It would seem that I’m one of those people who must learn through experience, rather than observation. While all three of my older siblings made the exact same mistake at certain times in their life, I was practically destined to make the same mistakes. I had to go through the trouble to learn why it was trouble, as stupid as that sounds! Well, I wish I could say I outgrew this learning approach, but even today I can’t seem to trust anyone’s word – let alone my HVAC tech’s word. Months ago, my HVAC technician came by to perform a semi-annual check-up on the heating and air conditioning systems at my house. During his visit, he told me that the air filter he took out of the duct clearly hadn’t been replaced since he was last there. “You have to replace these air filters”, my technician scolded, “or else your A/C system is going to break down – either from all the dirt getting into it, or all the extra work it has to do!” I took his warning with a grain of salt, and almost immediately forgot about his warning. Well, I wish I listened – I had to call my technician over to repair my A/C system, and I couldn’t put my finger on the cause for repairs until I checked the air filter again. The HVAC technician was not happy with me when he saw this happened due to my negligence. “Well”, he said, “some of us just have to learn the hard way, don’t we?” Since I had to endure two weeks of summer weather without air conditioning to cool me down, I’d say I definitely learned my lesson!
