One of the first things American Air Conditioning will do is conduct a complete energy analysis of your home. By measuring windows, checking insulation, ductwork and building materials, as well as a variety of other factors, he can determine the right size system and equipment for your home. He’ll even ask you questions about your existing comfort challenges, for example: Are there rooms in your home that are always too hot or too cold? If this is the case, you may need ductwork modifications in addition to a new system.
