How close is Dublin to your San Ramon base?

Very close. From San Ramon it is a short run up 680, with Pleasanton, San Ramon, and Livermore all right there. Most Dublin calls are 10 to 15 minutes.

My home is fairly new. Why is the Daikin already failing?

Usually it is a charge issue, a control board, or a slow leak from install, not the whole system. I read the codes and find the real cause, then give you a written quote. The repair carries a 1-year warranty.

Do you service the small mini-split in my ADU too?

Yes. We service Daikin ductless heads in ADUs and additions across Dublin. I diagnose the head and the outdoor unit and write you a price.

Daikin in Dublin

Daikin heating and cooling in Dublin.

Dublin grew fast on the east side, so a large share of the housing is newer 2000s and 2010s subdivision construction, much of it already running modern Daikin or similar inverter heat pumps. The climate is hot inland Tri-Valley, so the systems carry a real cooling load through summer. I also see Daikin mini-splits added to ADUs and bonus rooms in these newer homes.

We are a Daikin authorized servicer, factory trained. On Dublin systems the controls are current Daikin inverter platforms, so the fault codes are precise and worth reading carefully. I pull the code, isolate the cause, and repair it. I do not parts-swap. On no-cool summer calls I check charge and coil condition first.

ADRIUM Service Solutions runs HVAC through Bay Area HVAC Service. We are right next door in San Ramon. The $75 diagnostic is waived with repair, quotes are written, and we are EPA 608 Universal certified, CSLB 1136642.

Common repairs we do

What we close on the truck.

Inverter board fault on a newer system. Even newer Dublin Daikin condensers can throw an inverter PCB fault like an L5 or L4 from a power surge or a heat issue. I test the drive, the compressor, and the cooling path so I replace the board only when it is actually the failed part.
Expansion valve or charge fault after a leak. A young system that suddenly cannot cool often has a slow factory or fitting leak and flags a charge or pressure fault. I find the leak, repair the joint, evacuate, and recharge to weight instead of just topping it off.
ADU mini-split drain trip. Daikin mini-splits added to Dublin ADUs often have a quick drain run that clogs and trips the float, showing an A5. I clear and re-slope the condensate line so the unit stops shutting itself off.
