I am not one of those people who throws something in the garbage just because it is old. I usually try to find another purpose for it or hang on to it for a variety of other reasons. The only thing that can be tricky with this logic is if the item is rather large and takes up a ton of space. For example, I currently have six classic cars sitting behind my house. Four of them are in good shape but the others don’t even run. I can’t bring myself to get rid of them, though, because I remember how great they used to run back in the day. I hate having to make tough decisions like that. I’m going through a similar thing inside my house as well. I have a really old heater and air conditioner currently chugging away in my basement. They have been in my house since I built it almost thirty years ago. They have been fantastic systems to own up until the last five years or so. It seems as if I have an HVAC technician in my house twice per year now dealing with small repairs. I don’t think I can keep using them, but part of me wants to hold on to them. However, the biggest problem with my aging HVAC equipment is the safety hazards they now have. If my heater ever cracks, I am going to be dealing with a major carbon monoxide leak. I don’t want to mess with that. I should replace both units fairly soon.
