Project fit
Whole-home heat pump retrofits, remodel mechanical scopes, ducted and concealed systems, multi-zone equipment, ventilation, and substantial residential HVAC projects where modern mechanical systems need to fit cleanly into an existing home.
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 East Bay work
High-end residential remodel
A representative existing-home project showing the system-design and installation decisions that matter when modern HVAC has to fit into the home rather than the home being forced around the equipment.
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.

Alameda has an unusually deep stock of older and architecturally distinctive homes. In that environment, a heat-pump retrofit is not simply an equipment decision. Duct routes, visible equipment, outdoor-unit placement, access, electrical requirements, and finish conditions can all affect the right system.
3rdGen evaluates the home as one mechanical system while staying conscious of the architecture around it. The goal is modern heating, cooling, ventilation, and zoning without treating the building like an empty shell.
The City’s own historic-building guidance notes more than 10,000 Alameda buildings were constructed before 1930.
Mechanical retrofits may need to work around original framing, limited chases, existing finishes, and architectural details worth preserving.
Outdoor units, indoor equipment, ductwork, refrigerant routes, and service access should be planned to reduce unnecessary visual and architectural impact.
Where visible wall-mounted equipment is not the preferred result, central ducted and concealed multi-zone approaches can be evaluated against the space available.
When an Alameda home is already being renovated, early HVAC input can help avoid unnecessary soffits, poorly located equipment, or mechanical decisions that conflict with the design.

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.

Devin is meticulous, methodical, and knowledgeable. Professional crew and a heat pump install we trust completely.

On many Alameda 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
An Alameda 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 projectRemoval and replacement planned around the complete conversion.
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
On an Alameda retrofit, the equipment itself may only be part of the scope. Existing construction, duct routes, electrical requirements, equipment placement, finish protection, concealed-system requirements, and architectural constraints can all change the amount of work needed to integrate the system cleanly.
Complex whole-home and design-build projects can exceed these ranges. Rebates and incentives may reduce your net project cost.

Project teams
On design-sensitive remodels, the mechanical plan can intersect with architecture, exterior appearance, framing, electrical work, finish details, and builder sequencing. Early coordination gives those decisions a chance to be solved deliberately instead of after construction is already committed.
We work within existing project teams in Alameda and across the East Bay — or directly with homeowners when that is the right path.
Mechanical systems coordinated around architecture, ceiling conditions, equipment locations, routing, and finish requirements.

FAQ
Straight answers on heat pumps, retrofits, and design-sensitive HVAC scope in Alameda.
Yes. Older homes can be good candidates, but the mechanical design may need to work around existing framing, electrical conditions, limited duct paths, equipment locations, and finish-sensitive spaces.
Potentially. Depending on available space and the project goals, ducted and concealed fan-coil systems can provide alternatives to conventional wall-mounted equipment.
Sometimes. We evaluate the existing distribution system before deciding whether reuse, modification, or replacement makes sense.
Equipment location, duct routing, registers, returns, access, and visible mechanical elements should be considered early enough that the HVAC system can support the design rather than compromise it.
Yes. Design-sensitive, architect-led, and builder-led residential projects are a strong fit for 3rdGen’s process.
