When my plumbing leaked and into my furnace enclosure I had a big problem. Temperatures dropping and water leaking everywhere. Called a few places and no one seemed real anxious to help. Then I talked to Dan at AIS. He said he would drop by late in the afternoon to take a look. Well he not only took a look but was a huge help in mapping out how to handle. He removed the heater so the plumber could get to the leaking pipes that evening. the plumber fixed the issue and AIS came in the next day to install my new heater/AC System. From the first call to the office to the final thank you, they were flat out great. Quality of work, service, attention to detail, they even fixed an issue that I had no idea existed. A vent that was covered by the builder and never hooked up properly. I had a great experience working with AIS all around. Price competitiveness was also there. No expediting charges for the work he did even though it was obvious they were busy but I felt my job was the only one they were working on. During my search to find someone to do the work I got estimates on time and cost. The normal response was a week out (at least) and the cost always included a comment about additional charges could apply depending on what they had to do. I was pleasantly surprised when AIS came in where expected and was not only cost competitive but compared to the estimates I received from other companies possibly came in a few hundred less than others. So I will surely use AIS again for any work I have and recommend them as a quality, fair and pleasure to deal with.
