I have worked with PEBL on several projects and they have always been very professional and easy to work with.  Water Gleye and his team bring a wealth of experience and their test and balancing results have proven accurate.  PEBL does not simply subscribe to the balancing side of Test and Balance; rather is very engaged and detailed in the testing as well as balancing to ensure that the final product functions and performs as intended.
