Do you actually come out to Menlo Park, or is that too far from San Ramon?

We cover the Peninsula regularly and Menlo Park is a standard service area for us. Drive time from San Ramon runs about forty-five minutes to an hour depending on traffic, so we schedule Peninsula calls accordingly and do not tack on a distance surcharge.

My Menlo Park home has original 1950s ducts. Is a Tempstar furnace the right fit, or should I be looking at something different?

It depends on the duct condition. Mid-century ductwork in this area is often undersized for a modern variable-speed unit, which can make the communicating Tempstar models less effective than they should be. We size the equipment to what the duct system can actually move. If the ducts are beyond saving, a ductless mini-split is worth talking through. We give you an honest assessment at the estimate stage, not after the equipment is already ordered.

What does the $75 diagnostic actually include, and what warranty covers the repair?

The $75 covers a full diagnostic: we read the fault history, run the equipment through a call cycle, test electrical components with instruments, and check refrigerant charge or combustion performance depending on the system type. You get a written quote before any repair begins. If you approve the work, the $75 comes off the invoice. Completed repairs carry a one-year parts and labor warranty.

Tempstar in Menlo Park

Tempstar heating and cooling in Menlo Park.

Menlo Park sits close enough to the bay that outdoor units on the west side of town see real salt-air exposure, which chews through contactors and coil fins faster than the inland valleys. The housing mix runs wide: older Craftsman and pre-war homes around the Willows neighborhood often have no ductwork at all, while the mid-century ranch tracts near the Bohannon area were built with central forced-air systems and still rely on ducted Tempstar furnaces and AC condensers. Summers here are milder than the Tri-Valley but warm enough that a heat pump or AC unit that quits in July is still a problem, and the heating season runs longer and damper than people expect.

Tempstar runs on the same engineering platform as Carrier and Heil, so we already know the board layouts, fault codes, and known weak points before we walk in the door. When something stops working we read the control board faults first, check the pressure switch and draft inducer, test the flame sensor with a microamp meter, and confirm actual refrigerant charge with gauges rather than swapping parts until something sticks. On the Peninsula the combination of coastal humidity and occasionally salty air means we pay extra attention to contactor pitting and capacitor condition on outdoor units, because those components degrade faster here than in a dry inland climate.

Bay Area HVAC Service is our HVAC division, and we drive the Peninsula regularly. Diagnostic is $75, and that fee comes off the invoice if you move forward with the repair. Nothing gets touched until you have a written quote in hand. We carry EPA Section 608 Universal certification and hold CSLB license 1136642. Repair work is backed by a one-year warranty; new installs carry ten years on parts and ten years on labor.

Common repairs we do

What we close on the truck.

Hot Surface Igniter Failure. The silicon nitride igniters in Tempstar gas furnaces are fragile and have a finite cycle life. The furnace calls for heat, the inducer runs, the igniter glows, and then there is no flame because the igniter cracked at the element or its connection point. We confirm the fault code, verify 120V is reaching the igniter, and check the igniter's resistance before condemning it. Replacement takes about forty minutes and is a straightforward repair on most Tempstar furnace models.
Flame Sensor Cutting Out After Ignition. This one shows up as a furnace that lights, runs for a few seconds, then shuts down on lockout. The flame sensor rod builds up an oxide coating over time and can no longer pass enough microamps to satisfy the control board. In Menlo Park's damp winters this happens a little faster than in drier climates. We clean or replace the sensor, verify the microamp reading is in spec, and check for any flue or combustion air issues that could be contributing to the contamination.
Condenser Capacitor and Contactor Wear. On Tempstar AC and heat pump outdoor units within a few miles of the bay, the run capacitor loses capacitance and the contactor pits from the combination of load cycling and salt-air corrosion. The symptoms are a unit that hums but does not start, or one that starts slow and trips the breaker under load. We test capacitance with a meter, check contactor contact surfaces, and replace whichever components are out of spec. We carry common Tempstar-compatible capacitors and contactors on the truck so most of these get resolved in one visit.
