Do you cover San Carlos regularly or only when someone happens to be in the area?

San Carlos is part of our standard Peninsula routing with Belmont and Redwood City. Our technician lives in San Mateo County, so Laurel Street is a normal stop for us, not a special trip.

Our machine died during a Friday rush. How fast can you get here?

I won't promise same-day for every call, but being based on the Peninsula means we start closer than a truck coming from San Ramon. We move these up in the schedule when we can.

What's the cost to get someone out?

$99 for the diagnostic, credited toward the repair. You get a written quote before we start.

Donper in San Carlos

Donper commercial service.

Laurel Street carries most of San Carlos's frozen drink business. Restaurants and boba shops along that strip run Donper slush and soft-serve units through lunch and the after-school crowd, and a barrel running warm mid-shift means dumped mix and customers walking past the counter.

San Carlos sits inside our regular Peninsula route alongside Belmont and Redwood City, and our technician living in San Mateo County usually takes these calls directly rather than a truck coming over from San Ramon.

Refrigerant and compressor work is done under CSLB #1136642, and I carry EPA 608 certification for that part of the job. Diagnostic is $99, credited toward the repair, and you get a written quote before anything starts. We work 7 days a week.

Common repairs we do

What we close on the truck.

Compressor and sealed-system repair. A barrel that will not pull down to temperature, or a compressor cycling on and off too fast, points to a sealed system issue. I check refrigerant charge and compressor draw under license before deciding what gets replaced.
Mix sensor and control board faults. False low-mix alarms or a panel that will not respond usually trace back to a bad sensor or a failed control board. I test both before swapping the board on a guess.
Beater motor and gear wear. Laurel Street shops that run the barrel through steady lunch and after-school traffic wear out the beater motor and drive gear faster than a low-volume account. I replace the worn part so the barrel spins and freezes properly again.
