Most heat pumps do fine in October. January is what tests them. As the air outside gets colder, a standard unit has less heat to pull from it, and the room it's supposed to warm starts to feel that. A single zone hyper heat pump system is Mitsubishi's answer. You get one outdoor unit and one indoor unit, built to keep heating a room when the weather turns properly cold. Below are the Hyper-Heat single zone models we carry, in every indoor style from wall mounts to hidden ducted units.

What Is a Single Zone Hyper Heat Pump Systems?

Think of a single zone hyper heat pump systems as a cold climate mini split heat pump for one room or area. Mitsubishi calls the technology Hyper-Heat, or H2i. A Mitsubishi hyper heat pump keeps producing heat at outdoor temperatures where standard models start losing ground.

It's still a full heat pump, too. In summer it runs the other way and cools the room. Winter heat and summer cooling come from the same equipment.

Why Choose a Mitsubishi Hyper Heat Mini Split

• It keeps heating when it's cold out. That's why people in snowy states usually look at a hyper heat mini split first.
• Inverter-driven compressor. The outdoor unit ramps up and down with demand instead of cycling hard on and off, so the room stays at a steadier temperature.
• It cools as well. The same unit handles hot summer afternoons.
• Quiet indoor units. Most models are easy to sleep next to.
• Separate control for that room. You set the temperature for that space without touching the rest of the house.

Mitsubishi Hyper-Heat Indoor Unit Styles

Every Mitsubishi hyper heat pump in this lineup gets its cold-weather performance from the outdoor unit, so the indoor unit is where you match the room:

• Wall mount: The usual pick for bedrooms, living rooms and offices. It sits high on the wall.
• Designer Series wall mount: A flatter, cleaner-looking wall unit for rooms where looks matter.
• Floor mount: Sits low, so warm air starts near the floor. It also fits under windows or in attic rooms with sloped ceilings.
• One-way ceiling cassette: Recessed into the ceiling and blows air in one direction. Good along a wall or in narrow rooms.
• Four-way ceiling cassette: Also recessed, but spreads air four ways for larger open rooms.
• Mid static slim ducted: Tucked above a ceiling or in a crawlspace, moving air through short ducts. All you see are the grilles.
• Multi-position air handler: Can sit upright or on its side, which helps in closets, attics and basements.

Hyper-Heat vs Standard Single Zone Systems

Where you live mostly decides this. If your winters are mild and freezing nights are rare, a standard unit from our single zone heat pump systems collection will handle the room. If you get long stretches below freezing, or you want the heat pump to be the main heat source for that space, a single zone hyper heat pump systems is the safer pick. It's a cold climate mini split at heart, and you notice the difference on the coldest days.

How to Choose a Cold Climate Mini Split

• Size it to the room. Square footage, ceiling height, insulation and windows all change the BTU rating you need. Too big causes trouble as well, since the unit short-cycles.
• Pick the indoor style. Think about where it will go and how visible you want it to be.
• Count the rooms. One space is a single zone job.

Need heat in several rooms from one outdoor unit? Mitsubishi multi-zone heat pump systems come in Hyper-Heat versions too.
