Check to see if your outside unit is running. If not, check the breaker. If it is running you may have an issue with the reversing valve. It looks like three lines coming out of the top and one on the bottom. Trace the wires back to see that they are tight and secure. Of course, TURN OFF THE POWER first. good luck.

There could be a freon leak, or just low freon levels. If this is the case, you have to call a certified a/c technician to recharge your system.

You should have the manual for this unit handy and as far as recharging tools go. You only need a can of R134a *(if the unit is R12 you need to buy upgrade adapters since R12 is no longer sold) Run the unit and put the R134a filler line on the low pressure side of the compressor *(from manual...dont guess as trying to charge the high pressure side is VERY dangerous). Get the charge just into the Green zone on your charger and that is it! Try not to fill too high in the green zone....I know it sounds funny...but AC's usually work better when they have the low end of their optimum fill. R134a doesnt work as well as R12 so be sure you buy the R134a with cooling enhancers. Your local Autozone can guide you to the right filler/product combination.
Good luck and be careful!
