The scope includes demolition of existing equipment, supply and installation of two Carrier rooftop units, new gas, condensate, and electrical connections, roof‑curb work, duct‑work repairs, testing‑adjusting‑balancing, commissioning, one‑day on‑site training, and a full set of as‑built and warranty documentation. An optional lump‑sum duct‑cleaning item is also offered.

Budget estimate

$600,000 – $1,200,000

Based on typical costs for two Carrier rooftop units, associated gas/electrical work, a full Johnson Controls BMS, demolition, duct repairs, testing/balancing, training, and warranties, a mid‑size municipal building project of this nature usually falls in the $600 k–$1.2 M range. The low end assumes minimal duct‑modification and a straightforward installation; the high end accounts for complex roof penetrations, extensive BMS programming, and the optional duct‑cleaning scope.
