Builders & ADU developers
HVAC for ADUs, SB 9 projects, and new construction
Code-compliant heating, cooling, and ventilation, scheduled around your build. You get a load calc, a written proposal, and dates you can plan around.
What we handle
Load calculations and system design
Room-by-room load calculations and equipment selection sized for the actual unit, not a rule of thumb. Small, efficient ADUs are easy to oversize.
Title 24 coordination
Equipment specs and duct design to your Title 24 energy consultant, and scheduling of required HERS verifications so final inspection isn't held up.
Heat pumps, mini-splits, and ventilation
Ducted and ductless heat pumps, compact air handlers, and the whole-house mechanical ventilation California's energy code requires in new dwelling units.
Scheduled around your build
Rough-in timed to framing and inspections, and trim-out timed to finishes. Dates confirmed in writing, and you hear from us right away if anything changes.
Electrical capacity planning
Early input on the HVAC load so your electrician can plan panel capacity, especially for ADUs that share service with the main house.
Clean closeout
Start-up, commissioning checks, equipment registration, and the documentation your inspector and the owner need.
How a project runs
Send plans or a description: address, unit type, square footage, and where the project stands.
We run the load calculation and send a written proposal with equipment specs for your Title 24 report.
We schedule rough-in to fit your framing and inspection dates.
Trim-out, start-up, and commissioning once finishes are in.
