Furnace repair — Sunnyvale, CA
Last updated: September 24, 2026
What affects the price
HVAC repair costs change based on a few main things. The age and brand of your unit play a big role, as older systems sometimes need parts that are harder to source. The nature of the problem is the biggest factor—a simple capacitor swap is much cheaper than addressing a refrigerant leak or a failed compressor motor. Labor time also depends on how easily a technician can access your equipment in a tight attic or crawlspace. We provide exact pricing confirmed free on the call.
