Our licensed technicians install, repair, and maintain the full range of heating and cooling equipment, including furnaces, heat pumps, ductless mini-splits, and geothermal systems. Whether you’re replacing an aging furnace or adding a ductless zone to a room addition, we can spec and install the right solution.
Indoor air quality is part of what we do, too. We install whole-home humidifiers, air purifiers, and ventilation systems that work alongside your heating and cooling equipment to help keep the air in your home or building clean and comfortable year-round.
Our in-house sheet metal fabrication shop is one of the ways we stand apart. We fabricate, repair, and seal ductwork on-site, and we can modify existing duct systems to address airflow problems or accommodate a new layout. One call to Connecticut Air Systems covers the equipment and the duct system it depends on.

Trusted Brands, Warranty-Backed Installation
We install and service equipment from Trane, Carrier, Thermopride, and other major manufacturers. These are systems built for durability, and we back every installation with a full warranty on our workmanship. Choosing a brand you recognize matters, and knowing the installation itself is covered matters just as much.

Connecticut Air Systems has earned its standing as one of the leading suppliers of heating, air conditioning, and air treatment systems in the area by treating professional service and customer satisfaction as the baseline, not a selling point.
