Dee Cramer is one of Michigan's most trusted names in heating, cooling and ventilation. Since 1937, we have been committed to excellence. Excellence in design, workmanship, competitive pricing and customer service. If you are considering a building or renovation project - commercial, industrial or institutional - you'll want to take full advantage of the latest improvements and technological enhancements available. Thanks to our advanced computer aided design capabilities, Dee Cramer professionals can create heating, cooling and air-exchange systems in detail and to exact specifications, moving quickly from the drawing board to your construction site. The result - a cost effective air flow system seamlessly integrated with your project. At Dee Cramer, we know that the ventilation system is the lifeblood of any structure. How that system functions can either enhance or hamper the comfort and productivity of its inhabitants. In order for the air exchange system to function properly, it must be designed to the architecture, tailored to the owner's needs, correctly installed and be backed by a service department available 24 hours a day 7 days a week. To ensure this happens, you need to work with a company that's on top of the trade. One that knows air systems inside and out, and is in step with all the current codes and standards for the profession as well as the latest in technological and product advances. One that has the professional staff and experience to design, build, deliver, install and maintain a quality system that's done right. Dee Cramer is just that kind of company.
