KINGHOME Charmo R32 Wall-Mounted Heat Pump | 9,000 BTU 115V
A compact, efficient wall-mounted heat pump designed for small spaces in Québec
The KINGHOME Charmo R32 9,000 BTU 115V wall-mounted heat pump is aimed at homeowners looking for a heating and cooling solution that is precise, quiet and well suited to small and mid-sized residential spaces. In a condo, a main bedroom, a home office, a rental unit, a house extension or a room that's hard to keep comfortable with the existing central system, this model offers an attractive combination: 115V power, R-32 operation, certified ENERGY STAR® Cold Climate performance, heating down to -25 °C, included WiFi and a discreet wall-mounted format.
At AirGreen, we often see this kind of need during our HVAC installations in Montréal, Laval, Longueuil, on the North Shore and the South Shore. The client isn't always looking to cool an entire house. Sometimes they want to fix one very specific concern: a room that gets too hot in summer, a home office that becomes uncomfortable, a unit poorly served by the main heating system, or a bedroom above a garage that loses its heat quickly in winter. In these situations, a 9,000 BTU wall-mounted heat pump can make far more sense than an oversized unit.
The KINGHOME Charmo R32 9,000 BTU 115V stands out for its well-balanced technical profile. Its indoor unit is the KW09HQ19CAI and its outdoor unit is the KW09HQ19CAO. According to the manufacturer's technical data, the unit offers a nominal cooling capacity of 9,100 BTU/h, a nominal heating capacity of 10,000 BTU/h, AHRI certification 218679826, ENERGY STAR certification and a Cold Climate Energy Star Heat Pump classification. The technical document also lists a SEER2 of 20.5 and an HSPF2 of 8.8. ENERGY STAR lists an EER2 of 11.9.
Why a 9,000 BTU model can be the right choice
A common mistake when choosing a wall-mounted heat pump is to assume that a bigger unit will automatically deliver better comfort. In reality, a system that's too big for the room tends to short-cycle. The result can be less comfortable: fluctuating temperatures, poorer humidity control, premature wear on some components and more noticeable noise.
A 9,000 BTU model is often a good fit for:
- a closed bedroom;
- a home office;
- a small condo;
- a room above a garage;
- a bachelor apartment;
- an annex or an addition;
- a small, well-insulated open area;
- a zone that complements an existing central system.
On many AirGreen projects in Greater Montréal, clients reach out to us after getting recommendations that were far too general. For example, a homeowner in Laval initially wanted to install an 18,000 BTU unit in a closed space of about 350 to 450 sq. ft. After looking at the insulation, sun exposure, windows and how the room is actually used, a more moderate capacity turned out to be a much better fit. The goal isn't to install the biggest unit possible; the goal is to install the right unit, in the right place, with a clean and durable setup.
A practical advantage: 115V power
The KINGHOME Charmo R32 9,000 BTU 115V can be a real advantage in some buildings, especially when electrical access is limited or when a client wants to avoid heavier electrical work. It runs on 115V/60Hz/1Ph power, with a minimum circuit ampacity of 19A and maximum overcurrent protection of 20A, according to the technical documentation.
That doesn't mean no electrical check is needed. At AirGreen, we always verify the condition of the panel, circuit availability, wiring compliance and the building's constraints. In some older units in Montréal, especially in plexes, converted condos or buildings where the electrical panel is already heavily loaded, this step is essential. A reliable HVAC installation always starts before the unit is even mounted on the wall.
Heating down to -25 °C: an important criterion for the Québec climate
The Charmo R32 9,000 BTU 115V is designed to keep heating down to -25 °C. For a client in Longueuil, Boucherville, Terrebonne, Blainville, Repentigny, Saint-Bruno, Brossard or Montréal, that figure really matters. The Québec climate imposes conditions that are nothing like those of milder markets.
Low-temperature performance is also more nuanced than a simple “heats down to -25 °C” claim. According to the available data, the unit delivers 10,000 BTU/h at -8.3 °C and 7,600 BTU/h at -15 °C. These figures give a better sense of how it behaves in winter. In a well-insulated room, these capacities can be very attractive. In a room with a lot of heat loss, poor airtightness or large windows exposed to the wind, more caution is needed.
That's why AirGreen never recommends a unit based on BTU alone. We look at the room, the building, the orientation, the insulation, the household's habits and the client's goal. An office used all day doesn't have the same needs as a bedroom used only at night. A recent condo doesn't have the same heat loss as a century-old triplex.
R-32: a modern refrigerant better suited to the new generations of equipment
This heat pump uses R-32 refrigerant, which is increasingly common in modern heating and cooling equipment. For clients, the benefit is simple: manufacturers are now building many new platforms around R-32 to improve the performance, efficiency and environmental impact of their systems.
During an installation, the choice of refrigerant also shapes how the work is done. Our technicians follow procedures suited to the type of refrigerant, the pipe diameter, the line length and the system charge. The KINGHOME Charmo R32 uses 1/4 in piping for the liquid line and 3/8 in for the gas line, with a recommended minimum length of 10 feet, a maximum length of 100 feet and a maximum vertical difference of 60 feet, according to the spec sheet.
These details may seem secondary, but they have a direct impact on the quality of the installation. A line that's too short, too long, poorly insulated, poorly protected or poorly evacuated can lead to performance, noise, drainage or reliability concerns. At AirGreen, we pay close attention to the vacuum, the mechanical protection of the lines, condensate drainage and the exterior finish.
Quiet indoors: a strong point for bedrooms and offices
The indoor unit of the KINGHOME Charmo 9,000 BTU runs as low as 24 dB(A) in Sleep mode, according to the documentation. Levels rise gradually with fan speed: about 31 dB(A) at low speed, 34 dB(A) at medium speed, 38 dB(A) at high speed and 43 dB(A) in Turbo mode.
In real life, this can make a big difference. For a bedroom, an office or a room where you take phone calls for work, operating noise becomes as important a comfort factor as temperature. We've already replaced older units in condos in Montréal simply because the client could no longer stand the noise of the indoor unit at night. A recent unit, properly sized and properly installed, can transform the day-to-day experience.
Airflow also varies by mode, from about 159 CFM in Sleep mode to 353 CFM in Turbo mode. This lets you choose between very quiet operation and faster air circulation when the room needs to be cooled or heated more quickly.
Included WiFi, I-Feel function and self-cleaning
Included WiFi has become an important criterion for many clients. It lets you control the wall-mounted heat pump remotely, adjust the temperature before you get home, cut consumption when the room isn't in use and manage comfort around your schedule.
The spec sheet also mentions several built-in features:
- WiFi control;
- I-Feel;
- Self clean;
- Forced defrost;
- Soft start;
- Low voltage startup;
- 8 °C heating.
The I-Feel function can be especially useful, because it reads the temperature closer to where people actually are, depending on the setup. The 8 °C maintenance mode may also appeal to some clients for rarely used spaces, such as a workshop, a spare room or a property used only now and then. It isn't a universal solution, but in some scenarios it can help prevent an excessive drop in temperature while keeping consumption down.
Outdoor installation: clearances, snow and defrost drainage
A good outdoor installation is essential for winter performance. The manufacturer's documentation specifies that the outdoor unit must be installed at least 18 inches above surfaces to allow snow clearance and drainage during defrost cycles. It also lists minimum clearances around the outdoor unit, in particular to ensure proper airflow.
In the Montréal area, this point is very important. An outdoor unit set too low can quickly be affected by snow buildup, ice, runoff or freeze-thaw cycles. At AirGreen, we often recommend a wall bracket or a ground stand that suits the site. The choice depends on several factors: type of foundation, slope of the ground, access for maintenance, noise transmitted to the structure, wind exposure, aesthetics and condo rules.
On a typical project on the South Shore, for example, a client wanted to put the outdoor unit in a narrow corner between a fence and a wall. On paper, the spot looked convenient. On site, we found that the air would have been poorly discharged and that snow buildup would have hampered operation. We moved the unit a few feet, added a more suitable stand and kept a clean finish. The client got a more reliable installation without compromising the exterior look.
Where to install the indoor unit for the best comfort
Choosing the indoor location is just as important as choosing the model. For a 9,000 BTU wall-mounted heat pump, the goal is effective air distribution without creating direct discomfort. A unit placed too close to a bed, a workstation or a couch can blow straight onto the occupants. On the other hand, a unit placed too far from the main area may run longer without reaching the desired comfort.
We generally assess:
- the available height on the wall;
- the clearances around the unit;
- the natural direction of the airflow;
- where the furniture is;
- the distance to the outdoor unit;
- whether the condensate can be drained properly;
- the look of the interior;
- the routing of the piping and wiring.
The documentation shows that the indoor unit is about 32 7/8 in wide, with minimum clearances to respect. These details help confirm whether the chosen wall really works. In some condos or apartments, a few inches can make all the difference between a clean installation and a forced one.
Warranty: 12 years parts and compressor after registration
On the product page, the warranty shown is 12 years compressor, 12 years parts and 6 years labour directly from the distributor, with additional coverage available. The spec sheet also specifies a standard warranty of 7 years parts and compressor, which can go up to 12 years parts and compressor after registration, subject to the applicable conditions.
For the client, it's important to tell apart the warranty on parts, the warranty on the compressor and labour. Many homeowners think a manufacturer's warranty automatically covers every cost in the event of a breakdown, but that isn't always the case. Parts may be covered, while labour is covered for 6 years directly by the distributor, and diagnosis or travel may depend on the contract, the installer and the options chosen.
AirGreen offers additional warranty options based on the client's needs. This transparency avoids misunderstandings and lets you choose protection that matches the peace of mind you're looking for.
LogisVert subsidy: why the indicative amount is $0
On this product page, the indicative LogisVert amount is $0, as of the November 26, 2025 update, because this model is not on Hydro-Québec's list. This means you shouldn't assume a subsidy amount simply because a unit is ENERGY STAR or Cold Climate. Programs change, criteria can vary, and eligibility depends on several factors. Only Hydro-Québec confirms the assistance granted.
At AirGreen, we always recommend checking the information at the time of the quote. For some clients, the final choice of a wall-mounted heat pump may be influenced by subsidy eligibility. For others, the main criterion is rather the 115V power supply, availability, size, ease of installation or how well it fits the space.
In this particular case, the product remains attractive even without a subsidy shown, especially for projects where a compact, quiet, R-32, 115V-compatible unit suits the building better than a more expensive or more complex solution.
Mistakes to avoid before buying a 9,000 BTU wall-mounted heat pump
Before choosing the KINGHOME Charmo R32 9,000 BTU 115V, here are the mistakes we come across most often:
- choosing the capacity based only on floor area, without considering insulation;
- placing the indoor unit for looks only, without thinking about air distribution;
- underestimating the importance of condensate drainage;
- installing the outdoor unit too low relative to the snow;
- overlooking ventilation clearances;
- forgetting to check the electrical panel;
- comparing price alone without comparing installation quality;
- not planning future access for HVAC maintenance.
A durable HVAC installation comes down to many details. A quality unit can give poor results if it's badly installed. Conversely, a well-chosen, well-installed model can deliver excellent comfort for many years.
