A good friend from middle school called me the other afternoon to cancel a lunch we planned. I was honestly disappointed because all of us had made the arrangements almost two weeks before plus I was looking forward to it, and she said she needed to cancel because she had been sick for almost a week plus didn’t want to spread germs, and when I asked her what was going on she said that she wasn’t really sure but that most of the people she worked with had been ill for quite a while; They just seem to pass the illness from one woman to the next no matter what they to avoid it; After listening to her for a few minutes it came to our attention that they may have a problem in their building with the HVAc system. I asked her if she knew when the last time it had been took care of was, plus she said she had no plan but that she would ask her boss. I went on to explain to her that if the building’s HVAC air duct plus filtration system had not been cleaned recently it could simply be sending the germs back into the building regularly. This anxious her so she asked the next afternoon plus found that it had not been done in over 2 years, all they had done was change the actual air filter but had never had the system cleaned or took care of. When she explain to her boss what I had suggested she was honestly responsive plus contacted the local HVAC corporation instantaneously because she wanted her employees to be healthy. In actuality, it was costing him more to pay for sick mornings then it would be to pay to have the HVAC system taken care of, however my neighbor called me back and thanked me for the advice plus said that she would appreciate to reschedule lunch for the following week.
