Designed for Quebec's harsh winters and humid summers, this ductless heat pump stands out for its exceptional energy efficiency, installation versatility and long-term durability .

The 4C28 series embodies the new generation of Cold Climate systems adapted to our northern conditions, offering reliable heating down to -30°C without compromising performance or indoor comfort.

Advanced technology designed for efficiency

The controlled power of the Inverter system

The technological heart of the CANAIR 4C28 is based on Inverter technology , an intelligent system that automatically adjusts the compressor frequency according to the actual needs of the home.
This allows:

• Significantly reduce energy consumption and therefore monthly costs.

• Maintain a stable and uniform temperature , without sudden variations.

• Provide fast and precise heating and cooling .

• Ensure quiet operation , ideal for bedrooms and living spaces.

A system designed for extreme conditions

The 4C28MC648H21 works with R-454B refrigerant , a new generation ecological gas, classified A2L, more environmentally friendly than the old R-410A refrigerants.
ENERGY STAR® (Cold Climate) certified, it boasts impressive energy performance:

• SEER2: 23.0

• HSPF2: 11.0

• EER2: 12.0

Even in the most intense cold, the heat pump maintains optimal heating capacity , thanks to its heating cables integrated around the compressor and its anti-frost technology , guaranteeing a smooth start every time.

Unparalleled installation flexibility

Up to 4 independent comfort zones

With its Quad Zone configuration (4 zones) , the CANAIR 4C28 offers the possibility of connecting several indoor units depending on the configuration of the home.
This means that each space—living room, bedrooms, basement, or office—can be independently air-conditioned or heated, for tailored comfort.

Compatible indoor units include models:

• 4C28SEH06H21 (6,000 BTU)

• 4C28SEH09H21 (9,000 BTU)

• 4C28SEH12H21 (12,000 BTU)

• 4C28SEH18H21 (18,000 BTU)

• 4C28SEH24H21 (24,000 BTU)

• 4C28SEH33H21 (33,000 BTU)

This modularity allows our certified installers to adapt each project to the surface area and layout of the rooms , whether for a bungalow, a townhouse, a duplex or a condo .

A design thought for tranquility

Quiet, reliable and durable

The CANAIR 4C28 combines manufacturing quality and Quebec engineering , offering an exterior noise level of only 65 dB(A) .
Thanks to the “Silent Mode” function , the indoor units reduce noise to a minimum, creating a soothing environment, day and night.

TU1 copper coils provide excellent corrosion resistance, while the self-cleaning function prevents mold growth and improves indoor air quality.

An unmatched guarantee for your peace of mind

CANAIR and AirGreen offer a full warranty of up to 10 years on parts and compressor , as well as an optional 10-year extended warranty on labor , demonstrating the exceptional reliability of the system.

These guarantees reflect a concrete commitment to sustainability and customer satisfaction.

Fewer emissions, more savings

By replacing an old natural gas or oil system with a CANAIR 4C28 heat pump , you help reduce your greenhouse gas emissions while lowering your annual energy costs .
The electricity used by these systems is clean and renewable , which fits perfectly with Quebec's environmental vision.
