4 Zones
Are you looking for an energy-efficient, year-round comfort solution for your home? The Mitsubishi 4-Zone - 42k BTU Ductless System with Hyper-Heat is designed to provide superior heating and cooling throughout multiple areas of your home, ensuring personalized comfort while maximizing efficiency. This system is perfect for homeowners who need precise climate control in individual zones, whether it’s a larger living space, multiple bedrooms, an office, or even sunrooms and bonus areas that struggle with temperature consistency.
Equipped with the highly reliable MXZ-SM42NAMHZ2-U1 outdoor heat pump, this system delivers powerful heating and cooling performance even in extreme temperatures, thanks to Mitsubishi's Hyper-Heat technology, which ensures efficient heating down to -13°F. This makes it ideal for homes in colder climates where traditional heating solutions may fall short in energy efficiency and reliability.
For zoned comfort, this package includes a combination of four indoor units: a 9,000 BTU MLZ-KP09NA2-U1 recessed ceiling unit that seamlessly blends with your décor while providing quiet, efficient performance, and three 12,000 BTU MSZ-GS12NA-U1 wall-mounted units, which are perfect for bedrooms, common areas, and offices that require independent temperature control. Each indoor unit operates independently, allowing customized temperature settings for different areas of your home—no more uneven heating and cooling or wasted energy in unoccupied spaces.
This Mitsubishi ductless system is an excellent solution for homeowners looking to upgrade from outdated window units, inefficient central HVAC, or struggling with hot and cold spots in their home. Unlike traditional forced-air systems, these ductless units do not require extensive ductwork, making installation hassle-free and more cost-effective. Additionally, with advanced inverter-driven technology, the system adjusts power usage dynamically, reducing energy consumption and lowering utility bills over time.
Picture this: during the summer months, your living room stays cool and comfortable while your home office receives just the right amount of cooling to keep you productive. In the winter, each bedroom remains perfectly warm without overworking the entire system or wasting energy in empty spaces. With Mitsubishi’s innovative technology, you have complete control over your home's comfort—all while enjoying whisper-quiet operation and improved air quality through advanced filtration.
If you’re looking for an efficient, customizable, and high-performance heating and cooling solution, the Mitsubishi 4-Zone Hyper-Heat Ductless System offers the flexibility and savings you need. Whether you are upgrading an aging system, finishing a basement, or adding comfort to a new home addition, this system will transform how you experience comfort in your home.
