Is it possible to get cool air when there is zero freon?

What is your question?

My car's air conditioning worked great. I could keep the dial on the first or second tick. However, when it got hotter than 105 degrees outside the air blowing wasn't as cold. When I went in to have it checked at a repair place, they told me it was totally empty of freon. Is it possible to get cold air with no freon? I suspect that they drained the freon. They wanted to charge me a lot of money to repair it and replace the freon. I'd like some other opinions, please. I didn't have them do the work saying I wanted a second price quote. My car blew warm air all the way home. I was drenched with sweat. I strongly suspect they released the freon in the car to hike up the price.
