Learning how to deal with your limitations is just as important as maximizing your strengths. That’s true in just about every facet of life. But it’s not always an easy thing to do, and it’s hard to see, accept and adapt to your limitations if you can’t see them. Clearly, when it came to the HVAC unit, I wasn’t paying attention to the reality of our limitations. I’ve been interested in machines since I was little. I’d take broken stuff and slip out of the central air conditioner to the basement where I had a sort of workbench. There, I would carefully dismantle the broken item in order to understand how it went together. I followed that passion and am now working as an engineer, while I have a lot of training and enjoyable mechanical understanding, I have our limitations. For one, I’m not a trained, licensed and certified HVAC professional and I know this. But when I came home to find a heat pump running, but no cooling coming from the HVAC ducts, I decided to solve the problem. And that’s the way I come at things. Yet, I also know that you simply can’t solve problems without the regular tools. I absolutely didn’t have the regular training or actual tools to diagnose and fix the residential HVAC, still, I persisted until I ended up shutting down the entire HVAC unit. That’s when I finally called the HVAC company for assistance. And that’s when I found out that my messing around had voided the warranty on our HVAC equipment.
