We inherited Summit Heating and AC when we recently bought a house in Oglesby. We called them to install a/c in the house because we didn't know of anyone else in the area to call. Summit had maintained the heating system in the house, so at least they were familiar with the house. We were extremely impressed with the level of knowledge and the professionalism showed by everyone at the company, from the administrative people to the workmen who came to the house. The installation was done on schedule, it was done extremely well, and it was done for a great price. The workers were very conscientious - it was clear that their reputation is important to them. They never tried to sell us something we didn't need, and in fact talked us out of a more expensive system. Summit has quickly earned our loyalty not just with the quality of their work but also with their entire way of doing business.
