Well, whether you NEED AC or not is a matter of opinion. You also have to think of the resale value if you decide to sell it. Mine is disconnected so that if I ever wanted that cluttered mess back in my engine bay I could replace it all. If you work on your own car you'll be glad it's gone. Yes, you can actually see your sparkplugs! Also think of the airflow that condenser is blocking. Sure you can buy a smaller one and get the whole system retrofitted and charged but it's gonna be expensive. More than it's worth to me. But, in today's spoiled world noone will want to buy it without AC.
