About TSI Technologies

TSI Technologies was established in 1988 to serve the air-conditioning and refrigeration industries. Initially, TSI supplied local and overseas customers with a variety of parts and components that were manufactured in the United States. TSI Technologies built a reputation as a leading supplier to the HVAC industry with high quality parts and excellent customer service.

In 1997, TSI Technologies partnered with an established manufacturing company in China named Wenling Hengfa Air-Conditioning Components Co., LTD. Founded in 1986, Hengfa continues to serve major HVAC customers in Southeast Asia including Fujitsu, Hitachi, York, and Samsung. TSI Technologies introduced Hengfa to the United States and other global markets serving customers such as Carrier and Rheem. Over 600 employees work in the Wenling plant located in the province of Zhejiang. The modern plant occupies over 155,000 square feet of manufacturing, warehousing and office space.
