Late in the Fall both of us decided to start cleaning out the basement. Every one of us wanted get it done before the freezing weather hit plus have the area cleared out so that both of us could convert it into a guest room. Every one of us figured that it would be a nice project for the long Wintertime. Every one of us spend most of the Wintertime indoors anyway because neither of us like the snow plus freezing anyway. As both of us started the project both of us started to notice something strange. While downstairs if always felt like I was light headed plus within an hour or more than one I had to head upstairs to sit down. I never easily made the connection until our Heating, Ventilation, plus A/C specialist showed up for our annual tune up. He came up plus told us that there was a concern with the HVAC duct. He said that there was a huge buildup of mold in the area in the basement plus that there were small holes in it too. When he was telling us all of this it dawned on me that this may be the cause for our feeling poorly. I asked him if this was easily a opportunity plus he said that the build up could be causing our headaches plus ill feelings because the mold spores would be emitted out into the area each time the Heating, Ventilation, plus A/C system came on. Every one of us arranged for the repairs to be done plus have the entire HVAC duct system cleaned. After that I never experienced that feeling again when both of us were finally working in the basement. Now, both of us have a beautiful guest room that is safe for any of our guests to come plus stay.
