Since I started giving lectures about cooling products and a/c, this would be our fifth talk. I have worked in the industry for some time now and like interacting with Heating, Ventilation as well as A/Cs… The ever-evolving cooling tech is a drive of mine in this industry. I am an entrepreneur and have built our a/c company to become the big it is today. The two of us have a program in the supplier where a/c experts help the community by having talks where they answer every question concerning a/c install the property owners might have. The program had tied up myself and others to supply an address for the modern Heating, Ventilation as well as A/C units in the market. I prepared for the talk as best as I could, but when the day finally came, the hall was packed. I was constantly nervous and nervous before a speech. They call it phase fright… However, when I started talking, the fear disappeared as it constantly did. I listed and explained to the newcomers in the market and then opened the floor for questions! During these talks, there are some questions I have come to expect, including central a/c units and how to choose a quality a/c unit. The first question was related to how frequently we should do an a/c device tune-up… Air conditioning maintenance depends on the type of system, however generally, maintenance should occur once a year, and timely a/c repairs. The students, some of whom would eventually become cooling workmen, also had a back-and-forth on how frequently to replace air filters. It was one of the most lively crowds I have talked with regarding indoor air cleaning systems.
