I wanted to thank you for the air testing and thermography testing you recently completed for us at the US Armed Forces Reserve Center at the Letterkenny Army Depot in Chambersburg, PA. Both yourself and your onsite staff were very considerate of our needs working in and around a project that was still under construction, while at the same time completing your work very efficiently and timely. Both my onsite staff and the inspectors from the US Army Corps of Engineers were very impressed with your active involvement in the testing as well as answering any and all questions that were posed to your team. Your involvement and knowledge of the necessary air and heat loss calculations was key to demonstrating that our facility met the leak rates and thermal loss rates specified.
