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.
Enhancing Comfort with Precision: The Gree Livo GEN4 Installation
When it comes to optimizing home comfort with high efficiency and sleek design, the Gree Livo GEN4 Wall-Mounted Heat Pump stands out as a prime choice for homeowners across Montreal, including the prestigious neighborhood of Outremont. AirGreen is proud to showcase this particular installation, which not only enhances the living space but does so with an attention to detail and dedication to quality that is unmatched in the HVAC industry.
Project Overview and Client Needs
Our latest project involved the installation of the Gree Livo GEN4, a sophisticated wall-mounted heat pump, in a charming Outremont residence. Known for its quiet operation and efficient performance, the Livo GEN4 was chosen to replace an outdated and less efficient system, providing the homeowners with a modern solution to their heating and cooling needs.
The homeowners sought a system that could offer both warmth during the harsh Montreal winters and cooling in the sultry summer months, all while being energy-efficient and minimally invasive in terms of space and noise. The Gree Livo GEN4, with its impressive 18.5 SEER efficiency and a heating capability down to -25 °C, was the perfect fit.
Installation Specifics and Challenges
The installation of the Gree Livo GEN4 at this Outremont home required meticulous planning and execution to ensure optimal performance and aesthetic harmony with the home’s interior. The sleek indoor unit was mounted high on a hallway wall, chosen for its central location to maximize air distribution throughout the home. This positioning allows for efficient air flow in living spaces, ensuring comfort in every corner.
A critical component of the installation was integrating a small, compact, and silent drain pump directly attached to the indoor unit. This pump is essential for removing condensation effectively, especially crucial in a humid climate. Its silent operation is key to maintaining the tranquility of the home environment.
Technical Advancements and Features
The Gree Livo GEN4 is a testament to technological advancement in the field of HVAC systems. Equipped with a G10 Inverter technology, it adjusts power usage dynamically based on the need, which significantly reduces energy consumption while maintaining comfort levels. Its Wi-Fi connectivity enhances user convenience, allowing homeowners to control their indoor climate with the touch of a button from their smartphones.
Design Integration
The unit's design complements the elegant interior of the Outremont home. Measuring 32.88 x 7.88 x 10.88 inches for the indoor unit, it blends seamlessly into the background, maintaining the aesthetic integrity of the home’s design. The outdoor unit, compact and unobtrusive, does not detract from the home’s exterior appearance.
Environmental Impact and Energy Savings
By choosing the Gree Livo GEN4, the homeowners benefit from lower energy bills due to the unit’s high energy efficiency. Additionally, this model qualifies for a $350 LogisVert Grant by Hydro-Québec, reflecting its status as an environmentally friendly choice.
Customer Satisfaction and Aftercare
Post-installation, the homeowners expressed immense satisfaction with the comfort improvements and the service provided by AirGreen. They were particularly impressed by the unit's quiet operation, noting that it did not interrupt daily activities or sleep, even when running at full capacity during the night.
AirGreen's commitment extends beyond installation. With a 12-year warranty on parts and compressor and our dedicated customer service, we ensure that our clients continue to enjoy optimal comfort and performance from their Gree Livo GEN4 for years to come.
Conclusion: A Testament to Quality and Comfort
The Gree Livo GEN4 installation in Outremont by AirGreen is a perfect example of how advanced technology, when integrated with expert service, can transform a living space. It underscores our commitment to providing energy-efficient, reliable, and aesthetically pleasing HVAC solutions that meet the diverse needs of our clients in Montreal, Laval, Longueuil, North Shore, and South Shore.

And 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.
