A furnace repair in Tehama County starts at the burner and ignition system, because those are the parts that cycle every time the heat comes on. Homes in Tehama County, CA run heat about eight months a year, from October through May. That kind of sustained cycling wears the igniter and heat exchanger at a pace that shorter seasons do not produce, and a contractor who skips straight to the control board without checking combustion components first is working in the wrong order. Cracks in the heat exchanger and a weakened igniter are what this county's load produces.
Furnace repair in older housing stock turns on one question a contractor cannot answer until the unit is open: whether the parts that system requires are still being made. Half the homes in Tehama County, California were built in 1981 or earlier (2020-2024 ACS 5-year). A house that age was built around equipment whose replacement parts have had time to go obsolete, get redesigned, or simply leave the market. That changes the repair. A contractor who finds a cracked heat exchanger or a failed inducer motor in a system like this has to price the job against what the supply chain actually has, not against a catalog that was current when the house was new.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits inside the furnace cabinet and is where a contractor looks when a home is not getting warm or when there is an unusual smell. The burner assembly, which sits just below it, is another early suspect when the furnace fails to ignite or cycles off before the house reaches temperature.
The blower motor and its wheel sit in the lower section of the cabinet and push conditioned air out through the supply ducts. The control board and the inducer motor, also housed inside the cabinet, govern when each part fires and in what order, so a fault in either one can mimic problems that look like they belong to something else.
The drawing shows a typical furnace layout, and a licensed contractor will determine which parts apply to your specific system and what each one needs.
