Mini-splits make it easy to add heating and air conditioning to bonus rooms, attics, garages, basements, home offices and any new or previously unconditioned space. Did you know the same technology can be used to heat and cool your entire home as a heat-pump air conditioner? Modern mini- and multi-split heat pumps are increasingly popular as a means to shrink residential carbon footprints and reduce utility costs. Beyond the financial and environmental benefits, heat pumps applied as part of Mitsubishi Electric’s Zoned Comfort Solutions® give you reliable, precise control over the conditioning in each room. 

Stay in your comfort zones

Our Zoned Comfort Solutions use intuitive smart controls and an outdoor condensing unit connected to one or more indoor units via refrigerant piping. Each ducted or ductless indoor unit serves a designated comfort zone and gives you individual control over each zone’s temperature. 

Your contractor will help you divide your home into comfort zones based upon its layout and how you want to use each space. The family room, kitchen, media room, playroom, bedrooms and other spaces can be kept at temperatures appropriate for specific activities and the time of day. Perhaps you’ll keep your bedroom at a lower temperature when it’s unoccupied during the workday, but then have the system raise the temperature to ensure you’re comfortable prior to bedtime. Mitsubishi Electric’s controls make scheduling and quick temperature adjustments simple. If you have an infrequently used room, you can save energy and money by turning off conditioning for its zone. The outdoor heat pump’s INVERTER-driven compressor varies the system’s capacity to precisely match the zone’s comfort requirements and maintain your set point, or preferred temperature. A single-zone system has one outdoor heat pump connected to one indoor unit while a multi-zone system can support up to eight indoor units.

Solutions for any home, anywhere

Whole-home applications typically require ducted indoor units designed to condition larger zones. A multi-position air handler from Mitsubishi Electric can serve an entire floor like a conventional furnace or boiler but is more efficient and eliminates the need for a gas line or flue vent. Depending on your home’s layout and the level of static pressure in your ducts, your contractor might recommend horizontal-ducted indoor units, which are available in small, medium and larger sizes.

The type and number of units will vary by home. For example, a multi-position air handler could condition your home’s first floor and common living areas while a pair of horizontal-ducted units handle your upstairs bedrooms. Or you could customize comfort for your one-story home with two or three horizontal-ducted units. In whole-home applications, Diamond Contractors® also commonly install ductless indoor units to create smaller comfort zones without adding ductwork (in addition to the larger zones served by the ducted units). Ductless options include ceiling cassettes, wall-mounted units and floor-mounted models.

Zoned Comfort Solutions are purpose-built for heating and air conditioning. In whole-home applications, your contractor will also install complementary systems to satisfy fresh air requirements. Your contractor can add Mitsubishi Electric’s kumo cloud® and kumo station® to coordinate equipment for ventilation, filtration, humidity management and auxiliary heating. kumo cloud works with popular digital assistants and enables you to control your home’s comfort and operation through a mobile app.

Renovate an older home for sustainability

Here’s one of example of what builders can achieve with whole-home heat-pump designs. Atlanta-based builder Elemental Green Homes and mechanical contractor Canton Heating & Air partnered with the Mitsubishi Electric Performance Construction team to renovate a craftsman-style bungalow built in 1925 for superior energy efficiency and indoor air quality. The project team added a new master suite and made substantial improvements to the ranch-style home’s air sealing and insulation before dividing its 1,600 square feet into three comfort zones. A horizontal-ducted SEZ unit conditions the central zone while the adjacent zones each have an EZ FIT® Recessed Ceiling Cassette. This hybrid approach using ducted and ductless equipment resulted in an energy-efficient and comfortable home, several rebates and an EarthCraft certification.
