How do you route to Moraga from San Ramon?

Up 680 to 24, out through Orinda or over via Lafayette, about 30 minutes. Moraga rounds out our Lamorinda loop with Orinda, Lafayette, and Walnut Creek, so we are nearby on a regular basis.

Can you get us ready before the students return in August?

Yes, and please book it in July. A recommissioning visit covers seals, blades, valves, coil cleaning, and a monitored test batch. It is far cheaper than losing the first week of the semester to a dead machine.

What is included in your written quote?

Parts, labor, and the warranty terms, itemized before any work starts. The $75 diagnostic is credited when you approve the repair, and repairs are covered for one year.

Donper in Moraga

Donper commercial service.

Moraga is quiet until you count the students. Saint Mary's College keeps a steady stream of young customers moving through the Rheem Valley and Moraga Center shopping areas, and the yogurt and boba spots there run their Donper machines on a school-year rhythm: heavy September to May, quiet summers.

That rhythm means August is the month that matters. A machine that limped through spring and sat all summer needs to be right before the students come back, because the first three weeks of the semester are the year's best. We do a lot of late-summer recommissioning in Moraga for exactly this reason.

We are ADRIUM Service Solutions from San Ramon, about 30 minutes away. EPA 608 Universal certified, CSLB #1136642. $75 diagnostic waived with repair, written quotes, available 7 days.

Common repairs we do

What we close on the truck.

Post-summer startup failures. Machines idled for ten weeks come back with dried seals, sticky solenoid valves, and sometimes a compressor that flooded with migrated refrigerant. I recommission properly: seals inspected, valves exercised, crankcase warm before start, then a monitored pull-down. Rushing this step is how August becomes an expensive month.
Solenoid valve stuck on a two-flavor unit. On twin-bowl Donper slush units, a solenoid that sticks closed leaves one flavor warm while the other freezes fine. Students notice immediately and order accordingly, so half your menu dies quietly. The valve swap is quick once diagnosed, and I confirm with pressure readings rather than parts-cannon guessing.
Scraper blade wear from school-year duty. Nine months of daily service takes blades from sharp to useless, and worn blades make the compressor run long to compensate, which shows up on the power bill before it shows in the cup. Blade replacement plus a cylinder inspection each summer resets the machine for the next school year.
