"Tom, the heating and A/C service manager, and Kristi, the vice president, helped with our installation from beginning to end. Tom was incredibly wonderful with communication, explaining every detail patiently, and always trying to give me a heads up if anything was a little different than planned. I had called A.W.E. to help with our steam boiler system. Another company (Four Seasons) had installed a new steam boiler in our house, and the boiler had caused corroded steam pipes in the basement to burst, resulting in extensive damage to the house. My first thought had been to repair or replace the boiler and to fix the corroded pipe. However, Tom and Kristi explained quite patiently to me that because of the age of our house and the fact that multiple visible steam pipes were extensively corroded, it was not a wise idea to have a new steam boiler in our home. They explained that any new steam boiler is stronger than an old steam boiler (ours was at least over 20 years old), which most likely had been winding down for some time. They explained that when the new steam boiler pushes hot steam through the system, corroded pipes are likely to rupture. They also explained that many of these pipes are inaccessible behind walls, and if there is extensive corrosion on visible pipes, there is almost certainly corrosion on the inaccessible ones. Finally, when the necessary chemical flushes are done to clear the system of mud and debris, these chemicals can actually remove the debris that was patching holes in corroded pipes and thus facilitate bursting of pipes. We are obviously not experts in the field, but all of this made a lot of sense. It would have been easier for them to try to fix the boiler and the ruptured pipes, charge us money, and then throw their hands up in the air denying responsibility when things continued to go wrong. Instead, they turned down the job and its money because they felt repairing or replacing a steam boiler in this situation was very unwise for us. After a lot of thought, we asked A.W.E. what they would recommend, and they suggested that we try to figure out a way to install forced air heating and A/C in our house. Tom spent hours at our house, and likely hours in planning on his own I'm sure, figuring out how to make things work. He ended up using vents we already had for our existing A/C system, modifying them to make them better, and installed two separate furnace and A/C units on the first floor. Because we had never had a forced air heating system before, the spaces where the units had to fit were tight, but they made everything work. Our son was also a baby at the time, and the crew tried their best to do quieter work when the baby was napping. They also tried to be considerate with cleanliness during the project, as we had four children running/crawling barefoot around. I have been so cautious with praising them given a past terrible experience with the other heating and A/C service. I have not posted for several months, just in case things fell apart. But, it has been 3 months, and things have not fallen apart. We have very good heating and A/C on our first floor. We have fairly consistent temperatures; I would say that there is surprisingly little temperature variation between the rooms now, considering how old and drafty our home is. The Nest thermostats work well. The service technicians seem to adapt to my type-A personality and my many questions, and do their best with timeliness and cleanliness. For the most part, the techs always are polite to me, even at those times in the past when I was upset. I am sure A.W.E. is not perfect, as no company is perfect. But, it seems to be me that they are more honest and have more integrity, and try harder to do right by their customers, than any other heating and A/C company that I have ever encountered. I really hope that they stay true to themselves and continue to do the best they can, as they surely truly did with us. We are so thankful for them and to them."
