I had 2 23-year old Carrier AC and furnace units replaced. The Colony crew was great. Very happy people who seemed to like working together. The install took all day till 7:00 in the evening. They took care of everything until it was done. My house is 40 years old so they had to bring it up to code, replace some copper running new lines in the attic, replacing soft ductwork connected to the hard ducts. They did a great job. My system is silent and is working well!
