Energy Savers put in a unit for me, but I'm not happy with the noise. It's in the hallway right there, but my old one wasn't that noisy. They've been trying to correct the problem, and I think they just might have to put it up in the attic; I don't know. But they are professional and everything, and they've been working with me, I just have to call them and tell them the last thing they did isn't working for me. That's all, they're working with me so far.
