What does “100% heat down to -15°C” mean?

According to Hitachi (HeatForce technology), the wall unit keeps its full heating power down to that temperature. Colder than that, it still heats, with less power, down to its limit: -25°C for the airHome 600, -30°C for the airHome 800.

airHome 400: optional airCloud Go adapter. airHome 600: adapter included. airHome 800: adapter included, built into the unit. According to Hitachi.

A self-cleaning cycle: the wall unit freezes the room’s humidity on its indoor coil, then thaws it; the water carries the dust and dirt away. One button on the remote. The filter is still cleaned by hand, and a yearly inspection is still recommended.

How is the LogisVert amount calculated?

Hydro-Québec multiplies the certified heat at -8°C, in thousands of BTU/h, by $120 for an ENERGY STAR cold climate unit, or by $50 for a standard ENERGY STAR unit. The grant never exceeds 100% of the cost before taxes, and the AHRI number of the installed combination decides.

Who is the 115 V version for?

The 12,000 BTU/h airHome 400 also comes in 115 V (RAK-EJ12PHAA + RAC-EJ12WHAA, AHRI 216759659), with the same figures on its product page and the same LogisVert amount, $1,008. We check your electrical panel during the visit.

What warranties do I get?

Two warranties add up. Hitachi: 10 years on the compressor and on parts when the unit is registered within 60 days (otherwise 7 and 5 years); we do the registration for you. AirGreen: since October 5, 2026, your new heat pump is covered for 6 years, parts, labour and travel included (warranty of good working order under the Consumer Protection Act), with one professional maintenance a year as the condition.

How long do I have to claim LogisVert?

Nine months after installation. The calculator in the LogisVert section gives the exact deadline from your installation date.

Why is no price shown?

The price depends on the installation: line set length, support, electrical work, access. After a free visit, we give you a clear quotation with the model, the AHRI number and the indicative LogisVert amount.

Who installs it, and where?

AirGreen, holder of RBQ licence 5645-9605-01 (subclasses 15.8, 15.10 and 16), in Montreal, Laval, Longueuil, the South Shore and the North Shore. The in-home estimate is free.

Q: Does a 9,000 BTU/h wall unit qualify for LogisVert?

No. LogisVert requires an outdoor unit of at least 12,000 BTU/h nominal.

A Hitachi wall unit comes down to two numbers. The series (400, 600 or 800) tells you how cold it can go, from -20.5°C to -30°C. The size (9,000 to 36,000 BTU/h) follows the room. The grid below crosses both, with the certified heat and the LogisVert amount of each model.

05 · FrostWash and air quality

All three wash themselves, not all to the same degree.

A wall unit’s coil collects dust and mould, and the airflow drops. FrostWash freezes it, then thaws it: the ice carries the dirt away. Here is what each series adds, according to Hitachi.

Coil

Clean

Heats to 56°CThe coil melts greasy particles.
Freezes down to -15°CDirt and pollutants get trapped in the ice.
MeltThe ice melts, the water carries the dirt away: the coil comes out clean.

FrostWash 3.0, according to Hitachi’s airHome 600 and 800 brochures.

99.0%of viruses

99.0%of bacteria

Removed from the coil after a single FrostWash cycle: tests by the Kitasato Research Center of Environmental Science (test no. 2020_0650, model RAS-X22K), cited in Hitachi’s brochures.

“Not specified”: neither Hitachi’s Canadian page nor its brochure mentions it for that series. airHome 400 FrostWash: indoor only, according to its brochure. Reverse outdoor fan: DuraSpin. PM2.5 filter: captures 99% of fine particles according to Hitachi’s tests (JEM1467 standard). Dehumidification: from the smallest to the largest size, according to the brochures.

FrostWash doesn’t replace maintenance. The filter is still cleaned by hand, and a wall unit should be inspected once a year.
