4 Zones
Are you looking for an ultra-efficient, year-round comfort solution that delivers precise heating and cooling for multiple rooms in your home without the need for bulky ductwork? The Mitsubishi 4-Zone 42k BTU Ductless System with Hyper-Heat is the perfect choice for homeowners who want exceptional comfort, energy efficiency, and flexibility. Whether you're upgrading your existing HVAC system, finishing a basement, renovating an older home without central ducts, or adding climate control to specific rooms, this system provides individualized comfort in four different zones while maintaining whisper-quiet operation.
Featuring the MXZ-SM42NAMHZ2-U1 outdoor heat pump, this system ensures reliable heating and cooling even in harsh winter conditions, thanks to its advanced Hyper-Heat technology. Unlike traditional heating systems that struggle in extreme cold, this unit can maintain warmth efficiently—even when outdoor temperatures drop significantly. This means your home stays comfortable no matter the season, while also reducing overall energy consumption.
The indoor unit combination—MLZ-KP09NA2-U1 (x2), MLZ-KP12NA2-U1, and MSZ-GS15NA-U1—offers customized climate control for different areas of your home. The MLZ-KP models are low-profile ceiling cassettes, discreetly blending into your ceiling without taking up any wall space, making them ideal for bedrooms, living rooms, home offices, or even kitchen areas. The MSZ-GS15NA-U1 wall-mounted unit provides additional coverage, perfect for larger rooms requiring a more powerful heating and cooling capacity. Each unit operates independently, allowing family members to set personalized temperatures in their individual spaces—no more arguments over thermostat settings!
One of the biggest advantages of this system is its energy efficiency. Traditional HVAC systems waste energy heating or cooling unused spaces, but with a zoned ductless setup, you only use energy where it's needed. This translates into lower utility bills while keeping your entire home at the perfect temperature. Additionally, Mitsubishi’s advanced filtration system improves indoor air quality by reducing allergens, dust, and pollutants—ideal for households with allergies or sensitivities.
Whether you're looking to improve comfort in hard-to-condition spaces, lower energy bills, or gain more control over your indoor climate, the Mitsubishi 42k BTU Hyper-Heat Ductless System provides the perfect solution. With reliable year-round comfort, ultra-quiet operation, and superior efficiency, this system is an investment in your home’s comfort and long-term savings.
