Tom started Mattawan Mechanical out of his garage in 1992 after working for two local heating and cooling companies. He knew if he could provide homeowners like yourself with quality workmanship and superior customer service, he would quickly gain trust and reliability from them.

“Tim, the sales rep and the installers from Mattawan Mechanical were very professional. Overly concerned about doing the job properly, proficient, neat and clean. They completed the installation of my new Trane Variable Speed Gas Furnace and High Efficient Heat Pump, in a very protective manner throughout my home. Trane should be very pleased with such representatives of their products, company and integrity of Mattawan Mechanical.”

“Replacing a HVAC system is not my idea of fun or money I really wanted to spend but working with Mattawan Mechanical really made the process less painful. From the initial meeting where we reviewed our current system and determined our new system needs to the final installation of the Furnace, A/C and Hot Water Heater, they were excellent to deal with. Tim, the Sales Manager, was extremely thorough in his discussion of the benefits of Trane over other brands, along with their philosophy to customer service. He is very knowledgeable and was a pleasure to deal with. When I go with a more expensive system, without even questioning myself, I know I made the correct decision. Installation was timely and the crew was extremely courteous and very diligent on keeping the mess to a minimum and making sure we were 100% satisfied. I have worked with a number of Heating/Cooling companies and this was one of the best to deal with. I can’t recommend them highly enough!”

Jeff T. - Kalamazoo, Michigan

“We have used Mattawan Mechanical for all our HVAC needs for almost 20 years. Items they have installed or serviced for us include furnace, air conditioner, water heater, humidifier, and air cleaner. They are professional, responsive, reliable, and well-versed in the latest technology. Their workmanship is high quality and they stand behind it. We are well satisfied with Mattawan Mechanical and recommend them highly.”

Jean B. - Portage, Michigan

“I just had my spring checkup. Everything that Tim told me during the sale has met or exceeded my expectations – it wasn’t just a sales pitch! Never regretted getting our system and grateful we got it through MMS! Right now it looks like I saved between $400-$500 in propane this winter! Electricity was same or a little higher on cooler months from the heat pump usage. Great company from sales to support!”

Larry K. - Kalamazoo, Michigan

“Tom Vaughn and Mattawan Mechanical Services, LLC did an outstanding installation and setup on my Trane furnace and heat pump. I plan to use MMS for service and maintenance in the future. I will also highly recommend MMS to anyone needing HVAC installation and service.”
