Ductless Mini-Split Installation in Long Island

Efficient Heating & Cooling Without Ductwork

Ductless mini-splits deliver powerful cooling — and heating — without the need for traditional ductwork. These systems use a small outdoor unit and sleek indoor air handlers to condition individual rooms or zones with precision. Whether you live in an older Long Island home with no ducts or you need better comfort in spaces like sunrooms, attics, and additions, ductless offers an efficient, modern solution. Homeowners across East Northport, Huntington, Smithtown, and Commack trust us for clean, seamless installs that blend into the home’s design.

What’s Included in Our Ductless Installations

Perfect for Homes With No Ductwork

Older Long Island homes often rely on window AC units or baseboard heat. Ductless mini-splits provide efficient comfort without altering your home’s structure.

Ideal for Additions & Hard-to-Cool Rooms

Sunrooms, converted attics, garages, and home offices are perfect candidates for ductless systems. Each zone gets custom temperature control.

Heating & Cooling in One System

Most ductless systems are heat pumps, offering reliable warmth in winter and cool air in summer — even in below-freezing temperatures.

Multi-Zone Flexibility

Choose a single-zone system for one room or a multi-zone setup to condition several areas independently. Every indoor unit is controlled individually for true comfort.

What to Expect From Our Ductless Installation Team

We begin by assessing your home’s layout, insulation, and comfort goals to recommend the ideal system type and size for each zone. As certified installers for brands like Fujitsu, Mitsubishi, and Bosch, we know how to place indoor units for optimal airflow and minimal visual impact. Our technicians complete clean wall penetrations, conceal line sets wherever possible, and ensure a polished, seamless result. After installation, we test every unit and show you how to control your new system with remotes or smartphone apps.
