Do you actually come out to Danville, or is San Ramon the edge of your area?

Danville is a routine stop for us. Our shop is in San Ramon, which puts us right at the edge of Danville, so drive time is short and there is no trip surcharge. We cover Danville regularly, including the hillside neighborhoods up toward Blackhawk and the older subdivisions closer to downtown.

Tempstar is not a brand I hear about much. Is it a good fit for a Danville home?

Tempstar is an ICP brand built on the same engineering platform Carrier uses for several of its own labels. The hardware, the heat exchanger, the compressor, the control board, is sourced and manufactured the same way. Where Tempstar differs is in the dealer network and brand recognition, not in the quality of the components. For a Danville home that needs a reliable ducted gas furnace or a two-stage heat pump for the hot summers here, Tempstar is a sound choice at a lower price point than the badge-premium brands. The higher-end QuietComfort and communicating variable-speed models give you the efficiency and comfort control that this climate actually rewards.

What does the $75 diagnostic cover and what kind of warranty do I get on the work?

The $75 diagnostic covers a full assessment of the system, fault code retrieval, electrical measurements, refrigerant pressure readings if applicable, and a written quote with the specific repair and the price. If you authorize the repair the same visit, that $75 applies directly to the invoice total. Repairs are covered by a one-year parts and labor warranty. If the job is a full equipment installation rather than a repair, that warranty extends to ten years on both parts and labor.

Tempstar in Danville

Tempstar heating and cooling in Danville.

Danville sits in the Tri-Valley inland from the Bay, and the summers here are real. When the delta breeze stalls out in July and August, temperatures in the valley push into the triple digits and the AC runs for days at a stretch. Most of the housing stock through the flatter parts of town, the ranch-style subdivisions off Sycamore Valley Road and the older tracts near downtown, was built with gas furnaces and ducted AC as standard equipment. Tempstar systems show up regularly in those homes, usually installed by a regional contractor rather than a big-box dealer, which is exactly how the brand tends to move.

When I pull up to a Tempstar unit in Danville I pull the board fault codes first, then verify supply voltage, static pressure, and refrigerant charge before I touch a part. Tempstar runs on the same ICP platform Carrier uses for Heil and Comfortmaker, so the failure patterns are predictable: the hot surface igniter, the flame sensor, the pressure switch on a system with high heating hours. On the cooling side, a condenser that has been running hard through five or six Tri-Valley summers will have capacitor and contactor wear that shows up in the data before it shows up as a no-cool call. I do not guess and swap; I measure, confirm the fault, and quote the fix.

Bay Area HVAC Service runs out of San Ramon, which puts us a short drive from anywhere in Danville. The diagnostic fee is $75, and if you authorize the repair at the visit that charge comes off the total. You get a written quote with the scope and the price before any work starts, nothing surprises you on the invoice. We carry EPA Section 608 Universal certification and operate under CSLB license 1136642. Repair work is backed by a one-year warranty; installed equipment carries a ten-year parts and ten-year labor warranty. If there are utility or manufacturer rebates that apply to your job, we confirm what they actually pay at estimate time.

Common repairs we do

What we close on the truck.

Hot Surface Igniter Failure on Tempstar Gas Furnaces. The hot surface igniter on ICP-platform furnaces is a known wear item, and systems with high heating hours in Danville's cold winters burn through them on a predictable schedule. The symptom is a call for heat that goes nowhere: inducer spins up, igniter glows, but no flame lights and the board locks out after two or three tries. I measure igniter resistance cold, verify control board output voltage, and swap in the correct silicon nitride element. The old style silicon carbide igniters are brittle; I handle them without touching the element surface to avoid contamination that cuts the service life.
Flame Sensor Fouling Causing Short-Cycle Lockout. A dirty flame sensor is probably the single most common Tempstar furnace call I run in this area. The burners light normally and then the furnace shuts down within a few seconds, which the board logs as a flame-sensing fault. Combustion byproducts coat the sensor rod over time and raise its electrical resistance above the threshold the board uses to confirm a stable flame. The fix is to pull the sensor, clean the rod with fine steel wool, verify microamp signal back on the board, and check the flue path for anything that could accelerate fouling again, blocked secondary heat exchanger surfaces being the usual culprit.
Condenser Capacitor and Contactor Wear After Heavy Cooling Seasons. Tri-Valley summers are hard on outdoor equipment. After several seasons of sustained operation, the run capacitor on the compressor and condenser fan motor loses capacitance and the contactor contacts pit from repeated high-amperage switching. The system may start sluggishly, pull higher than rated amperage, or fail to start the compressor at all while the fan still runs. I measure capacitance directly and check contactor contact condition before condemning either component. Both are straightforward replacements, but I also check refrigerant charge and superheat while the system is open, because a low-charge condition on an already-stressed compressor accelerates wear and turns a capacitor job into a bigger one later.
