We had them install a humidifier and new Aprilaire Air Filter. We had wanted to go with a mom and pop company but they wanted a lot more money. They came out at 7:45 am 15 minutes early, a great start. They then did the job but they said the duct work needed to be changed. I figured here we go, a resin for more money but no. The held to their price and did not a good job but a great exceptional job. I would recommend them to everyone.
