I told my uncle it was a terrible idea

I guess I am known for my nice advice, because I commonly have a lot of people call me to ask for advice. This has regularly been surprising to me, because in my opinion, my advice is just meh. Anyways, a single thing that I am nice at giving advice on, is anything Heating and A/C related. This is because I am the only a single who has gone to Heating and A/C school in my entire family. As a result, whenever any of my family members have an issue with their heating system or cooling unit, I am the first person they call, before calling a professional Heating and A/C serviceman. I try to supply advice as best as I can over the PC, but it can be hard sometimes when I am not physically there to inspect their Heating and A/C components; For the most part, even if my advice is not what my family wanted to hear, they still accept it. Except for Uncle George, but uncle George is easily his own character, and he does what he pleases, and that includes ignoring any advice I may supply him. When both of us talked on the PC last time, he told me he had a fantastic idea. His method was he was going to downsize to an older model of a/c unit, because he thought it would save him money. I tried to tell him that that is not how it works at all, and if anything, an older model would cost more money to run, despite the fact that he wanted none of it. Well, I tried, so hopefully that goes well for him.
