We hired A-1 United Heating and Air to install a new furnace in our house. It's quite different than the last one we had. It's much smaller and it doesn't have as high of a btu rating so there are some cold spots in the house. The guys did a great job of installing it. They worked very hard and everything was fine. They were professional and friendly and they cleaned up after installing the furnace. We filled out the paper to have them come out a couple times a year to do the maintenance for us. We would recommend the company to other people.
