I am not a home inspector and do not have a CO meter. I was at a customers house and noticed that at the top of the door to the basement that it was dirty as if air was being pulled through the gap. When the blower was turned on the door would be sucked closed.
The top of the water heater had a rust colored coating but it did not appear rusted. In the basement I found 2 sections of return duct panning that were missing thus the return was being pulled from the basement. In 5 of the 7 returns screens had been installed at the floor level opening. In the basement I pulled the panning and found that there was screening at the basement ceiling level for the 4 2nd floor returns. 3 of the 4 2nd floor returns had the screens at both the 2nd floor and basement level.
This home has a heat pump and a gas furnace. This was a cold winter and the furnace would have ran much more than in previous years. Would a furnace with a fan assisted vent have prevented back drafting of the furnace? This is not a 90+ with the PVC piping.
The owner said that the CO alarms have never gone off and no one has experienced flu like symptoms.
All of the screens were removed and the duct panning was corrected. It did reduce the door being pulled closed but did not eliminate it. I went over the seriousness of the situation with the owner and he should have it tested by the HVAC tech but he was not concerned.
