Aadvanced Aair had the best bid out of three companies after a test revealed high levels of radon. Installers arrived promptly on schedule and completed work in a timely manner. No mess. Work looked good. I was told a retest would be done after letting the system work for a day. The retest did not start when I anticipated. I needed to make a couple phone calls and send an email and we got things back on track without problems. The retest showed the radon was successfully mitigated. I would have no problem using Aadvanced Aair again.
