Requirements to Obtaining your License
The person applying for an HVAC contractor registration shall be the owner of the contracting business, a partner in the contracting business applying on behalf of a partnership, or the chairman of the board or chief executive officer applying on behalf of the contracting corporation.
To obtain a contractor's license, you must also apply for a business credential.
Work that can be Done Under this License
A dwelling contractor-restricted category is for projects under $25,000, for contractors who provide a surety bond of less than $25,000. The figure of $5,000 mentioned in 101.654(2)(a)1, Stats. is the minimum for providing a surety bond. That minimum only is valid for the restricted category; there should be at least a $25,000 bond for the "full" or unrestricted dwelling contractor category, if a bond is provided and not the certificate of insurance.
