Can you design HVAC with minimal visible equipment?
Often. Ducted and concealed systems can be evaluated where the architecture provides enough space and access.

High-end residential remodel
Hearst Remodel
A representative Marin project showing the mechanical planning, architect coordination, equipment integration, and finish-aware execution we bring to Ross residential work.
- Home type
- Existing home, remodel for sale
- System
- Fujitsu multi-zone ductless heat pump
- Mechanical scope
-
- · Six indoor wall units
- · Two outdoor units
- · Wall-mounted outdoor brackets
- · Refrigerant routing and field coordination
Challenge
- Existing older home with limited equipment placement options
- Outdoor units required side-yard wall bracket mounting
- Finish-sensitive interior installation
- Coordination with the general contractor’s remodel schedule
3RDGEN scope
- Six-zone ductless heat pump installation
- GC-led remodel coordination
- Permit and inspection support
- Startup as part of the completed remodel scope
Outcome
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.

View projectDESIGN-SENSITIVE MECHANICAL
In Ross, the best mechanical system is the one the architecture can actually live with
Equipment placement, ceiling space, visible registers, outdoor units, duct routes, access panels, sound, and serviceability can all affect a high-end residential design. HVAC decisions therefore need to happen early enough to become part of the architecture rather than a compromise made after it.
3rdGen evaluates load, distribution, zoning, equipment placement, ventilation, routing, and service access as one coordinated mechanical system.
Ross has an established design-review process, and the Town specifically encourages property owners to work with architects and other design professionals early on larger projects.
-
Architect-led projects
Mechanical planning can be coordinated alongside ceilings, cabinetry, structure, lighting, and finish conditions.
-
Concealed systems
Ducted and concealed fan coils can reduce visible mechanical equipment where the building allows it.
-
Outdoor equipment
Placement should balance performance, sound, access, landscape, architecture, and future service.
-
Hillside properties
Ross has specific hillside review for qualifying steep properties, making site-aware coordination especially important on affected projects.

Heat pump work, start to finish
On many Ross projects, the important decisions happen around the home, the existing system, and the distribution — not from copying the equipment that came out.
01 — Project review
Plans, goals, existing system, remodeling scope, and known constraints.
02 — Load & system design
Manual J / system sizing where appropriate, zoning strategy, equipment selection, and distribution.
03 — Equipment & routing
Indoor equipment, outdoor equipment, duct / refrigerant routing, ventilation, access, and serviceability.
04 — Permit / coordination review
Equipment locations, GC/architect coordination, and permit requirements where they apply.
05 — Installation
Rough-in and finish installation coordinated around the project.
06 — Startup & closeout
Startup, controls, commissioning checks, inspection coordination, and homeowner handoff.
Complete project delivery
The whole heat-pump project—not just the outdoor unit
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.
Tell us about the project-
Existing equipment and gas heat
Removal and replacement planned around the complete conversion.
-
Ducts, zoning, and controls
Reused, modified, or replaced according to what the design requires.
-
Electrical and permitting
Capacity, circuits, documentation, inspections, and other trades coordinated with the HVAC scope.
-
Startup and commissioning
Operation and airflow checked before the project is handed back to you.
Cost
What a whole-home heat-pump project costs — and what moves the number
Ross projects are often driven by integration rather than equipment price alone. Concealed systems, multiple zones, extensive ductwork, difficult access, outdoor-unit siting, ventilation, electrical scope, and architectural coordination can all expand the project.
Scope Typical 3rdGen Project Range What drives it
Ducted heat pump, existing ducts usable $20k–$30k Equipment tier, capacity, controls, condenser location and access
Ducted heat pump + duct repair or resizing $25k–$45k Amount of ductwork replaced, crawlspace or attic access, return-air changes
Ductless multi-zone, 3–4 heads $25k–$40k Head type, line-set length, routing, concealment and finish conditions
Whole-home ducted + ductless combination $40k–$80k+ Multiple systems, zoning, ductwork, filtration, ventilation and architectural coordination
New construction system $20k–$50k+ Building size, system count, Title 24/design requirements and coordination with the build
ADU system $8k–$15k Zone count, head type, line-set routing, and whether the ADU shares the main house or stands alone
Electrical panel upgrade, when required $8k–$10k+ Service size, meter location, utility requirements and site conditions
Complex whole-home and design-build projects can exceed these ranges. Rebates and incentives may reduce your net project cost.

Project teams
Built to work with architects and builders
These projects are strongest when mechanical requirements are resolved while architecture and construction details are still flexible. We coordinate equipment locations, distribution, service access, and routing with the larger design.
We work within existing project teams in Ross and across Marin — or directly with homeowners when that is the right path.
