Last summer, I kept getting sick plus I could not figure out why, and first, it was my youngsters plus then it was me. I figured that it was just a virus that the youngsters picked up at school plus brought home… Like any other time my buddy and I got sick, I sanitized the entire household from top to bottom; Sporadically, it takes more than a household scrubbing to get those germs out of the house. I noticed that there was an unusual smell in the air coming from the air vents one evening. I was starting to feel sick again, plus I was not sure if I had picked up that bug again. I did a little more inspection of the air vents. I noticed that there was a little bit of mold on the outside of the vents. Then, I climbed into the ceiling to check out the HVAC ducts. They were covered in mold. I was horrified. I called the Heating & A/C company as suddenly as I could get out of the ceiling. I explained that I had been legitimately sick a few times back to back plus they said that it was likely that I became ill from the mold in the HVAC ducts. I was so grossed out. I asked them when they could have someone come plus scrub out the entire Heating & A/C system. They had someone out the following day. After the Heating & A/C was thoroughly cleaned, I had no more concerns with being sick. It is important for people who are getting sick over plus over again to check their homes for mold. It can be hiding in the most unsuspecting locales, like the air vents.
