Stupid question about the AC

[Fat Tony]

I was always told to kill the AC before you turn off the ignition. So ever since I was a kid, I kill the AC then turn off the key and never start the engine with the AC on.

Does this make sense? My grandfather told me this and now i am telling me kid and then I thought about it, is this true? Can anything happen?

I got in the car with the old man and told him it was BS then he told me, "Never once did my AC go out on me! NEVAR!?" Kind of hard to argue considering his first car was a brontosaurus.

So, can I kill the ignition with the AC on?

I've heard this too. And I follow it to this day. Not sure if it's bologna or not...

I shut mine off every time. Never been told to, I just don't like jumping in to start the truck in the morning with all the juice going places I don't need it. I just rather have all the volts for all the stuff it takes to start these motors.

It's not gonna hurt you A/C system, but it may draw down you batt. more on start up. Thats the only benifit I can think of.

I installed a remote start alarm and the module for the AC was two hundred. The guy told me "We're in Houston, just leave the AC on and when you start the car the AC will be on. Saved two hundred." I always turned it off but now, I'm thinking what harm can be done?

It was 110 degrees at 5PM yesterday. That remote start (with the AC on) really helped a lot when I seen the temp guage on the remote saying it was 118 in the car. Then when it reached 92 I went in.

At least for the next 120 days of summer we have here in Houston I am going to leave the AC on.

It's not going to hurt anything. The compressor clutch will disengage while cranking and only once you reach a certain RPM (>500RPM) it will engage.
