Why Go Ductless

Comfort Without Tearing Open Walls

Not every space is built for ductwork — additions, finished basements, older homes, and converted spaces often just don't have anywhere to run it. A Mitsubishi ductless mini-split solves that with independent, room-by-room comfort.

As a Mitsubishi Electric Diamond Contractor, ICS installs systems backed by an upgraded warranty and built for real efficiency — not just in mild weather, but through cold Northern NJ and NYC winters too.

  • A room addition or finished basement with no ductwork
  • Uneven temperatures because forced air can't reach every room
  • High bills from heating or cooling through old, leaky ducts
  • Wanting independent temperature control, room by room or zone by zone

Good Questions

Ductless Mini-Split FAQs

What is a ductless mini-split system?

A ductless mini-split is a heating and cooling system made up of an outdoor unit connected to one or more indoor units, without any ductwork. Each indoor unit heats or cools the room it's in, so you get targeted comfort in additions, finished basements, or any space where running ducts isn't practical.

Do mini-splits both heat and cool?

Yes. Most Mitsubishi ductless systems are heat pumps, meaning the same unit provides both heating and cooling year-round. With Hyper-Heat technology, they stay efficient even through cold Northern NJ and NYC winters.

How does a mini-split system work?

An outdoor compressor unit connects via refrigerant lines to one or more indoor air-handling units, each controlled independently. There's no ductwork moving air between rooms, which means no duct losses and precise, room-by-room temperature control.

What size mini-split system do I need?

It depends on the square footage, layout, insulation, and how many zones you want to control independently. ICS performs a proper assessment rather than guessing, so your system is sized correctly for real comfort and efficiency — not oversized or undersized. See our HVAC design approach.

How much does a mini-split system cost?

It depends on the number of zones, the system size, and your space's specific requirements. ICS provides a free in-home consultation and a clear, itemized estimate before any work begins, so you know exactly what's involved. Call (866) 749-6331.

Will a mini-split work in cold New Jersey and NYC winters?

Yes. Mitsubishi's Hyper-Heat technology is specifically engineered to maintain efficient heating performance in cold climates, which is exactly what Northern NJ and NYC winters call for. ICS is a Mitsubishi Electric Diamond Contractor, so we install and back these systems with an upgraded warranty.

Do you install ductless systems for commercial properties?

Yes. Alongside residential mini-splits, ICS installs commercial ductless solutions including Iris systems and SVZ air handler units for businesses across Northern NJ and NYC.

Do you provide ductless mini-split installation in NYC and all of Northern NJ?

Yes. ICS installs ductless Mitsubishi HVAC systems in New York City and Bergen, Essex, Hudson, Morris, Passaic, Union, Sussex, and Warren counties in New Jersey, for both homes and businesses.
