Commercial mechanical · Bay Area
Coordinated HVAC systems for commercial, multifamily, and high-end residential projects where design decisions matter before installation starts.
Project Proof
A focused look at the commercial, institutional, VRF, and high-end residential scopes 3rdGen is built for. These are not portfolio fillers — they show the level of coordination, system complexity, and project context we're trusted to handle.
Commercial Berkeley, CA
GC-led Berkeley retail tenant improvement with a Mitsubishi four-zone ductless system, fresh air supply, exhaust ventilation, and louver coordination in an active commercial space.
Commercial Tenant Improvement
Commercial Berkeley, CA
Commercial HVAC upgrade for an institutional religious facility in Berkeley, delivered in coordination with VRGC Inc. and the project team around existing building conditions, access limitations, and closeout requirements.
Institutional Upgrade
Residential Berkeley, CA
GC-led residential remodel in Berkeley with a six-zone Fujitsu ductless heat pump system and two outdoor units, coordinated around an older existing home being prepared for sale.
High-End Residential Remodel
Mechanical systems for projects where coordination matters before installation starts.
Full mechanical scope for commercial projects — from design through installation, coordinated with the GC, design team, and project schedule.
Learn more →Complex commercial and residential VRF systems with attention to equipment placement, refrigerant routing, zoning, access, and startup requirements.
Learn more →Full-system retrofits, remodels, new construction, heat pump conversions, and design-build HVAC for Bay Area homes where comfort, layout, and finish details matter.
Learn more →Mechanical scope for tenant improvements — coordinated with the GC, design team, and project schedule to meet building department and owner requirements.
Learn more →Mechanical systems prepared for controls integration by the BAS or controls contractor.
Learn more →Repeatable HVAC systems for multifamily and mixed-use projects, coordinated around unit layouts, ventilation needs, equipment access, and construction sequencing.
Learn more →A principal-led process built around scope clarity, coordination, and field execution.
01
We review the project context, drawings, site constraints, schedule, and mechanical intent before pushing toward equipment or pricing.
02
We help clarify system approach, load requirements, equipment placement, routing, access, and coordination risks early.
03
We work with the GC, architect, engineer, and other trades to reduce field conflicts and avoid avoidable rework.
04
Our team executes the mechanical scope with attention to sequencing, workmanship, startup, and closeout.
For GCs who need mechanical scope handled clearly, coordinated early, and executed without unnecessary handholding.
Mechanical Support for GCs →For architects who need early HVAC input on equipment placement, routing, aesthetics, load requirements, and design-sensitive constraints.
Coordination for Architects →For mechanical engineers and consultants who need field execution aligned with design intent, documentation, and system requirements.
Working With Engineers →For owners evaluating full-system retrofits, remodels, VRF systems, heat pump conversions, or technically involved residential HVAC scopes.
Residential Design-Build HVAC →3rdGen is a lean, principal-led mechanical design-build firm. The same people responsible for scope, coordination, and project decisions stay close to the work through installation.
That structure matters on complex projects. Commercial interiors, institutional upgrades, VRF systems, and high-end residential remodels all depend on early decisions that can create field problems later if they are missed.
We are built for project teams that need a mechanical partner who can think through the scope, coordinate with the right people, and execute without turning the work into a management burden.
Practical notes on coordination, VRF systems, controls-ready infrastructure, and design-build HVAC decisions that affect real projects.

Why we rough-in with BAS compatibility and commissioning clarity from day one.
Send the project context, location, timeline, and mechanical scope. If it looks like a fit, we'll follow up to discuss the right next step.
3rdGen is best suited for commercial mechanical scopes, VRF and multi-zone systems, multifamily work, institutional upgrades, and full-system residential remodels or retrofits. We are not structured around small service calls or emergency repair work.
