These folks were chosen by the home warranty company. They were surly on the phone, and then insist on a "disposal fee" for the old unit. Of course this is a scam fee, because a recycler will pay you to haul it off. They also told me that they had to haul off the old unit, it was an EPA requirement. If you google AC disposal fees, you can see that this whole line is total BS. I finally decided I would pay it, but then they refused to provide the service.
