Work such as central AC replacement, furnace installation, refrigerant-line modifications, and duct changes may need a mechanical or building permit from the local city or county building department. Permit fees, inspection requirements, and submittal rules vary by municipality — ask your installer who will pull the permit and confirm the requirements for your address before work begins.
