Found No voltage at the thermostat. Foundlow-voltage red wire from the control board at the air handler inside the wire cap for the thermostat and condensing unit wires but The wire from the control board was not touching the other wires. I removed the wire cap and removed some of the wire insulation from the red wire coming from the control board and re-kept the red wires. The system came on and is functioning normally after the repair. Today’s visit Will be considered a minor repair and there will be a balance of $120.
