I appreciated the politeness & persistence of their techs. With the exception of the first visit when the tech told us we just had a dirty filter, I feel like we had excellent service. Venny and Ben, the techs that came out the next 2 days, worked hard to figure out the problem with our ac. When nothing could be found after a system reset, Venny was out the next morning again to find the problem & they did. I would call out AC Wizard again. They would get an excellent review from me if it weren't for the tech on the first visit.
