KINGHOME Charmo R32 Wall-Mounted Heat Pump | 9000 BTU 220V

A compact wall-mounted heat pump, designed for the precise comfort of residential rooms in Quebec

The KINGHOME Charmo R32 Wall-Mounted Heat Pump | 9000 BTU 220V is aimed at homeowners seeking an efficient, discreet solution well-suited for small to medium-sized rooms: master bedroom, enclosed office, condo, back extension, rental unit, small living room, or well-insulated living area. At AirGreen, we often see this type of need in residential projects in Montreal, Laval, Longueuil, on the North Shore and the South Shore: the client doesn't necessarily want to air-condition the entire house with a larger unit, but they want stable, quiet, and reliable comfort in a specific area.

This 9,000 BTU KINGHOME Charmo model combines several important features for the Quebec market: operation with R-32 refrigerant gas, ENERGY STAR® certification, ENERGY STAR® Cold Climate certification, heating down to -25 °C, WiFi included, 220V power supply, rotary compressor, base heater, compressor heater, and well-maintained heating capacity at low temperatures. According to the manufacturer's technical sheet, the indoor model is KW09HQ19CDI and the outdoor model is KW09HQ19CDO, with AHRI number 217903552 and ENERGY STAR® ID 4514229.

A well-targeted 9,000 BTU capacity: neither too low, nor unnecessarily oversized

A common mistake when choosing a wall-mounted heat pump is to automatically aim for a higher capacity, thinking that a larger unit will always yield better results. In reality, an improperly sized unit can lead to excessively short cycles, less effective dehumidification, uneven temperature, and premature wear of certain components.

The KINGHOME Charmo R32 9,000 BTU is interesting because it targets a very specific use: providing stable comfort in an area where a 12,000 BTU unit would sometimes be excessive. In several installations carried out by AirGreen in Montreal condos, Longueuil townhouses, or extensions on the South Shore, we have seen that correct sizing often makes more difference than simply choosing the brand.

This model offers a nominal cooling capacity of approximately 9,100 BTU/h, with a maximum capacity of 10,300 BTU/h. For heating, the technical sheet indicates a nominal capacity of 10,000 BTU/h, with a maximum capacity of 13,136 BTU/h. This margin is particularly useful when the room rapidly loses heat, for example, in an office above a garage, a bedroom exposed to the wind, or a room with large windows.

Heating down to -25 °C: an essential feature for Quebec

In Greater Montreal, a wall-mounted heat pump must not only perform well in air conditioning. It must also offer credible heating during cold periods. The KINGHOME Charmo R32 is designed to operate in heating mode down to -25 °C, which makes it relevant for several residences where one wishes to reduce the use of electric baseboards, improve the comfort of a cold room, or add an efficient heating source in a difficult-to-balance area.

At -8 °C, the technical sheet indicates a heating capacity of 9,600 BTU/h. At -15 °C, it still indicates 7,600 BTU/h. This data is important because it allows a better understanding of what the unit can actually deliver when the temperature drops, instead of relying solely on the displayed nominal capacity.

In our installations, this nuance matters a lot. For example, in a semi-detached house in Laval, a back room poorly served by the central system can remain uncomfortable in winter even if the main heating works well. A well-positioned 9,000 BTU wall unit can then provide very significant local comfort, especially if the indoor location is chosen with care.

R-32, energy efficiency and Cold Climate certification

R-32 is a refrigerant increasingly present in modern heating and air conditioning systems. It allows for an efficient design, with generally optimized refrigerant charge and good thermal performance. For this model, the technical sheet mentions a factory charge of 18.7 oz and an additional charge of 0.2 oz/ft beyond the applicable pre-charged length.

The KINGHOME Charmo R32 also displays solid efficiency data for its category. The technical sheet notably indicates:

• SEER2: 20.5
• HSPF2: 8.8
• EER: 3.6 W/W
• COP: 3.8 W/W

These figures must be interpreted in a real context: room orientation, insulation, air infiltration, piping length, installation quality, regular maintenance, and usage settings. An appliance that is efficient on paper can be disappointing if the installation is poorly executed. Conversely, a well-planned HVAC installation often leads to more stable performance, better comfort, and fewer service calls.

Quiet operation for bedrooms, offices, and condos

Sound level is often underestimated when purchasing a wall-mounted heat pump. However, in a bedroom or office, a few decibels can make a noticeable difference. The KINGHOME Charmo R32 stands out with an indoor sound level that drops to 24 dB(A) in Sleep mode, according to the technical sheet. Indicated levels vary depending on fan speed:

• Sleep: 24 dB(A), 159 CFM
• Low: 27 dB(A), 194 CFM
• Medium: 32 dB(A), 230 CFM
• High: 37 dB(A), 282 CFM
• Turbo: 41 dB(A), 353 CFM

For a bedroom in Montreal, a home office in Boucherville, or a small family room in Terrebonne, this type of sound range allows the unit to be adjusted according to the time of day. The quieter mode is useful at night, while higher speeds can be used to quickly reach the desired temperature after a prolonged absence.

The outdoor unit, for its part, displays a sound pressure level of 51 dB(A). In dense residential areas, such as certain neighborhoods in Montreal, Longueuil, or Laval, the location of the outdoor unit must be chosen taking into account the neighborhood, windows, balconies, municipal regulations, and accessibility for maintenance.

Compact dimensions and real installation constraints

The indoor unit measures approximately 32 7/8 in wide, with a depth of about 7 7/8 in and a height of about 10 53/64 in according to the technical sheet. The outdoor unit is also compact, with an indicated width of approximately 28 13/16 in, a height of about 21 27/32 in, and a depth of about 12 13/64 in.

These dimensions facilitate integration into various residential contexts, but they do not replace a real on-site analysis. A successful installation depends on several details:

• the available space above and around the indoor unit;
• the possible path of refrigeration pipes;
• the distance between the indoor and outdoor units;
• access to the electrical panel;
• condensate drainage;
• the installation height of the outdoor unit;
• the presence of snow, ice, balcony, fence, terrace or pedestrian walkway;
• the aesthetics of the outdoor casing.

The technical sheet indicates that the outdoor unit must be placed at least 18 in above surfaces to allow for snow clearance and drainage during defrost cycles. This point is particularly important in Quebec. An outdoor unit placed too low can become obstructed after snow accumulation, which reduces its efficiency and can cause operational problems.

1/4 – 3/8 piping, 220V power supply, and 15A protection

Technically, the KINGHOME Charmo R32 uses 1/4 inch piping for the liquid line and 3/8 inch for the gas line. The minimum indicated piping length is 10 ft, while the maximum length is 100 ft, with a total maximum height difference of 60 ft. These parameters offer some flexibility, but they must be strictly respected.

The electrical supply is 208-230V / 60Hz / 1 phase, with an MCA of 10A and an MOP of 15A. In many residential projects, this type of configuration can simplify electrical integration, but the panel status, available circuits, wire path, and applicable standards must always be validated.

At AirGreen, we pay particular attention to these details because they directly influence long-term reliability. A good installation is not limited to a unit perfectly aligned on the wall. It must include clean, safe, and durable execution: precise drilling, adequate drain slope, mechanical protection of lines, serious vacuum pull, leak test, complete startup, and clear explanation to the customer.

Included functions: WiFi, I-Feel, self-cleaning, and 8 °C heating

The KINGHOME Charmo R32 includes several useful everyday functions. The included WiFi allows remote management of the device, a tangible advantage for homeowners who want to adjust the temperature before arriving home or monitor usage in a dwelling.

The I-Feel function can improve comfort perception by taking into account the temperature near the remote control, rather than just the temperature near the wall unit. In certain rooms, especially when the unit is installed above a door or on a side wall, this type of function can help better harmonize the perceived temperature.

The technical sheet also mentions:

• Self Clean
• Forced Defrost
• Soft Start
• Low Voltage Startup
• 8 °C Heating
• infrared remote control YBE1FBF included

The 8 °C heating mode can be useful in certain contexts, for example, to maintain a minimum temperature in a less used room. It is not a universal solution for all buildings, but in some well-defined scenarios, this function can help prevent excessive cooling of an area.

Concrete example: a typical installation in a Montreal condo

A frequent case at AirGreen concerns condos where the client wants to improve the comfort of a bedroom or office without modifying the entire existing system. In a condo located in a medium-sized building in Montreal, the challenge is not only to choose a wall-mounted heat pump of appropriate capacity. It also involves managing co-ownership constraints, the permitted location for the outdoor unit, noise, exterior aesthetics, piping distance, and the possibility of properly draining condensate.

For a unit like the KINGHOME Charmo R32 9,000 BTU, we generally aim to position the indoor unit to promote natural air distribution, without blowing directly onto the bed, desk, or a resting area. Outside, we validate the height, support, clearances, and snow protection. The desired result is simple: a discreet, durable, easy-to-maintain, and comfortable installation for daily use.

Concrete example: a cold room in a Laval house

In Laval, we often encounter houses where a room above the garage, a back extension, or a closed office remains colder than the rest of the house. The main system may be functional, but insufficient for this particular area. In this type of situation, a 9,000 BTU unit may be more logical than a larger appliance, especially if the room does not have a large surface area.

Choosing a Cold Climate model then becomes relevant. The client is not just looking for air conditioning in the summer; they also want real heating support during cold periods. A well-sized installation can reduce discomfort, improve room usage, and avoid overheating the rest of the house to compensate for a single problematic area.

Mistakes to avoid with a 9,000 BTU wall-mounted heat pump

Even a good product can yield poor results if certain mistakes are made. Here are the points we pay particular attention to during an HVAC installation:

1. Installing the indoor unit too close to the ceiling or an obstruction
   Insufficient clearance hinders airflow and complicates maintenance.
2. Placing the outdoor unit too close to the ground
   In Quebec, snow and ice can quickly become a problem if proper clearance is not maintained.
3. Underestimating condensate drainage
   An improper slope or drain path can cause leaks, odors, or damage.
4. Choosing the wrong capacity
   An oversized unit can be uncomfortable, while an undersized unit will run too long.
5. Neglecting access for HVAC maintenance
   Filters, indoor unit, outdoor unit, and connections must remain accessible.
6. Comparing only the initial price
   The true cost includes installation quality, warranty, after-sales service, and durability.

Warranty and peace of mind

The product page indicates a 12-year compressor and 12-year parts warranty, with 0 years labor by default, as well as a possible additional warranty. The manufacturer's technical sheet mentions a standard warranty of 7 years parts and compressor, which can be extended to 12 years parts and compressor after registration, according to applicable conditions. This distinction is important: warranty terms may depend on registration, the distributor, compliant installation, and manufacturer conditions.

At AirGreen, we clearly explain these points before installation. We believe that a client must understand not only what is covered, but also how to get service if a problem arises. Our team supports clients after installation, whether for maintenance, diagnosis, operational questions, or labor warranty options.
