...of my vents in my house am i safe? ok so there is 2 vents that sorta have a gas smell. i have opened all my windows. my mom was an idiot and light the stove and nothing happend thank god. i dont think it is carbon mono because no one is feeling light headed. the smell is not always there. the vents are near the bathroom. i thoguht it was from my ac which is off and i checked the fan outside for my ac and it smells fine. i checked my vents outside there fine. oh idk if this will help but we had pretty bad rain a couple of hours ago. btw i am not sleeping because i dont wanna risk death
