Researching residential home elevators can have your head spinning. There are so many questions to answer. Made in USA? Does it involve a leaking hydraulic fluid shaft with a pit drain in my basement floor? Is it a pressurized air vacuum sealed shaft? Who is responsible for future service? Can I get trapped inside when power goes out? How big are they? How loud are they? How long is the warranty? What is the weight capacity? Is it safe? And…Shafted or Shaftless?
