Arrived to remedy an inoperable air conditioning system. Turned the system on and started inspection at the furnace. Upon inspection of the system found that the metering device was coated in ice. Opened the evaporator cabinet and found that the capillary tubes were coated in ice. Checked system filter and found it had been changed recently. Used inspection camera to check the secondary heat exchanger and evaporator coil for cleanliness, to ensure proper air flow. Inspected the condenser and verified call for cooling. Checked refrigerant levels and found that the system is low on refrigerant. Performed leak search starting with the condenser and lineset. Found that the evaporator coil has multiple leak points. Talked with homeowner about repair and replacement solutions. Homeowner would like to have the evaporator coil replaced. Will reach out to the office and get a time for the coil to be replaced. Charged system to factory specifications to ensure the system will continue to cool be
