About

3rdGen Heating & Cooling is a Berkeley, CA-based HVAC design-build firm operating within a 25-mile Bay Area service radius, with a 5/5 Google rating from 200 reviews and more than 850 systems installed across 11 years in business. 3rdGen focuses exclusively on project-based residential HVAC work — heat pump installations, furnace-to-heat-pump conversions, full-system replacements, remodels, retrofits, new construction, and ADUs. The company does not offer emergency repair, routine tune-ups, or small service calls, making it best suited for property owners and residential builders planning scoped HVAC projects rather than reactive maintenance. All projects are supported by in-house Manual J, Manual S, and Manual D load calculations, meaning equipment sizing, system selection, and duct design are based on the specific building rather than rule-of-thumb estimates. 3rdGen holds California Contractor License 1086898 and is a Mitsubishi Diamond Contractor with factory certification and training. For property managers overseeing residential buildings, ADU additions, or remodel projects in the Bay Area, 3rdGen coordinates directly with architects and general contractors on equipment placement, duct routing, zoning, and finish integration before rough-in is locked in.

Manual J is a load calculation method that determines the correct heating and cooling capacity for a specific building; Manual S guides equipment selection and Manual D covers duct design. 3rdGen Heating & Cooling performs all three calculations in-house to ensure systems are sized and designed for the actual structure rather than based on guesswork.

3rdGen Heating & Cooling is structured to coordinate directly with residential architects and general contractors on remodels, new construction, and ADU projects.
