ARTICLE 26 School Rooftop HVAC Unit Replacement Article 26 HVAC Unit Replacement Move to transfer from Free Cash the sum of $75,000 to be expended under the direction of the Facilities Director for the purpose of constructing, reconstructing, or making extraordinary repairs to the Sudbury Public Schools rooftop HVAC units.

This article requests $75,000 for the replacement of rooftop HVAC units at either the Peter Noyes School or the Loring School. The condensing coils are starting to wear out and are leaking. These rooftop units provide the cooling systems for our school buildings and are becoming older and need to be replaced. The existing units are approximately 15 years old and at the end of their useful life. The units have been well maintained, however, repairs and service calls on the aging units have increased. This project would also update the refrigerant from R22 to 410A, which is required by law and is more environmentally responsible. The plan for FY16 is to be prepared for replacement of one school system, the exact unit number will be decided in the summer with replacement scheduled for the fall.
