Parklawn Elementary School


Energy-Efficient Commercial HVAC & Commissioning Services for Schools in the Milwaukee Area

With summer ending and school approaching, Ahern was on a strict schedule to install new boilers in Parklawn Elementary school located in Oconomowoc, Wisconsin. Ahern’s years of experience benefitted to the project by designing, installing, and commissioning the new boiler system. The team overcame the challenge of isolating two 50+-year-old boilers from each other in order for the remaining boiler to operate independently and continue to serve the steam devices. The project was completed on-time, and just in time for classes to begin.
