I set my thermostat at 72 but it never reaches 79, it constantly runs till late at night. I live in a mobile home and have a outside condensing unit, I was told it might be the thermostat, I appreciate any help.

What do you mean smart ass, that was the next step to check the delta t in your return and supply vents and report back as to what are or were the temps. -:

Mark1368, Heatseeker and theduke are correct in asking these questions as they are trying to determine the cause of your problem.
Not sure if you know but the delta T is the temperature difference between the supply and return air. The air temperature going in and out of your AC unit.
The best way to check this is to have a thermometer with a probe to stick into the air stream. Not everyone has one of these. You can also use a small house thermometer and measure the temperature at the return vent and the supply vent not the best but will work in a pinch.

Check this out and let us know.

Theduke and heatseeker are smart dudes.
