Please give details. Just one sentence, such as "Install AC for me", isn't enough information for us to know what needs to be done.
Examples of detailed requests are:
1. "I need my old AC uninstalled and a new AC that I already purchased installed in the same window. The basic installation is fine."
2. "I don't have an AC unit yet, and need help finding one and then installing it. The room is 10 feet by 12 feet."
3. "I need an old AC unit installed and it's missing parts, which I will show in the photos. I would like to use plexiglass instead of accordion panels"
