Hi, My name is Sean. I have been in the HVACR service field for about 4 1/2 years now. I am NATE, ICE, and EPA (universal) certified. I acquired my vocational certificate from DSC here in Daytona Beach Florida. I have joined to look for some answers about some problematic units that either I have installed or done the start-up on. I am looking forward to talking with everyone and also giving any advice I have found over the years.
