37 Years of Trusted Service | Long Island's First Lennox Premier Dealer

About Central Air Systems in Medford, NY

For 37 years, Central Air Systems has been the name Long Island homeowners and businesses trust for reliable heating, cooling, and indoor air quality solutions. From our headquarters at 22A Scouting Blvd, Suite 2, in Medford, NY, we serve communities across Suffolk County and beyond with the kind of honest, skilled work that keeps families comfortable year-round.

We got into this business because we believe every home deserves dependable comfort without the runaround. That commitment has earned us recognition as Long Island's first Lennox Premier Dealer, along with the Lennox Centurion Award and Partner of the Year honors. But what matters most to us is the trust our neighbors place in our team every single day.

Our Story

Our Story

Central Air Systems was founded with a simple idea: deliver exceptional HVAC service to Long Island families and stand behind every job. Over nearly four decades, that idea has grown into a full-service heating and cooling company equipped to handle everything from central air conditioning installation to geothermal system design and indoor air quality improvements.

Our team, led by Greg Signorile, has built Central Air Systems into one of the most respected HVAC contractors on Long Island. We have never lost sight of the values that got us here: show up on time, do the job right, explain everything clearly, and treat every home like our own.

What started as a local operation has expanded to serve 15 communities across Long Island, from Southampton and Sag Harbor on the East End to Baldwin and Amityville farther west. Our Medford location keeps us centrally positioned to reach customers quickly, whether it is a scheduled maintenance visit or an urgent repair call on the hottest day of summer.
