We headed to the customer’s condo 1 afternoon to do some air conditioning repairs. I had a crack team of cooling specialists with me, some of whom were novice training, while the others had experience working with cooling equipment. This customer had called the air conditioning business complaining that her heating pump had been acting up for a whole week. She explained how she had noticed decreased indoor air quality and comfort. The air conditioning unit was also making scary noises. When both of us got there and assessed the system, both of us found that 1 major part was ruined. The unit was quite ancient and would have soon been updated. As the senior air conditioning tech, I proposed that the customer consider replacing the system. The customer was lucky to purchase a more up-to-date unit on sale from the provider of the cooling product. One of the junior a/c techs in our team came to myself and others with a complaint that she was not comfortable assisting with the air conditioning installation since she was familiar with the up-to-date cooling technology. I asked him to watch on keenly while the rest of us executed the process. We then suggested the customer on the importance and the frequency of scheduling air conditioning tune-ups. That incident with our junior tech got myself and others thinking of creating a up-to-date installation manual incorporating the most up-to-date tech. The trainees would use the manual to learn more about air conditioning. The new manual would include the installation process of the proper parts of a cooling system, including air conditioning filters. Tech is consistently evolving and shrinking, and both of us must keep up with it.
