Heating Services › Furnace Repair
Heating season in our service area runs from roughly November through March, with the heaviest demand during Tule fog cold spells in the Central Valley and damp marine cold along the Bay. Most furnace service calls come from one of a handful of root causes: a failing thermocouple or flame sensor, a worn ignitor, a stuck draft inducer, a failed blower motor, a clogged condensate line on a high-efficiency unit, or a thermostat that has lost calibration. Stockton, Tracy and Manteca homes built in the 1970s through 1990s often have original or first-replacement furnaces that are now reaching the end of their service life. Common warning signs include uneven heating, frequent cycling, unusual noises, yellow pilot flame, rising bills, or a system that runs constantly without warming the house. Caught early, most repairs are inexpensive; ignored, they become no-heat calls during the coldest week of the year.
If repair does not make economic sense for an aging unit, we explain why and provide a written estimate for furnace replacement — or for a heat pump conversion that captures California rebates.
Our furnace repair process is fast, transparent and safe-first.
AC Services Elite is a Carrier Authorized Dealer, so the equipment we install is genuine Carrier — engineered for reliability and efficiency and backed by Carrier's full manufacturer warranty. Our technicians are factory-trained on Carrier systems, which means correct sizing, correct installation, and warranty protection you cannot get from a non-authorized installer.
Heating season looks different across our six-county service area. Tule fog in Stockton, Manteca and Lodi creates extended cold spells where temperatures hover in the 30s and 40s for weeks at a time, and any furnace weakness gets exposed quickly. Tracy sits at the western edge of the Valley and adds Altamont wind to that picture, which increases envelope heat loss in older homes. Bay Area cities — Oakland, Berkeley, Daly City — see milder winters but year-round heating demand, especially in older craftsman housing without modern insulation. The Tri-Valley and East Contra Costa cities of Walnut Creek, Antioch and Brentwood see real cold snaps each winter. Many 1970s through 1990s furnaces still in service across these areas are at or past their typical 15-to-20-year lifespan. We repair what should be repaired and recommend replacement honestly when the math no longer works.

Book Free EstimateCommon signs include uneven heating across rooms, a yellow or flickering pilot light instead of blue, short cycling on and off, banging or grinding noises at start-up, a burning or musty smell, rising energy bills with no change in usage, and a furnace that runs constantly without warming the house. In Stockton and Manteca homes with older systems, Tule fog season often surfaces issues that have been building since the last heating season. If you notice any of these, call before the next cold snap; small repairs caught early prevent a no-heat emergency.
Yes. A no-heat call in January on a Stockton fog night is not something that waits for business hours, so neither do we. Call (209) 268-2659 any time and a real dispatcher will route a licensed technician to your home. Emergency dispatch covers all six counties we serve: San Joaquin, Alameda, Contra Costa, Santa Clara, San Mateo and Stanislaus.
Cost depends on the failed component and the age of the system. Many residential furnace repairs — thermocouple, ignitor, flame sensor, draft inducer — are straightforward. Heat exchanger and blower motor failures are more involved. Every visit begins with a flat-rate diagnostic, and you receive a written, upfront estimate before any work begins. If replacement is the better path, we credit the diagnostic toward installation.
It depends on the noise. A high-pitched squeal often points to a failing blower motor and is not immediately dangerous. A loud bang at start-up can mean a delayed gas ignition, which is a safety concern and warrants shutting the system off and calling for service. Any smell of gas, soot near the registers, or a yellow flame in a gas furnace is a safety issue — turn the unit off, ventilate the home, and call us right away.
Yes. Our technicians are trained on both gas and electric residential furnaces. Gas furnace repairs focus on ignition systems, flame sensors, gas valves and heat exchangers. Electric furnace repairs focus on heating elements, sequencers, relays and blower assemblies. We carry common parts on the truck and complete most repairs on the first visit.
If your furnace is a Carrier system within the manufacturer warranty period and the failure is a covered component, Carrier's warranty covers the part. As a Carrier Authorized Dealer we can process warranty claims directly. Labor is typically not covered by the manufacturer beyond the first year, but our written estimate makes the breakdown clear before any work begins.
