I have only been in my living room for about an hour and when I went in the second half of my house I came across a strong turpentine smell, I haven't had any painting done at all not even recently and there was no turpentine smell before. No lights were on where the smell is and the heating hasn't been on either, there is a boiler in my room I do smell it in there as well but I don't know what it could be.
