How often does a home elevator need routine maintenance?
Most residential elevators benefit from a professional service visit one to two times per year, covering lubrication, safety interlock testing, leveling accuracy, and inspection of cables, hydraulic fluid, or the vacuum seal depending on elevator type.
Frequency depends on usage — a household using the elevator multiple times daily wears components faster than one using it occasionally — and on elevator type. Hydraulic systems need fluid and valve checks that traction and vacuum systems don't; vacuum systems need seal and cylinder inspection that hydraulic systems don't. A generic “once a year” answer from a contractor who hasn't asked about your unit type or usage pattern is worth a follow-up question.
