What's your travel time to Cupertino from San Ramon?

Roughly 50 minutes by 680 and 280 outside of rush hour. I bundle Cupertino with Sunnyvale, Mountain View, Los Altos, and San Jose calls into South Bay route days, usually two or three times a week. Book ahead and you get a firm window rather than a maybe.

Our shop cannot lose the machine during weekend traffic. Can you fix it on a weekday morning?

That is exactly how we schedule dessert shops. Weekday mornings before opening are the standard slot, and since most repairs finish in one visit with van stock, you are usually pouring again the same day.

Do you handle the refrigerant side too, or just mechanical parts?

Both. I hold EPA Section 608 Universal certification, so leaks in the cooling drum circuit, recharges, and compressor replacements are all in scope and done legally with documented refrigerant handling.

Bunn in Cupertino

Bunn commercial service.

Cupertino's food scene leans hard into frozen and blended drinks. The boba and dessert shops around Main Street Cupertino and along Stevens Creek run granita and slush programs year-round, and several corporate break rooms in the area keep Bunn dispensers as an amenity. Both environments push machines hard in their own way.

Shop machines here fail from volume, campus machines fail from neglect between facility contracts. I service the Ultra-2, the newer Ultra NX with its touchscreen control, and JDF juice units, and I carry the wear parts that cover most of what these platforms break.

The company is ADRIUM Service Solutions out of San Ramon, owner Andrew Kuznetsov, EPA Section 608 Universal certified, CSLB #1136642. Written quotes before work, $75 diagnostic waived with repair, one-year repair warranty, available 7 days.

Common repairs we do

What we close on the truck.

Ultra NX touchscreen and control faults. The NX moved everything to a touchscreen, and when that interface locks up or loses touch response the whole machine is unusable even though the refrigeration is fine. I distinguish firmware lockups from failed display assemblies before quoting, because one is a reset procedure and the other is a part. Guessing wrong on this one wastes your money.
Over-freezing product in high-volume dessert shops. Shops running low-sugar or dairy-free mixes hit a hard-freeze condition where the auger struggles and drink texture turns icy. The fix is part calibration, part recipe. I set the freeze control to the actual product's behavior, verify torque draw, and leave the staff a written brix range for the mixes they pour.
Auger seal leaks under continuous duty. A machine spinning ten hours a day wears its rear auger seal on a schedule you can almost set a calendar by. Early signs are syrup residue in the drip tray behind the hopper and a sweet fermented smell. Replacing the seal and wear ring at first leak protects the drive motor from sticky buildup that kills it later.
