Mullrenan Middle School

Mullrenan Middle School project

Coastal Mechanical was awarded the 2021 ABC Excellence in Construction Eagle Award.

This project included a complete mechanical equipment overhaul consisting of removing 2 original chillers and installing 2 new 225 ton chiller units.  All four units were removed and replaced on the same day.  On a 63 day schedule, this challenging job was executed to perfection with removing and reinstalling 150 pieces of equipment, associated piping, and duct work. This was all done with zero accidents and completed in plenty of time for the new school year.
