I was delighted and really impressed with DALCO Heating & Air Conditioning because they were very helpful and very prompt when I called them. They fixed my air conditioning unit in the front and in the back because I have a large house that needed work on both sides. The tech was very understanding about the problems we had and made sure I had their number. He was just very prompt and I appreciated his help. And I really like that it took an hour or two hours for them to come out after I called, as it was getting uncomfortable in the house. I liked his fast response time and that he fixed it, and everything is working real well now.
