Residential Furnace Repair Tailored to SF Microclimates
San Francisco is well known for its unique microclimates, and your heating system is more aware of them than you may think. Living in the Sunset or Richmond areas, your furnace is exposed to environmental stress factors that are never experienced in inland areas.
The first cause of untimely equipment breakdown is the heavy, salty atmosphere that is caused by the Pacific Ocean.
Over time, salty coastal moisture can seep into your furnace cabinet and internal assemblies, speeding up corrosion on heat exchangers, burners, and sensitive electrical components. That is why our residential furnace repair process is built specifically for San Francisco’s coastal conditions.
We go beyond fixing the immediate issue by inspecting oxidation, salt-air rust, and early wear patterns common in neighborhoods near the ocean. This detailed check helps extend system lifespan, improve safety, and reduce the risk of surprise breakdowns during the chilliest weeks of the year.

The microscopic salt particles are transported by the coastal fog in San Francisco which generates electrochemical corrosion. This results in pin hole leakages in the heat exchangers and burner oxidation. We propose an annual inspection of corrosion and the use of protective coating of internal components to avoid early system breakdown in high-humidity neighborhoods.
Common repairs like cleaning flame sensor or changing ignitor normally cost between 150 to 400 dollars. Mid-range repairs, e.g. replacement of the blower motor or a gas valve, cost’s between 450-950 dollars. Big jobs such as a broken heat exchanger may cost more than 1500 dollars at this point, we offer a Repair vs. Replace efficiency analysis.
