"Proulx has been our fuel dealer of choice for 17 years now. They have provided great flexibility in their programs and support. They have stayed current with technology and equipment. Their technicians have been responsive, well trained, courteous, and professional. I have over 100 rental units that I can't have cold or without hot water. Proulx has been there for us and continues to lead the industry."
