I pay around $500/year to maintain my ATU unit and have it tested. My contractor is certainly licensed by the state and does an excellent job. I should NOT have to pay an additional $75 for VDH to do inspect my unit. If they want to inspect it, that is great. I respect the fact that they want to ensure that diseases are not being spread. However, I already pay plenty to maintain my unit!  This additional fee is a tax! I already pay my taxes.
