CanAir Heat Pumps in Montreal: the Right Series for Your Winter
CanAir is the brand of Quebec distributor Descair. Its C22 and 4C22 wall units heat down to -15 °C, the C28 and 4C28 down to -30 °C. And the “4” in front of the name? Those models use R-454B refrigerant. We pick the series, the size and the LogisVert amount with you, checked in Hydro-Québec’s search tool.

01 · The 4 wall-mounted series
C22, C28, 4C22, 4C28: two numbers and a “4” to understand.
The 22 or the 28 tells you how cold it can be outside while the unit still heats. The 4 in front of the name tells you the refrigerant. Pick a series, then a size: we show the LogisVert amount found at Hydro-Québec, or why there isn’t one.
Series 4C28
The R-454B generation of the C28. Heats down to -30°C, from 9,000 to 33,000 BTU/h; Wi-Fi control optional.

02 · The cold
At -20°C, which CanAir units still heat?
Move the slider. We compare the heating operating range CanAir publishes, not the capacity: the colder it gets, the more capacity drops. Sizing and backup heat are worked out at the visit.

Number of rooms
3 rooms: each room gets its own wall head, and a single 4C28MC outdoor unit runs them all.

Each compressor has its own AHRI number and a single LogisVert amount, whatever the number of heads. The size of each head is chosen at the visit, room by room.
04 · 4CDH central or add-on
Have ductwork? A 4CDH heats through it down to -30°C.
Two ways to do it. The central system replaces your electric furnace with the 4CDH indoor unit. The add-on keeps your furnace and adds a CanAir coil to it. Pick one, then the size in tons.
4CDH side-discharge outdoor unit and 4CDH indoor unit with electric elements, in R-454B.
The CanAir “electric furnace”
It’s the 4CDH indoor unit of the central system, with optional electric elements from 5 to 25 kW. Same AHRI number as the central: one LogisVert amount per system.
Wired Wi-Fi controller
Included with the 4CDH central system, per the CanAir brochure. For the add-on, we confirm the controls in the quote.
Your gas or oil furnace
With the add-on, we install the heat pump and the coil. We don’t touch the burner or the gas or oil supply.
