We've used Garrison and Garrison for years (as long as we've lived in Madison). We actually have their maintenance plan on our systems, so we see them a few times a year. Each time we call, we are treated like the most important customer they have. Their technicians are always really honest about repairs (if any) that need to be done, and their price book keeps me from wondering if I'm getting a fair price. I wouldn't trust anyone else.
