Today I arrived on site to address the dye leakage issue in the AC system. Diagnosis and Findings: Identified multiple dye leaks within the cooling module of the 2nd floor AC system. Recommended Action: Replacement of the cooling module is necessary due to the extent of the leaks. When arriving at the client's property. The client explained to me that another company had done a dye test. The company previously diagnosed an R410A leak in the cooling module of the 2nd floor system. I proceeded to verify the system. I found multiple dye leaks in the evap coil. I proceeded to check the condenser coil. I didn't find any leaks in the condenser coil. I showed him to the client and I explained about the situation of the system. I explained that I will submit the information to the office so that he can be contacted to provide you with updates on the replacement of the cooling module. I also recommended the client who should consider scheduling appointments to do the tuneups. View
