Testimonials

“It has been a pleasure working with JL Service Group, especially Mr. Harmon and his company for the last two years on Ft. Bragg. Their people have always been extremely responsive, professional, and knowledgeable, but the biggest praise I must give them is that they were always on time and met deadlines, which is more important than anything when your performing federal contracting work.”

James Davis

President, Corporate Military Contracting Inc.

“Jonathan and his team at JL Service Group are conscientious business partners who exhibit a sense of urgency for any issues that may arise. On numerous occasions, the JL Service Group team has demonstrated that they care about my business. Specifically, our firm required the removal of aged, old Libert systems and the installation of two new Liebert systems to sustain our server rooms. With a tight deadline, they were able to complete the project on time. Throughout each phase of the construction process to final completion they were a collaborative partner. I trust their expertise and knowledge to maintain our current systems on an ongoing basis and would highly recommend them as a partner with any HVAC projects, existing or future.”

Cathelene Thomas

Chief of Staff, RAILINC

“JL Service Group’s most recent project with us was to replace some aging rooftop units on our building. Even in this crazy time of supply chain issues and equipment delays, he was able to track down equipment and get us taken care of in a matter of weeks, not months. His crews are professional, sensitive to working in occupied spaces, and effectively communicate with our superintendents, tenants, and owners.”
