Chances are you may be low on charge. The easiest way to find this out is feel the larger refrigerant line (covered with black foam insulation). It should be about 50 or 55 degrees. I'm guessing yours is not cool at all usually pointing to a low charge. This would meant that you have a leak that needs to be found and repaired and the sysem recharged. If it is the newer refrigerant r410a, ou need to pull out all the refrigerant and put all new in. It has multiple compounds and they may have leaked out at different rates. If it is r-22 you can just add what you need. good luck, let me know if you need anything else.

Need more info. Does it cool at all? Is there any water coming out of the condensate drain pipe? Does the larger tube at the outside unit feel cool or sweating? Is the small tube outside warm at all. Is there any heat blowing off the outside unit?
I would change the air filter.
I would remove any slime from the coils.
I would check the attic ventilator(where applicable)
Leave the unit set at 70. Don't shut it down during the day when you are away.
I would oil the motors. All of this you can do without being certifyable. LOL
