Sharp THU: the R-410A wall unit that came before the CHU.
Two sizes, 12,000 and 18,000 BTU/h, on R-410A. No ENERGY STAR certification, not on the LogisVert list, cold-weather limit not published in the Sharp documents we checked. Own one? We take care of it, in Montreal, Laval, Longueuil, the South Shore and the North Shore. Looking for one? We also show you the CHU: $2,268 or $2,712 in LogisVert and heating down to -30°C.

The THU runs on R-410A. Here’s what that changes, and what it doesn’t.
Your THU works as before. What changes is the context: R-410A is an HFC that Canada is phasing down in steps, and Sharp’s current series have moved to R-32.
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.

LogisVert: the THU is not on the list.
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.
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 THU.
No question matches. Call us at 514 316-2973.
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.
Not as of October 6, 2026: its AHRI numbers are not on Hydro-Québec’s list, and since November 26, 2025, only an ENERGY STAR certified system is eligible.
The Sharp documents checked for this page don’t state it for the THU, and it is not on the NEEP cold-climate list. We check it at the free visit.
The CHU is Sharp’s current series: R-32, ENERGY STAR certified, on the LogisVert list ($2,268 or $2,712) and heating down to -30°C, according to Sharp.
The Sharp manuals checked for this page cover the Airest and the ZU, ZHU and BU, not the THU. We give you your unit’s warranty terms with the quotation.
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.
The model number is on the rating plate: a THU has numbers like AE-X12THU / AY-XP12THU. Send us a photo if needed.
Canada is gradually cutting consumption of HFCs like R-410A: -85% by 2036 compared with the baseline. The federal documents we checked don’t talk about shutting down units already installed. We explain what it changes for yours at the visit.
Yes, we do the diagnosis and the repair. Parts are ordered from Sharp’s Canadian distributor, subject to availability; we tell you before any cost is committed.
