Had an AC emergency during this June heat wave and Michiana called first thing this morning in response to my message and were so kind and prioritizing. Kyle did a great job getting me back up and running & look forward to using their services in the near future!

Recently, Ayden completed routine maintenance, and he did an excellent, efficient job. As with all of MM’s employees, he is courteous and took the time to answer my questions so that I could understand the system and its capabilities. Our home is so comfortable, with no hot or cold spots. Very happy with Michiana Mechanical.
