Virginia requires contractors to hold a Class A, B, or C license with an HVA specialty from DPOR, with Class A demanding five years of experience for projects over $120,000 and smaller licenses for less extensive work.

For those trying to budget, a service call runs $75 to $200, a routine tune-up for a single system costs $70 to $200, and a standard repair averages $150 to $1,200, with final costs depending on what the system reveals once a technician opens things up.
