Helical wire heating coil assemblies and methods of assembling helical heating coil assemblies are provided. In one example, a helical wire heating coil assembly includes first and second support frames that are detachably coupled together by a first plurality of insulating standoffs coupled to the first support frame, a second plurality of insulating standoffs coupled to the second support frame, and a helical wire heating coil coupled to both the first plurality of insulating standoffs and the second plurality of insulating standoffs.
