I called Ambient Heating & Air Conditioning company to install the residential air conditioning unit at our house in Springfield. We were so impressed. They responded quickly, gave us a competitive quote on the ac installation, explained all of the ins and outs of the new unit and billed us as quoted once the job was completed. It was really nice to have no surprises. Their service was professional and friendly. We would definitely recommend them to others and would not hesitate in using them again. In fact we have already recommended them to my brother for the commercial air conditioning maintenance at his office.
