Rooftop plant replacement study
Challenge. Eleven rooftop units on a 96,000 sq ft outpatient campus were between 17 and 22 years old, and a single-year replacement quote had stalled the capital request twice.
Approach. Full condition assessment with refrigerant circuit testing and runtime logging, then remaining-useful-life scoring to separate genuinely failing units from serviceable ones.
Result. Replacement staged across three fiscal years. First-year capital requirement fell 41% and the plan was approved on its first submission to the board.
