770-924-1343 Ventilator King Acworth reviewsbr New Reviewbr br Great Price for Excellent Service! I saw the Ventilator KingInsulation King truck down the street doing work and decided to ask for a price and a quote for insulation for my attic. I had other quotes from other companies, but none that was close to Ventilator King. The guys did a very good job of keeping the mess to a bare minimum and the attic fan and insulation have helped to lower the number of times our AC kicks on significantly.
