Kinghome wall heat pumps: what it takes to install one in your home
22 R32 wall units in four series, from 9,000 to 36,000 BTU/h. To pick a series by what matters to you, the Kinghome page has its selector and comparison table. Here, we answer the installation questions: space on the wall, the line to the outdoor unit, the electrical circuit and the heat left when it is -25 °C.
Who makes which size?
All 22 formats at a glance. Each pill opens the product page.

Everything to know
Everything to know before installing a Kinghome wall unit
Montreal cold, outdoor noise, wall space, room size and what the technician must follow. Everything comes from Kinghome Canada documents, NEEP, ENERGY STAR, Environment Canada and Québec.ca.
03 · Deep cold
At each published temperature, how much heat is left.
Pick a size and a temperature: the four series show the maximum heat published on NEEP, the COP and the minimum heat. Below their coldest published point, a series is marked out of range.

What the Kinghome documents require, in numbers.
The R32 Split Type outdoor unit manual covers Charmo, Clivia and Airy; Polaris has its own manual (Sept. 24, 2026), with the same installation rules. All four series have their submittals.
Above any surface
45 cmThe submittals of all four series want the outdoor unit at least 18 in (45 cm) above any surface, for snow and defrost water.
The manual’s minimum
3 / 20 cmAt least 3 cm under the unit for the drain joint, 20 cm for a model with a heating element. The support must carry 4 times the unit’s weight.
Pre-charge
7.5 mThe outdoor unit is pre-charged for 7.5 m (24.6 ft) of line. Beyond that, R-32 is added per the table.
Vacuum
-0.1 MPaVacuum pump 10 to 15 minutes, pressure must hold at -0.1 MPa, then 1 to 2 minutes with the pump closed. Then, “Leak test is a must after installation”.
Clearances
30 cmAt least 30 cm between the outdoor unit and the wall; 30, 50 and 200 cm to obstacles depending on the side (manual diagram).
Bending
10 cmMinimum bending radius of 10 cm. If the outdoor unit is higher than the wall hole, a U-shaped loop keeps rain out.
Base-pan heater
68-160 WPer NEEP, each of our Kinghome wall units listed on NEEP has one, on during defrost and below 1 °C (Polaris 24,000: below -5 °C).
Breaker (MOP)
15-30 AThe maximum breaker rating, from the product page; 20 A for the 115 V models. Details in the table below.
R-32 refrigerant

Per the 2026 brochures, the line is at least 10 ft and at most: Charmo 66 ft at 9,000 and 12,000, 82 ft at 18,000, 131 ft at 24,000, 30,000 and 36,000 (30,000 and 36,000: submittals); Clivia 66 ft at 9,000 and 12,000, 131 ft at 18,000 and 24,000; Airy 100 ft at 9,000 and 12,000, 131 ft at 18,000 and 24,000; Polaris 131 ft at every size. The submittals allow more for Charmo and Clivia at 9,000 and 12,000, and for Charmo 18,000; we follow the brochure, which is more cautious. The maximum height difference is in the technician’s corner.
At least 18 in (45 cm) above any surface, for snow and defrost water: that is the instruction on the submittals of all four series. The manual also gives a mechanical minimum: 3 cm under the unit for the drain joint, 20 cm for a model with a heating element. The support must carry 4 times the unit’s weight.
The indoor unit measures from 32.88 in (84 cm), for the Charmo 12,000, to 43.9 in (112 cm), for the Polaris 24,000. The to-scale template shows the four series side by side. Also allow for the line: bending radius of at least 10 cm per the manual.
The MOP, the maximum breaker rating, runs from 15 to 30 A depending on the product page. For the four 115 V models, it is 20 A. The MCA / MOP table lists every model.
Only beyond 7.5 m (24.6 ft) of line: the outdoor unit is pre-charged for that length. Then 0.2 oz of R-32 is added per foot, or 0.4 oz for Charmo 30,000 and 36,000, Clivia 24,000, Airy 18,000 and 24,000, Polaris 24,000 (manual; Polaris: brochure and submittals).
The product pages give 51 to 62 dB(A) outside depending on the model; the quietest is the Charmo 9,000. On the Québec.ca scale, 50 dB is moderate rain and 60 a normal conversation. Kinghome does not publish the test conditions: compare models with each other. The Noise tool places each model on the scale.
Per NEEP, each of our Kinghome wall units listed on NEEP has a 68 to 160 W base-pan heater that turns on during defrost and below 1 °C (Polaris 24,000: below -5 °C). The submittals ask for 45 cm under the unit “for snow clearance and defrost runoff”.
At 24,000 BTU/h, at the coldest point published on NEEP: Charmo 12,200 BTU/h at -25 °C (COP 1.63); Clivia 16,000 BTU/h at -30 °C (COP 1.62); Airy 17,000 BTU/h at -30 °C (COP 1.62); Polaris 18,200 BTU/h at -30 °C (COP 1.78). The Charmo 36,000 keeps 21,000 BTU/h at -25 °C. The Deep cold slider gives every size.
The product page gives Region IV, AHRI’s US figure. Canada uses Region V, which is colder and gives a lower number: the Airy 9,000 goes from 11.2 to 8.5 per NEEP. Compare figures from the same region.
For cooling, the ENERGY STAR table gives a rough size by floor area. For heating, we choose the size with you during the free at-home estimate. Note: the six 9,000 BTU/h models do not qualify for LogisVert (why).
