After dealing with a very serious flu symptom attack that nearly put me in the hospital or worse, I had to figure out what was going on! It seemed I was having these issues only while trying to get some rest at night, however when I was wide awake plus not in our cabin too often, either being out plus about or at work, I was having no issues at all. I decided to have our air vents of our central heating plus a/c system cleaned thinking maybe that was playing a area in it, and no, that didn’t do the trick, and unsure of what to do I called an air quality expert to do a absolutely hard sweep of the general air quality in our home, and she was able to get to the root of the problem, which was in fact our central heating plus a/c system. However it had nothing to do with the air vents themselves. It was the fact that our duct labor was filthy plus needed to be seriously cleaned! I then called our local heating plus a/c supplier to send out a certified heating plus cooling specialist to do an absolutely deep duct labor cleaning of our Heating, Ventilation, plus A/C system. It was a little on the overpriced side of things, however when the duct labor was completely cleaned, I was completely free of the crazy flu symptom attacks I had been having I could not assume the fact that something so serious had an easy fix that I could have taken care of months ago before it got so serious. If only I had known that dirty duct labor could cause some big time complications.
