Whether a HVAC replacement project triggers Title 24 can depend on the size and scope of the work, and thresholds can vary by local jurisdiction.
Scope and thresholds
Smaller alterations may have simpler compliance paths, while larger HVAC replacement work usually requires full documentation. Because thresholds vary, confirm with your local building department — or send us your scope and we'll advise. Title 24 is a statewide California energy code. HVAC Replacement projects follow the same statewide standards; the exact requirements depend on your project's scope and address, which we model in CEC-approved compliance software.
