Do cars lose power with AC on?
Your car has just under 150 horse power, the a/c compressor puts load on the engine when it is switched on. A lot of cars disable the compressor momentarily on hard acceleration so as to reduce the power loss and let you get horsepower when you need it.
Does turning off the AC give you more power?
RAY: Yes it does, and no you won’t. It does provide a power boost, and it does not harm the car.
Does AC lose horsepower?

Why does AC use so much power?
Dirty coils and dirty filters make the air conditioner work harder and consume more energy and can cause your energy bills to skyrocket as a result. Another reason the air conditioner is drawing in more power could be due to age. Older air conditioning units and systems are much less efficient than newer models.
