Being sick plus blaming it on the Heating plus A/C system

She said that the air filter was cake packed full of dust plus that the ductwork system was filled as well

I legitimately hate being sick. I tend to blame my friends or family members who were sick before me that they were the ones that got me sick, however this time I personally know it was my Heating plus A/C system that kept getting me sick. This winter time I have been sick at least five times in the matter of three months. That is a record high for me plus something that I do not know is normal. Personally I know that the air filter on my Heating plus A/C system was so dirty, that it was collecting a lot of contaminants plus dust has led to all of my sickness. When I was home sick from work I decided to call my Heating plus A/C serviceman to see if she could disinfect my Heating plus A/C system. When she went downstairs to take a look at it she came back up to tell me that she doesn’t know my Heating plus A/C system has ever been cleaned. I rent the house that I’m living in plus I know I am going to mention to my apartment owner that she should have it cleaned every year before a new occupant comes in. She said that the air filter was cake packed full of dust plus that the ductwork system was filled as well. My Heating plus A/C serviceman told me that he’s never seen an Heating plus A/C system this dirty before in all of the Heating plus A/C systems that he’s repaird on. My Heating plus A/C serviceman also told me that there has no scientific correlation that a dirty Heating plus A/C system makes a woman sick; But it makes sense that if a woman has awful flu symptoms, their flu symptoms may become worse because of the dirty air that is being transfered from dirty ductwork that contains dander, pet hair, contaminants plus dust.
