High-end residential remodel

Hearst Remodel

A representative Contra Costa project showing the system evaluation, equipment planning, distribution work, and field execution we bring to substantial Concord residential HVAC projects.

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.

DESIGNED FOR WHOLE-HOME COMFORT

In Concord, a heat-pump conversion needs to perform when cooling demand is real

Replacing a furnace and air conditioner with a heat pump is only part of the project. Duct capacity, return air, airflow, equipment sizing, zoning, and room-by-room distribution determine whether the home stays comfortable when the system is working hardest.

3rdGen evaluates the complete mechanical system before selecting equipment, with the goal of improving both heating and cooling performance rather than simply replacing the existing boxes.

Concord’s certified Housing Element emphasizes preservation and rehabilitation of its existing housing stock alongside new development.

  • Heating & cooling loads

    Equipment should be selected around the home’s actual requirements rather than automatically matching the old system.

  • Duct performance

    A new heat pump cannot correct undersized ducts, weak returns, leakage, or poor distribution on its own.

  • Zoning

    Multi-level homes and distinct living areas may benefit from zoning or multiple systems rather than additional equipment capacity.

  • Remodels & additions

    Changes to windows, insulation, floor area, and layout can alter loads enough to justify revisiting the mechanical plan.

How we work

Heat pump work, start to finish

On many Concord 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

Concord projects can range from straightforward central replacements to whole-home redesigns. Existing ducts, zoning, electrical scope, number of systems, access, ventilation, and remodel conditions are usually what expand the project.

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.

FAQ

Common Questions

Straight answers on heat pumps, whole-home HVAC, and project scope in Concord.

Can a heat pump handle both heating and cooling in Concord?

Yes. Proper sizing and distribution should account for both design heating and cooling loads.

Can my existing ducts stay?

Sometimes. We evaluate duct capacity, condition, leakage, return air, and room distribution first.

Can zoning improve a two-story home?

Potentially. The right approach depends on loads, distribution, equipment configuration, and how the home is used.

Can you work with my contractor during a remodel?

Yes. Remodels are one of the best opportunities to improve distribution and equipment placement while access is available.
