Besides hurting gas mileage, does using A/C in a car having any other harmful effects?

In other words, does using the A/C in a car hurt any of the engine, trasnmission, or other components of the car?

Actually the difference between running the a\c and the drag produced by having your windows down or even open slightly is not noticeable on gas consumption. Not running the A\C can cause the seals in the compressor to leak therefore introducing a greenhouse gas to the atmosphere. Might as well use it, and run it every few weeks in the winter for a minute to keep the seals lubricated.
Reply:No other harmful effects. In fact using the a/c keeps the a/c system in top shape because it keeps the internal parts lubricated.
Reply:As with anything, the A/C system will eventually develop a leak. With R134a refrigerant, the ozone layer is not harmed but it's twice as bad as carbon dioxide for global warming. If you already have A/C in your car, might as well use it.
Reply:nope..it will add stress to the engine, but it was designed for it...
Reply:As long as the engine has the horsepower to run the A/C, and modern cars are certainly designed to do so in general, then there's no reason not to enjoy the A/C you paid for when you bought the car, especially before it fails eventually and is not worth repairing after 10 years or so. However, if it wasn't for my wife, I wouldn't need A/C most of the time because I like to roll the windows down and let nature cool me naturally. I never repair the A/C on a 10 year old car unless it only needs minor work.
Reply:The A/C adds some slight additional load to the engine both through the electrical system and the hp necessary to turn the active compressor. That being said, to my knowledge it doesn't hurt anything or shorten the life of any of the components to run the A/C, except maybe the switches from turning it on and off ;).
Reply:No, and it doesn't hurt your gas mileage much at all. Not running it at all actually good be worse cause the compressor could freeze up and lock down and burn the belts off. So I would run it at least every so often to make sure its charged and running smoothly.
