Description
To climate control a room with a wall-mounted split: 3,612 frigories/h (4.2 kW) nominal cooling capacity. Mitsubishi Electric MSZ-AY42VGK + MUZ-AY42VG includes one indoor and one outdoor unit; it is not a system for distributing cold independently between multiple rooms. Check the load of the room and the installation space before choosing. Installation not included.
The choice of power depends on the space, its orientation, and its insulation. A split unit located in one room does not guarantee the same temperature in adjacent rooms; to serve multiple rooms, it is advisable to consider a multisplit system or a ducted installation.

Load calculation and documentation
Outdoor unit: MUZ-AY42VG. Check PCB and maintenance.
Additional charge by length: 20 × (L − 7.5) g, only if L exceeds 7.5 m and does not exceed 20 m.
L is the actual one-way distance between interior and exterior, not the sum of the liquid and gas pipes. Outer diameters, in liquid / gas order. Refrigerant piping; not cable section or inner diameter.
Data to prepare the installation, not an instruction for recharging due to a fault. The charge must be verified and carried out by a qualified installer according to the PCB, the inspection, and the equipment manual; do not add refrigerant solely due to a lack of cooling.

Questions about MSZ-AY42VGK + MUZ-AY42VG
How many frigories does it have and how many rooms is it suitable for?
This unit has a nominal cooling capacity of 3,612 frigories/h (4.2 kW) and a single indoor unit (MSZ-AY42VGK). It is designed for a room or an open space that has been sized as such. It is not equivalent to a 2x1 for two closed rooms.
Is it an option if I am looking for an air conditioning unit with 3,500 frigories?
The exact figure for this combination is approximately 3,612 frigories/h nominal (4.2 kW), above 3,500. If the calculation for your room requires at least 3,500 frigories/h, also compare the capacity at the expected outdoor temperature and the margin indicated by the installer.
Is it suitable for a bedroom with a lot of sunlight?
It can be useful, but it's important to know how much your bedroom heats up, especially if it gets afternoon sun or is under the roof. If you need a bit more power, compare the Mitsubishi Electric MSZ-AY50VGK + MUZ-AY50VGIt goes from about 3,612 to 4,300 frigories/h. Tell us the square meters and if the ceiling is insulated: we help you choose the power and check the noise of the split for sleeping.
How do I know if it has enough power for my living room?
To choose the power, you need to consider the size of the living room, how much sunlight it receives, and the insulation. If the living room is spacious or continues to retain a lot of heat, compare the Mitsubishi Electric MSZ-AY50VGK + MUZ-AY50VGIt goes from about 3,612 to 4,300 frigories/h. Tell us the square meters and how much sun it receives, and we will help you choose.
What noise will I have to compare to use it at night?
The technical sheet of MSZ-AY42VGK states 21 / 29 / 34 / 38 / 42 dB(A) of indoor sound pressure in cooling mode. Compare the speed and testing conditions: the lowest value does not describe the noise at full power nor guarantees that level measured at your bed. Do not confuse it with sound power.
Are those frigories what it consumes in electricity?
No. 3,612 frigories/h (4.2 kW) describe cooling capacity, while the technical sheet states 1.3 kW of nominal electric power in cooling for this combination. Actual consumption varies with load, temperature, settings, and operating hours; that figure is not a fixed monthly bill.
What does MSZ-AY42VGK + MUZ-AY42VG include?
1 × MSZ-AY42VGK (indoor unit); 1 × MUZ-AY42VG (outdoor unit); 1 × SH22Q (remote control). The previous composition identifies the units and controls of this offer. The installation is contracted separately.
What measurements should I check before booking the equipment?
Indoor unit · height × width × depth: 299 × 798 × 245 mm. Outdoor unit · height × width × depth: 550 × 800 × 285 mm. These are the dimensions of the indicated components, not the minimum installation space. Also allow for the clearances, connections, and maintenance access required by the manual.
What efficiency does this combination have and what can I compare?
SEER of the set: 7.9. SCOP of the set · average climate: 4.7. Energy class in cooling: A++. Energy class in heating · average climate: A++. Compare the same magnitude, combination, and test climate. These data do not certify the consumption of your home or the performance of another combination.
Is Wi-Fi included or is an accessory required?
Integrated Wi-Fi in the indoor unit, with control via MELCloud. No additional adapter purchase is required. The remote control operates via infrared; the Wi-Fi is built into the unit.
What command does the equipment receive?
Includes 1 remote control: 1 × SH22Q.
Are the decibels in the technical sheet the noise I will hear at home?
Interior sound pressure in cold: 21 / 29 / 34 / 38 / 42 dB(A). Exterior sound pressure in cold: 50 dB(A) in cold. Interior sound power in cold · maximum speed: 57 dB(A). Maintain the indicated speed and mode when comparing. Sound pressure and sound power are different magnitudes; the perceived noise also depends on the room and the installation.
When to choose AY42 instead of AY35?
When the room requires more capacity than the 3.5 kW nominal of the AY35. The AY42 offers 4.2 kW in cooling and maintains the same interior width of 798 mm; the increase is in capacity, not in the number of rooms served.
Is the AY42 as quiet as the AY25?
They do not have the same minimum published level. In cold mode, the AY42 starts at 21 dB(A) and the AY25 at 18 dB(A), depending on the fan speed. If it is going to be placed in a bedroom, it is advisable to compare capacity and noise, not just the appearance.
Do I need the AY42 or should I switch to the AY50?
The AY50 offers 5.0 kW nominal in cooling compared to 4.2 kW of the AY42. Compare the space demand, especially with large windows or strong solar exposure; neither converts a single indoor unit into independent climate control for multiple rooms.
