Frequently Asked Questions — HVAC Replacement Permit
What's the difference between an HVAC permit and an HVAC replacement permit?
An HVAC replacement permit is a simplified version for like-for-like equipment swaps. It has a lower fee and faster approval because no new ductwork, venting modifications, or structural changes are involved. A full HVAC permit is needed when installing new systems, modifying ductwork, or changing fuel types.
Do I need a permit just to replace my AC unit?
Yes. Even a straight like-for-like replacement of an air conditioning condenser requires a permit in most Wisconsin municipalities. The replacement permit process is typically quick — often same-day issuance — and the inspection verifies proper refrigerant handling, electrical connections, and clearances.
