Greeted customer upon arrival. Customer led me to air handler, thermostat,condenser. Thermostat was already set to cooling, condenser was on. Unplugged condenser to wash. Plugged condenser back in to check pressures. Put temperature probes to see delta t. Delta T split peaked at 18°F. Pressures were good, subcooling was low but everything else was fine. Unit has been cooling and was still cooling.
