Adding repair time on offensive units

They add up.

Your existing add-on expires at the designated time (when it has always been due to expire) and the new extra will expire in 30 days. For a time you get the 18h+48h or whatever extra you use.

So they add up I do not loose the previous 18 hrs already bought?

They add up. Some players have weeks worth of it added up. If you go to your offense, click on the repair icon and up the time will change to how much repair time you have left. Hover over it and a tooltip will show expiry dates for each lot of repair time.
