Zephyr UB32 wall-mounted heat pump: up to 32 SEER2 and -30 °C.
The R-454B UB32 is the most efficient Zephyr wall unit: 32 SEER2 at 9,000 BTU/h, ENERGY STAR cold-climate certified, heating down to -30 °C. Its three sizes, 9,000, 12,000 and 15,000, share the same cabinets and give 13,000 BTU/h at -8.3 °C per Zephyr. At 12,000 and 15,000: $1,560 of LogisVert.
Heat at -15 °C for each size, per Zephyr.

1 kWh of electricity, how much heat?
The first panel gives the COP of each UB32 at +8.3 and -15 °C; the second, the electricity needed to cool a season based on each size’s SEER2.
COP per the Zephyr BRO_2606 brochure; resistance heat: 100% (US DOE), so COP 1.
Illustrative math: SEER2 is, by definition (DOE, Appendix M1), the heat removed over the season divided by the electricity used, in BTU per watt-hour. Cost at Hydro-Québec’s Rate D second-tier price (11.142¢/kWh since April 1, 2026), which applies if use exceeds the first tier (40 kWh per day, times the number of days in the period); below it, a kWh costs 7.065¢. Before taxes and access fees. Your home will have its own numbers.
At +8.3 °C, the UB32 9,000 and 12,000 deliver 4.6 kWh of heat per kWh of electricity, the highest COP of any Zephyr wall unit.Source: BRO_2606 brochures, “heating COP at 8.3 °C”.

The UB32’s R-454B.
The UB32 uses R-454B, an A2L refrigerant with a GWP of 470, a blend of R-32 and R-1234yf. In Canada, no GWP limit applies to residential heat pumps (SOR/2016-137, Schedule 1.1).
GWP and ASHRAE class per the EPA (SNAP, March 19, 2026). A2L: mildly flammable, burning at most 10 cm/s.
Factory charge per the BRO_2606 brochure, in ounces. Scale: 0 to 72 oz.
Every UB32 holds 52.91 oz of R-454B from the factory, whatever its size.Source: UB32 brochure BRO_2606.

10 years on parts, a 6-year legal warranty.
Zephyr’s base warranty covers the UB32’s parts for 10 years. For a heat pump bought new on or after October 5, 2026, the law adds a 6-year warranty of good working order, counted from delivery.
on parts, per the UB32 BRO_2606 brochure and TTI page. “A labour warranty is available”: ask your contractor.
For a heat pump or air conditioner bought new from a merchant on or after October 5, 2026, Quebec law adds a free, automatic 6-year warranty of good working order, counted from delivery (Office de la protection du consommateur). Under TTI’s parts policy (v3.4, July 17, 2026), labour to replace a part during that period falls on the installing contractor.
Service or repair by anyone not certified and authorized by TTI (or Kinghome) ends the manufacturer’s conventional warranty (TTI, s. 4.4).
If something breaks, you call the contractor who installed it; they file the claim with TTI.
TTI’s policy asks owners to clean the indoor unit filters at least once a month (s. 6.3).
