Cool marine air often reaches Cotati by way of the Petaluma Gap, and in winter it settles over the flat valley floor as damp fog that holds the cold well into the morning. Most homes in town were built between the 1950s and 1970s, so a lot of them are still leaning on heating equipment that has been running for decades. When that equipment falters, furnace repair in Cotati, CA from KC Home Services Plumbing, Heating & AC Repair gets the heat back on, and we have been doing it across Sonoma County for more than 40 years.
In a town where cold, foggy mornings are the norm all winter, you tend to notice a struggling furnace first thing. Here is what Cotati homeowners and landlords usually spot first.
If you are seeing more than one of these, call before the next cold snap rather than after.
Many Cotati homes from the post-war building boom sit on raised foundations with a crawl space, and some still use the original wall or floor furnaces that were popular back then. Those older units tend to fail in predictable ways, with worn thermocouples, clogged burners, and cracked heat exchangers at the top of the list. Ducted systems added later often run through crawl spaces where winter dampness gets into the insulation and loosens duct joints.
Cotati also has plenty of rentals near Sonoma State, and a furnace that goes years without a filter change or tune up fails sooner than one that gets regular attention. Winter rain and a high water table across the Santa Rosa Plain keep the ground wet for months, and that moisture rusts burner parts and flue connections faster than most homeowners expect.
Our furnace repair services in Cotati, CA start with a full safety check of the burner, heat exchanger, flue, and gas connections, then move into the repair itself, whether that is an igniter, a blower motor, or a control board. We work on the older wall and floor furnaces found in 1950s homes as well as newer forced air systems.
Before any work begins, we explain what we found, what it will take to fix it, and whether repair or replacement makes more sense for your home. You get a straight answer, not a sales pitch.
Bruce called on a foggy January morning when the wall furnace in his 1950s bungalow near the plaza clicked over and over but never lit. Our technician found a worn thermocouple that could no longer hold the pilot flame, along with a layer of lint across the burner from years without a cleaning. After replacing the thermocouple and cleaning the burner, the furnace lit on the first try and the house was warm before lunch. Bruce said he had been sleeping in a jacket for three nights because he figured the whole furnace was finished.
Cotati is small enough that people know who shows up, and we plan to keep earning that trust. Here is what you can count on from us.
