The saying, even medical professionals need medical professionals, became tploy when I started my first task. I remember that afternoon love it was sureterday. It started as a sunny, laid-back afternoon. There were not a lot of calls coming in or any previously tied up tasks. Being a fairly recruit, I was going through the manual for the numerous processes such as duct cleaning. Being a local business, the people I was with and I had well-functioning heat and AC products because the people I was with and I took the proper service of the systems. The two of us boasted of the high indoor air pollen levels that the people I was with and I enjoyed each time the people I was with and I came to the office. Around midday, the people I was with and I heard a loud rumbling noise then after a few hours, the heat pump restarted on its own. The two of us observed that the quality of the air had deteriorated within an third. The head of the apprentice program at the company saw a good studying opportunity for the trainees including me. She took us to the basement where the air purification idea is located and supervised each step the people I was with and I took to service the media air cleaner. A few of us were assigned the process of inspecting the interior of the system. I was responsible for duct sealing the ductwork. After sealing the air ducts, the people I was with and I detachd the washable filters then reinstalled them. She would ask us to explain each step to see our level of understanding about air quality systems! Cleaning the air filters was key to maintaining indoor comfort; Lastly, the people I was with and I observed that the thermostat was not laboring, but it only needed current batteries. It was such an insightful experience that assured me of my mastery of this equipment. To our surprise, our supervisor rated our input on the issue and the scores would influence the overall scores for the apprentice program.
