Our systems are designed to deliver years of trouble-free service, but, just like your car, furnace, or air conditioning system, a residential or commercial elevator requires regularly-scheduled maintenance. Liftavator recommends a bi-annual service for all of our products, which consists of fine adjustments and lubrication. We also check operational function to ensure all buttons work, that the alarm bell sounds when the alarm is pulled, and that all doors and gates are in proper working order. The process usually takes about an hour.
