Equipment reliability can be evaluated using failure frequency, work-order history, repair frequency, downtime, warranty claims, replacement rates, and the amount of time equipment operates between service events.

Hotels should evaluate reliability by equipment category and model where possible. Combining every television, PTAC units, refrigerator, or other asset into a single maintenance metric can hide important differences in product performance.

Reliability data becomes particularly valuable when hotels are comparing products for future procurement or determining whether an aging equipment category should enter a replacement cycle.
