We headed to a customer’s house one morning to do some air conditioning repairs. I had a team of five cooling specialists with me. Some were novice training, while the rest had experience working on cooling equipment. The customer had called the air conditioning business complaining that his heat pump had been acting up for a week. He explained that he had noticed decreased indoor air quality and comfort. The air conditioning unit was also making unusual noises. When we got there and assessed the system, we found that one major part was broken. The unit was quite old and would have soon been replaced. As the senior air conditioning expert, I recommended that the customer consider replacing the system. The customer was fortunate to purchase the new unit on sale from the provider of the cooling product. One of the junior a/c reps in my team came to me with a concern that he was not comfortable assisting with the air conditioning installation since he was conversant with the new cooling technology. I asked him to watch keenly while the rest of us executed the process. We then advised the customer on the importance and frequency of scheduling air conditioning tune-ups. That incident with my junior got me thinking of creating a new installation manual incorporating the new tech. The trainees would use the manual to learn more about air conditioning. The manual would include the installation process of the common parts of a cooling system, including air conditioning filters. Technology is constantly evolving and changing, and we must keep up with it.
