Wonderful! Didn't catch the young gentleman's name, but he saved a cat's life. Cat and two friends had pulled off vent cover five days ago. Other cats came back into room, but I needed to put that vent cover back on and this cat wouldn't come out any of the other vents. We had made things worse by scaring it with the noise of a leaf blower and Service Tech found kitty in Central Air unit, where he would have been killed. Thank you so much!!!
