SZ-4Z-317-2025
4 Zones
Are you looking for a heating and cooling solution that offers efficiency, flexibility, and year-round comfort? The Mitsubishi 4-Zone 42k BTU Ductless System with Hyper-Heat is an advanced climate control solution designed for homeowners who want superior comfort without the need for bulky ductwork. Whether you are looking for a way to heat and cool your entire home or specific areas, this system is an excellent fit for a wide range of applications, including older homes without ducts, new additions, or spaces where traditional HVAC systems struggle to perform efficiently.
This system features an outdoor heat pump, the MXZ-SM42NAMHZ2-U1, which is designed to handle multiple indoor units while delivering reliable heating even in freezing temperatures thanks to Mitsubishi’s Hyper-Heat technology. This means you can stay warm and comfortable even in extreme winter conditions where traditional heat pumps might struggle.
For indoor coverage, a combination of four indoor units ensures optimal temperature control across different zones in your home:
- (2) Ceiling Cassette MLZ-KP09NA2-U1 units – Ideal for bedrooms, home offices, or smaller spaces where you want discreet and effective temperature control without wall-mounted units.
- (1) Wall-Mounted MSZ-GS09NA-U1 – Perfect for home offices, guest rooms, or other compact spaces requiring efficient and quiet operation.
- (1) Wall-Mounted MSZ-GS18NA-U1 – A great choice for larger areas, such as living rooms or open-concept spaces, where you need a more powerful unit to maintain a consistent temperature.
One of the biggest advantages of this ductless system is the customizable zoning feature. Instead of heating or cooling the entire house at once, you can control the temperature in each zone independently, reducing energy waste and lowering utility bills. If you have family members who prefer different comfort levels, this system allows each room to be adjusted individually to their needs.
In addition, Mitsubishi’s advanced inverter-driven technology ensures that the system continuously adjusts to the heating and cooling demands of your home, avoiding temperature fluctuations and unnecessary energy usage, which translates to significant savings on your energy bills. The Hyper-Heat feature also makes sure you get high-performance heating even when outdoor temperatures drop well below freezing.
If you're tired of inefficient window AC units, loud central HVAC systems, or inconsistent heating and cooling in your home, the Mitsubishi 4-Zone Ductless System could be the perfect upgrade. With its year-round comfort, quiet operation, and energy-saving benefits, this system is designed to improve the way you experience climate control in your home. Whether you need reliable heating in the winter or refreshing cooling in the summer, this Mitsubishi system works efficiently to keep your home comfortable no matter the season.
