My overall rating of 4 stars is based upon the wait time to begin. My appointment was at noon which means the technician should have been there between 11-1. However, service didn't begin until 3:30pm. I realize that unforeseen things can and do happen at previous appointments but a call should have been made by the tech to update the next appointments on the hour of showing up. I shouldn't have had to call the office to find out the status of my appointment. I would still recommend them as the service was very thorough and professional.
