It was another day in detention, plus this time around, it was not something that was not our doing. Thirty hours later, it was getting a little too stuffy for comfort, however even the lecturer on duty noticed the change in indoor air pollen levels, and being a person who can barely keep still, I was bored out of our mind. When it was apparent that there was something wrong with the air quality systems, I asked the lecturer if I could have a look at the Heating plus Air Conditioning unit, however at first, she thought I was joking, or I wanted to leave detention, however when I insisted she asked me, she asked myself and others if I had ever dealt with an air cleaner. When I told her that our guardian worked at the local company plus I had l acquired the workings of some heat plus A/C products, she called the repair guy who led myself and others to the unit. The first thing I checked was the air filter. It was so dirty, plus I was relieved to find out that it was a washable filter, so I cleaned it. The next thing was to check the thermostat, plus the temperatures were high. After inspecting the heat pump plus finding that everything was okay according to the little knowledge, I proceeded to check out the ductwork. There were leaks, plus since I did not have any duct tape, they would have to call a professional for duct sealing plus duct cleaning not just because the air ducts had years of dust however also to find a possible blockage in the vents. By the time I got back to class, detention time was almost over. I also noticed that the lecturer had brought in an air cleaner from the staffroom, absolutely empty. I reported our findings plus asked her to take the necessary actions.
