House Smells Like Hot Attic

This is a combination of lumber insulation shingles all getting cooked in this hot attic air.
House smells like hot attic. The unpleasant odor can also attach itself to items stored in the attic. If you notice this type of odor coming from your attic avoid entering it unless you are wearing a proper respirator. Where those wires punch through to the attic are rarely sealed properly or at all and that is just one more path for hot air to travel down into your house bringing that lovely odor with it. If that s not the problem vacuum and then scrub the firebox the area that contains the fire at the base of the chimney.
There are other holes as well like where the wire from your light switch travels up into the attic. Most likely the smell will be knock you out strong in one particular area and that should be able to help you identify the source whether it s in the attic basement or some specific wall. Chimney smells can be drawn into the house when these are left open. Sniffed the walls the floor outlets ac vents no moldy window sills and it s mostly in the doorway.
On cool days no smell but when the attic gets hot the one bedroom has the smell. I would say eliminate the smell through ventilation. It might be you have a gap or air leak in the returrn air duct that is allowing this smell to get into ductwork. Such odors may even make the items or clothing you re storing in your attic smell as well.
And infiltrate the airr in the duct even though it s not running. What causes that old house smell three things that musty old houses have in common. However attics can also have problems such as a musty mold odor that are normally associated with basements and cellars. Another potential source of attic odor is from a combination of rodent droppings and urine when mice or rats take refuge in the attic they are naturally going to do their business here.
If the smell persists after the firebox has dried following this cleaning call in a chimney sweep to clean and inspect your chimney. The musty mold odor can creep down from your attic and take up residence in other areas of your home.
