No, turning off the A/C will improve the FE (I notice about a 2 to 3 mpg improvement.) Think about it. The A/C uses electric power. The power has to come from someplace. The only sources of electric power on the TCH are the ICE, regen during costing/braking and the hybrid battery. The ICE will use more gas to make up the power used by the A/C. It just might not be noticable immediately if you have a high SOC on the hybrid battery.
