Since I started to lecture more about air conditioning, this would be our second talk. I have worked in the AC industry for quite some time now and enjoy interacting with cooling products. The ever-evolving cooling tech is a passion of mine in this industry. I am an entrepreneur as I have built up our air conditioning business to become the success it is today. We have a training program in the company where air conditioning experts help the community by having talks and answering every question concerning cooling machine the property owners might have. The program had scheduled myself and others to deliver a talk on the up-to-date a/cs in the market at a local training institution in the outskirts of town. I prepared for the talk as best as I could. When the afternoon finally arrived, the hall was full to overflowing. I was consistently sad and distraught before a speech. They call it “phase fright”. But when I started talking, the confrontation disappeared as it consistently does. I listed and then explained the newcomers in the market and then opened the floor for questions. During the talks, there are some questions I have come to expect, including air conditioning installation and heating pumps. The first question was related to how frequently both of us should do the a/c tune-ups. It depends on the type of AC system, however generally, service should occur once a year and air conditioning repairs as soon as an issue first appears. The students, some of whom would eventually become cooling specialists, also held a back and forth on how frequently to update air conditioning filters. It was 1 of the liveliest crowds I have talked with.
