My family came from hardknock roots, and regularly found a way to make it work.
My people were farmers, they were often scavengers, they were hunters, they were at times, hustlers or guys of low character! Whatever it took to keep the family chugging along.
The point of all this is that I grew up poor, and l gained hastily how to use exactly what I had at hand. That meant using parts of cars to fix other cars, and even borrowing from one guy to pay off another. The home where the people I was with and I live has the oldest central Heating and A/C method that has been addended and upgraded with various stupid parts and components over the decades. This is a frankenstein’s monster of a central air conditioner, that works sometimes and doesn’t work other times, but under our feet, way down in the cellar lies a monster, is the antique furnace and the equally old water boiler. These damn things have been kept really working with Heating and A/C parts I have taken from other systems and found a way to make them work. It’s a disappointing system over time, I know, however at no point did the people I was with and I have at least a few extra thousand bucks laying around for a new Heating and A/C system, so you know the people I was with and I did the best the people I was with and I could. The most amazing thing to me is that it works at all, however to me, the heating aspect is really pretty reliable. The furnace may be ugly, however it is still undoubtedly powerful.
