His team at TMi has been the easiest and best company to work with by far. TMi definitely makes it easier to give our customers what they need, and they leave us comfortable knowing that they have our back. Thank you so much for making my job easier!

We partnered with Lennox for over 50 years. It was a great journey. Like every business that has been around for any length of time, the business decides to do things differently. That is the case with Lennox. We have been searching for years for a line of equipment that is distributed by a reputable company that has an excellent representative with a vast knowledge of the industry and really understands customer service to the high level we deliver to our customers. In addition, we want a distributor who has the items in stock, can provide excellent technical support, and provides top-notch training. Daikin-TMI checks all of those boxes so far. I have known Mike Mascia since the days when he was part of the local Lennox team. He was awesome then and that has not changed. Mike understands the industry, our local market, and the very high expectations Al-Don IAQ expects. In addition, I know Mike would only be a part of a team/organization that can and would deliver to meet the needs of the challenges we face today and the future. Daikin-TMI provides the quality of equipment we need to serve our customers along with good technical support and training. We have enjoyed the journey we have experienced with Mike and Daikin-TMI.

Our relationship with Thermal Mechanics goes back nearly 25 years, and during that time they have consistently delivered strong products and reliable support. For the past 10+ years, I?ve had the pleasure of working closely with Dan Rettenmaier, and he has become one of the best equipment reps I?ve worked with in my career. Dan brings a rare mix of technical expertise, responsiveness, and problem-solving that makes him an indispensable resource. He regularly goes above and beyond his role, stepping in to help with whatever our business needs, and we know we can always count on him to get issues resolved quickly. With Dan leading the way and backed by the Thermal Mechanics team, we have a partner who not only provides excellent products but also the service and commitment that make a real difference to our success.
