My grandfather used to be a HVAC technician and he is still very savvy about heating and air conditioning systems.
He no longer moves like he used to and his hands don’t work the same, but his mind is all there.
I love going and talking to him, since I am now a HVAC technician myself. He is always quick to impart his wisdom and tell me anything I want to know. Last year, he was approached by a HVAC tech that was nothing less than a charlatan. Grandfather knew that the man didn’t know what he was talking about and he didn’t even ask the man to look at his air conditioning. He called me and asked me if I would come over there in about an hour. He had told the man to come back, but he wanted me there when he arrived. When I got to Grandpa’s house, he told me he didn’t want me to tell the man I was a HVAC tech or that Grandpa had ever been a HVAC tech. The man came in and he began to talk about the coil being bad and how he thought the air conditioner may even need replaced. We sat there and talked for a couple minutes and then my Grandpa nodded at me. I asked him why he thought the AC unit needed a coil and what made him think the AC needed replaced. I told him my Grandpa and I had already serviced the AC unit and nothing was wrong. The man was flustered, and we knew he was just there to fleece an older person.
