How can I add two or more sets of hours:minutes:seconds? For example, if I
add 12hr30min00sec to 1hr45min45sec I should get 14hr15min45sec.

Try formatting the cell which contains the addition formula as
[hh]:mm:ss

YOu can add the values if the cells contain the time values 12:30:00 and
1:45:45, but not if they contain the exact text (with hr, min, and sec
embedded) that you show in your message.

If the times are stored as normal Excel times, they just numbers
(representing a fraction of a 24 hour day, 0.25 = 6:00, 0.5 =
12:00, 0.75 = 18:00, etc), so you can simply add them as you
would with regular numbers, using '+' or SUM. Format the result
cell with a custom number format of [hh]:mm or [hh]:mm:ss .
