Sharp ZU: the R-32 generation before the ZU1, still in the catalogue.

Four sizes, from 12,000 to 24,000 BTU/h, R-32 refrigerant, heating down to -27°C according to Sharp and a 7-year Sharp compressor warranty. We install and service it in Montreal, Laval, Longueuil, the South Shore and the North Shore. Worth knowing before you choose: it isn’t ENERGY STAR certified, and since November 26, 2025, LogisVert only accepts certified systems.

05 · From R-410A to R-32

Your ZU already runs on R-32.

Your ZU already uses R-32, like the ZU1 and the CU. What separates it from them is ENERGY STAR certification, and therefore LogisVert.

Global warming potential (100 years)

R-410A2,088
R-32675

100-year global warming potential: about three times lower for R-32.

What’s in R-410A

R-32 alone: current Sharps

R-410A is a blend, half R-32 and half R-125. Current Sharps use R-32 alone.

CanadaCanada is cutting HFC consumption in steps: -10% in 2019, then 2024, 2029 and 2034, down to -85% by 2036.
