Frequently Asked Questions About Furnace Repair in Sunnyvale
How much does furnace repair cost in the Bay Area?
Furnace repair costs typically range from $150-$600 depending on the issue. Simple repairs like igniter replacement or thermostat fixes are on the lower end, while blower motor or control board repairs cost more. We provide upfront pricing before any work begins.
Should I repair or replace my old furnace?
Generally, if your furnace is over 15 years old and repairs exceed 50% of replacement cost, replacement is often the better investment. Newer furnaces are significantly more efficient, potentially saving you 20-30% on heating costs.
Why is my furnace blowing cold air?
Common causes include a dirty air filter restricting airflow, thermostat issues, pilot light or igniter problems, or an overheated system that triggered safety shutoff. Our technicians can diagnose the exact cause quickly.
How quickly can you repair my furnace?
We offer same-day furnace repair service for most issues. Emergency service is available 24/7 with typical response times of 2-4 hours. Most repairs are completed in a single visit.
