I got quotes from three companies for doing a furnace and duct replacement and a/c installation. Ray Linden who came out from AIS to do the initial scoping and estimate did a great job. He wrote up a proposal right there and handed it to me. I heard good reports and read good reviews about AIS and decided to go with them. They did an absolutely amazing job of managing the process end to end and coordinating with the testing company and asbestos removal company. Finally the crew that came out to do the install were on time and did a great job with the install. Ron, Andrew, and Daniel were courteous and explained everything carefully. They did the install without any disruption to our daily routine. Giao was very prompt in answering my many queries via phone and email. An all around great job.
