I need some professional advice. We just moved in (1 month ago) to a brand New construction home. We are experiencing Burning eyes, nose and throat, headaches and dizziness when the Air Conditioning starts running. The builder sent someone out to raise the vent stack on the roof, as they felt it was maybe too close to the fresh air intake. However, after 3 days of "airing" the house out, we decided to test it out and within 10 minutes of the AC running, we started having symptoms. We have a unit in the attic and one in the basement. We seem to get symptoms from both units. When we shut the units off and open the doors and windows, the symptoms subside. I would not expect any of this from a "newly constructed home." Does anyone have an inkling on what they think it could be? Thank you so much in advance.
