Does AC affect engine performance?
Because the system is powered by your engine, using AC will pull energy from it, which can affect engine performance. When the compressor kicks on, your car’s engine RPMs may increase. The power used by the air conditioning system is offset by this.
Why does my car go slow when I have the AC on?
The compressor requires 5–10 horsepower to pump the fluid. Say your car has 100 horsepower to get you down the road, when the AC turns on the compressor uses 5–10 horsepower and now your car effectively has less horsepower to get you down the road, which is why you slow down.

You’ll also find that the power drawn from the engine has a more noticeable impact with smaller engines.
