When the roofers tore off our roof, the furnace in our attic and the attic did not get covered properly. Point being there was 100 year old shingles (2 layers of wood shake and 3 layers of asphalt), wood , dust and who knows what else and what kind of shingles they were. When the debris was cleaned out by my husband he looked black as night from the asphalt dust.When I turned on our ac , a horrible smell came through the vents and we had to turn it off and air out the upstairs. Since then, we have had it on and off only when necessary and for short periods due to the smell, but we all sleep upstairs and its about 83 with the ac off.
I am the only one in my family with allergies and my throat is burning, nausea and sinus issues.Now one of my older kids is sick and saying their throat burns when the vent above the bed comes on. I have a smaller child getting sinus problems and feeling sick.
More info that may help:
The upstairs ac/furnace is mounted to the attic floor and return air vent is in the hallway ceiling. It is an unfinished attic with fiberglass insulation between the joists.
My house was built in 1902 . We have 2 units for heating/cooling. One upstairs and 1 down.
Originally, there were no vents on the roof, only a louvered vent on the side of the attic wall.
The roofer installed 6 small vents on the roof for ventilation and the only appliance that runs on gas is my downstairs furnace which is vented directly through the basement wall.
Any help would be appreciated. Thankyou
