Does Turning on the AC Increase Fuel Consumption?

Turning on the AC does increase a car's fuel consumption. The reasons are as follows: 1. When the car's air conditioning is in cooling mode, the engine needs to drive the compressor, which consumes a portion of the engine's power. The car's air conditioning is an important comfort feature. 2. During cooling, the compressor clutch engages, causing the engine to drive the compressor. 3. The compressor continuously compresses the refrigerant and delivers it to the evaporator. The refrigerant expands and absorbs heat inside the evaporator, cooling it down. 4. The cooled evaporator then cools the air blown by the blower, allowing the AC vents to blow cold air.
