Thanks — your project details are on their way to 3rdGen. We’ll review them and follow up about the next step.
Project fit
Whole-home heat pump installations, remodel mechanical scopes, ducted and concealed systems, multi-zone equipment, ventilation, and high-end residential projects where mechanical coordination matters before installation begins.
New system
New ducted or ductless heat pump systems sized for your home, comfort goals, and how the house is built.
Heat pump installationFull upgrade
Replace aging furnace and AC together, or convert gas heat to a heat pump with ducts, electrical scope, and controls planned as one job.
Replacement & conversionCentral
Central heating and cooling through existing or updated ductwork, with loads and airflow checked before equipment is selected.
Ducted heat pumpsRoom-by-room
Mini-splits and multi-zone layouts when zoning, architecture, or tight routing make ductless or mixed systems the better fit.
Ductless & multi-zoneCoordinated
Mechanical design and rough-in coordinated with your architect or builder while walls and ceilings are still open.
HVAC for remodelsFresh air
ERV/HRV, filtration, and balanced ventilation coordinated with your heating and cooling scope when the project needs it.
Ventilation & IAQRelevant Marin work
High-end residential remodel
A representative high-end residential project showing the system planning, equipment coordination, routing, and finish-aware execution we bring to Tiburon homes.
The six-zone Fujitsu ductless system was installed, permitted, inspected, and completed as part of the home’s remodel-for-sale scope — delivering zoned heating and cooling without a conventional ducted retrofit.
Representative published remodel scope — location, photos, and full details on the project page.
View projectDesign-sensitive mechanical
On a design-sensitive home, the best mechanical solution is not always the one that is easiest to install. Equipment visibility, ceiling space, outdoor-unit locations, duct routes, zoning, service access, and the architectural plan can all influence the system.
3rdGen approaches the HVAC as part of the building design — evaluating load, distribution, equipment placement, routing, ventilation, access, and long-term serviceability before locking in the system approach.
Tiburon's own housing and design documents describe hillside areas as comprising the vast majority of the town's neighborhoods, with dedicated hillside design guidelines.
Site conditions and elevation changes can affect equipment access, outdoor-unit locations, routing, and installation planning.
Duct routes, registers, returns, concealed fan coils, and service access should be coordinated around the architecture instead of added after the design is set.
Placement should balance system performance with access, sound, visibility, clearances, and the exterior design of the property.
Early mechanical coordination can resolve ceiling space, equipment rooms, duct paths, outdoor equipment, and zoning before framing and finishes make those decisions harder.

Mitsubishi mini-split installed with outstanding care. Indoor and outdoor units done right. High efficiency meant a meaningful federal tax credit too.

Devin and his crew did a fantastic job installing AC for our whole house. High quality Mitsubishi equipment and a clean installation throughout.

On many Tiburon projects, the important decisions happen around the home, the existing system, and the distribution — not from copying the equipment that came out.
Plans, goals, existing system, remodeling scope, and known constraints.
Manual J / system sizing where appropriate, zoning strategy, equipment selection, and distribution.
Indoor equipment, outdoor equipment, duct / refrigerant routing, ventilation, access, and serviceability.
Equipment locations, GC/architect coordination, and permit requirements where they apply.
Rough-in and finish installation coordinated around the project.
Startup, controls, commissioning checks, inspection coordination, and homeowner handoff.
Complete project delivery
A Berkeley electrification project can touch the furnace, ducts, electrical service, controls, equipment locations, permits, and finished interiors. We plan those connections as one scope.
The result is a complete system designed for the home, installed to the plan, and tested before handoff.

Reused, modified, or replaced according to what the design requires.
Capacity, circuits, documentation, inspections, and other trades coordinated with the HVAC scope.
Operation and airflow checked before the project is handed back to you.
Cost
Tiburon projects often vary more by integration than by equipment alone. Ducted versus concealed systems, zoning, access, outdoor-unit placement, routing, remodel conditions, ventilation, electrical scope, and architectural coordination can all affect the final project.
Complex whole-home and design-build projects can exceed these ranges. Rebates and incentives may reduce your net project cost.

Project teams
Many of the residential projects we are best suited for already have an architect or general contractor involved. Early mechanical coordination helps protect ceiling space, views, finishes, equipment access, routing, and the construction plan while the design can still accommodate the HVAC properly.
We work within existing project teams in Tiburon and across Marin — or directly with homeowners when that is the right path.

FAQ
Straight answers on heat pumps, design-sensitive remodels, and project scope in Tiburon.
The answer depends on the architecture and loads. Central ducted heat pumps, concealed fan coils, ductless units, and multi-zone systems can all be appropriate depending on ceiling space, zoning, equipment locations, and the design goals.
Often. Where the architecture supports it, ducted and concealed equipment can reduce visible indoor units. The tradeoffs are available space, duct routing, access, and system design.
Hillside sites can influence equipment access, mounting locations, line routing, drainage, staging, and future service access. Those constraints should be considered during design rather than left entirely to installation day.
Yes. The Town lists furnaces, heating units, air-conditioning systems, ventilation systems, and duct installation among work requiring mechanical permits. Its guidance also notes that separate design review may apply to many exterior items.
Yes. Projects where the mechanical design needs to work closely with the architecture and construction team are among the strongest fits for 3rdGen.
