The article, chapter by chapter
At AirGreen, we pride ourselves on delivering top-tier HVAC solutions for the residents of Montreal, Laval, Longueuil, and the surrounding areas. In this particular project, we completed the installation of a Senville Leto 18,000 BTU wall-mounted heat pump for a client in Montreal. This installation was a perfect example of how a high-efficiency, quiet, and eco-friendly system can enhance comfort while ensuring significant energy savings. Our team at AirGreen made sure the installation process was seamless and professional, showcasing our dedication to quality and customer satisfaction.
Enhancing Comfort with the Senville Leto: A Perfect Fit for Montreal Homes
As temperatures in Montreal fluctuate drastically throughout the year, having a reliable and efficient heating and cooling solution is essential. The Senville Leto 18,000 BTU Heat Pump provides both heating and cooling capabilities, making it an ideal choice for homeowners who want year-round comfort. This particular system is designed to operate efficiently even in extremely cold temperatures, down to -15°C, ensuring consistent warmth during Montreal's harsh winters.
Our client in Montreal was looking for a solution that not only offered energy savings but also quiet operation, and the Senville Leto perfectly matched their requirements. The heat pump boasts a 19 SEER (Seasonal Energy Efficiency Ratio), indicating its high efficiency, which translates into up to 48% energy savings compared to traditional systems. This made the Leto model a great choice for homeowners wanting to reduce their carbon footprint and save on energy bills.
The Installation Process: Precision and Efficiency
When it comes to HVAC installations, precision is key. The installation of the Senville Leto involved careful planning and attention to detail to ensure optimal performance and longevity. Our expert technicians at AirGreen assessed the client's property to determine the best location for the outdoor and indoor units.
- Outdoor Unit Placement: The outdoor condenser was mounted securely on brackets to minimize vibration and ensure stability. Positioned in an open area, the unit can operate efficiently with unrestricted airflow.
- Indoor Unit Placement: The indoor unit was installed in a central location within the home to ensure balanced temperature distribution across the living space. With its sleek and modern design, the indoor unit blends seamlessly with the home's interior, offering both functionality and aesthetic appeal.
One of the standout features of this installation was the use of the Senville installation kit, which includes pre-charged refrigerant piping. This made the installation process faster and more cost-effective, as there was no need for additional parts or equipment. Furthermore, our team ensured that the refrigerant lines were carefully insulated to maximize efficiency and prevent any potential leaks.
Quiet and Efficient: Why the Senville Leto Stands Out
Noise levels are a major concern for many homeowners, especially when installing a heat pump in urban areas like Montreal. The Senville Leto addresses this concern with its quiet operation. The indoor unit operates at a noise level as low as 30 dB, which is quieter than a typical conversation. Meanwhile, the outdoor unit produces only 57 dB, making it one of the quietest options on the market for its size.
This low noise level is achieved through DC inverter technology, which allows the heat pump to adjust its speed based on the current cooling or heating demand, thus eliminating the need for constant on-and-off cycling that typically generates noise. Our client in Montreal was particularly impressed by the whisper-quiet operation, which allows them to enjoy comfort without the disturbance of a loud system.
Smart Technology for Modern Living: Control with Alexa
In today's world, convenience is a top priority for many homeowners. The Senville Leto comes equipped with smart technology, allowing users to control their system remotely using Alexa. Our client can now easily adjust the temperature, switch between modes, and even set up routines, all through voice commands or via the Alexa app. This feature is especially useful for clients who are frequently away from home, as it enables them to manage their HVAC system from anywhere, ensuring optimal energy efficiency and comfort.
With the Alexa integration, our client can also control the temperature in specific rooms, which is particularly useful for larger homes. This advanced technology ensures that the Senville Leto is not just an HVAC system but a comprehensive smart home solution.
Energy Savings and Eco-Friendly Performance
In addition to its impressive technological features, the Senville Leto is designed with energy efficiency in mind. The DC inverter technology reduces energy consumption by up to 20%, making it an environmentally friendly option. With rising energy costs and growing concerns about environmental impact, this heat pump offers significant advantages in both cost savings and sustainability.
The 19 SEER rating indicates that the Senville Leto is highly efficient, especially compared to older, less efficient systems. For our client, this means lower utility bills and a reduced carbon footprint, aligning with their goal of minimizing their environmental impact.

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
Six simple habits that keep the unit going. Your list stays on this device.
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.
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.
