Can you handle a biotech campus cafeteria account with multiple machines?

Yes. Our Peninsula technician is based in San Mateo County, so South San Francisco is a short drive rather than a trip across the bay from San Ramon. We don't promise same-day for every call, but a local base means faster turnarounds on repeat accounts.

Do you cover Brisbane too?

We do. Brisbane sits right next to South San Francisco and gets the same coverage from our Peninsula technician.

How do you handle parts for a machine that goes down mid-shift?

I keep common wear parts like belts, seals, and sensors on the truck. Compressors and control boards usually need to be ordered, and we tell you the lead time in the written quote so you can plan around it.

Donper in South San Francisco

Donper commercial service.

South San Francisco runs two different worlds side by side: biotech campuses off East Grand Avenue with cafeterias feeding hundreds of people a day, and the industrial park kitchens and delis along Grand Avenue and Utah Avenue. We cover 94080 and the Terrabay area, and we handle Brisbane right next door as well.

A machine pushing that many servings a day fails differently than one in a slow neighborhood cafe. I look at what actually broke before quoting anything, and the $99 diagnostic is credited toward the repair.

Gas and refrigerant work stays under CSLB #1136642 and my EPA 608 card, so a recharge on a high-volume cafeteria unit is done correctly the first time instead of something I have to come back for.

Common repairs we do

What we close on the truck.

Compressor wear from heavy daily cycling. A machine running hundreds of servings a day short cycles the compressor harder than a low-volume shop ever would. I check the start components and head pressure before deciding if the compressor needs to come out.
Condenser coil fouling in busy kitchens. Grease and dust from a busy cafeteria or industrial kitchen build up on the condenser coil and choke off airflow, so the unit runs warm even with a correct charge. I pull and clean the coil and check the fan motor while it is open.
Beater motor and gearbox replacement. Constant use wears the gear set and motor bearings down faster in a high-volume kitchen than in a corner cafe. When the barrel stalls or grinds under load, I replace the worn parts instead of patching them.
