Down to -15°C, the ZHU 18,000 and the CHU 18,000 move together.
Lower down, the ZHU stops at -27°C according to Sharp; the CHU 18,000 still delivers 11,800 BTU/h at -30°C.
Maximum heat: Sharp spec sheets (-20°C to -30°C) and ENERGY STAR (-8°C and -15°C). Montreal temperatures: MétéoMédia (2021 and 2025) and 1871-2024 records.
Your ZHU already runs on R-32.
Your ZHU already uses R-32, like the ZHU1 and the CHU. The ZHU 18,000 is even ENERGY STAR certified and on the LogisVert list; the ZHU 12,000 isn’t.
Global warming potential (100 years)
100-year global warming potential: about three times lower for R-32.
What’s in R-410A
R-410A is a blend, half R-32 and half R-125. Current Sharps use R-32 alone.

We looked up every AHRI number on our product pages in Hydro-Québec’s tool on October 6, 2026. Every Sharp on the list is rated cold climate: $120 per 1,000 BTU/h of heat at -8°C.
| Sharp system | AHRI | Heat at -8°C | LogisVert |
|---|---|---|---|
| ZHU 18,000AE-X18ZHU + AY-XP18ZHU, previous generation | 209424784 | 22,600 BTU/h | $2,712 |
Since November 26, 2025, only an ENERGY STAR certified system is eligible.
The outdoor unit must have a rated capacity of at least 12,000 BTU/h.
The grant never exceeds 100% of the pre-tax cost.
Deadline to apply: 9 months after installation (LogisVert guide, version 1.10).
22,600 BTU/h at -8°C × $120 per 1,000 BTU/h = $2,712

What people ask us about the ZHU.
Yes, it remains in the catalogue in 12,000 and 18,000 BTU/h. Sharp’s current series are the CHU, CU, FilterSweep and Airest; the ZU1 and ZHU1 are still offered.
The ZHU 18,000 does: $2,712 according to Hydro-Québec’s tool, checked on October 6, 2026 (AHRI 209424784). The ZHU 12,000 doesn’t: it is not on the list.
Down to -27°C, according to Sharp. At -15°C, the ZHU 18,000 delivers 19,500 BTU/h according to ENERGY STAR.
At 18,000, the ZHU and the CHU both deliver 22,600 BTU/h at -8°C (ENERGY STAR). The CHU heats down to -30°C according to Sharp, against -27°C for the ZHU.
In its manual, Sharp warrants the compressor for 7 years and other parts for 6 years, from installation. Keep your proof of purchase and installation date: Sharp asks for them.
The current CHU, CU, FilterSweep and Airest series have a built-in Wi-Fi adapter, according to Sharp. For previous generations, we check it at the free visit.
At -8°C and -15°C, yes: 22,600 and 19,500 BTU/h according to ENERGY STAR, and $2,712 in LogisVert for both. The difference: the CHU heats down to -30°C according to Sharp, the ZHU down to -27°C.
