There's one way to know if an elevator system is headed down. Increasing service calls or callbacks and increasing downtime are critical indicators of potential problems.

One way to be proactive with elevator maintenance is to do periodic traffic analyses. Elevator maintenance technicians can attach a system analyzer to the elevator group control panel to evaluate the current traffic patterns of the existing building population as it relates to the original group performance criteria. This will provide an indication of how adequately the system is meeting occupants’ needs.
If wait times exceed 25 to 35 seconds, a modernization may be in order. Or a maintenance audit may determine ways wait times can be reduced without a full modernization.
