Frequently Asked Questions

Do you offer same-day furnace repair in San Anselmo?

Yes. Our service trucks are stocked locally, so most San Anselmo furnace repairs are completed the same day you call, and we offer emergency service when your heat goes out overnight or on a cold morning.

How much does affordable furnace repair in San Anselmo cost?

We give upfront, honest pricing before any work begins, with no surprise charges. After a quick diagnosis we tell you exactly what the furnace service requires and whether a repair or replacement is the smarter value for your home.

My San Anselmo home has an old gas furnace — is it still safe?

Older gas furnaces common in Ross Valley homes can develop cracked heat exchangers that leak carbon monoxide. As a licensed contractor (CA #501853), we include a combustion and CO safety check with every furnace service and will tell you honestly if it’s time to replace.

Can you replace a furnace in a tight closet or crawlspace?

Absolutely. Many San Anselmo bungalows and hillside houses have furnaces tucked into closets, attics, or low crawlspaces, and our factory-trained technicians size and install gas, electric, and ductless systems to fit your space and your home’s existing ductwork.
