Ohio's Construction Industry Licensing Board licenses commercial HVAC contractors. Residential HVAC is regulated by the local building department, and Dayton registers mechanical contractors and issues the HVAC permit. An owner who lives in a single-family house may do that house's work after taking out the permit. A rental, or a duplex even when the owner lives in one unit, needs a contractor registered with the city. Kettering and Beavercreek register their own.
