The quiet power of comfort: a heat pump designed for the Quebec climate

At AirGreen , we believe that indoor comfort should be smart, energy-efficient, and perfectly adapted to Quebec's climate. This is exactly what the CANAIR 4C22 | 9,000 BTU – R454B – 115 V Wall-Mounted Heat Pump offers, a reliable, quiet, and flexible wall-mounted solution designed to deliver exceptional performance, even when the mercury dips to −15°C.

Behind its sleek design lies engineering designed for performance: Inverter technology, low-impact R-454B refrigerant, and best-in-class energy efficiency.

A design 100% adapted to Quebec

CANAIR systems are developed by Descair , a Quebec family business founded in 1971. Their mission: to create air conditioning and heating solutions that truly withstand Canadian winters and increasingly hot summers.

The 4C22 series reflects this philosophy: a compact, aesthetically pleasing unit that's easy to install in homes, condos, or rental properties, while offering remarkably quiet operation . With an indoor noise level as low as 18 dB(A) , this heat pump is as discreet as it is efficient—ideal for bedrooms, home offices, or any space where quiet matters.

Inverter technology for comfort

Inverter technology adjusts the compressor frequency in real time according to energy demand. Result:

• Rapid heating and cooling , without sudden temperature variations;

• Reduced energy consumption , which translates directly into savings on the electricity bill;

• Constant comfort , whether in the middle of January or in the middle of a July heatwave.

With an efficiency rating of up to 21.5 SEER2 and 7.0 HSPF2 , the CANAIR 4C22 9,000 BTU rivals the best systems in its class.

Built to last: long-term quality and reliability

Each CANAIR 4C22 unit is assembled with high quality components:

• TU1 copper coil , recognized for its resistance to corrosion;

• Automatic restart after power outage;

• Self-cleaning function , which prevents mold growth in the indoor unit;

• Cold air draft prevention , for smooth start-up in heating mode.

These technical details not only guarantee long-lasting performance, but also complete peace of mind – especially since CANAIR offers up to 10 years of warranty on the compressor and parts .

Smart and practical functions for everyday use

The CANAIR 4C22 makes life easier for owners:

• Turbo mode allows you to quickly reach the desired temperature;

• The “Follow Me” function automatically adjusts the temperature around the remote control, ensuring precise comfort;

• Optional Wi-Fi provides the ability to control the device remotely via smartphone;

• Quiet mode creates a soothing atmosphere, perfect for family evenings or sleep.

An ecological and economical choice

Choosing a CANAIR heat pump means choosing an electric and clean solution. Thanks to the R-454B refrigerant gas, this unit produces significantly fewer greenhouse gas emissions than traditional natural gas HVAC systems.

In addition to being environmentally friendly, switching to a CANAIR system can be highly cost-effective . Whether for new construction, renovation, or replacing an existing system, the cost difference is often minimal compared to the long-term energy savings.

And to top it all off, Hydro-Québec is offering a $325 grant with the purchase of this model—a great incentive to go green!
