NesbittAire wrote the book on classroom comfort. John J. Nesbitt pioneered the development of the classroom unit ventilator way back in 1917. Subsequent innovations have made NesbittAire a legend in classroom heating, ventilating, and air conditioning equipment for new and replacement applications.

From coast to coast, school administrators, specifying engineers and building maintenance professionals consider the NesbittAire unit ventilator the most cost effective, energy-efficient system for maintaining the ideal environment in individual classrooms.
