Aging HVAC and pumps at John Hersey High drive energy inefficiency and risk

District staff and the video narrator highlighted that much of John Hersey High's heating and cooling equipment dates to the late 1960s and has lost efficiency because of hard deposits on cooling coils.

"They basically do all the heating and cooling for 80% of the school. These units have been in operation since the late '60s," a staff member said while describing the built-up coils and the associated loss of efficiency that increases energy use. The staff member explained some components are no longer manufactured and spares are harder to obtain.

The segment notes that the bond's heating-and-cooling category would fund replacements that the annual capital program cannot reach. Staff also highlighted that two pumps do the whole school's heating; while one pump can back up the other, simultaneous failure could cause a loss of heat until repairs are made.
