About Us

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.

I have had the pleasure to work with Jonathan Harmon on various projects over the last couple of years and would without hesitation recommend him for commercial HVAC work. McKenna Construction completes public and private projects that range from interior fit-ups to multi-story office buildings and conditioned storage facilities. We would be comfortable with JL Service Group tackling any of those projects and know that Jonathan and his team would work closely with us to keep the projects within budget and on time.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.

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.
