Comfort and control in any room.

Cool comfort in any room

No matter what temperature the outdoor thermometer reads, Dead River Company provides year round comfort in any weather. A Mitsubishi Electric ductless air conditioner requires no ductwork, making it quick and easy to install.

This unit:

  • Uses only the exact amount of energy needed to maintain comfort
  • is up to 40% more efficient than window units
  • can be installed just about anywhere in a room
  • is virtually silent and improves air quality
  • can come with heat pump technology, so the same unit can be used to warm the room during the cold winter months

Mitsubishi Electric gives you precise temperature control even in spaces you thought would be impossible to fix. Thanks to their advanced INVERTER-driven compressor technology and smart, easy-to-use controls, you can achieve consistent temperatures throughout the room as you are saving energy all year long, year after year.

With a Mitsubishi Electric unit, any room in your house or your entire home can transform from an oasis of cool, dry comfort in the summer to a warm and cozy hangout in the winter.

Customer Testimonials

A Dead River customer in New Hampshire had this to say about their new Mitsubishi Electric Air Conditioner:

"Thanks for your assistance in getting our house air conditioned last week!! The 2 ton Mitsubishi split unit that your engineer recommended is working out just great. The unit is extremely quiet and the house cools down quickly. [We] appreciate your willingness to mount it where we requested in the kitchen, rather than the "easy" route on an outside wall in the Great Room. I know it was a little more work to mount it on an inside wall, but we are so much happier with the end result. Your techs Danny and James were professional and should be commended for their good work."

What's 'ductless'?

Ductless mini-split heating and cooling systems are a smart alternative to central, forced air systems, as they do not require the use of air ducts.   Read more about ductless systems.
