The power of Quebec comfort signed CANAIR and installed by AirGreen

At AirGreen , we believe that comfort should never depend on the seasons. The CANAIR 4C28 Wall-Mounted Heat Pump is the perfect illustration of a system designed for the Quebec climate , where bitter winters and sweltering summers demand uncompromising performance. Designed and distributed by a Quebec family business since 1971 , this unit combines innovation, power and reliability to transform your home into a true haven of comfort, regardless of the outside temperature.

Elite energy efficiency – for comfort without waste

The CANAIR 4C28 uses Inverter technology , which automatically adjusts the compressor speed to your actual needs. The result: reduced energy consumption , quieter operation , and increased durability .

With an impressive SEER2 of 21.0 and an HSPF2 of 13.5 , this heat pump ranks among the best-performing systems in its class. Its low-impact R-454B refrigerant gas contributes to a reduced carbon footprint—a priority for AirGreen and our energy-conscious customers.

Thanks to its ENERGY STAR® Cold Climate certification, the 4C28 maintains its power even in the bitter cold of Quebec, providing reliable heating down to -30°C .

Smart, personalized comfort

Behind its sleek design lies a true concentration of technologies:

• Turbo Mode : Quickly reaches the desired temperature, perfect for freezing days or heat waves.

• Silent Mode : Almost inaudible operation for peaceful sleep.

• “Follow Me” function : the temperature adjusts depending on where the remote control is located — comfort follows you, literally.

• Self-cleaning interior and exterior : prevents mold growth and ensures system longevity.

• Cold draft prevention : no more cold feeling when starting in heating mode.

• Wi-Fi (optional) : Control your indoor climate remotely from your smartphone.

At AirGreen, our customers particularly appreciate the precision of this intelligent control. During a recent installation in Laval , a couple told us:

“Our old heat pump took minutes to respond. The CANAIR 4C28 adjusts everything instantly—it’s night and day!”
