I have worked with a few different companies during my previous employment and have found that GGS has provided the best testing method with the most accurate details without impacting the integrity of the refrigeration system. The teams I have worked with in the past have been very professional and focused on their responsibilities which included working safely with our facilities. I continue to promote GGS services due to the detail and solution-based reports that are provided quickly upon completion of the on-site studies as well as the team behind the crew(s) conducting the onsite testing. GGS has been very responsive anytime a question has risen during review of the report.

GGS has been a great partner for our customers. Their technicians know exactly where to look for corrosion and insulation failures, and their site reports clearly document every inspection area. The post‑inspection review call helps us understand all the readings before we present next steps, and their ability to cover multiple sites in one cost‑effective circuit has been a huge advantage for us and our clients.
