Originally founded as an electrical company in 1972, our founder Karl Mittermayr quickly recognized the growing importance of heat pumps in the future, which were widely unknown at that time. Through targeted investing in research and development wich commenced in 1979, the company was able to secure itself a distinct role in the industry through numerous innovations and patents.

The two sons, Dominik and Klemens Mittermayr, assumed leadership of the organization in 2001.
With the increasing demand for our products and services, the number of employees has multiplied and the company´s facility has doubled to an area of 1.500 sq.m. In parallel with this growth in the heat pump and heat recovery industry, M-TEC has also been successfully expanding capabilities into the areas of refrigeration and ventilation technology. A complementary activity in the field of photovoltaics has alsohelped to expand the energy conscious portfolio of products and service.
