We install Carrier, Bryant, York, Ducane, Honeywell and Aprilaire equipment, and we service every major furnace and air conditioning brand regardless of who installed it. Bryant is our most-installed residential line because it offers reliable equipment at a fair price. Carrier covers our premium efficiency work, including 96% AFUE two-stage furnaces and the WeatherMaker commercial rooftop line. York is chosen for durability and excellent Chicago-area parts availability, and Ducane offers value-focused equipment built on Lennox engineering. For controls we install Honeywell thermostats, and Aprilaire supplies our whole-home humidifiers, dehumidifiers and high-efficiency media filtration.
