Sam and his crew capably cared for moving our A/C unit when our home was re-roofed, and then reinstalling it. As the re-roofing schedule changed multiple times because of weather and other issues, Sam demonstrated great flexibility in setting and resetting dates for Pro-Tech's work, and then for moving rapidly to reinstall the unit just as soon as roof conditions permitted. I would be astonished if you'll find anyone easier to work with -- and he and his crew do careful, quality work. I'll definitely call them in the future.
