About Us

MTB Mechanical is a family owned and operated business that has installed and repaired heating and cooling systems in the greater Charlotte area for more than 40 years.

We have managed to earn the loyalty of our customers by providing high-quality work at reasonable prices.

What Makes Us Different

We provide up-front estimates and charge by the job, rather than by the hour, which takes the guesswork out of your heating and cooling service bills.

Our managers have established long-term relationships with a variety of suppliers, which means we can secure the necessary parts for a job quickly and get your system up and running in short order.

Our technicians are trained both in-house and in classes offered by manufacturers and distributors, which keeps our workers up to date on the latest HVAC technology.

MTB Mechanical provides service and installation to families and businesses throughout the greater Charlotte area.

Britt Thomas & Dan Miller


In 1976, Dan Miller recognized the need for better service and professionalism in the heating and air conditioning industry and started his own business, Miller Refrigeration, offering top-notch service. He quickly added other types of work until he was providing the full spectrum of HVAC services to homes and businesses in the Charlotte area.

Dan’s daughter, Jennifer Miller Thomas, knew she wanted to follow in her father’s footsteps. After college, she and her husband Britt Thomas started MTB Mechanical and began serving the heating and cooling needs of the Charlotte area. 

Shortly after Jennifer and Britt got their own business running smoothly, they talked to Dan about emerging from retirement. He agreed to join the business and brought with him 37 years of HVAC knowledge and experience.

With two generations now running the company, MTB Mechanical is able to offer both experience and youthful enthusiasm. 

It’s possible a third generation may one day join the company. Jennifer and Britt have started a family, and they hope their own children will carry on the tradition of serving the heating and cooling needs of the Charlotte area with high standards for top-notch service.

Our office hours are 7:30 a.m. till 8:00 p.m. Monday through Friday and on Saturday and Sundays we have staff here from 8:00 a.m. till 5:00 p.m. We recognize that your heating and cooling systems often fail at inopportune times so we hope to make it easier on you by having employees to service your HVAC needs for extended hours. Our technicians are well trained and have fully stocked trucks so that most parts are available on the spot.

We want to make you a customer for life. Our service techs are knowledgeable and trained to educate you on your heating and cooling system. We will never sell you something you do not need. We will explain any problems with your equipment and give you the information that you need to have to make an informed decision moving forward.

If you need to replace your equipment our Comfort Specialist can assit you with making the best and most efficient decision on new equipment. They can give you cost options and efficiency options to meet your needs and concerns. We are there after the sale to make sure that you are happy with your new equipment and our performance. We want to keep you as a customer for life.

Our family-owned company is proud to have provided heating and cooling services to the greater Charlotte area — an area we also call home — for more than 30 years. We have made it our priority to hire experienced and professional technicians who meet our standards for the highest quality of work. Whether it’s repairing a broken mechanical system or installing a new one, our customers know that we make it our business to provide them with what’s best for their family.
