Hiring HVAC contractors in Vienna

In Virginia, a contractor needs a DPOR licence for any job worth more than $1,000, and the licence class caps the size of a single job: Class C under $30,000, Class B under $150,000, Class A above that. HVAC contractors must also have a master tradesman licence behind the contractor licence. (Va. Code § 54.1-1100) Check the status, class and specialty of any business on DPOR’s License Lookup, or read how to check a contractor’s licence.

Virginia requires a licensed contractor to give you a written contract for residential work before work starts. Permits come from the local building department, and DHCD’s directory of local building officials says who to ask.

On Loclis you describe the job once, licensed businesses send a price or offer to see it first, and nothing is charged until you book. How it works.
