Do I need a permit for hvac replacement or installation in Tempe?
Most likely yes. Hvac replacement or installation usually requires a permit in Arizona. Confirm the specifics with Tempe.
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. Replacing HVAC equipment (air conditioner, furnace, or heat pump) is mechanical work that Tempe generally permits under its adopted International Mechanical Code; confirm with permitcenter@tempe.gov whether your like-for-like swap qualifies for over-the-counter permitting. Tempe's Electrical and Gas Clearances handout notes gas water heaters and gas furnaces may not be located in a bedroom or bedroom closet, so verify placement when replacing a gas furnace. Tempe adopted the 2024 I-Codes and 2023 NEC effective July 1, 2026 with a transition through December 31, 2026, so confirm the applicable mechanical and electrical code. 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.
