About Us

Furnace Improvements Services (FIS) was started in March 1996 in Sugar Land, TX. Our mission is to provide services for improving the performance of existing fired heaters in refineries and petrochemical plants. FIS started with conducting engineering studies for fired heaters and provided solutions to customers to overcome operational problems.

For over 20 years, FIS has been helping end users and owners with design and engineering services to improve the performance and efficiency of their fired heaters, boilers and reduce refinery NOx emissions.

FIS has developed into a full service engineering and consulting company. FIS started supplying new heaters on a turnkey basis in 2002.
