person A: I just had my air conditioning system cleaned out because it wasn't working right. Wow_comma_ the junk that came out of it was awful. The owner before me never used filters.
person B: Did you call him to complain about that?
person A: No_comma_ since its my house and they missed it in inspection_comma_ there wasn't much I could talk to him about.  It was gross.  Dirt_comma_ dust_comma_ and gobs of pet hair.  I was breathing it the whole time!
person B: That's awful_comma_ my air conditioner is cleaned thankfully.
