Commercial Rooftops

All of our commercial rooftop units and systems, from 1½ tons through 162 tons, are designed to address today’s comfort demands, superior indoor air quality, straightforward installation and minimized energy consumption. Dedicated digital controls enable the use of building management systems to allow for efficient operation and system monitoring to ensure performance to design.


A unitary system combines heating, cooling, and fan sections all in one or a few assemblies for simplified application and installation and are used in most classes of buildings, from schools to offices to retail, particularly where low initial cost and simplified installation are important. Because you should expect more out of your building systems than just hot and cold air, our commercial unitary system features integrated controls engineered to create the best possible comfort environment for your investment.
