FAQ
Yes — car controls, signals, door timing and, where needed, platform or LULA lifts.
Modern drives and LED lighting usually reduce elevator energy use compared with older motor-generator or relay systems.
When parts for the controller are hard to source, callbacks are rising, or inspection orders keep recurring. A condition survey shows whether you're there yet.
Sometimes. A partial modernization (controller and drive, or doors) can be the right first step if the machine and other components are in good condition.
Usually several weeks per car, depending on scope. We phase multi-car buildings so at least one elevator keeps running.
Compliance
San Francisco metro
Buildings in Rohnert Park, Novato, Santa Rosa and San Rafael span several generations of elevator technology — relay controls in older towers, early microprocessor systems from the 1990s and newer machine-room-less units. Our work starts by identifying which generation you have, because that decides what can be repaired and what should be replaced.
We also review existing maintenance contracts so the new equipment is looked after properly once it is installed.
Seasonal swings, rain and humidity make pit drainage and corrosion checks part of routine maintenance.
