Frequently Asked Questions

Do you offer same-day furnace repair in Mill Valley?

Yes. Our trucks are stocked for same-day furnace repair across Mill Valley, and we fix most furnaces on the first visit. We’re licensed (CA #501853) and serve the canyon neighborhoods and the Tam Valley and Strawberry flats alike.

How do I know if I need furnace repair or a full furnace installation in Mill Valley?

If your furnace is under 15 years old and the issue is isolated, repair is usually the right call, and we always try that first. For older units with a cracked heat exchanger or repeated failures, a new furnace installation is often safer and cheaper over time, and we’ll size it correctly for your home.

Why do furnaces fail faster in Mill Valley than in drier parts of Marin County?

The marine fog off Mount Tam and damp crawlspaces under hillside homes speed up rust on heat exchangers, flues, and ductwork. Annual furnace service catches that corrosion early, and our furnace service covers homes throughout Marin County.

Can you install a furnace or heat pump in an older hillside home with tight access?

Absolutely — steep, contour-following lots are routine for us. We handle attic, closet, and crawlspace installs in Mill Valley’s older Craftsman and mid-century homes, and we’ll walk you through whether a high-efficiency furnace or a heat-pump conversion fits your house and budget.
