Service Areas
Based in the East Bay, 3rdGen designs and installs residential HVAC systems throughout select Bay Area communities, with a focus on heat pumps, remodels, new construction and complex mechanical projects.
Where we work
Berkeley, Oakland and the East Bay sit at the center of our service area. We also take on select projects throughout San Francisco, Contra Costa, Marin and the Peninsula when the scope fits our design-build capabilities.

100%
of our residential work is design-build
Berkeley, Oakland, Emeryville, Albany, El Cerrito and Kensington make up the center of our residential service area.
Explore Berkeley HVACWe regularly evaluate remodels, new construction and complex HVAC projects throughout the greater Bay Area.
View All RegionsOur service area depends partly on project scope. Larger remodels, new homes and design-build work may justify travel farther from our core market.
Start a ProjectWhat we do
Our service area is broad, but the work is focused: well-designed residential mechanical systems for replacements, remodels and new construction.
Ducted and ductless heat pump systems designed around the home rather than simply replacing equipment like-for-like.
Explore Heat Pump ReplacementMechanical design and installation coordinated with framing, architecture, electrical work and the construction schedule.
Explore HVAC for RemodelsLoad calculations, equipment selection, duct design, ventilation and mechanical coordination from plans through commissioning.
Explore New Construction HVACMulti-zone, ducted and ductless Mitsubishi Electric systems for projects requiring flexible zoning and thoughtful equipment selection.
Explore Mitsubishi SystemsERV, HRV, filtration and ventilation strategies integrated with the home's overall mechanical system.

Local design
A Berkeley Craftsman, Oakland hillside home, San Francisco Edwardian and new Orinda residence can require very different mechanical strategies.
Older homes often require creative equipment placement, duct routing and retrofit planning that cannot be solved with a one-size-fits-all system.
Marine influence, fog, inland heat and local exposure all affect heating and cooling loads across the Bay Area.
Electrical capacity, architectural constraints, jurisdiction requirements and construction sequencing can materially change the right HVAC approach.
FAQ
Where we work, what we take on, and how project fit affects availability outside the East Bay.
3rdGen is based in the East Bay, with Berkeley, Oakland and surrounding East Bay communities forming the center of our service area. We also take on select projects throughout San Francisco, Contra Costa, Marin and the Peninsula depending on scope.
Yes. Remodels, new construction and more complex design-build projects may be a fit outside our core East Bay market. Project scope, schedule and location all factor into availability.
Yes. We take on select San Francisco residential HVAC projects, particularly remodels, whole-home heat pump systems and projects requiring mechanical design or coordination.
Our strongest fit is residential heat pump replacement, major remodels, additions, new construction, Mitsubishi systems, ventilation and other projects where thoughtful system design matters.
Yes. For remodels and new construction, we can review architectural plans, evaluate equipment options and develop a mechanical approach before rough construction begins.
Not necessarily. Our broader service area primarily applies to installation, replacement and design-build work. Availability for smaller service work may be more geographically limited.
