Bunn Frozen and Cold Beverage Machine Service

Margarita Guys can service your CDS or Ultra machine as well as any Bunn cold beverage machine, including everything from
periodic maintenance to motor replacements to refrigeration system repairs. We are a Bunn Service Partner and we have
factory-trained Journeyman Technicians on staff.

Call us toll free at 877-99FIESTA (877-993-4378) for help with your machine. Our normal range for service response is 60 miles from
Sacramento, but we often service machines much farther than this area (we've travelled hundreds of miles to service machines).

We maintain a huge inventory of repair parts and we ship the same day via Priority Mail, so you normally get your parts in
no more than 2 days.

Our technicians are also certified to EPA's highest "Universal" level for the handling of regulated refrigerants and are proud
to maintain the highest standards for protecting our environment from ozone-depleting and greenhouse gasses.
