Since you are based in San Ramon, how fast can you actually get here

Very fast, since this is home base and there is no travel time to add. San Ramon neighbors Danville, Alamo, Dublin and Pleasanton, all of which we cover, so San Ramon and its immediate neighbors are the quickest calls we run.

My large home has hot and cold rooms. Can Lennox zone it

Yes. We set up Lennox multi-zone with dampers and separate thermostats so each part of a big San Ramon home holds its own temperature. I balance the system so one zone calling does not starve another.

Is the $75 diagnostic really waived with the repair

Yes. You pay $75 for the diagnosis. When you approve the repair, that $75 comes off the bill, and the written quote comes first.

Lennox in San Ramon

Lennox heating and cooling in San Ramon.

San Ramon is home for us. ADRIUM is based here, so the newer developments out in Windemere and Gale Ranch and the older neighborhoods around Twin Creeks and San Ramon Village are the homes I know best. It sits inland in the Tri-Valley with hot dry summers and no bay breeze, so cooling loads are heavy and the systems run long. The newer homes carry full Lennox setups, often two-stage or variable with zoning, and they work hard from June into October.

We run HVAC through Bay Area HVAC Service, the ADRIUM division. I am EPA Section 608 Universal certified and we hold CSLB 1136642. The $75 diagnostic is waived when you approve the repair, you get a written quote, and we work 7 days, with no travel time to add since this is our base.

Lennox gives you strong SEER numbers that earn their keep in a San Ramon summer, and the equipment performs. My honest caveat is the parts ecosystem. Lennox keeps its proprietary boards and modules in a dealer-restricted channel, so a Lennox-specific control can take longer and cost more than the Carrier or Trane part. Being based right here I move fast on the labor, but the part lead time is what it is and I tell you up front.

Common repairs we do

What we close on the truck.

XC25 variable condenser inverter board faulting. In the newer San Ramon homes the variable XC25 runs at high capacity through the hot afternoons and the inverter control board faults on heat. I confirm the fault under load and check the board cooling before ordering, since that board is the slower dealer-restricted part.
iComfort zoning damper failing in Windemere builds. The newer zoned homes run iComfort with multiple dampers, and a damper actuator or the zone board fails so one room stops cooling. I trace the specific zone and the actuator rather than condemning the whole control, which keeps the repair cost down.
Furnace flame sensor fouling in dry summers. San Ramon's dry summers pull dust into the furnace and the SureLight flame sensor fouls, so the furnace lights then drops out on a failed flame proof. I clean or replace the sensor and check the burner and the ground before assuming the board is bad.
