Do I need a permit for hvac replacement or installation in San Antonio?
Yes. In Texas, hvac replacement or installation generally requires a permit, and San Antonio is no exception.
Replacing or relocating HVAC equipment requires a mechanical permit in most Texas cities, and many issue same-day express permits for like-for-like changeouts. Changing equipment location or adding electrical or gas connections can add trade permits and inspections. Confirm the scope with your local building department. The DSD Home Remodeling FAQ requires a mechanical permit to install HVAC equipment, exhaust fans, kitchen hoods, and dryer ducts, so a change-out is not exempt. Only a Texas state-licensed contractor can pull an electrical, mechanical, or plumbing permit in San Antonio; a homeowner generally cannot self-pull the mechanical permit for HVAC. Standard residential change-outs are often handled quickly through BuildSA or over the counter at the Cliff Morton One Stop; confirm the current fee on the DSD fee schedule.
