The Dean Mechanical Story
Dean Juntunen, the owner of Dean Mechanical, grew up in Livonia and graduated from Detroit Engineering Institute in 1983. Upon graduation, he worked as a heating and cooling service technician.
Due to his technical expertise and interpersonal skills, he quickly became a service technician manager with several technicians reporting to him. Dean’s honesty, knowledge, and friendly demeanor made him a favorite with customers. In 2002, after years of experience and acquiring knowledge of best practices in the HVAC industry, Dean decided to venture on his own.
Dean Mechanical is a fully licensed and insured family-owned and operated business that employs 11 people and operates 7 service trucks. We provide service to local commercial and residential customers in Wixom and the surrounding areas. We enjoy helping and interacting with home and business owners, providing them with the assistance they need to stay comfortable year-round. During regular business hours, our customer phone calls are answered by office staff, not by an answering machine or voice mail.
