I do not usually watch this show, but as flipping by it the words air conditioner man were heard.

Obviously backwoods as the guy does not even have a 1/4" nut driver, but as he crawls up onto the deck inside the shop to the horizontal gas furnace, there it is plain as day;

yellow gas flex and two of them coupled together I think, coming off the deck area and into the cabinet.

now there is a thread on here that shows the dangers of this.
