This is my first time using Encore Air. I looked them up on the computer and they had good reviews that said how good they were and all that stuff. So I decided to go with Encore to have an air conditioner and heater installed. I am very happy with them. I haven't had any problems. The only thing is, when I call up Encore Air, they don't answer since their answering machine was totally filled up and cut me off. But I would still want to continue using their service.
