Clifford Power Systems, is a growing and financially secure enterprise that was launched in 1985. Our goal is to provide the highest quality power generation and automatic transfer switch products available, and then back our products with great service. As a result of steadily increasing demand, we have expanded beyond our Tulsa, Oklahoma headquarters and now have full service branches located in Oklahoma City, Oklahoma, Buda, Texas (in the Austin Metro area) and Mansfield, Texas (in the Dallas/Fort Worth metro area).
