Project fit
Whole-home heat pump retrofits, remodel mechanical scopes, ducted and concealed systems, multi-zone HVAC, ventilation, and residential projects where equipment placement and architectural integration matter.
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.

High-end residential remodel
A representative design-sensitive residential project showing the equipment planning, routing, mechanical coordination, and finish-aware execution we bring to Piedmont 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 projectDesigned around the home
On a Piedmont home, the outdoor unit cannot be treated as an afterthought. Property-line sound, street visibility, setbacks, refrigerant routing, architectural appearance, and service access can all influence where the equipment belongs.
3rdGen considers those constraints alongside load, ductwork, zoning, ventilation, indoor equipment, and distribution so the mechanical system can be integrated intentionally rather than forced into the property at installation.
Piedmont requires outdoor heat-pump sound calculations demonstrating no more than 50 dB at the nearest property line. Its planning exemption for qualifying units also addresses street visibility, setbacks, unit count, and concealment or finish treatment of exterior lines.
Outdoor-unit selection and placement should account for the City’s sound requirement before equipment is committed.
Outdoor equipment and refrigerant or electrical routes should be considered alongside the exterior design rather than treated as purely mechanical details.
Existing framing, ductwork, mechanical spaces, and architectural finishes can affect how a modern heat-pump system is integrated.
Early HVAC planning can preserve ceilings, cabinetry, finishes, equipment access, and concealed mechanical routes during a substantial remodel.
Piedmont requires a mechanical permit for heat-pump work. Outdoor units require a site plan, equipment specifications, Title 24 documentation, and a property-line sound calculation; whole-system replacements involving AC and ducting can also require Manual J load calculations.

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 Piedmont 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
On a Piedmont project, integration can be a major part of the work. Existing ductwork, concealed equipment, outdoor-unit location, sound requirements, routing, electrical scope, number of zones, ventilation, and architectural coordination can all influence 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
For substantial Piedmont remodels, early mechanical coordination helps the architect and builder resolve equipment locations, concealed routes, ceilings, exterior conditions, ventilation, and service access while the project can still accommodate those decisions cleanly.
We work within existing project teams in Piedmont 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, sound limits, and design-sensitive HVAC scope in Piedmont.
The City requires the exterior unit to calculate to 50 dB or less at the nearest property line. Equipment selection and location therefore need to be evaluated before the installation is finalized.
A new unit seeking Piedmont’s Planning exemption must not be visible from the street and must satisfy the City’s other exemption conditions. Projects outside those conditions may require additional Planning review.
Yes. Existing ductwork, architectural finishes, mechanical space, electrical requirements, and distribution simply need to be considered as part of the retrofit.
Yes. 3rdGen performs residential load and system-design work as part of appropriate design-build scopes, and Piedmont specifically requires Manual J in certain whole-system replacement situations.
