We had to build our own HVAC units to survive the war.
The world is in a terrible state.
Several nuclear reactions went off, turning most of the world into a desert. This desert heat is so brutal that most do not survive without a central air conditioner or window air conditioner of some kind. Few homes had the luxury of a multi split air conditioner on hand. Times got even harder when the government ordered all families to hand over their central air conditioners, window air conditioners, and hot water boilers for the war effort. The military used the HVAC units for necessary metal. The government also had all the HVAC technicians move to a huge HVCA facility where they would work to take apart all the air conditioners and furnaces to be used elsewhere. The people, women and children mostly, were struggling to survive the brutal waves of heat and cool that came. My sister and I decided to use what our dad taught us about HVAC units to try and build one of our own. We had very little heating and cooling equipment to work with, so most of the air conditioner would have to be made by scratch. We did not even have an HVAC store to go and search for better heating and cooling equipment for sale. We didn’t have much, but we were able to build a crude air conditioning system that worked surprisingly well. In the winter we just resorted to building a big fire in the middle of our home. We had no idea how to make a hot water boiler or an electric furnace that would actually work well.
