Hydro-Québec LogisVert list of October 27, 2026 (owner, existing home), same amounts as on October 8. LogisVert requires an outdoor unit of at least 12,000 BTU/h nominal and an ENERGY STAR heat pump (guide version 1.10). Hydro-Québec confirms the amount when you apply.

05 · 115 V

Four units run on 115 V. All the others, on 230 V.

The C22 and the 4C22 come in 115 V, in 9,000 and 12,000 BTU/h. The choice mostly depends on room in your electrical panel: we check it at the visit (AirGreen holds subclass 16, electrical, of its RBQ licence).

07 · Questions

What people ask us before picking a wall unit.

Which series heats all winter?
The 4C28 (every size) or the C28 from 9,000 to 24,000 BTU/h: they heat down to -30 °C, per CanAir. The C22, the 4C22 and the C28 30,000 and 36,000 stop at -15 °C.
What is the difference between the C28 and the 4C28?
The refrigerant: R-410A for the C28, R-454B for the 4C28. Both heat down to -30 °C (the C28 only from 9,000 to 24,000). The 4C28 goes up to 33,000 BTU/h; the C28, up to 36,000.
And between the C22 and the 4C22?
Both heat down to -15 °C and come in 115 V. The C22 runs on R-410A and goes up to 24,000 BTU/h; the 4C22 runs on R-454B and goes up to 18,000.
Which CanAir wall unit is the most efficient?
For cooling, the C28 9,000: SEER2 28.1 and EER2 16.2. For heating, the 4C28 24,000: HSPF2 13.5 (region IV). Figures from the CanAir brochures.
Which wall units qualify for LogisVert?
Seven, per Hydro-Québec’s list of October 27, 2026: C28 12,000, 18,000 and 24,000 ($1,200 to $2,544), and 4C28 12,000, 18,000, 24,000 and 33,000 ($1,440 to $3,840). Three 4C22 units join them with the “-P” indoor unit.

No. The four 115 V units (C22 and 4C22, in 9,000 and 12,000) heat down to -15 °C. For -30 °C you need a C28 or a 4C28, on 230 V.
