I looked all over for that, where did you find it? There is an H & H Mechanical (SCC # 04944664-6) in the VA State Corporate Commission (SCC) database, but that was purged on 06-30-07 and WH was in prison from 2005 - 2010. There is also an H & H Mechanical Services (SCC # 0484175-5) - purged 12-31-03 (WH was in Ohio, I believe then) and an H & H Mechanical Contractors (SCC # 0108609-9) purged 12-31-1990. Those were the only "H & H Mechanical" entities in the VA State Corporate Commission database. I also looked for the name under limit liability companies and registered limited liability partnerships.
I posted the link to the Va business registry. it shows it on there.
