When you say that "you should carry the computer to install in the house," does it mean you have to carry it into the house and also install it, or that you only need to carry it into the house for it to be installed by someone else?
I would appreciate your kind help.
It's not a very good sentence. Without more context, I can't see why they use 'carry'. Given that it is a house, it follows that the person will install it. If the shop is going to install it, then why dos the buyer have to carry it?
