California Building Code

California requires carbon monoxide detectors in all homes with gas appliances. After any furnace repair involving the gas valve, burner, or heat exchanger, a CO safety check is mandatory.

Project Timeline

Diagnostic inspection

30-45 minutes

Inspect the furnace visually, check error codes on the control board, test electrical components (ignitor, flame sensor, capacitor, pressure switches), and verify gas pressure.

Component repair or replacement

30 minutes - 2 hours

Replace the faulty component, clean the flame sensor, replace the ignitor, swap the capacitor, or install a new blower motor as determined by the diagnostic.

Safety testing & verification

15-30 minutes

Perform a combustion analysis, check for carbon monoxide leaks, verify temperature rise is within manufacturer specifications, and test all safety controls before returning the furnace to service.

Furnace Repair in Oakland — FAQ

My furnace clicks but won't light — what's wrong?+

The most common causes are a failed hot surface ignitor ($80-$200 repair), a dirty flame sensor ($80-$150 cleaning/replacement), or a faulty gas valve ($250-$600). A technician can diagnose the exact cause in 30-45 minutes.

When should I repair vs. replace my furnace?+

Consider replacement if your furnace is over 15-20 years old, needs a heat exchanger replacement ($1,500+), or has needed multiple repairs totaling more than 50% of a new unit's cost. Otherwise, repair is usually more cost-effective.

Is a cracked heat exchanger dangerous?+

Yes. A cracked heat exchanger can leak carbon monoxide into your home. If a crack is confirmed, the furnace should be shut down immediately and either the heat exchanger replaced (if under warranty) or the entire furnace replaced.

How much does a typical furnace repair cost?+

Most furnace repairs in Sacramento cost $150-$500, including the diagnostic fee. Common repairs like ignitor or flame sensor replacement are at the lower end, while blower motor or control board replacements are higher.
