NEEP certifies the airHome 800 down to -22°F (-30°C), the coldest point of Hitachi’s three wall series. Hitachi claims 100% heating capacity down to -20°C. Montréal-Trudeau’s 1981-2010 normals count 0.27 nights a year below -30°C. Here is what each size gives, from 8.3°C down to -30°C.
R-32Maximum output and COP certified by NEEP at the coldest point (-22°F). Right: indicative LogisVert; list read Oct. 14, 2026, amounts recomputed Oct. 28, 2026 from the certificates.
Each product page gives the AHRI number, the certified figures and the LogisVert amount of the size.
Each stop gives every size’s maximum output, on one scale, and the COP where NEEP certifies it. The bars shorten as the cold deepens. Even at -30°C, every size still heats.
BTU/h, maximum output
The certificates’ reference point. Every size gives more than its rated output here.
BTU/h, maximum output
The point Hydro-Québec reads for LogisVert. The certified rated heat there is lower than the maximum: 8,000, 11,000, 16,000 and 16,000 BTU/h.
BTU/h, maximum output
Every size still gives more than its rated heating output as published by Hitachi.
BTU/h, maximum output
The “100%” threshold: the maximum equals the brochure’s rated heating output (25,500 for the 24,000, against 25,400).
BTU/h, maximum output
Every size keeps more than 70% of its rated heating output as published by Hitachi.
BTU/h, maximum output
At full output, the 9,000 has a COP of 0.97: a little less heat per kWh than resistance heating, whose COP is 1. The 24,000 keeps 1.57.
Hitachi publishes -30°C (-22°F) on its English Canadian page, in its brochure and in the 18,000 and 24,000 operation manual; NEEP certifies that point. One section of the technical catalogue gives -25°C.
Nights: 1981-2010 climate normals, Montréal-Trudeau (ECCC); -30°C is the coldest threshold in those normals.
Nights per month with a low below -30°C
1981-2010 climate normals, Montréal-Trudeau, ECCC. April to November: 0.
Efficiency: Hitachi’s brochure and NEEP agree, except on the 9,000’s Region V HSPF2, shown with both values. Hitachi states its ratings follow AHRI 210-240.
SEER2 of 26.5 and EER2 of 16.1: the highest of our 15 Hitachi wall units. Under LogisVert’s 12,000 BTU/h nominal minimum.

Both are certified at 16,000 BTU/h at -8.3°C: Hydro-Québec grants the same amount for either. Elsewhere, the 24,000 leads in deep cold, the 18,000 in efficiency.

Pick a size, a mode and a speed. Per the brochures, the airHome 800 is the only one of the three series whose indoor sound changes between cooling and heating, on the 9,000 and 12,000.
Indoor sound pressure published by Hitachi, SL (silent mode) to HH; in heating, the 9,000 and 12,000 have their own values. Outdoor unit at high speed, cooling · heating: 52 · 52 (9,000 and 12,000), 52 · 54 (18,000), 55 · 55 dB(A) (24,000). Catalogue conditions: anechoic chamber, 1 m from the discharge grille and 0.8 m below the unit’s centre, 5 m of line with no lift.
The two small sizes take 30 m of line and 20 m of height difference, the two large ones 50 m and 30 m. All keep their factory charge up to 15 m.

Per the installation manuals of both size pairs.
For the 18,000 and 24,000. As we read its snow-hood section, the manual also calls for 800 mm between the drain hole and the ground.
Qualified technician, specified lines and cables, earthing, no refrigerant purging, dedicated breaker: the points the manuals insist on.
What Hitachi supplies and documents for the airHome 800, and the upkeep its manuals ask of the owner.
It installs inside the unit. The airCloud Go app adds Smart-Fence, the weekly timer, the energy cost estimator and voice control.
The technical catalogue gives it a section; the Canadian page confirms compatibility with a wired wall controller.
Adapter in the technical catalogue, which gives it sections on safety, installation, wiring, test run and the dry contact.
The series’ North American wireless remote, per Hitachi’s portal.
Hitachi provides for it on the airHome 400 and 600; the airHome 800 documents do not mention it, and we do not promise it.
Vacuum, then rinse in water under 40°C if needed, no detergent on the pre-filter, dry in the shade, unit switched off.
All four sizes are “cold climate” in the ENERGY STAR list (US market). The 9,000, certified at 9,500 BTU/h cooling, stays under the 12,000 BTU/h nominal minimum.
Math: heat certified at -8°C, in thousands of BTU/h, × $120. Hydro-Québec: list read Oct. 14, 2026, amounts recomputed Oct. 28, 2026 from the certificates. Full LogisVert rules (eligibility, deadlines, documents): our LogisVert page.

Yes, per the English Canadian page, the brochure and the 18,000 and 24,000 manual, and NEEP certifies that point (-22°F). At -30°C, maximum output runs from 5,500 BTU/h to 15,000 BTU/h depending on the size, with a COP of 0.97 to 1.57.
Hitachi writes “No need for auxiliary heating, no fossil fuel.” The certified figures also show output dropping with the cold: at -30°C, it falls to 5,500 BTU/h for the 9,000. Backup heating is decided during the visit, based on the house’s heating needs.
Per Hitachi’s brochure, the maximum output at -20°C equals the rated heating output: 12,000, 13,500 and 21,600 for the 9,000, 12,000 and 18,000, and 25,500 against 25,400 for the 24,000.
Because the grant follows the heat certified at -8°C, and both are certified at 16,000 BTU/h: 16 × $120 = $1,920.
The sources differ: 22,000 BTU/h of rated cooling per Hitachi’s brochure and catalogue, 24,000 BTU/h per NEEP, ENERGY STAR and Hydro-Québec. For anything tied to the certificate or LogisVert, 24,000 is the figure that counts.
Yes. The SPX-WFG03 airCloud Go adapter is supplied and installs inside the unit, out of sight.
Hitachi calls the family “XJ SERIES” (RAK-XJ…PHAA indoors, RAC-XJ…WHAA outdoors) without publishing a key for the letters.
