My kids and I just moved down here. First Florida summer... I lost my job (babysitting problems) ... and the house I just bought, AC is leaking freon. The guy that came out said to just buy a new air conditioner. I can't do that. Anyone know anything about how to stop a leak and add freon? Or who to call that won't charge me much? We're dying here...it's hotter inside than it is outside. Thanks in advance.
