How far out is Portola Valley from your San Ramon office for a service call?

It runs 50 to 60 minutes down 680 and over on either 92 or 280. We schedule Portola Valley on the same Peninsula day as Hillsborough, and you get a confirmed written arrival window, not a wide guess.

We are worried about heating and cooling during a PG&E shutoff. Does a heat pump make that better or worse?

A heat pump does not solve a power outage by itself, it still needs electricity to run, but it does simplify the backup conversation because you are running one system instead of a gas furnace plus a separate AC. If you already have or are considering a generator or battery setup, I look at how the transfer equipment is wired to the outdoor unit and flag anything that could cause the rough power transitions I see fail control boards after repeated outages.

What does the $99 diagnostic include and what is the warranty on repairs?

The $99 covers a full diagnostic: fault codes, electrical and refrigerant checks, a look at the outdoor unit's condition, and a written quote for whatever we find. Go ahead with the repair that visit and the $99 is waived. Repairs carry a one year parts and labor warranty, and new installations carry a ten year parts and ten year labor warranty. On rebates, we check what is actually funded at the time of your estimate instead of quoting an old number.

Bosch Home Comfort in Portola Valley

Bosch Home Comfort heating and cooling in Portola Valley.

Portola Valley sits in the oak-and-redwood hills off Alpine Road and Portola Road, a quiet town with large custom homes on wooded acreage, mid-century modern houses in the pockets near Ladera, and ranch properties spreading out toward Skyline. This is a wildfire-aware community, and PG&E public safety power shutoffs happen often enough that homeowners think seriously about backup power before they think about anything else. That context shapes a lot of the Bosch Home Comfort conversations I have here, because a heat pump conversion raises real questions about what happens to heating and cooling during a multi-day outage.

On the mechanical side, when a Bosch IDS or BOVA system faults, I pull codes at the outdoor controller and the air handler board first. These are communicating inverter systems, and the fault log almost always narrows it down, a thermistor reading out of range, an inverter bridge overcurrent trip, a refrigerant pressure anomaly. Properties on the outer roads toward Skyline often run well water and septic systems, which does not touch the HVAC directly, but it does mean I confirm site access and any generator or backup transfer equipment before I start, since several homes here run the whole house, heat pump included, off a transfer switch during outages.

ADRIUM Service Solutions is our Bay Area HVAC division, based in San Ramon. The diagnostic fee is $99 and we waive it if you approve the repair the same day. You get a written quote before anything starts. We carry EPA Section 608 Universal certification and hold CSLB license 1136642, and repairs come with a one year parts and labor warranty. We tell every Portola Valley homeowner plainly that ADRIUM is not a factory-authorized Bosch service center, and the practical effect is that an inverter board ordered outside of warranty can take time to arrive, which we flag in the quote up front.

Common repairs we do

What we close on the truck.

Compressor and Control Faults Following a Public Safety Power Shutoff. A Bosch IDS or BOVA system that switches from utility power to a generator or battery backup during a PSPS event can take a rougher transition than the system is built around, and the outdoor unit sometimes locks out on a control fault right after the switch rather than during normal running. I check the transfer equipment and the power quality at the outdoor unit alongside the usual fault codes, because on these calls the root cause is often the transition itself, not the compressor.
Inverter Board Overcurrent Fault on a Heating Call. An outdoor unit that starts a heating cycle and trips on overcurrent or a DC bus fault within the first thirty seconds is one of the more common Bosch calls I run in this part of the Peninsula. Usual causes are a failing inverter power module, a partly blocked outdoor coil, or leftover refrigerant overcharge from a previous service. I check refrigerant pressure and clean the coil before I condemn the board, since a board swap that misses the real cause fails again.
Reversing Valve Sluggishness in the Oak and Redwood Canopy Shoulder Season. The shoulder season runs long here, cold nights under the oak and redwood canopy followed by afternoons warm enough to call for cooling, and that back and forth puts repeated cycles on the reversing valve solenoid. The complaint is usually a unit blowing cool air for the first few minutes of a heating call. I check discharge and suction pressure through a mode switch to see whether the solenoid or the valve itself is sticking before I quote a fix.
