Mitsubishi

Mitsubishi Electric, a Japanese company, makes them. In the United States they are sold by Mitsubishi Electric Trane HVAC US (METUS for short), a 50/50 joint venture between Mitsubishi Electric and Trane Technologies. The venture started in 2018 and is based in Suwanee, Georgia.

Don’t confuse it with Mitsubishi Heavy Industries. That is a separate, competing company that also sells mini-splits under the three-diamond logo, with a different product line.

• Inverter everything. Mitsubishi builds its systems around variable-speed inverter compressors, which ease up and down like a foot on the gas instead of slamming on and off.
• Ductless roots. Mitsubishi brought its Mr. Slim ductless unit to U.S. homeowners in 1982, long before anyone in Austin was hanging mini-splits on bonus room walls.
• Cold-weather heat. Mitsubishi says its Hyper-Heating INVERTER (H2i) systems deliver 100% of rated heating capacity at 5°F and 80% at -13°F.
• Room-by-room control. Single-zone and multi-zone systems heat or cool one room without running the whole house.
• Diamond Contractor program. Mitsubishi trains and qualifies installers through this program. Mitsubishi says homeowners who use a Diamond Contractor get a 12-year parts and compressor warranty on qualifying single-family installs registered within 90 days.

In commercial HVAC, Trane is one of Mitsubishi Electric’s biggest competitors. Since 2018 the two have also shared a U.S. company for ductless and VRF equipment, which is why a Mitsubishi indoor unit can arrive with a Trane or American Standard name on the front.

• Hot rooms. Upstairs bonus rooms, garages turned into gyms, sunrooms and additions are where a central system runs out of reach and a ductless head earns its spot on the wall.
• Humidity. An inverter system runs long and slow, and many Mitsubishi models add a dry mode for muggy months. See our humidity resources.
• Freezes. When Camp Mabry hit 7°F during Winter Storm Uri in 2021, many standard heat pumps lost capacity fast. Mitsubishi’s Hyper-Heating models are built for that kind of cold. Read can a heat pump keep up with a Texas freeze.
• Zoning without ducts. If the family fights over one thermostat, a head in each room can settle it. See why mini-splits are a good alternative to zoning.

• Single-zone. One outdoor unit and one indoor head. The usual answer for a garage, sunroom or bonus room.
• Multi-zone. One outdoor unit feeding several indoor heads, each with its own control, for a few rooms that want different temperatures.
• Ducted inverter. A hidden air handler in the attic or a closet feeds several rooms through short ducts, for anyone who doesn’t want a unit on the wall.
• Hyper-Heating models. Worth the step up if the room has to stay warm through a freeze.

Size each room on its own. An oversized head cools fast, shuts off before it pulls the moisture out and leaves the room clammy; an undersized one never stops running. Ask how the load was figured for each space, and where each condensate line will drain.

Is Mitsubishi Electric the same as Mitsubishi Heavy Industries?
No. They are separate, competing companies that both sell mini-splits under the Mitsubishi name.

Does Trane make Mitsubishi mini-splits?
No. Mitsubishi Electric makes them. Trane Technologies and Mitsubishi Electric share a 50/50 U.S. joint venture that sells Mitsubishi products, including versions co-branded Trane and American Standard.

What is a Mitsubishi Diamond Contractor?
An installer that has met Mitsubishi Electric’s training and qualification requirements. Mitsubishi offers extended warranty coverage on qualifying installs by Diamond Contractors. Gold Eagle is one.

Will a Mitsubishi heat pump work in a Texas freeze?
The Hyper-Heating models are built for it. Mitsubishi says they keep 100% of rated heating capacity at 5°F and 80% at -13°F; Camp Mabry’s low during Uri was 7°F.
