  • United Service is an outstanding family owned company, we here at Finz Seafood and Grill and Sea Level Oyster Bar have been using them for 15 plus years. Ron, Nic and Alexi and their team have been great to work with, to calling in issues and getting right out to fix the problems and finding parts quickly.

  • We called United Service Company when our ice machine stopped working on a Friday morning.  Our hall was booked for the weekend and buying ice was not an option.  The technician, Nate, was there within a couple of hours and had us making ice again and FAST.  United Service Co was fast, professional, and courteous.  We will DEFINITELY use them again in the future!

  • This has been the second large walk-in purchase from United. Both purchases were installed on time and on schedule. United also services our coolers and responds quickly to last minute service calls. I truly enjoy the relationship with United Service.
