CANAIR 4C22 Wall-Mounted Heat Pump | 12,000 BTU - R454B - 220V | Montreal

Performance reinvented for your everyday comfort

At AirGreen, we know Quebec’s climate well. Between icy January winters and humid July summers, your home deserves a heating and cooling system that can handle it all. That is what the CANAIR 4C22 wall-mounted heat pump offers, combining inverter technology, energy efficiency, reliability and comfort.

The CANAIR 4C22 series is distributed in Quebec by Descair, a Quebec family business founded in 1971, which means local supply and local support, whether you live in a condo in Montreal, a single-family home in Laval or a property on the South Shore.

CANAIR innovation: a heat pump for your well-being

Next-generation inverter technology

The heart of the CANAIR 4C22 is its inverter technology, which continuously adjusts the compressor output to your home’s actual needs. Unlike traditional systems that constantly switch on and off, inverter technology keeps operation steady, which means:

• A constant, comfortable indoor temperature, without unpleasant swings;

• Lower energy use, and therefore lower electricity costs;

• Quieter operation that extends compressor life;

• A fast response in both cooling and heating.

The result: a system that adapts to your lifestyle while minimizing wear and maximizing performance.

A unit for Quebec’s climate

Reliable heating down to -15°C

The CANAIR 4C22 heats down to -15°C. According to NEEP, it delivers 9,300 BTU/h at -8°C (COP 2.39) and 8,000 BTU/h at -15°C (COP 1.91). Like any heat pump, its capacity drops as the outdoor temperature falls: we take this into account when we assess your needs.

An environmentally responsible choice

Running on electricity, the CANAIR 4C22 emits far less greenhouse gas than a natural gas or oil system.
Its R-454B refrigerant has a global warming potential of 466, compared with 2,088 for R-410A.

A smart investment for your home

Whether you are replacing an old unit or equipping a new build, the CANAIR 4C22 offers excellent value for money. Its low consumption and durability make it a cost-effective long-term solution that improves your quality of life.

Complete comfort: quiet, design and adaptability

Very discreet operation

Comfort also means quiet. With an indoor sound level between 21 and 44 dB(A), the CANAIR 4C22 is easy to forget.
Whether in a bedroom, living room or office, it keeps the atmosphere peaceful. Silent mode lets you sleep undisturbed.

Compact, clean design

Thanks to its compact dimensions (31.57 x 7.44 x 11.69 in for the indoor unit), the CANAIR 4C22 fits elegantly into any interior. Its minimalist white front and clean lines blend into your decor.

This flexibility makes it ideal for small urban spaces in Montreal as well as houses on the North Shore.

Smart features that make everyday life easier

• Turbo mode: quickly reaches the desired temperature after a hot or freezing day.

• Self-cleaning function: limits mould and extends coil life.

• “Follow Me” function: the remote measures the room temperature and adjusts the climate around you.

• Cold-draft prevention: gentle start in heating mode.

• Automatic restart: resumes previous settings after a power outage.

• Wi-Fi (optional): remote control through a mobile app, so you can adjust the temperature before you get home.
