What happens if you start your car with the AC on?
It’s not harmful at all, Stanley. For two reasons. First, cars automatically shut off auxiliary power while the car is cranking. So when you turn the key to crank the engine and start the car, the AC, the radio and virtually every other electrical device is shut off anyway.
Is it bad to turn on AC while engine is off?
You cannot run the AC without the engine running. The air conditioner compressor and clutch are operated by the serpentine belt that runs your other accessories (your alternator, for instance). That means your air conditioner’s not actually on. You cannot use the air conditioner if the engine is not running.
Can your AC drain your car battery?
If you run the AC when the car is off, it not only puts a strain on the battery, it can completely drain it. Now, if the car is running, and barring no issues ( bad alternator etc), it puts a load on the battery, but the alternator is able to keep up with the demand.
Can you sleep in a car with AC on?

How do I run my AC with the engine off?
3 Answers. In a normal car, there is no way to run the A/C without running the car. To make the A/C work, it requires a compressor to act on the refrigerant, and the compress runs off of the engine, not the battery. Even with a spare battery, this would not work.

How does a car start when the battery is dead?
The battery sends it a jolt of electricity, which the starter uses to turn the engine over and get it to start. A broken starter will make a clicking sound when you turn the key. The car won’t start, but the dash lights are on. Jump starting your car or truck does not turn over the engine at all.
Why does my car not start after I jump start it?
If jump starting gets your engine started and running, but the car will not start again once you turn it off, the battery is probably the problem. In this case, the alternator is doing its job of keeping the battery going once it has been jumped, but the battery can’t hold a charge when the alternator is shut off.
