Air draft from basement
Is it normal to have a draft of air coming from your basement to the
main floor? You can feel it easily coming from under the basement door on the main floor level. The Basement windows and doors are closed and when installed were sealed tight with foam. No draft is getting in around them. Yet, the door on my main floor leading to the basement has a fair amount of air draft coming in under the door. What could be causing this? |

What could be causing this? If you realy want to know and not guess get an energy audit and a blower door test, even a blower door test itself will give a printout of how many air exchanges per hour your house has and should have. The tech then pinpoints all the leaks with a smoke stick. Old houses are leakers, the test might pay for itself in a few months, mine did. It might cost 300, a full audit would be a few hundred more but will eliminate guesswork on how to save on utilities. |

Air draft from basement
My Guess....furnace in the basement? Does it happen all the time or only when the ac/furnace blower is running? It's pretty much happening all the time. I do have the HRV running most of the time. But even with that shut off I still feel draft. The basement is about 75% underground with 8' tall cement walls. The rear of the house is above ground and about 10 feet on either side are also semi-above ground. It has to be coming from the HRV or dryer vent. |

If you have Central air, and the return duct is on the main floor, it could be sucking the air out of the basement. If you have a whole house attic fan, it could be causing the same effect. |

How about the chimney for the fireplace, the chimney for the furnace, a demon in the basement sink drain, a demon under the stairs? What is an HRV? *Human resources vector? *Home repair velocipede?

Air draft from basement
check where the drain stack goes through to the upper reaches. See if there
isn't a blast of air coming down from the attic. That's what i found mine doing. They had cut about a 8" square hole for a 3" pipe, and i stuffed it full of fiberglass insulation. s wrote in message ...

@news.astraweb.com: You have ghosts. Wouldn't suprise me. I live next to a graveyard. That might explain all the weird noises I hear in the middle of the night.;- |
