They are absolutely the worst elevator co in Chicago. I have a brand new elevator at the building I built 4 stories 1 elevator $62.5 K which hasn't worked for more then 45 days in a row.My first service cal went rather poorly. I called on a fri nite on a long holiday weekend & had to approve the overtime alyhough nobody of the 3 I spoke could tell me what that would cost or even ballpark it. The work was done It took about an hour. A week later I got a bill for $1600. which was for the o.t. rate of $450 per hour. for tha actual work plus travel time. I then bought a service contract for $200 per month & about a month later it broke down again. I call around 3 on a mon. The tech gets there just past 5 It gets fixed in about an hour & again I get a bill for $1600.because he got there after 5. I didnt authorize the O.T. but got billed again. Im now disputing it & looking for a new company to service my 16 month elevator which breaks down every 45 days.Id look elsewhere for a elev company
