My technician was awesome, very nice gentleman and I believe he diagnosed my problem with the best of his knowledge. However I paid for something that did not manifest in his prognosis. Some kind of leak detection was put into my system but a leak was never found. This caused me to be confused because I was hoping the leak would be found, because of the prognosis of the problem. But it wasn’t, other Then that the gentleman was very nice, respectful, and did what he could to resolve the problem.
