Do I need a permit for hvac replacement or installation in Chandler?
It depends. Whether hvac replacement or installation needs a permit in Chandler comes down to the details of your project.
Most Arizona jurisdictions require a mechanical permit to change out an air conditioner, heat pump, or furnace, even for a like-for-like swap; the specific permit type and inspections depend on the local adopted code. Adding a new electrical circuit or gas line for the equipment, or relocating it, can trigger additional electrical, plumbing, or structural review. Chandler's manual exempts like-for-like replacement of furnaces and evaporative coolers, but a swap that alters electrical wiring, gas piping, or relocates the unit is not an ordinary repair and needs a permit. Air conditioners and heat pumps are not named in the manual's like-for-like exemption list, so confirm with the Plan Reviewer of the Day (480-782-3078) whether your specific replacement needs a permit before starting. Chandler adopted the 2024 International Codes and 2023 NEC for plans submitted on or after July 1, 2025; verify current mechanical and electrical requirements rather than relying on generic Arizona guidance. A new or relocated system, or one that burns gas, goes beyond a like for like change out and is not covered by replacement exemptions. Gas piping and venting normally require their own permit and a pressure test, and a relocated system usually triggers new duct, condensate, and electrical disconnect requirements.
