I have a few questions, please. We bought our so called Energy Star Rated, Spray Foamed, Air Tight home in July of 2011. We have been sick constantly non-stop since several months after moving in. We recently had an I.A.Q. test & A.C. evaluation done. The findings are disturbing! We have a fresh air intake vented to the outside that goes into the air handler after the filter. The air is not filtered and what makes it worse is that the vent is located directly over the outdoor a.c./heat pump & over-sized gas pool heater. Next thing that bothers me is that there is no screen or anything keeping birds or anything else out of the vent. Are there any regulations/standards or codes? Could this be affecting our health and the high humidity in the house?
