Shop for Tires


My name is Chad Tanguay, I am the owner of Merrimack Auto Center and Merrimack Auto Center-Nashua, and I would like to share with you a bit about my business. In 1977 my father, Don Tanguay, started Merrimack 

Auto.  He serviced and maintained the vehicles of many residents and companies in Merrimack and the Greater Nashua area for 27 years. In 1994, after serving in the US Army for 5 years, I reentered civilian life and started working by his side. The greatest attribute that I learned from him was to treat every customer with respect -to be their friend, not just their mechanic. As a member of the Merrimack and Nashua Chambers of Commerce and Board member for the YMCA I know the importance of community and community service and strive to be positive contributor to Greater Nashua.

I have 6 members on my Merrimack team. Don, my father and Merrimack shop manager, Becky, my mother and office manager have both been a part of this business since the start.  Dennis, my lead technician, has been with us since 1977.  Rick joined our team over 2 years ago and brings 30 years of experience. Fred became part of our shop family in 2012 and has been a transmission and drive train specialist since 1984. Neil also came on board in 2012 and has 20 years’ experience as an auto tech and auto body man.

In May of 2013, we purchased our own building and expanded our business into Nashua. My team in Nashua consists of 4 members. Mike, my shop manager, brings 20 years of experience. Jeanne, who was the office manager for Dick Raymond Inc. for over 30 years, also joined our new staff. Abe is our always smiling shuttle driver who will gladly bring you to and from work, and Steve is the commercial account manager for both shops.  Over the years I have gotten to know every customer who has come through my door, and I pride myself in remembering almost every customer’s name. 

That being said let me tell you about some of the services we offer. Here at MAC we service most makes and models with Hondas and Toyotas as our specialty. Along with full size vans and 4X4 trucks, we perform all kinds of services ranging from a basic oil and filter service to full scheduled maintenance. We also offer tires at highly competitive prices, exhaust systems, complete tune-ups, alignments and brake service.  Should you choose to wait while your vehicle is being serviced, we offer free Wi-Fi and coffee in our comfortable and spacious waiting areas. If you prefer not to wait, we will gladly shuttle you to and from work or home. We currently service many fleet accounts including Comcast, Etchstone Properties, Merrimack Water District, Dent Devils Collision Center, Gate City Collision, Merrimack Collision, St. Laurent Collision, Merrimack Premium Outlets, The Stabile Companies, Bailey Towing and Auto Body, Viking Roofing, and Stanley Elevator. I know here at Merrimack Auto we can service all of your fleet needs as well. Please contact us if you have any questions.
