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

San Ramon is about 20 miles from Livermore, straight up I-580. We run calls in Livermore regularly and treat it as a standard service area. Travel time does not add to your invoice.

Is Tempstar a solid fit for Livermore homes, or should I be looking at a different brand for the climate?

Tempstar is built on the same platform as Carrier and Heil. The bones are sound Carrier-engineered hardware at a lower price point. For Livermore specifically, the bigger question is sizing and equipment type. A ducted split system with a properly sized AC or heat pump handles the hot summers well. The communicating variable-speed models in the Tempstar lineup can manage those big temperature swings more efficiently than single-stage equipment. What you give up with the Tempstar badge is the larger dealer network, not the underlying hardware quality.

What does the $75 diagnostic cover, and what kind of warranty comes with the repair?

The $75 gets you a full inspection of the system, fault code retrieval off the control board, component testing, and a written quote for whatever we find. If you approve the repair, the $75 comes off the total. The repair itself carries a 1-year warranty on parts and labor. If we are installing new equipment rather than repairing existing, that work is backed by a 10-year parts warranty and 10-year labor warranty.

Tempstar in Livermore

Tempstar heating and cooling in Livermore.

Livermore sits at the eastern end of the Tri-Valley, and the climate shows it. Summers regularly push past 100F in the afternoon, then drop 30 degrees after dark. That thermal cycling is hard on equipment. Most of the housing stock here is post-war ranch and tract homes from the 1960s through the 1980s, built with central forced-air from the start, so Tempstar gas furnaces and split-system AC condensers are common. The older neighborhoods around downtown and the vineyard-edge streets on the south side have had time to accumulate deferred maintenance, and that is usually where we find the failing igniters and worn contactors.

When a Tempstar unit comes in for diagnosis, we pull the board fault codes first. Tempstar shares the ICP platform with Heil and Comfortmaker, and under that is Carrier-engineered hardware, so the fault logic and the components are the same across all three labels. That matters because we know exactly what to look for: a QuietComfort furnace throwing a lockout code after a few heating cycles is almost always the hot surface igniter or the flame sensor, not something exotic. On the cooling side, a system that trips the high-pressure limit on a 100-degree Livermore afternoon gets a full refrigerant circuit check, not only a capacitor swap. We do not replace parts by guessing.

Bay Area HVAC Service is our HVAC division, operating under CSLB license 1136642 and EPA Section 608 Universal certification. Diagnostic visits are $75, and that fee drops off the invoice if we do the repair. Before any work starts you get a written quote. Installations carry a 10-year parts and 10-year labor warranty. Repair work is backed for a year.

Common repairs we do

What we close on the truck.

Hot Surface Igniter Failure. The most common furnace call we get on Tempstar equipment is a no-heat condition where the inducer runs, the gas valve opens, and then nothing lights. The silicon nitride igniter is a wear item and typically reaches the end of its life somewhere between 5 and 10 seasons of hard cycling. Livermore furnaces work harder in winter than people expect given the mild Bay Area reputation, because the inland valley gets real cold overnight. We verify the igniter resistance is out of spec, confirm the control board is firing the correct voltage at the right time, then replace the igniter and cycle the system through multiple starts before leaving.
Flame Sensor Carbon Fouling. A furnace that lights and then shuts off within a few seconds is usually a contaminated flame sensor rod. The sensor passes a tiny current through the burner flame to prove ignition; carbon buildup on the rod insulates it and the board reads no flame even though the burner is on. We clean the rod, verify microamp draw during operation, and inspect the burner for anything that would accelerate recontamination. On units that have had this happen repeatedly, we also check the gas pressure and heat exchanger condition, because chronic fouling sometimes traces back to an underlying issue.
Condenser Capacitor and Contactor Wear. Livermore AC condensers run long hours through June, July, and August, and the start and run capacitor on a Tempstar outdoor unit typically does not last more than 10 to 12 years under that workload. A weak capacitor shows up as a hard-starting compressor, slow fan spin-up, or a unit that trips on thermal overload during peak afternoon heat. The contactor also takes mechanical wear from frequent cycling. We test both components under load, replace what is out of spec, and check the refrigerant charge and coil cleanliness before closing up, because a low charge or blocked coil will kill a new capacitor faster than normal.
