I made this nice and easy code that raises or lowers units based on a timer.
You set the height which the unit will stop moving/die (you choose if he dies based on a boolean) and what speed he moves at.
Here is the code with more explenations inside it
Example raising units and killing them when they get to the max height you want
Example lowering units and not killingthem when they get to the max (min) height you want
I will say it again, please notice that the lowering/raising is based on the unit's current height which means that if you give him a value higher then his height - he will be flying up, if you give him a lower value then his height, he will descend down.

JASS:
//****************************************************************************************
// Move unit's height with timers
// call goingdown(whichUnit,speed,deadheight,kill)

// Warning ! The dead height CANNOT BE 0 ! (I think this is a bug in warcraft)
// If you want your units to die/stop on the ground, make the deadheight=1
//
// If you want the unit to go up, its height should be -lower- then the deadheight and vice versa.
//
// Remember: to calculate speed per second, do your speed value * 50 !
