How far is Hillsborough from your San Ramon base?

It is a Peninsula run. From San Ramon I take 680 to 84 across the Dumbarton, then up the Peninsula past Atherton and toward Palo Alto to Hillsborough. Figure 50 minutes to an hour, so I schedule it ahead.

Can you work without disturbing the finished rooms?

Yes. I diagnose by zone from the Daikin fault codes and repair only the failed head or branch, which keeps the work contained. I give a written quote first.

Do you provide written quotes before any estate work?

Always. I read the codes, find the cause, and hand you a written price before opening anything further. Repairs carry a 1-year warranty.

Daikin in Hillsborough

Daikin heating and cooling in Hillsborough.

Hillsborough is Mid-Peninsula estate territory, full of large period homes on big lots with mature landscaping. The climate is mild and Peninsula-moderated, so the Daikin work here is multi-zone systems balancing comfort across many rooms, often in older homes where ductless and concealed-duct Daikin units were added without tearing up historic finishes.

We are a Daikin authorized servicer, factory trained on the inverter platforms. In a Hillsborough estate the cost of disturbing finished rooms is high, so reading the fault code correctly matters. I isolate the failed branch or head from the code and repair only that. I do not parts-swap.

ADRIUM Service Solutions provides HVAC through Bay Area HVAC Service. The $75 diagnostic is waived with repair, quotes are written, and we hold EPA 608 Universal certification and CSLB license 1136642. Install carries 10-year parts and 10-year labor warranty.

Common repairs we do

What we close on the truck.

Concealed-duct unit airflow fault. Hillsborough estates often hide Daikin concealed-duct units in ceilings and attics. When static pressure rises or a blower weakens, the unit flags a fan fault and a room goes warm. I check the duct path and the blower, then repair the actual restriction or motor.
Ceiling cassette condensate pump failure. Recessed Daikin cassettes in finished ceilings rely on a condensate pump. When it fails the float trips an A3 to avoid a ceiling leak. I test the pump and float and replace the pump before water reaches the plaster.
Branch selector communication dropout. On a large multi-zone Daikin a U4 or UF code means the branch wiring lost communication. In big estates the long runs hide one loose terminal. I meter the bus and repair the exact fault rather than swapping boards.
