Construction manager outlines HVAC options and warranty differences for district projects

Construction manager Cliff Holden presented HVAC options discussed at workshop, contrasting an option that pairs Aon RTUs with Aon controls and JACE against an option that uses Lennox RTUs and deck controls. Mr. Holden and staff highlighted warranty differences: with the Aon option the district would receive 10 years of parts and labor warranty and a 15- to 25-year heat-exchanger warranty depending on materials; the Lennox option included 10 years of parts and compressor warranty and a 15-year steel heat exchanger warranty.
