Are the fresh air intake and exhaust connected to the furnace via the two plastic pipe? Is there an additional fresh air inlet?
Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"
You need to get someone with an accurate CO test instrument to check for ppm (parts per million) of CO in the home. Most co detectors are not sensitive enough to detect dangerous co levels until about 2 seconds before you pass out or never detect it at all
Thanks for the input. The HVAC gentleman is coming back tomorrow. I mentioned that to him the other day, and he informed me that "the fresh air intake is only for the flame and should not matter that it is near the exhaust."
Brand new house, zero signs of mold. All of our symptoms point to some sort of gas or VOC.
Yes, the exhaust and fresh air intake are 2 plastice pipes. I will attach a photo. Also, I am attaching a photo of part of our roof. I assume the "white" pipe is our fresh air inlet??? To the right of that are the static dryer vent, exhaust fan and sewer stack,(which they just raised to over 3 feet.)

Reason: Forgot photos
Everyone should have this type of co detector http://www.climatebydesign.com/co but most have the home depot model that alarms after 70ppm for 4 hours is detected and most of them are installed in a manner that allows "fresh" air to affect them through leaks in wall or receptacle cover and they don't accurately read the ppm in the home
Thanks for the information jtrammel.
Would a good HVAC professional have something like this as part of their tool-kit?
Also, do you know roughly how much they cost, and could I just rent one somewhere?
My suggestion is if you don't have your hvac guy check for CO with a proper
CO detector. Or he doesn't want to do it, or do it properly then I would call your local gas utility or/and your local fire department. They usually don't have a charge for it.
Explain to them when the gas furnace is running you are getting the following symptoms.... and insist that either one of them check it. Course the fire dept will come arunnin usually with light and sirens
This needs to be addressed even if it means it isn't CO (Carbon Monoxide)
