Residential HVAC in Marin County
Marin County homes — Mill Valley, Sausalito, Tiburon, San Rafael, Larkspur, and Novato — often need quiet heat pumps and ductless zones sized for hillside lots, marine exposure, and custom residential construction.
Local context
Homes across Marin County
Custom hillside homes, mid-century modern, waterfront properties, and remodels where concealed ductless or compact heat pumps fit better than standard suburban layouts.
Climate
Regional conditions
Marin blends cool bay influence with warmer inland valleys and strong sun on south-facing slopes. Filtration, quiet outdoor equipment, and Manual J sizing matter as much as equipment selection — especially on wooded hillsides.

03
Coordinate & install
Principal-led field work with your GC or architect around access, finishes, sequencing, and clean rough-in.

System startup, basic orientation, and documentation so you know how the new system is meant to run.
FAQ
Frequently asked in Marin County
Which Marin County cities do you serve?
We serve homeowners across Mill Valley, Sausalito, Tiburon, San Rafael, Larkspur, and Novato on whole-home HVAC design-build projects when scope and fit align with our project model.
Are heat pumps a good fit for Marin homes?
Yes, when sized with Manual J for marine exposure, hillside layout, and the home’s specific construction — not rule-of-thumb equipment swaps.
Do Marin projects need quiet outdoor equipment?
Often yes. Hillside and dense neighborhoods make sound planning part of system design, not an afterthought.
Do you provide repair or maintenance?
No. We focus on full-system design-build — remodels, retrofits, and replacements — not service calls.
What is a typical project size?
Most whole-home design-build scopes start around $20k because they include engineering, distribution work, and premium equipment.
