How close is Castro Valley to your San Ramon base?

Very close. We come over 580 through the Dublin grade and it is usually 20 to 25 minutes. With Hayward, San Leandro, and Dublin right next door on our regular routes, Castro Valley is one of the easiest places for us to fit in a same-day call.

You mention Koolaire a lot. Is that the same as Manitowoc?

Koolaire is Manitowoc's value brand, built by the same company with simpler electronics. Our factory seminar covered both lines. Parts logistics are the same, and we stock the common valves and probes that fit both.

What is the warranty on your work?

Repairs are warranted for 1 year, parts and our labor. On new machine installations we back the work with 10-year parts and 10-year labor coverage. Everything is in the written quote before we start.

Manitowoc in Castro Valley

Manitowoc commercial service.

Castro Valley Boulevard carries most of the town's food business, and the kitchens behind it lean on value-line machines. We see a lot of Koolaire heads here, which suits us because our February 2026 factory certification was specifically the Manitowoc Ice and Koolaire Field Service Seminar, run by Jonathan Binley at Pentair Water Solutions. Koolaire uses simpler controls than the Indigo NXT, so diagnosis depends more on the tech knowing the sequence of operation cold.

Off the Boulevard, Castro Valley is ranch homes on big lots, and a growing number of them have ADUs with compact ice makers and undercounter refrigeration for rental units. Those small machines fail differently than commercial heads, mostly water level and float problems, and we service both ends of that range.

We are ADRIUM Service Solutions, Andrew Kuznetsov's company out of San Ramon, EPA 608 Universal, CSLB #1136642. This is one of our closest service areas. $75 diagnostic waived with repair, written quotes, seven days a week.

Common repairs we do

What we close on the truck.

Grease-loaded condenser on Koolaire kitchen units. Koolaire machines in Boulevard restaurant kitchens pull in cooking grease that turns the condenser into a felt blanket. Capacity drops, cycles run long, and eventually the unit trips on pressure. We degrease the coil properly, not just a rinse, and check that the fan blade and motor survived running hot.
Water level probe faults on compact ADU units. Small-footprint machines in ADUs and in-law units use a water level probe or float that scales up fast when nobody maintains it. The machine overfills or dry-runs, and tenants just report that the ice stopped. We descale or replace the sensor, clean the sump, and set the owner up with a realistic maintenance interval.
Harvest safety limit trips. When a Manitowoc hits its harvest safety limit repeatedly, the slab is not coming off the evaporator in time. Causes range from a weak hot gas valve to a scaled evaporator surface to low charge. We work through them in order with gauges on the machine instead of swapping parts on a hunch.
