A/c diagnostic in Hoschton. Indoor unit is in the attic. System is cooling at this time. Fan speed is on high, filter is clean. Outdoor condenser is clean, had to adjust pressures and they are good now. Thermostat is set to 74° and room temperature was at 76°. With testing unit temperature went up to 78°. Did more diagnostic testing on the unit and everything is working properly at this time.
