Hi there! I am experiencing the same issue, and it would be highly appreciated if someone could respond to this question. My air conditioner was broken while I was working on the introduction to my paper, and the master recommended me to check this website au-assignmenthelp.com for more useful writing guidelines. Thanks to this website, I got the highest score for my essay. As for the furnace, I received this issue after the conditioner was repaired and do not know how to deal with it now.
