We have over 30,000 square feet of production area dedicated to manufacturing thermostats and related HVAC stand-alone and system controls. We have been in business for over 40 years and have been producing the ACCUSTAT^®, our best-known control, since 1978. We are proud to state that our products are made in the USA.
