" We upgraded to a new furnace and AC system from Armstrong Air. I really enjoyed working with Jeremy the owner, and he was very professional, gave good information and helped make this process super easy. We were up and running with a new furnace and AC system in less than a week, just in time for the cold weather to hit. We added a media filter, humidifier and an air cleaner, and really notice a difference in our house, especially with two dogs and a cat. I had used them in the past for maintenance issues, and if I continue to use them for my Spring/Fall maintenance, my new system warranty gets extended so easy call. I also got a quote from the Big guys, and Jeremy was more competitive for a better system; plus if I ever have any questions or issues, I know Jeremy and his team will be there. Very pleased. I would always prefer to do business with a local, smaller business than the big corporate guys. "

" Jeremy and his crew are awesome, and have provided incredible customer service. Great honest and reliable service. They took the time to explain what we needed, and the benefits of purchasing one product over another. Also partner with ComEd & Nicor for instant rebates saving a TON of cash. Highly recommended! "
