Licensed New-System Installation & Permitting
Properly Sized, Properly Permitted Installs

New System, Done Right: Hvac Installation in Mill Valley, CA

Ductwork gets evaluated as part of the install, since a new system on old, undersized ducts underperforms.

Written estimates cover equipment, labor, and any necessary duct modifications together.

If you're dealing with an old system finally beyond economical repair, a home addition that needs its own conditioned zone, or a builder-grade unit that's never kept up with the house, you already know an oversized or undersized system installed without a real load calculation will short-cycle, run inefficiently, or never keep the house comfortable — for its entire lifespan.

Hvac Installation FAQ

How do you determine the right size system for my home?+

Matching an old unit's tonnage without recalculating is a common and costly mistake.

Do I need a permit for a new HVAC installation?+

In most jurisdictions, yes — we handle the permit application and schedule required inspections as part of the job.

Will my existing ductwork work with a new system?+

Sometimes yes, sometimes it needs modification — we evaluate this during the site visit rather than assuming either way.

How long does a typical installation take?+

Straightforward system swaps often complete in a day; ductwork modifications or new construction extend the timeline.

What's the real difference between single-stage and two-stage systems?+

Two-stage equipment runs at a lower capacity most of the time, improving comfort and efficiency, at a higher upfront cost.

Do you install ductless mini-splits for additions?+

Yes — they're often the practical choice when extending existing ductwork isn't feasible.

How disruptive is installation day for the household?+

Ductwork modifications or new construction work naturally take longer, and we'll walk through the realistic timeline during the consultation.
