I thinking the same thing. Tech support would be hard. Customers are fed up with these heavy handed Major companies....There is no more integrity to the business. I have to also say the customer has some fault too!!! It costs money to service your units. If you pay peanuts you get peanut service! I see that in Europe there is a Tech Support Company that will support Independent Elevator Contractors? I would think these services should be available in the near future for us in the USA at some point?
