It sure feels awful to be sick. For one, I’m not a fan of having to lay around with no energy and deal with the symptoms. I also don’t like missing days working inside the zone controlled Heating & Air Conditioning of my office either. Even when I’m forced to stay down inside the central AC of my home when I’m sick, I still try to get some work done. So when I get something that stays longer, that’s when I head to the hospital to see a doctor. During the last several years, it’s like several times a year I shall get a cold that lasts for a few days. However, the respiratory effects last longer. I shall have a cough that I just cannot get rid of or something to that effect, and that is what happened earlier this fall. I woke up feeling awful so I made sure I got tested for covid and it came back negative. So I stayed down inside the central AC of my house for 2 days before I felt like I could go back to the commercial Heating & Air Conditioning of the office. Even when I was back to work, I just did not feel like myself and was always dealing with sinus congestion and coughing. I had to go to the hospital. My doctor thought most of my problems had to do with the indoor air pollen levels of my home. So, she proposed the first thing I should do is get the ductwork cleaning done. She also proposed that once the ductwork cleaning was done that I change my cheap Heating & Air Conditioning air filter and add a HEPA filter. I did just that and my respiratory symptoms vanished.
