Sharp dual-zone: two rooms, one unit outside.
Three Sharp dual-zones: the CU (down to -30°C, coming soon to AirGreen), the BU (down to -27°C) and the TU (R-410A, down to -20°C according to Sharp). The CU and BU get $3,000 in LogisVert. With two 18,000 heads, Sharp’s table gives 13,000 BTU/h to each room. We install them in Montreal, Laval, Longueuil, the South Shore and the North Shore.

At -15°C, 1 kWh of electricity gives 2.3 of heat.
According to ENERGY STAR, for the CU and BU multi-zones. The TU dual-zone isn’t certified.
1 kWh of electricity at -15°C: how much heat?
Electric baseboards: 1 kWh of heat for 1 kWh of electricity · ENERGY STAR cold-climate bar: 1.75
Coefficient of performance (COP) at -15°C according to ENERGY STAR. An electric baseboard turns all its electricity into heat, no more: its COP is 1. For cold-climate certification, ENERGY STAR requires at least 1.75 at this temperature.

What people ask us about the Sharp dual-zone.
With the CU multi-zone, Sharp plans for every pair of CU heads of 9,000, 12,000 and 18,000 BTU/h. Rated system heating ranges from 20,200 to 26,000 BTU/h according to Sharp’s table.
$3,000 for the CU multi-zone (AHRI 217512785) and for the BU (AHRI 213927543), according to Hydro-Québec’s tool, checked on October 6, 2026. The TU dual-zone is not on the list.
It’s coming soon to AirGreen. The BU, the previous generation, is in the catalogue in dual- and triple-zone.
No. According to the Sharp CU/CHU manual, CHU units don’t connect to a multi-zone system. For several rooms on one outdoor unit, look at the CU multi-zone.
In the ZU, ZHU and BU manual, Sharp warrants the compressor for 7 years and other parts for 6 years, from installation. For the CU multi-zone and the TU dual-zone, we give you the exact terms with the quotation.
According to Sharp’s table, two 9,000 heads give the system 20,200 BTU/h of rated heat, the lowest of all pairs; 12,000 + 9,000 give 23,400; the other pairs, 26,000. We choose based on your two rooms.
According to Sharp, up to 25 m per head and 70 m in total for the CU multi-zone, with added refrigerant. We measure the real route at the free visit.
Yes, with the CU dual-zone, coming soon to AirGreen: the CU 18,000 head comes in dark grey (AY-XPC18CU-B) and connects to it, according to Sharp.
