How long does it take you to get to Richmond from San Ramon?

Roughly 40 minutes, out through the Caldecott on 24 and up through Berkeley, or around on 680 and 4 depending on traffic. We serve Berkeley and Oakland on the same side of the hills, so Richmond calls join an existing route most weeks.

Do you work with Spanish-speaking staff?

We make it work. Quotes and invoices are written and itemized, which keeps everything clear, and photos of the failed parts go with the paperwork so everyone involved sees exactly what was found and what was replaced.

The machine still runs but weaker every month. Should we wait for it to die?

No, and this is judgment from experience: a machine fading gradually is usually losing refrigerant, and the compressor pays the price the longer it runs low. Finding the leak now is a repair. Waiting often turns it into a compressor replacement at several times the cost.

Donper in Richmond

Donper commercial service.

Richmond has one of the East Bay's best street-food economies, and frozen treats are a real part of it. The raspado and juice spots along the 23rd Street corridor, the taquerias running slush machines beside the horchata, and the c-stores working the 80 and 580 interchanges all depend on machines that pour cold product all day. A lot of that equipment is Donper.

These are hardworking businesses and I quote them the way I would want to be quoted: the real number, in writing, before any work. The $75 diagnostic gets waived when you approve the repair, and if the machine is not worth fixing I say so plainly instead of selling a repair that will not hold.

ADRIUM Service Solutions is based in San Ramon. Owner Andrew Kuznetsov is EPA Section 608 Universal certified, CSLB #1136642, and we schedule 7 days a week because your busiest days are the weekend.

Common repairs we do

What we close on the truck.

Bowl freezing weak on heavily sweetened recipes. Raspado and agua fresca recipes often run more sugar than the machine's design assumes, and high-sugar mix freezes at a lower temperature. The machine is fine, the setpoint is wrong for the recipe. I adjust the consistency control for what you actually pour, which fixes the watery product complaint without replacing a single part.
Gearbox worn out from years of daily duty. Machines that have poured daily for five or more years reach the end of the gearbox's life, and the grinding is unmistakable. I quote the gearbox replacement with the real part, not a generic motor forced to fit, because the auger torque spec matters. Done right, the drive is good for another long stretch of service.
Condenser fouling from street-facing installs. Machines positioned in windows and near open doors for visibility pull in street dust constantly. The condenser mats up, afternoon performance drops, and summer becomes a fight. I clean the coil properly and, where the layout allows, adjust the intake orientation so the machine stops eating the sidewalk.
