What is your travel time from San Ramon to Mountain View?

About 45 minutes via 680 and 237, longer at peak commute. Mountain View sits in the middle of our South Bay loop with Sunnyvale, Los Altos, Palo Alto, and Menlo Park, so we cross the bay in this direction often and priority calls fit into most runs.

Our kitchen is tiny. Do you need the machine pulled out before you arrive?

Usually not. Tell us the install situation when booking and we plan the visit around it. If a pull-out is unavoidable we do it ourselves, carefully, and put everything back.

Do you handle both the slush machine and the soft serve unit in one visit?

Yes, and it is the efficient way to do it. One trip charge, both machines diagnosed, one written quote covering everything found.

Donper in Mountain View

Donper commercial service.

Castro Street packs more food service per block than almost anywhere in the South Bay, and the dessert and boba operators there run frozen beverage machines in kitchens with no spare square footage. Working on a Donper wedged into a Castro Street back-of-house is its own skill, and we bring the right gear to do it without dismantling your prep area.

The campus side of Mountain View is a different job: facilities-run cafe spaces with Donper soft serve as a perk, ticket systems, and badge access. We handle vendor requirements without drama and leave documentation that makes sense to a facilities manager, not just to another technician.

ADRIUM Service Solutions runs from San Ramon. Owner Andrew Kuznetsov, EPA Section 608 Universal, CSLB #1136642. Written quotes first, $75 diagnostic waived with repair, 7-day scheduling.

Common repairs we do

What we close on the truck.

Overheating in zero-clearance installs. Castro Street kitchens push machines against walls and under shelving, and a Donper needs its condenser air like you need lungs. Recurring thermal trips in a tight install are an airflow problem wearing a compressor-problem costume. I measure intake and discharge temps, fix what clearance I can, and give you the honest minimum spacing the machine will tolerate.
Torque feedback faults on soft serve units. The consistency control on Donper soft serve reads beater motor load, and when that feedback circuit drifts, product swings between soup and concrete with no settings change. I test the sensor circuit under real load and replace the failed component rather than the whole board when the board is innocent, which it usually is.
Hopper refrigeration failure spoiling mix. The hopper on a soft serve unit keeps mix at safe temperature between servings. When hopper cooling dies, mix spoils quietly while the cylinder still freezes fine, and that is a health inspection problem before it is a mechanical one. I check hopper temps on every visit and repair the hopper circuit with the same care as the main system.
