Maury County generally does not require a mechanical permit for this class of ductless work. Spring Hill, Williamson County, Columbia, and Franklin commonly do for new installs. On sold+installed tickets we pull what the AHJ wants.
Wholesale pickup customers handle their own permitting path. Call 931-982-8253 if you are unsure which side of the line you sit on.
