A few months ago I started having something unusual happening, my entire face would swell up without reason to the extent that I could barely open my eyes. It looks like I had just been eating shellfish despite a serious allergy. At times, my eyes were really so puffy that I could not see straight. My respiratory health began to fail around the same time. I developed a persistent cough but sporadically turned into a dry heave and a painfully raw throat. It started getting truly tough for me to regulate my health and attend work every afternoon. No matter how several doctors I went to, they couldn’t seem to help me with my immune system and respiratory health concerns. They kept putting me on new allergy medications and sending me back out the door. It wasn’t until my friend saw an article on the downstream effects of terrible indoor air quality that I finally realized my home and central Heating and A/C system were the problem. Living in the South, the air is respectfully warm and humid. This makes your home extremely susceptible to mildew and mold growth if you do not have the regular air quality control devices in locale. Not only do people rely on their central cooling systems to control air temperature, but they serve as a relative humidity management system. Unfortunately, my central cooling system was over 15 years old when I moved in. I knew that the old A/C didn’t do an amazing job with energy efficiency, temperature control, or air quality management. However, when I finally called an Heating and A/C worker and they notified me that there was black mold growing in my ductwork work, I realized the full extent of my Heating and A/C woes. No allergy pill on Earth can undo the disfigurement of black mold in your central heating and cooling system.
