2006 Kia Optima Q&A

2006 Kia Optima Question: My car only blows hot air and there is a wheezing noise when the fan is on.

My air conditioner has gradually lost it's cool over the past couple of weeks. It now only blows hot air and there is a definite loud humming/wheezing sound when the fan is turned on. It goes away once I turn off the fan. I want to sound half way knowledgeable when I take it into the shop so that I don't get charged an arm and a leg. Does this problem sound like one you've experienced before? -
