Your A/C should run only half time as most are not designed for 100% duty cycles, a leak in the a/c lines, or a poorly installed a/c system would tend to cause it to run full time.
It also sounds like large house that has issues, if it was built in the or 90's then that is most likely the case as so many short cuts were taken that it might be cheaper just to move on, or burn it down.
but really, to spend your money wisely you might be best off getting an energy audit done, $300 and you will find the issues.
