CAMBRIDGE RETROFIT BUILDING STUDY PROGRAM

Cambridge offers a Retrofit Building Study Program that is unmatched in the industry. This service is provided at no cost to the installing contractor or building owner to verify the performance of our heating system after it is installed in their warehouse, distribution center or manufacturing facility. Temperature loggers document balanced temperatures throughout the building. Utility bills show the energy savings. Here are some examples of actual savings for facilities that have already replaced their original heating system with more energy efficient Cambridge Blow-Thru heating technology.
