I can always tell the difference when someone is actually passionate about what they are doing, versus someone who clearly only sees it as a means to get by.
A good example is I recently had my carpet cleaned.
Two different guys came out to tackle the carpet in my home, and I was casually observing them both. The difference between this was astounding. On one hand, I had one guy practically racing to get done, skipping many different spots while he was at it. On the other hand, the other guy was taking his sweet time, making sure to go over any stains and spot check as well. I could tell the second guy cared about his job, the first guy just wanted to be done. I have also noticed this between heating and A/C workers. The first HVAC business I called sent out a HVAC tech who couldn’t have been more bored even if he tried. He brushed off many of my questions and seemed to look in any other direction except my central A/C. I honestly wonder how he got any work done. Then the second guy was an independent A/C contractor. This guy I could tell loved what he was doing. He not only spent a good 10 minutes explaining the entire process of HVAC maintenance and tune ups, but also was very thorough and careful when examining my air conditioner and furnace system. The difference was clear as day, and I definitely appreciate the ones who care. It is those people that I will be going back to.
