As Buildings Need More Specialized Requirements Without Extra Budget To Spare, The Demand For Flexible Semi-Custom Equipment Becomes Imperative

There are Rooftop Units, Semi-Custom Rooftop Units and Custom Rooftops. As Indoor Air Quality, Energy Efficiency, and Control requirements (to name a few) become more of a driving force in our business, tough decisions need to be made. Do you design/install off the shelf units and field install controls, bolt on energy recovery units and even modify the HVAC unit for capacity control? Do you start with a blank sheet of paper and deal with the high cost, complication and extended fabrication time of a custom unit?

Over the last 20 years the industry has seen the rise of premium semi-custom Rooftop packaged units. It started with 1 brand, who used the mass market appeal of fixed cabinets and mixing/matching of fans, compressors and options to make a matrix of over 100,00o combinations of a unit. This method to market proved positive and over the past few years other brands hit the market with the “me-too” approach.
