GREE CHARMO R32: its other names, figure by figure
Five 12,000 BTU R-32 wall units carry the same AHRI-certified values for the season and for the cold: GREE CHARMO, GREE VITA, GREE LIVO, KINGHOME CHARMO and TOSOT CHARMO. Only one certified value changes, at 8.3 °C. This page shows what they share, what differs, and how to recognize each name by its model number.
One certified core, five names, and the fine print to know.NEEP “Charmo” series, four AHRI certificates, verified November 9, 2026.

What the electricity costs, in dollars, winter and summer
AirGreen estimate for the same 12,000 BTU/h zone in Montréal, at Hydro-Québec Rate D, taxes included. The GREE CHARMO R32 and the TOSOT CHARMO R32 have two different AHRI certificates, but the same HSPF2 and the same SEER2: calculated exactly the same way, they come to the same amount, to the dollar. The GREE VITA R32 shares the GREE CHARMO certificate, and the GREE LIVO and KINGHOME CHARMO have the same values: their estimate is identical. Electric baseboards serve as the reference point.
How this amount is calculated
- Heat to supply over the winter. A zone whose heat loss reaches 12,000 BTU/h ( kW) at −23.1 °C, Montréal’s design temperature: kW × 24 h × 4,167 degree-days ÷ (18 − (−23.1)) = kWh of heat for round-the-clock heating, all winter. Heating degree-days (18 °C base) and design temperature: Natural Resources Canada, HOT2000 climate data, Montréal Intl station. With fewer hours a day (“Heating” slider), the heat is reduced in the same proportion, for the heat pump and the baseboards alike: a simplification that ignores the recovery after a temperature setback.
- Electricity for heating. Heat pump: heat × 3.412 ÷ HSPF2 Region V, the AHRI certificate value published by NEEP. Region V is the coldest in the standard, and its calculation includes the electric backup expected when the heat pump is no longer enough. Electric baseboards: 1 kWh of electricity for 1 kWh of heat.
- Electricity for cooling. 12,000 BTU/h ÷ SEER2 × hours per day × 60 days ÷ 1,000: the method of Hydro-Québec’s air-conditioning calculator, with the SEER2 seasonal efficiency from the AHRI certificate. The number of hours is a scenario, adjustable above from 1 to 24 h. At 24 h, the calculation assumes rated capacity all day: that is a ceiling, since a variable-speed unit slows down once the room is at the right temperature.
- Price. Hydro-Québec Rate D in effect April 1, 2026: 7.065¢ per kWh up to 40 kWh a day, 11.142¢ beyond; the average price, 9.104¢, is the one Hydro-Québec’s calculators use. GST and QST included. Grid access charges, the same with or without a heat pump, are not counted.
AirGreen method v1.1, November 9, 2026. An estimate is for comparing units under the same conditions. The actual bill depends on the house, insulation, settings and use; this amount is not a promise.
Five units on the wall, one certified fingerprint
Tap a unit. Its eleven certified values appear in the panel below, and the bar under each name lights up: teal when the value matches the selected unit, yellow when it differs. The photos show that indoor units, outdoor units and remotes do not all look alike, even when the figures are identical.
Values: AHRI certificates published by NEEP (records 389379, 393211, 369973 and 389341, accessed November 9, 2026) and the ENERGY STAR directory. Photos: AirGreen product images. The TOSOT CHARMO has no image on AirGreen’s site yet; no image is drawn in its place.
Same certified values, not necessarily the same documents
The certificates agree almost everywhere. The brochures, however, do not always say the same thing as the certificate for their own name. Here are the six discrepancies found by reading each document.
The TOSOT CHARMO goes higher at 8.3 °C
Its certificate 215406527 gives 14,600 BTU/h maximum at 8.3 °C, with a COP of 3.32. The four other names are certified at 12,000 BTU/h, COP 3.52. Lower down, from −8.3 to −25 °C, the five certificates are identical.
The HSPF2 does not move as a result
Despite the gap at 8.3 °C, the five certificates show the same HSPF2 of 8.5 (Region IV) and 7.3 (Region V), and the same SEER2 of 19.0. Hence the same estimated cost above.
Two brochures print the figure of another combination
The GREE LIVO R32 and KINGHOME CHARMO R32 brochures give a heating range of 3,070 to 14,600 BTU/h. Their certificates (214779350 and 217956851) give 12,000 BTU/h maximum at 8.3 °C. The GREE CHARMO sheet X61064B prints 3,070 to 12,100. This page follows the certificates.
The VITA brochure describes the previous combination
GREE Canada’s VITA R32 brochure no. 032025 gives the outdoor unit GWH12ATCXB-D6DNA1A/O and the certificate 214640135. AirGreen offers the current version, outdoor unit D6DNA4B/O, certificate 215402236, the same as the GREE CHARMO.
ENERGY STAR: the directory and NEEP do not say the same thing
The ENERGY STAR directory lists certificates GREE 215402236 and LIVO 214779350 (United States and Canada) and KINGHOME 217956851 (Canada), all “cold climate”. The TOSOT CHARMO is not listed, and NEEP does not give it the cold-climate designation. NEEP’s ENERGY STAR field reads “no” for all five; this page follows the official directory.
Published sound depends on the document
The GREE CHARMO sheet gives 32 to 39 dB(A) over three speeds, the VITA brochure 22 to 47 dB(A) over eight levels, the LIVO and KINGHOME sheets 27 to 47 dB(A). Same certified values, but different ways of presenting the noise: see “Sound”.
Three GREE certificates for the same series, in three stages
Under the CHARMO name, NEEP keeps three GREE 12,000 BTU certificates. The first combination used R-410A. The second switched to R-32 with 14,600 BTU/h at 8.3 °C. The current version keeps R-32 and is certified at 12,000 BTU/h at 8.3 °C. The cold points did not change from one stage to the next.

R-32Below −15 °C: every published figure, at its exact temperature
NEEP certifies all five names at the same points: 9,100 BTU/h at −15 °C and 6,500 BTU/h at −25 °C, maximum. GREE also publishes, for the LIVO R32, a maximum-capacity table down to −26.1 °C. Each figure sits at its own temperature, with its source. Nothing is calculated between two points.

The documents consulted are those for the 12,000 BTU size of each name. A feature missing from a brochure is not necessarily missing from the unit: the brochure simply does not mention it.
Noise, as each document publishes it
AHRI certificates do not measure noise. Each document presents it in its own way: three named speeds, eight unnamed levels, or a simple range. The figures come from the same certificate or from identical certificates, but not from the same way of displaying them.
How to read these figures. dB(A) measures a noise level as the ear perceives it: the lower the figure, the quieter the unit. Each point is a published value, from lowest to highest.
Why this is not a ranking. None of these documents gives the distance or the measurement conditions. A wider range can come from one more speed in the document, not from a louder unit.

Highest published value
Measurements published by each document using its own method: read them separately, not as a ranking.
The GREE CHARMO sheet X61064B lists 62 dB(A) outdoors without saying whether it is sound pressure or sound power; the three other documents give 52 dB(A). No TOSOT CHARMO 12,000 BTU document was found.
Same published dimensions, different fronts
Indoor units to scale
Width × height × depth: VITA brochure 032025, LIVO brochure and KINGHOME sheet. The GREE CHARMO sheet X61064B gives no dimensions; those of units with the same base number (GWH12ATCXB) are used. Same published width; the photos show different fronts and louvers.
Is your wall wide enough?
All five names publish the same width, 32 7/8 in. Clearances around the unit are in the installation manual; the installer confirms them on site.

What people ask about these five names
GREE CHARMO, VITA, LIVO, KINGHOME CHARMO, TOSOT CHARMO: what is the difference?
Their AHRI-certified values are the same for SEER2, EER2, HSPF2 and the points from −8.3 to −25 °C. The TOSOT CHARMO is certified higher at 8.3 °C (14,600 versus 12,000 BTU/h maximum). The indoor unit, the outdoor unit, the remote, the app and the warranty may vary from one name to another.
Do the GREE CHARMO and the GREE VITA have the same certificate?
Yes, in the version AirGreen offers: AHRI certificate 215402236, outdoor unit GWH12ATCXB-D6DNA4B/O. VITA brochure no. 032025 still describes the previous combination, 214640135.
Why does the KINGHOME brochure say 14,600 BTU/h and this page 12,000?
The KINGHOME sheet gives a heating range of 3,070 to 14,600 BTU/h. AHRI certificate 217956851, published by NEEP, lists 12,000 BTU/h maximum at 8.3 °C. When sources disagree, this page follows the certificate.
Down to what temperature do they heat?
The documents state heating down to −25 °C. NEEP certifies 6,500 BTU/h maximum at that temperature, for all five names. A GREE table for the LIVO R32 goes down to −26.1 °C (8,030 BTU/h), outside AHRI test conditions; below that, no capacity is published.
Does the operating cost change from one name to another?
No, in our method: the calculation uses HSPF2 Region V and SEER2, identical on all five certificates, despite the TOSOT CHARMO’s gap at 8.3 °C.
Which ones are listed in the ENERGY STAR directory?
At the verification date, the directory lists certificates GREE 215402236 and LIVO 214779350 (United States and Canada) and KINGHOME 217956851 (Canada), with the cold-climate designation. TOSOT CHARMO 215406527 was not found there.
Are they eligible for rebates?
Eligibility depends on the official list in effect on the date of purchase. This page promises no amount; the current list is checked at the time of the quote.
