A 24,000 BTU wall-mounted solution designed for large Quebec spaces

For an open-plan house, a spacious condo, a duplex, a local business, or a main area that is difficult to stabilize, a 24,000 BTU wall-mounted heat pump can make a very tangible difference in daily comfort. The KINGHOME Charmo R32 | 24000 BTU Wall-Mounted Heat Pump stands out as an interesting option for homeowners seeking a solution that is both high-performing in air conditioning, useful for supplemental or primary heating depending on the configuration, and eligible for a significant provincial subsidy.

At AirGreen, we primarily evaluate it for projects where a 12,000 or 18,000 BTU unit would be insufficient: large open-plan living rooms, main floors with higher ceilings, retail businesses, professional offices, dwellings with high sun exposure, or replacing an old wall-mounted system that no longer meets the building's actual demands. Its 24,000 BTU capacity, R-32 refrigerant gas, ENERGY STAR® Cold Climate status, included WiFi, and a LogisVert subsidy announced at $2,304 make it a machine to seriously consider for many HVAC installations in Montreal, Laval, Longueuil, on the North Shore and the South Shore.

Heating capacity adapted to Quebec's real winters

The technical specifications of this KINGHOME Charmo indicate a heating capacity down to -25 °C, with a nominal heating power of 24,000 BTU. More precisely, the technical documentation indicates a heating capacity of 22,400 BTU at 8.3 °C, 19,200 BTU at -8.3 °C, and 16,800 BTU at -15 °C. These figures are important as they provide a better understanding of the unit's actual performance when the temperature drops below zero.

In several homes in the Montreal area, we see the same scenario: clients want to reduce their electric baseboard usage, stabilize a large open room, and avoid temperature differences between the living room, kitchen, and dining room. A 24,000 BTU wall-mounted heat pump alone won't solve everything in a highly compartmentalized house, but in a well-cleared area, it can offer very interesting performance.

During a well-planned HVAC installation, the placement of the indoor unit becomes as important as the choice of machine. A 24,000 BTU wall-mounted unit moves a lot of air. Therefore, it should be avoided placing it directly above a sofa, facing a kitchen table, or in a too-narrow hallway. The KINGHOME Charmo 24,000 BTU has automatic vertical and horizontal louvers, which facilitates air distribution, but positioning analysis remains essential.

R-32, included WiFi, and seasonal efficiency: what changes daily

This KINGHOME wall-mounted heat pump uses R-32 refrigerant, increasingly present in modern wall-mounted systems. This gas is valued for its energy efficiency and its more favorable environmental profile than several older refrigerants used in previous generations of heat pumps.

The included WiFi is also a practical advantage. For many AirGreen clients, especially those who own a multiplex, a rental condo, an office, or a secondary residence, remote control quickly becomes a useful tool. It allows you to:

  • reduce the temperature when the space is unoccupied;
  • preheat or pre-cool before arrival;
  • avoid leaving the appliance running unnecessarily;
  • adjust comfort without being on site;
  • better manage heatwaves or intense cold periods.

The technical documentation also indicates integrated functions such as I-Feel mode, self-clean, forced defrost, soft start, low voltage startup, and 8 °C heating. These details are often overlooked during a quick purchase, but they can make a real difference in daily use, especially in a climate like that of Greater Montreal.

An ENERGY STAR® Cold Climate certified machine

The KINGHOME Charmo 24,000 BTU is listed as ENERGY STAR® and ENERGY STAR® Cold Climate, with AHRI number 217995506 and ENERGY STAR identifier 4515403. For a homeowner comparing several models, this certification is a reassuring point, as it confirms that the appliance meets recognized performance criteria.

In terms of efficiency data, the technical sheet notably mentions:

  • SEER2: 19
  • HSPF2: 8.5
  • EER: 3.5 W/W
  • COP: 3.6 W/W

These values must be interpreted in the context of the project. A well-installed, properly sized, and well-maintained wall-mounted heat pump will generally yield better results than a more expensive machine installed in the wrong place or with poorly prepared piping. At AirGreen, we often emphasize this point: the final performance depends on the product, but also on the quality of the HVAC installation.

LogisVert subsidy: a significant financial advantage

According to the information currently displayed for this product, the announced provincial LogisVert subsidy is $2,304. For a 24,000 BTU wall-mounted heat pump, this amount can strongly influence the net cost of the project.

However, we always remind our clients that final eligibility depends on the program's conditions, the building, the applicant, the invoice, the installed model, and the criteria in effect at the time of application. At AirGreen, we prepare clear invoices, with the indoor and outdoor models, relevant numbers, and necessary information to facilitate the client's process.

For homeowners in Montreal, Laval, Longueuil, in Montérégie, on the North Shore or the South Shore, this subsidy can make the KINGHOME Charmo 24,000 BTU particularly competitive compared to other machines of comparable capacity.

Technical installation: the details that prevent problems later

A 24,000 BTU wall-mounted heat pump requires a serious installation. It's not just a matter of fixing a unit to the wall and connecting two pipes. Technical information indicates 1/4 in - 1/2 in piping, 208-230V / 60Hz / 1Ph power supply, a minimum circuit ampacity of 15A, and a maximum overcurrent protection of 20A. The recommended power wire is indicated as 12/3 AWG, with 14/4 AWG interconnection.

These details must be validated on-site, especially during a replacement. In older homes in Montreal, multiplexes in Longueuil, bungalows in Laval, or properties on the South Shore, we sometimes find existing circuits that do not perfectly match the needs of the new system. In other cases, the old outdoor location does not offer the necessary clearances, or the existing line cannot be reused without thorough verification.

At AirGreen, when reuse of piping is considered, we check the condition of the lines, diameter, routing, insulation, access, and compatibility with the new refrigerant. An apparent saving can become costly if the lines are contaminated, crushed, too long, poorly insulated, or inadequately protected.

Outdoor Clearances: A Crucial Point for Snow and Defrosting

The technical documentation specifies that the outdoor unit must be placed a minimum of 18 inches above surfaces to allow for snow clearance and defrost water drainage. This is a particularly important point in Quebec.

In winter, a heat pump produces water during defrost cycles. If the unit is installed too low, ice accumulation can block airflow, strain the compressor, increase noise, reduce efficiency, and, in some cases, cause shutdowns. This is why we often recommend a wall mount or a sufficiently high ground mount, depending on the building, access, aesthetics, and available structure.

Clearances around the outdoor unit must also be respected. A unit placed too close to a wall, fence, hedge, or balcony can lose efficiency. For a 24,000 BTU machine, the volume of air discharged is considerable; therefore, the necessary space must be provided for it to breathe properly.

Sound level: what you need to know before choosing the location

The outdoor sound pressure level is indicated at 58 dB(A). Indoors, the data sheet mentions levels varying according to fan speed, from 36 dB(A) in Sleep mode up to 51 dB(A) in Turbo mode. Airflow can reach 677 CFM in Turbo mode.

In a living room or open area, these values are generally acceptable when the intended use is well understood. However, for a bedroom, a very quiet office, or a room where the unit would be placed too close to occupants, a 24,000 BTU capacity may be excessive. This is why an on-site evaluation is important.

We have seen clients request a very large unit, thinking it would automatically be more comfortable. In some cases, this is true. In others, an overly powerful machine in a small area can create short cycles, too direct airflow, or less uniform comfort. The right choice depends on the room's volume, insulation, building orientation, number of floors, internal openings, and lifestyle habits.

Real example: an open area difficult to stabilize in Longueuil

In a recent project in Longueuil, a client had a main area with a connected living room, kitchen, and dining room, but their old 18,000 BTU wall-mounted air conditioner was no longer sufficient during heatwaves. The building had large southwest-facing windows and a mezzanine that accumulated heat.

After analysis, a 24,000 BTU wall-mounted unit became more logical than a simple replacement with identical capacity. The main challenge was not just power: it was necessary to avoid directing airflow towards the kitchen table, maintain reasonable access for HVAC maintenance, provide a clean outdoor line, and position the compressor in a location that allowed for good winter clearance.

This is precisely the kind of situation where a KINGHOME Charmo 24,000 BTU can be relevant. The machine offers enough capacity to treat a large area, but it must be installed precisely to avoid discomfort due to misdirected airflow.

Real example: replacement in a multiplex in Montreal

In several multiplexes in Montreal, owners are looking to replace an old wall-mounted heat pump installed 12 to 18 years ago. The constraints are often the same: narrow rear access, visible line passage, electrical supply to be validated, outdoor unit placed in a shared courtyard, and the need to limit noise pollution.

For this type of project, the KINGHOME Charmo 24,000 BTU can be a good candidate when a spacious main dwelling needs heating or cooling. However, we pay particular attention to the exterior finishing: piping protection, drain slope, penetration sealing, clearance around the compressor, and strength of the support. A clean installation instills confidence in the owner, but it also facilitates after-sales service.

Common mistakes to avoid with a 24,000 BTU wall-mounted heat pump

A device of this capacity can yield excellent results, but certain errors frequently occur when the installation is not well planned.

Choosing solely based on BTU count

BTU alone is not enough. Two houses of the same size can have very different needs. A well-insulated house with an open plan can be easy to treat. Another, older house, with multiple divisions, air leaks, and significant sun exposure, will require a different approach.

Installing the indoor unit too close to an obstruction

The documentation indicates minimal clearances around the indoor unit. These clearances are not just aesthetic recommendations. They help the appliance correctly draw in and distribute air. A tall piece of furniture, a beam, a side wall that is too close, or a low ceiling can hinder performance.

Neglecting drain flow

A poorly sloped or improperly protected drain can cause water leaks. At AirGreen, we pay particular attention to the drain's path, especially in installations where the indoor unit is far from the exterior wall.

Placing the compressor too low

In Quebec, this point is critical. Snow, ice, and defrost water must be anticipated from the moment of installation. An outdoor unit placed too low can become problematic from the first serious winter.

Forgetting maintenance

Even a good heat pump loses efficiency if the filters, fan, evaporator, or condenser are dirty. Regular HVAC maintenance helps maintain performance, reduce odors, limit noise, and extend the system's lifespan.

Why choose AirGreen for this installation

At AirGreen, we install wall-mounted, central, and multi-zone systems in various contexts: single-family homes, condos, multiplexes, businesses, offices, and rental properties. Our approach is based on a concrete analysis of the building rather than a generic recommendation.

For a KINGHOME Charmo R32 24,000 BTU wall-mounted heat pump, we notably verify:

  • the area and configuration of the space;
  • ceiling height;
  • solar orientation;
  • the condition of the electrical panel;
  • the possible routing of the piping;
  • the location of the outdoor unit;
  • the necessary clearances for snow;
  • future access for service and maintenance;
  • the interior and exterior aesthetic finish;
  • potential eligibility for available subsidies.

We provide a clear offer before work begins. Clients know what is included, what might incur an additional cost, and how the project will be executed. This transparency is essential, especially for a 24,000 BTU installation where technical details can influence the final cost.

A Serious Wall-Mounted Heat Pump for a Well-Evaluated Project

The KINGHOME Charmo R32 Wall-Mounted Heat Pump | 24000 BTU is particularly suitable for owners who want a robust wall-mounted solution for a large area, with good heating capacity, Cold Climate ENERGY STAR® certification, WiFi included, R-32 refrigerant, and a LogisVert subsidy announced at $2,304.

It is not intended for all spaces. In a small room or a highly compartmentalized dwelling, another configuration might be more appropriate. But for an open-concept area, a large ground floor, a commercial space, or a replacement of similar capacity, it deserves serious consideration in the comparison.
