Ok my house is only 1080 square ft. I give up my air set on 75 but when I achieve home in the evening its other about 85 to 90 contained by here. The A/C isnt that old.. Well its just about 8 years old so possibly it is I dunno. I change the filter regularly, I have the coil cleaned out by a professional, they also said everything else was fine. So whats the problem?!
Why won't my rototiller start?

You probably need to hold the freon check. You could have a dribble in the stripe. The freon is what cools the air. But you hold to get a contractor to check it because it's hazardous and could produce damage to the Earths ozone division if released into the environment. You should never have to join freon to your A/C unless you have a escape or the proper amount was never added correctly.
