Do you actually come out to East Palo Alto, or do most Peninsula HVAC companies skip it?

We come out. We keep a technician living on the Peninsula in San Mateo County, and East Palo Alto is inside that coverage the same as Menlo Park or Redwood City. Arrival windows are real, and we're on call every day of the week.

My duplex doesn't have central air. Can you still install or work on a Bosch system here?

It depends on what ductwork, if any, already exists. A lot of East Palo Alto properties were never built with forced air, and an IDS ducted heat pump needs functioning ducts to make sense. On a site visit I check what's actually there before recommending anything, rather than assuming every property fits the same system.

I'm a tenant and my landlord asked me to call. What does the $99 diagnostic cover, and who do you bill?

The $99 covers a fault code pull, electrical and sensor checks, a refrigerant assessment, and a written repair quote. I confirm with whoever's authorizing and paying, owner or tenant, before any repair work starts, and that same $99 comes off the bill if the repair gets approved that visit.

Bosch Home Comfort in East Palo Alto

Bosch Home Comfort in East Palo Alto kitchens.

East Palo Alto has a different housing profile than most of the cities around it. A large share of the housing stock is rental duplexes, small apartment buildings, and older single-family homes built for a working-family city rather than the larger custom lots a few miles west. Central ducted systems exist here, but they're not universal the way they are in some Peninsula neighborhoods, and a fair number of properties were never built with forced air at all. That changes the first question on a Bosch Home Comfort service call: does the ductwork to run an IDS system already exist, or is this a house where a repair on an older split system is the more realistic scope.

Where a Bosch IDS or BOVA system is already installed here, the diagnostic approach is the same as anywhere else. I pull the inverter board's fault history first, because guessing at a symptom wastes a landlord's or a tenant's money either way. Rental properties add a wrinkle: a system that's been run hard with maintenance delayed over who's responsible for the repair often shows up with corrosion on control connections or a coil that's never been cleaned, and I check for that before I call anything a part failure.

Bay Area HVAC Service handles this work as the HVAC side of ADRIUM Service Solutions, an owner-operated company out of San Ramon. We keep a technician living on the Peninsula in San Mateo County, so East Palo Alto is a normal stop, not a special trip. The diagnostic runs $99 and comes off the bill if you book the repair the same visit. You get a written quote before any work starts, and we're on call 7 days a week. We hold CSLB license 1136642 and EPA 608 certification for refrigerant handling. We're an independent shop, not a Bosch factory dealer, and on rental properties I always confirm with the person paying the bill, owner or tenant, before ordering parts.

Common repairs we do

What we close on the truck.

Control Connections Corroded from Deferred Maintenance. On rental properties where HVAC upkeep sat on a back burner, I regularly find corroded low-voltage terminal connections between the IDS indoor and outdoor units. That shows up as intermittent communication faults, a thermostat that goes blank, or a system defaulting into a limp operating mode. I clean and re-terminate the connections and check the fault log to confirm the communication fault has actually cleared rather than just reset temporarily.
Inverter Board Fault from an Unmaintained Outdoor Coil. A dirty outdoor coil raises head pressure, and the IDS board eventually throws a protective fault and shuts the compressor down rather than let it run into an unsafe range. This is common on properties where nobody's cleaned the condenser in years. I clean the coil first and recheck the fault before assuming the board itself failed, because a lot of these calls resolve with coil cleaning and a charge check, not a parts order.
Thermistor Failure Misread as a No-Cool Call. A failed or drifted thermistor on the suction line or outdoor ambient sensor makes the inverter drive modulate incorrectly, and the tenant experience is simply the house not cooling. I check actual sensor resistance against the manufacturer's curve before replacing it, since it's an inexpensive part and an easy fix once it's confirmed as the actual cause.
