Furnace Service FAQ — Larkspur, California
Early fall, before the heating season. You get faster scheduling, confirmed readiness before cold weather, and any needed repairs done without urgency.
Dust and mild mold buildup on the heat exchanger over summer. Usually harmless and clears after a few cycles — or during a professional fall tune-up.
Burner cleaning, combustion analysis, heat exchanger inspection, safety control testing, gas pressure verification, and filter check — all in one visit.
Standard 1-inch filters: every 1–3 months. Thick media filters: every 6–12 months. A clogged filter is one of the most common causes of furnace problems.
Not recommended. Maintenance catches gradual wear that doesn't affect current operation but leads to mid-winter failures. Annual service is the standard.
Annual tune-ups, regular filter changes, and prompt attention to early warning signs can extend furnace life by 5–10 years beyond the average lifespan.
Check that the area around the unit is clear, verify the filter isn't collapsed, and listen for unusual sounds during the first few cycles of the season.
Schedule a pre-season tune-up, replace the filter, ensure all vents are open and unblocked, and confirm your thermostat is functioning correctly.
