Jack R.  – CEO/Visionary

Jack has over 45 years of experience in the HVAC industry. He originally became interested in this field because his father was a lead mechanic for United Airlines. As a result, he was constantly exposed to various types of mechanical repairs. As a high school student, Jack attended Vocational Technical School, specializing in HVAC. During summer breaks in high school, he began working for General Marine Refrigeration and was placed at Atlantic Refinery as their primary service technician. After graduating from Ridley High School he continued to work full time at the Refinery. While working full time, Jack also attended Widener University to earn a B.S. in Business Administration. Upon graduating in 1983, he started working for one of the largest mechanical contractors in the Philadelphia area, Delaware Valley York. Jack was hired as a Sales Engineer and began learning Design Build projects focused on industrial applications. To expand his knowledge of Controls, Jack took a position at Barber Coleman for two years where he learned DDC, pneumatics, and electronic controls. He continued to build on his knowledge by joining another large mechanical contractor, AT Chadwick. He spent a few years there as a Sales Engineer, specializing in heavy tonnage equipment. In 1989, he was approached by Chris Wilhelm at Wilgro Services. The owners of Wilgro Services were looking for an exit strategy and they found their answer by hiring Jack Rinkers. Jack started to help the company ownership by diversifying their contract base to include both public and private sector work. Simultaneously, he was doing all of the Design Build services for the organization. In 1992, he purchased all of the shares of the company and retired both owners. Under Jack’s leadership and knowledge, Wilgro Services, Inc. has grown to be one of the largest non-union commercial HVAC contractors in the Philadelphia area. He is actively involved in the day to day operations of the company and oversees the Design Build division. Jack enjoys being in the field and helping our clients solve their most complex HVAC problems.
