Hotels should maintain a limited inventory of critical replacement equipment based on property size, lead times, and how essential each item is to room availability.

PTAC units are often prioritized because a failure can immediately take a room out of service. TVs and appliances may also require spares to maintain consistency and avoid mismatched equipment.

Balancing inventory costs with the risk of downtime is key. Having the right spares available helps hotels respond quickly to failures without disrupting operations.
