Performed a preventive maintenance for air-conditioning system. This maintenance free with new install. Didn’t need to replace the #401 Media Air Filter at this time. Filter was still in fair shape. Customer does supply them. Inspected all the electrical components. Inspected the gravity drain that goes to the French drain 4 feet away. Drain piping is clear flowing without restrictions. Tested the amp draw from the compressor, blower and fan motor. All are operating within manufacturer spec. Tested the temperature split between the supply and return. System is operating at a 20° differential on an 88° day. Wrapped a little bit of insulation around the TXV due to it sweating causing moisture to run down the coil cabinet into furnace. Insulation will prevent it from sweating. Confirmed proper high and low voltages. System is operating properly at this time.
