Quick answer: The City of Chandler's permit manual lists like-for-like water heater, furnace and evaporative cooler replacements as exempt, but does not list air conditioners or heat pumps, so plan on a permit for AC replacement unless the city says otherwise.
Homeowners often ask whether replacing an air conditioner in Chandler needs a city permit. The short answer: the city’s own manual does not list AC or heat pump replacement as exempt, so plan on one unless the city tells you otherwise.
What the city’s manual says
The City of Chandler Homeowner’s Building Permit Manual (revised April 9, 2026) has a section on work exempt from permit. It lists like-for-like replacement of residential water heaters, water softeners, furnaces, evaporative coolers, water treatment systems and circuit breakers. Air conditioners and heat pumps are not named. It also states that ordinary repairs do not include work on electrical wiring or mechanical work affecting public health or safety.
Typical cases
| Job | What the manual indicates |
|---|---|
| Same-size water heater swap | Listed as exempt |
| Like-for-like gas furnace swap | Listed as exempt |
| AC or heat pump replacement | Not listed as exempt; ask the city |
| New system, addition, or system type change | Expect mechanical and electrical permits |
| Panel or circuit upgrades for a bigger unit | Electrical permit; load calculation may be required |

Why a permit protects you
- An inspector checks electrical connections, disconnects and refrigerant line work.
- Unpermitted work can complicate a home sale.
- Some equipment warranties and utility rebates expect code-compliant installation.
How to check your contractor pulled one
Ask for the permit number before work starts and check it with the city. Also check the contractor’s license with the Arizona Registrar of Contractors.
