Replacing a furnace or air conditioner in Chattanooga can cost enough to cross Tennessee's licensing lines, so ask before you sign. Hamilton County is one of nine counties where a state Home Improvement license is required for residential remodeling from $3,000 to less than $25,000. The state says that license does not cover electrical, plumbing, or HVAC, and that an HVAC contractor may be regulated at the local level. If local rules do not cover the work, the Home Improvement license is required under T.C.A. 62-6-503. A project of $25,000 or more needs a state contractor license in the classification that covers that portion of the job. The city still controls the building permit, so ask which license number will go on it.
