Wiegmann Associates has completed an HVAC renovation and upgrade project at Parkway North High School in St. Louis, MO. The work was part of a $13 million program for improvements at Parkway North High School. The general contractor is ICS Construction Services. The HVAC project included demolition and installation of new energy efficient HVAC equipment, and recommissioning of an existing chiller and boilers. Wiegmann also installed two new chillers and a new rooftop unit with an energy recovery wheel.

Much of the work was completed while school was in session.

Working in tight mechanical rooms and spaces, Wiegmann demolished and recommissioned several existing chiller and boiler plants, modified the existing air duct system and installed new variable air volume (VAV) boxes and sound attenuators in the ductwork.

Wiegmann Associates is a St. Louis-based mechanical contractor serving the commercial, industrial and institutional markets, and a national leader in design/build HVAC projects.
