Recent Review: Our heat pump/AC unit (18 years old) was making a lot of noise and seemed to be laboring to heat the house, so we called Chiltroll, based on the ratings they had received here on Angie's List. The technicians who came out were polite, prompt, and knowledgeable and thoroughly explained our options to us. Based on their recommendations and our own research, we decided to replace the entire heat pump/furnace system with a new Trane XL16i heat pump, an Aprilaire air cleaner, and a humidifier. Chiltroll did a good job of showing up when they promised to be here, doing the work promptly and neatly, and following through quickly when the county inspection showed there was one little item that needed to be fixed to pass inspection (adding insulation around the pipe for the humidifier). Their workers were professional, courteous, and knowledgeable. The new system is working great!
