Mitsubishi Electric | Split System Air Conditioner 4.2kW Cooling 5.4kW Heating | R32 Refrigerant
The Mitsubishi Electric MSZ-AP42VGD is a wall-mounted split system air conditioner rated for 4.2 kW cooling and 5.4 kW heating, using R32 refrigerant for improved energy efficiency. The MSZ-AP42VGD combines a compact indoor unit with an outdoor condenser for both heating and cooling in residential and light commercial applications. It complies with Australian and New Zealand standards and is suitable for rooms up to approximately 40–50 square metres depending on insulation and climate zone.
Homeowners and renovation projects often call for a system that runs quietly and requires minimal maintenance. The MSZ-AP42VGD addresses both concerns with a Dual Barrier Coating on the heat exchanger that resists dust and greasy dirt buildup, and a Quiet Mode setting that operates as low as 26dB in heating mode. Reverse-cycle heating means one unit handles both winter warmth and summer cooling without needing separate appliances. The R32 refrigerant delivers better performance than older R410A systems while reducing environmental harm.
Installers and energy-conscious buyers value the MSZ-AP42VGD for its balance of power and running costs. The full inverter technology adjusts compressor speed to match demand, so the system only works as hard as needed. Wi-Fi control (via optional adapter) allows remote operation from a smartphone, and the unit's streamlined design fits neatly into modern interiors without dominating wall space. Flexible piping runs up to 20 metres let installers position the outdoor condenser away from living areas, reducing noise and visual clutter indoors.
Features
- Quiet Mode operation — runs as low as 26dB in heating mode and 26dB in cooling mode, making it suitable for bedrooms and light-sleep environments without disturbing rest.
- Dual Barrier Coating — reduces dust and greasy dirt buildup on the heat exchanger and facial surfaces, keeping the unit cleaner for longer and simplifying maintenance.
- R32 refrigerant — environmentally friendly with only one-third the global warming potential of R410A, delivering improved energy efficiency and lower operating costs.
- Full inverter technology — adjusts compressor speed to match cooling or heating demand, avoiding energy waste at part-load and extending compressor life.
- Reverse-cycle heating and cooling — single unit provides both year-round climate control, eliminating the need for separate heating and cooling systems.
- Vertical and horizontal vanes — directed airflow control allows fine adjustment of temperature distribution across the room.
- Optional Wi-Fi control — smartphone or tablet app allows remote operation from anywhere with an internet connection (adapter required).
- Compact indoor unit — streamlined design measures 299mm (H) × 798mm (W) × 219mm (D), blending into modern interiors without prominent wall mounting.
- Long piping runs — up to 20 metres between indoor and outdoor units allows flexible installation and placement of the outdoor condenser away from living spaces.
- Anti-allergy enzyme filter — built-in filter traps allergens such as mould and bacteria, improving indoor air quality (optional Plasma Quad Connect air purifier available separately).
Where to use
- Bedroom and quiet zones — the Quiet Mode 26dB operation makes the MSZ-AP42VGD ideal for master bedrooms, guest rooms, and studies where silent or near-silent cooling and heating is preferred.
- Open-plan living and dining areas — the 4.2kW cooling capacity suits rooms of 40–50 square metres; flexible vane control distributes airflow evenly across larger spaces.
- Home office installations — low noise and Wi-Fi control allow comfortable year-round office climate without interruption from fan noise or the need to adjust settings manually.
- Renovation and extension projects — the compact indoor unit fits modern new builds and retrofits where wall space is limited, and long piping runs allow outdoor condenser placement away from the main living area.
- New home construction — the wall-mounted design suits newly built homes where ducting is not available and a simple single-room or multi-zone split system is required.
- Properties with multiple rooms — can be installed as the first of a multi-head system; additional indoor units connect to the same outdoor condenser for staged capacity (check dealer for multi-head capability).
The MSZ-AP42VGD is not suitable for outdoor, exposed, or damp locations; it is a wall-mounted indoor unit only. Do not install in wet areas, bathrooms with steam exposure, or external walls subject to rain or salt-spray conditions. The system requires a licensed electrician for installation and connection to mains power. If outdoor space is severely limited or outdoor condenser placement is impossible, an alternative system design may be required.
