The requirements below come from Oklahoma rules and describe the standard the work must still meet. They are not a statement that Unincorporated Creek County will issue you a permit.
Most likely yes. Hvac replacement or installation usually requires a permit in Oklahoma. Confirm the specifics with Unincorporated Creek County.
Mechanical work requires a Construction Industries Board license; a property owner is exempt only for minor repairs such as cleaning, adjusting, and replacing fuses and room thermostats (59 O.S. 1850.7 and 1850.10(B)(1)). No person may install, replace, or repair gas piping unless licensed under the Mechanical Licensing Act or as a plumbing contractor or journeyman plumber; there is no homeowner exception for gas piping (59 O.S. 1850.10(A)). The 2024 IRC work-exempt list covers only portable heating, cooling, and ventilation units, minor part replacement, and small self-contained refrigeration systems, not replacement of a central system (R105.2, Mechanical). In an incorporated city or town that has not adopted a mechanical code and appointed an inspector, licensed mechanical contractors must notify the Construction Industries Board of the work (59 O.S. 1850.14(G)).
