My Rheem central heat and air is not working. Most important now is the heat. The heat comes out, but the air blows cold. Before I spend the money for an expensive expert... is there any hope of me fixing it myself... or doing some checks so I have an idea what is wrong to save time and money if the technician has to be called in. I'm pretty handy and can follow directions. I have no owners manual... any idea where I might find one on line. Thanks in advance... Freezing in Fort Lauderdale.

What model, year? Etc , help me help you

That model number is the coil I think, 10 seer, 3 ton, 17" wide coil. Is it a heat pump?

Heat blowing cold on a Rheem RCBA3765AS17. Electric 2.5 ton central heat and air. The air isn't cold either but I know I have a freon leak... the heat was still working. Any ideas of quick checks before calling in the experts. Finances are really tight.
