Greeted customer upon arrival Period Customer LED me to Air handler, thermostat, and condenser. Went outside to see the condenser turns on and it does. Set thermostat to Cooling. Disconnected the condenser from the disconnect box. Lean condenser from inside out. Use chemical and water to clean condenser. Plug disconnected back into power on the condenser, the condenser did not turn on. Issues with Generac box. Troubleshoot the situation, contactor in Generac box is bad. Hardwire the disconnect box directly to the condenser, generic box isn't connected to anything. Condenser turned back on check precious with field pieces check temperature split, temperature split Peak at 18° difference. All readings on pressure were fine except subcooling.
