Barnum Engineered Systems is a family owned and operated business that dates back to the 1950s, originally starting as a refrigeration and air conditioning company. In 1991, cousins Phillip Cavallaro and Vincent Schiavone took over their family’s legacy and built up Barnum to where it is today adding multiple technologies and premium customer service to their product line. Their goal was to continue developing their company with the most recent technological advances while still maintaining the core values that Barnum was founded upon.
