Furnace Repair en Redwood City — Preguntas Frecuentes

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.
