The Commodore23 (OCD) is the only ACD wall series offered from 9,000 to 36,000 BTU. Its sheet publishes a maximum line of 15 m on the 9,000 and 30 m on the 30,000 and 36,000, and a 10 m height difference for all six sizes. Enter your run: the checker says which sizes accept it, the margin left and, for information, the refrigerant to add.

Maximum lengths and height difference, charge and additional refrigerant: ACD Commodore23 technical sheet (FR and EN); for 9,000 to 24,000, the INS515 manual gives the same lengths (p. 35). Minimum length of 3 m: ACD Commodore23 manuals. The real run is measured on site, and the clearances around the outdoor unit are checked on site.

15 mof margin on the 25 m published
✓Within the published limits: 10 m of line and 3 m of height difference, against 25 m and 10 m at most on the Commodore23 18,000.
Beyond 7.5 m (25 ft), the ACD sheet calls for 0.2 oz/ft: 2.5 m more, that is 8.2 ft × 0.2 oz/ft ≈ 1.6 oz.

At 18,000 BTU, ACD’s sheets give the two outdoor units the same footprint; at 24,000, they do not.

At 24,000 BTU, the Commodore23 outdoor unit is larger (43.6 × 31.1 × 16.8 against 37.6 × 27.6 × 15.6 in) and weighs 39 lb more (142 against 103 lb); the published sound (59 dB(A)) and line limits (25 m, 10 m of height difference) are the same. Beyond 7.5 m, both sheets call for 0.5 oz/ft of additional refrigerant, against 0.2 oz/ft up to 18,000.

ACD publishes −25 °C for the Commodore23 from 9,000 to 24,000: English sheet, text of the French sheet and INS515 manual. For the Commodore23 30,000 and 36,000, their manual gives −20 °C, and we use that figure. The table of the French sheet shows −20 °C for all six sizes; it is the only document that says so for 9,000 to 24,000.
ACD Commodore23 FR and EN sheets; INS515 and Commodore23 30,000 and 36,000 manualsNo. None of the six Commodore23 units is on the ENERGY STAR list read on November 5, 2026, nor on the NEEP list, searched by AHRI number and by model. Without an ENERGY STAR record, they cannot be eligible for LogisVert under the Hydro-Québec rule in force since November 26, 2025. The Commodore23 18,000 and 24,000 were on the Hydro-Québec list of May 1, 2025, before that change.

ACD Commodore23 sheetThey are the only ACD wall units above 24,000 BTU. Per their AHRI certificates, they give 28,400 and 34,600 BTU/h of heating at 8.3 °C; their sheet gives them 30 m of line, and their manual a heating limit of −20 °C. Their outdoor unit is also the loudest in the series: 62 and 65 dB(A) per the sheet.
AHRI certificates 202110509 and 202110510; ACD sheet and manualThe Commodore23 is chosen at the on-site assessment of the room’s heating needs; the run then decides between two neighbouring sizes: at 22 m of line, for example, only the Commodore23 18,000 to 36,000 accept it per the sheet.
