Company History

In 1954 Clyde F. Keller Sr. started Keller Heating and Air Conditioning and worked primarily on commercial and residential heating and air conditioning systems. In 1974, the name was changed to Keller Engineering and we became more involved with large commercial/industrial system and pollution control from the tank wash industry. In 1984 while continuing to service and install Heating and Air Conditioning systems, we became more involved in air quality testing. We expanded our expertise to include environmental hazards such as asbestos, lead, and mold. We then provided testing, environmental cleanup, and project design for these services. In 1994 we changed our name to TRF Environmental Inc. and we continue to grow and develop additional services to meet the needs of our customers.
