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.
A Symphony of Efficiency and Elegance: Another Success Story in Ville-Marie!
Meeting Specific Needs with Precision
In the vibrant heart of Ville-Marie, we at AirGreen recently accomplished another installation masterpiece that left our customer overjoyed and his neighbors envious. The client approached us with specific requirements: a compact, quiet, efficient machine with robust warranty coverage, capable of providing warmth during the chilly months, all while being eligible for provincial grants. Enter the Tosot Lomo 23, a Wall-Mounted Heat Pump designed to meet and exceed expectations.
The Tosot Lomo 23: Small but Mighty

- Heating Efficiency: Operative at -25°C, ensuring a cozy atmosphere even in the depths of winter.
- Silent Operation: With an interior sound pressure level ranging between 29 to 43 dB(A), it whispers rather than roars.
- Energy Efficiency: Boasting a 23.0 SEER rating and Energy Star® certification, the Lomo 23 is a paragon of efficiency.

Installation: A Tale of Precision and Care
Our team, armed with expertise and a commitment to excellence, embarked on installing this petite powerhouse in the client’s living room adjacent to the balcony. The location demanded a unit that would blend seamlessly into the living space without disrupting the tranquility of the home with noise or bulk. The Tosot Lomo 23 was the ideal candidate, with its sleek dimensions (Interior: 33.4 x 8.2 x 11.4; Exterior: 33.4 x 12.6 x 21.3) and optional WiFi connectivity for smart, hassle-free operation.
Grants and Savings: Maximizing Value
The Lomo 23 doesn’t just bring comfort; it brings savings. With eligibility for a substantial Federal Grant ($2,500 to $5,000) and a Provincial Grant ($340), it’s an investment that pays back. Our client was not only thrilled with the immediate benefits but also with the long-term value packed into this installation.

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.
