My dad had a saying that he adopted from a popular song: “If you’re gonna be dumb, you gotta be tough.” In other words, if you’re someone who doesn’t learn from observation, you’ll definitely have to be strenuous enough to take the pain that comes with first-hand experience. To put it nicely, our brother is one of the toughest people I know! While I knew that putting our hand in a tepid pan on the stove was a exhausting idea, our brother had to know the pain to understand why it was such a exhausting idea! This trait carried over well into our adulthood too, as our brother would make bad decisions that caused personal injury many times. One such opening came when our brother tried to refill the refrigerant for his outdoor air conditioner unit! Just to be clear, only a licensed heating, ventilation and air conditioner repair specialist has permission on a federal level to handle refrigerant for an cooling system. My brother is definitely not a licensed HVAC specialist, however that didn’t stop him! He told me about this incident, where he took refrigerant intended for use in a vehicle’s a/c method – and attempted to recharge his outdoor a/c component with it! While he successfully found the line for the refrigerant and managed to get a can’s worth of coolant into the system, it wasn’t the correct formulation to be used in a home’s a/c system. That meant that he caused his entire a/c method to become seriously disfigured from the inside out, and in turn he had to pay many thousand dollars for a brand up-to-date outdoor a/c unit. Though he didn’t physically harm himself on this occasion, he definitely hurt his financial sitting for the next year!
