For Homeowners
Residential HVAC Design-Build — Not Repair
3rdGen Heating & Cooling is the residential HVAC division / DBA of 3rdGen Building Systems. We engineer and install new high-performance systems — heat pumps, whole-home replacements, remodel HVAC, and ADUs — with Manual J/S/D-informed design, permit coordination, and rebate documentation.
We are a great fit if you need
- Whole-home heat pump retrofits and electrification
- Major remodels and architectural layout changes
- ADUs, additions, and new custom construction
- Complex installs where ducts, zoning, or electrical need real design
We are not the right call for
- Emergency no-heat / no-cool repair calls
- Annual maintenance and tune-ups
- Single-part replacements (thermostats, capacitors, etc.)
Incentives
Rebates, tax credits & financing
High-performance heat pump projects often qualify for federal tax credits and BayREN rebates — but only when equipment, Manual J documentation, and installation meet program requirements. We build rebate-ready documentation into every eligible project.
For eligible scopes, we also support Synchrony financing applications with clear scope and invoice documentation — so you can move forward without guessing what lenders need.
- Federal heat pump tax credit — eligibility guidance and documentation for qualifying equipment
- BayREN & local rebates — equipment selections aligned to current program requirements
- Synchrony financing support — scope clarity and paperwork for financing applications
