Is the Airy really the most efficient?

On SEER2, yes, at every size: none of our other Kinghome wall units does better at 9,000, 12,000, 18,000 and 24,000 (product pages read live). On HSPF2 Region IV, its 11.2 is the highest of our Kinghome wall units. On HSPF2 Region V (NEEP), it leads alone at 9,000 and 24,000 (8.5) and ties at 12,000 and 18,000 (8).

What is the “100% at -15 °C” promise worth?

Per NEEP, all four Airy units give at least their nominal size at -15 °C: 11,500, 12,200, 18,000 and 24,000 BTU/h. Against the rated heat at 8.3 °C, the 18,000 keeps 97% (details).

How much electricity to heat with an Airy?

Over a typical Canadian season (NEEP HSPF2 Region V), 1,000 kWh of heat takes about 401 kWh with an Airy 9,000 or 24,000 and 427 kWh with a 12,000 or 18,000, against 1,000 kWh for baseboards. It is indicative: the house, the settings and the weather change the figure (calculation).

What is the G-Storm compressor?

Kinghome’s name for the Airy’s compressor: it runs at up to 200 Hz, per the brochure. The brochure table describes it as a variable-speed rotary compressor. Kinghome publishes no further detail.

How far does the Airy blow?

Up to 50 ft (15.2 m), per the brochure. Its submittals give the airflow at each speed: 265 to 506 CFM for the 9,000 and 353 to 765 for the 24,000.

Indoors, 19 dB(A) at Sleep speed (12,000 BTU/h), per the product page and the submittal. The brochure claims 19 dB(A) for the 9,000 and 12,000; we follow the sheets. Outdoors, 55 dB(A) at its quietest. Test conditions not published.

At 12,000, the Airy has the better SEER2 (29.5 against 25.5) and the same HSPF2 Region V (8 on NEEP). The Polaris gives more rated heat at -8.3 °C (15,000 against 13,000 BTU/h), so a higher LogisVert ($1,800 against $1,560). For the summer bill, the Airy; for the grant and the rated heat, the Polaris.

What LogisVert amount for an Airy?

From $1,560 (12,000 BTU/h) to $2,760 (24,000 BTU/h): $120 per 1,000 BTU/h of heat at -8 °C. The 9,000 BTU/h units are not eligible. The calculation for each model is above; Hydro-Québec confirms the amount when you apply.

Which line set for an Airy?

Per the 2026 brochure: 10 to 100 ft and 60 ft height difference at 9,000 and 12,000; 10 to 131 ft and 82 ft at 18,000 and 24,000. Pre-charged for 7.5 m (24.6 ft); beyond that, 0.2 oz/ft (9,000, 12,000) or 0.4 oz/ft (18,000, 24,000) of R-32.

Which controls come with an Airy?

A YBE1FBF infrared remote, and Wi-Fi (“WI-FI control”) among the included features. Optional: four wired controls (XE71-44G, XE74-44E, XE72-44E, XE71-00/E), per the submittals.

Airy R32: the best SEER2 of our Kinghome wall units, at every size

At 9,000, 12,000, 18,000 and 24,000 BTU/h, none of our other Kinghome wall units does better on SEER2. Its HSPF2 Region IV of 11.2 (9,000 BTU/h), the product-page figure, is the highest of our Kinghome wall units, and per NEEP, all four Airy units keep at least their full nominal size at -15 °C. How much electricity to heat? The calculation is right below.

02 · Electricity

How much electricity for 1,000 kWh of heat?

HSPF2 says how much heat a heat pump gives per kilowatt-hour over a typical season. We use the Region V value, the Canadian climate one, and compare it with electric baseboards, which give 1 kWh of heat per kWh paid.

03 · The -15 °C promise

“100% of its capacity at -15 °C”: we checked.

The Airy brochure says the G-Storm compressor “delivers 100% heating capacity at -15°C”. We took the certified figures on NEEP for each size and did the math two ways.

Model	Rated at 8.3 °C	Max. at -15 °C	COP at -15 °C	of size	of rated at 8.3 °C	100%?
Airy 9,000	10,600	11,500	2.11	128%	108%	yes
Airy 12,000	12,200	12,200	2	102%	100%	yes
Airy 18,000	18,600	18,000	1.8	100%	97%	97%
Airy 24,000	24,000	24,000	1.8	100%	100%	yes

NEEP, Airy records (rated and maximum heat, BTU/h; COP), re-read Oct. 26, 2026. “Of size”: ratio to the nominal size (9,000, 12,000…). “Of rated”: ratio to the rated heat at 8.3 °C (47 °F).

VerdictTrue for all four sizes against their nominal size. Against the rated heat at 8.3 °C, the 18,000 keeps 97%: 18,000 against 18,600 BTU/h. At 18,000 and 24,000, that is the strongest retention of our Kinghome wall units at -15 °C; at 9,000 and 12,000, the Polaris does better.
