montreal, Laval, Longueuil, on the North Shore and the South Shore, we often observe the same errors when choosing an HVAC system.
Common mistake: choosing solely based on price
Many homeowners focus solely on the initial cost of the machine. However, an ill-suited system can lead to:
- Excessive electricity consumption
- Inefficient operating cycles
- Thermal discomfort
- Premature wear
- Higher noise level
In the case of this installation in Saint-Lambert, we took the time to evaluate:
- The actual surface area
- The building's insulation
- Sun exposure
- Natural air circulation
- The client's heating habits
It is this approach that ensures a truly efficient installation.
R32 Refrigerant: A Concrete Advantage
The GREE CHARMO R32 series uses a newer refrigerant than many older systems still present in Quebec.
R32 notably offers:
- Better energy efficiency
- Reduced environmental impact
- Improved thermal performance
- Lower refrigerant charge in many applications
GREE's technical documents also highlight the efficiency gains associated with R32 compared to previous generations.
For homeowners who want to modernize their HVAC system without installing very expensive high-end equipment, this series often represents an excellent compromise.
A Heat Pump Adapted to Quebec Winters
In Saint-Lambert, as throughout Greater Montreal, simple air conditioning is no longer enough. Customers are now looking for systems capable of providing stable heating for a large part of the winter.
The GREE CHARMO R32 offers heating operation down to -25 °C according to manufacturer specifications.
This allows for:
- Reducing the use of primary heating
- Improving comfort in certain cold areas
- Lowering energy costs
- Achieving a more stable temperature
In this Saint-Lambert residence, the client was precisely looking for a solution capable of supporting the existing heating without skyrocketing the electricity bill.
A Fast, But Never Rushed, Installation
This project was completed efficiently in a single day. However, speed never means improvisation at AirGreen.
Each installation includes:
- Detailed prior inspection
- Electrical validation
- Surface protection
- Leak test
- Professional vacuuming
- Full function verification
It's often in the invisible details that one recognizes the quality of an HVAC installation.
This type of project is ideal for:
- Condos
- Small houses
- Open spaces
- Home offices
- Main rooms
- Bedrooms
The compactness of the indoor unit observed in this Saint-Lambert installation clearly demonstrates why modern mini-split models are gaining so much popularity in Greater Montreal.
Why South Shore Customers Choose AirGreen
Our teams carry out installations of wall-mounted heat pumps, mini-split air conditioners, and HVAC systems throughout Montreal, Laval, Longueuil, on the North Shore, and the South Shore.
What distinguishes our approach:
- Advice adapted to the actual building
