So are you, or maybe someone you know, an “I can do that myself” type of person? Maybe they just need to watch a couple of YouTube videos and then they are a master at everything. I’m sure I know a couple people like that, my brother in law being one of them. You know how some people are too smart for their own good? Well, he’s one of them. He decided to replace his home air conditioning unit in his attic with the help of a neighbor and a close friend. My sister, on the other hand, was totally against this and asked that he call in a professional HVAC company. But his pride wouldn’t hear it and neither would his wallet, so the installation started a week later. There was a lot of yelling, grunting, bruises, and midnight coffee runs, but he was determined to get it done. My sister was still holding onto the hope that he would call an HVAC installer but it really seemed as time went by that was not going to happen. It took about a week for the heating and air conditioning units to be installed, definitely quicker than we expected. My brother in law went over to the thermostat and with a big smile on his face he turned the air conditioner on. It purred and sounded good, was kicking out nice cold air, and within a half an hour the house was cooling down nicely, just like he promised it would be. They went to bed that night, happy thinking about the money they had saved doing their own DIY HVAC installation. However, even though this story turned out on the happy end, please don’t ever think you can take on a project of this magnitude by yourself without consulting an HVAC specialist first!
