I wonder how the Heating and A/C guy knows that the heating and cooling plan is done for? I mean, it’s a machine, so the parts are updateable… Maybe it is just that there comes a time when it would cost more to maintenance than to just get a modern Heating and A/C plan all together. I should ask my heating, ventilation, and air conditioning repairman next time he’s out at my house. I’m just curious. I’ll need to have him back pretty soon anyway. I just ordered a updatement Heating and A/C plan that, once it comes in, he’s going to be installing. It is a recent development, so I assume I just have that method on my mind, while he was telling myself and others about the fact that I needed a modern heating and cooling unit, I was mostly just trying to crunch numbers in my head. After I had some time to think about it, though, my brain sort of went off on a tangent. Where do Heating and A/C systems go to die? Maybe someone scraps the metal? Does anyone ever decide to keep their old Heating and A/C plan and just have all the parts updated? I mean, it sounds deranged, however I can imagine people being weirdly sentimental about things… I don’t think I would really ask my heating and cooling professional all of these questions. He doesn’t really like to chat, which is great with myself and others really. I don’t want to bombard him with questions while he’s trying to work. I’m just really curious now. Actually, I bet I could look up the answers online and save my air for something more important.
