Found Samsung minisplit system has a sizeable leak at indoor coil indicated by electronic leak detector. Recommended replacement of evaporator coil. Not available at our local distributors so recommended calling installing company to see their availability and warranty coverage. If decide to go with a new system will apply today's diagnostic fee towards the cost of a new system. Please call to set up an estimate if new system is desired over a repair. Checked operation of dehumidifier in crawlspace. Cleaned dehumidifier filter and cycled to check operation. Dehumidifier operates normally and should have no issues maintaining the humidity in the home.
