Do you come out to Daly City and Brisbane, or just San Ramon?

Yes to both. We don't promise same-day on every call, but we keep a technician based on the Peninsula in San Mateo County, so Daly City and Brisbane get a faster response than a dispatch driving the whole way from San Ramon.

Do you stock Donper parts for these machines?

I carry common wear items like seals, gaskets, and basic electrical parts on the truck. Compressors, gearboxes, and control boards are usually ordered, and we give you the lead time in the written quote before starting anything.

What does it cost to get a Donper machine looked at?

The $99 on-site diagnosis is credited toward the repair. We put the price in writing before I open the machine, so there is no guessing on the final number.

Donper in Daly City

Donper commercial service.

Daly City sits in the fog belt most of the year, and that damp marine air works its way into machines sitting near a door or a loading dock. We service Donper frozen beverage and soft-serve units for the delis, taquerias, and convenience stores around Serramonte Center, Mission Street, and the Westlake shopping district in 94014 and 94015. We also cover Brisbane just over the hill on 101, so a down machine there gets the same response.

Most Donper failures I see in Daly City trace back to moisture working into places it should not be, on top of the normal wear any commercial machine sees. I diagnose the actual cause before anything gets quoted, and the $99 on-site diagnosis is credited toward the repair.

Refrigerant work on the sealed system is done under CSLB #1136642 and my EPA 608 certification, so a recharge is handled to code, not just topped off and hoped for.

Common repairs we do

What we close on the truck.

Compressor and sealed system repair. Barrel stays soupy or the compressor short cycles and never settles into a steady run. I check charge, head pressure, and the condenser fan before deciding whether the compressor itself needs to come out.
Beater motor and gearbox service. A grinding noise, a stalled auger, or a barrel that will not turn point to a worn gearbox or a failing beater motor. I replace the gear set or motor so it spins under full load again.
Control board and sensor corrosion from moisture. Fog gets into control panels here over months and corrodes the connections, which shows up as false low-mix alarms or a panel that stops responding. I clean and reseat what I can and replace boards or sensors that have already failed.
