The Révolution (UHD) is the ACD wall series whose sheet publishes −30 °C. Its 12,000, 18,000 and 24,000 sizes have NEEP records that list their maximum heat in deep cold: at −15 °C, 12,000, 20,000 and 24,000 BTU/h. Pick a size and a temperature: the calculator gives the listed heat and the number of days Montréal-Trudeau drops below that point.

01 · The heat listed on NEEP
NEEP lists the maximum heat of each Révolution at fixed test temperatures. Pick a size and a point: we compare it with the nominal heating of the same size and count the days Montréal-Trudeau drops below that point.

AHRI certificate 201863351 · ACD sheet
At 12,000 BTU, the Commodore23 heats a little more at 8.3 °C (13,000 against 12,200 BTU/h, AHRI certificate against NEEP record). In deep cold, only the Révolution 12,000 has listed values: 12,000 BTU/h at most at −15 °C. It is also the only one of the two that can be eligible for LogisVert: indicative amount of $1,236 (calculation under the four-size table). Only Hydro-Québec confirms the assistance granted.

The ACD sheet and the UHD manual (INS528) publish a heating range of −30 to 24 °C for the four Révolution sizes. On NEEP, only the Révolution 24,000 is listed at −30 °C: 9,600 BTU/h at most, with a COP of 1.80. The Révolution 12,000 and 18,000 are listed down to −20.6 °C: 12,000 and 20,200 BTU/h at most, as much as or slightly more than at −15 °C (12,000 and 20,000). These are the values as NEEP lists them. At Montréal-Trudeau, the daily low drops below −30 °C on 0.21 day a year on average.
ACD Révolution sheet; UHD manual (INS528), p. 6; NEEP list, records 406804 to 406806; ECCC, 1991-2020 normalsSince November 26, 2025, Hydro-Québec only accepts ENERGY STAR heat pumps. The Révolution 12,000 (record 2649621) and the Révolution 24,000 (record 2415080) are cold-climate ENERGY STAR: indicative amount of $1,236 and $2,400, calculated by AirGreen under Hydro-Québec’s rule ($120 per 1,000 BTU/h at −8 °C) on the nominal 17 °F (−8.3 °C) capacity of their ENERGY STAR records, 10,300 and 20,000 BTU/h; this is not the maximum listed on NEEP. Only Hydro-Québec confirms the assistance granted. The Révolution 9,000 has no ENERGY STAR record, and its outdoor unit is below the 12,000 BTU/h cooling minimum set by the guide.
ENERGY STAR 2649621 and 2415080; Hydro-Québec notice on the November 26, 2025 list update (ENERGY STAR only); LogisVert guide 1.10, p. 14The ENERGY STAR list read on November 5, 2026 does not hold the UHD18KCH25S-O / UHD18KCH25S-I pair sold in the shop. The pair sold is listed on NEEP (record 406805), not on ENERGY STAR: under the rule of November 26, 2025, the Révolution 18,000 therefore cannot be eligible for LogisVert.
ENERGY STAR list, November 5, 2026; NEEP list, record 406805The 38 comes from the ACD sheet, under the SEER standard. For the Révolution 12,000, 18,000 and 24,000, NEEP lists a SEER2 of 24, 22 and 21.5, and an HSPF2 (region IV) of 8.5, 10 and 9.5; the ACD sheet gives them a SEER of 30.5, 24.5 and 21.5. The two standards do not measure the same way: a SEER and a SEER2 do not compare, even when they land on the same figure, like the Révolution 24,000’s 21.5. The Révolution 9,000 sold in the shop has no published SEER2 value.
ACD Révolution sheet; NEEP list, records 406804 to 406806Per the ACD sheet, the indoor unit of the Révolution 9,000 goes down to 19 dB(A), the 12,000’s to 22 dB(A), and the 18,000’s and 24,000’s to 34 dB(A). Outdoors, the sheet gives 53 dB(A) for the Révolution 9,000 and 12,000, and 59 dB(A) for the 18,000 and 24,000. For reference, Québec.ca places a peaceful area at 40 dB(A) and the beginning of disturbance at 50 dB(A); the ACD sheet does not print the measurement conditions.
ACD Révolution sheet; Québec.ca, "Noise measurement" (June 16, 2022)The size is decided at the on-site assessment of the room’s heating needs. The NEEP list helps to see the margin in deep cold: at −15 °C, the Révolution 18,000 is listed at 20,000 BTU/h at most, more than its 18,000 BTU/h of nominal heating, and the Révolution 24,000 at 24,000 BTU/h.
