My uncle is what you might call a bit of a doomsday prepper.
He has been building a crucial bunker underground back in the woods behind his home & he’s pretty drastic about it.
HE has been working on it for almost multiple years now, & he almost has it finished to his particularations. He was really picky about everything that went into the bunker, & that included the HVAC! When I told him that I thought it was peculiar that he was going to have a HVAC down inside the bunker, he went off on a long tangent about how crucial heating & cooling is, especially when you are trying to live under the ground. I guess he’s right about that, although I had never undoubtedly thought about it before. If you are trying to live underground then you undoubtedly need a high quality ventilation system! I don’t guess that a bunker like this a single is undoubtedly all that necessary, however our uncle is sure that the world is going to end in the next few years & so he wants to be ready for it. I don’t guess what he has stored down there in the bunker, although I do guess that the air quality in there is going to be great. He told me that I could live down there with him when the time comes, if it’s necessary. I guess it’s a fantastic thing that he got this fantastic ventilation system put in because two people breathe more air than a single!
