100% satifaction
Once upon a time, when you did business with National Refrigeration, you shook hands with one man—Jack King, Sr.—and he got the job done.
Even though we’ve grown to accommodate thousands of homes and businesses in Rhode Island, we still like to treat all our customers with the personal service which Jack founded the company on.
