We wanted a second opinion on an expensive proposal from a competitor to remedy a supposed coil leak. The Dolphin technician, Robert, was extremely experienced, competent, professional and inspired our confidence. He gave our air handler a thorough inspection and checked for coil leaks. He confirmed to us that there were no coil leaks and the handler was operating perfectly. This was a great relief to us and I’m sure we will be using Dolphin Cooling again.
