Do I need a permit for hvac replacement or installation in Unincorporated Woodford County?
Yes. In Illinois, hvac replacement or installation generally requires a permit, and Unincorporated Woodford County is no exception.
Most Illinois jurisdictions require a mechanical permit to replace a furnace, air conditioner or heat pump, even for a like-for-like changeout. Gas piping, venting and any new electrical circuit normally require their own trade permit, inspection and pressure test. Which code edition applies is set by your municipality or county, because Illinois has no statewide residential building code for work on an existing home.
