Residential HVAC in Lamorinda

Lamorinda homes — Lafayette, Orinda, and Moraga — often need zoned heat pumps and duct upgrades sized for larger floor plans and hot upper floors, not same-size equipment swaps.

Local context

Homes across Lamorinda

Larger single-family homes, hillside construction, and frequent whole-home remodels where existing ducts and single-zone furnaces cannot serve new layouts.

Climate

Regional conditions

Inland Lamorinda sees real summer heat and cooler winter nights compared to the bay. Two-story and hillside layouts amplify upstairs cooling loads and downstairs heating imbalance.

From first call to startup in Lamorinda

01

Tell us about your home

Share location, timeline, plans if you have them, and what is not working today — or what your builder has scoped.

02

Size & design the system

We use Manual J, S, and D where the project needs it to match equipment, ducts, and zoning to the actual house.

03

Coordinate & install

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

04

Startup & handoff

System startup, basic orientation, and documentation so you know how the new system is meant to run.

FAQ

Frequently asked in Lamorinda

Which Lamorinda cities do you serve?

We serve Lafayette, Orinda, and Moraga on whole-home HVAC design-build scopes — heat pumps, replacements, and remodel coordination.

Can you fix uneven upstairs/downstairs comfort?

Usually yes, with zoning and duct/return redesign as part of a whole-system replacement — not by swapping a single furnace.

Do Lamorinda projects qualify for heat pump rebates?

Many whole-home heat pump installs qualify for federal and BayREN programs when equipment and documentation meet current requirements.

Do you work with architects on Lamorinda remodels?

Yes. Many of our Lamorinda scopes coordinate with architects and GCs during design development.

What is a typical project size?

Most whole-home design-build scopes start around $20k because they include engineering, distribution work, and premium equipment.
