electricity from house to garage

Do garage door openers run on 24v ?
I think buying everything that he wants to use in 12v/24v models will cost more then a sub panel

You do know that you are not in code by running Romex through Conduit all the way.

1/2 hp at 24v is >15A. You won't save in the cost of wire, that's for sure.

Maybe 15A and below is a good breakpoint for deciding to go low voltage, rather than 120/240v. That, what loads you have, peak watts and average w-h needed.

The NEC doesn't apply to me, as I'm out of jurisdiction. However, the ground temperature is about 20F for 6 months of the year.
Can you imagine, cutting the Romex installing a box, running separate conductors in the conduit, another splice in a box at the other end!
That's just another rule that was dreamed up to cover somebodies back side.

It is done that way all the time.
