If you do not buy your oil here, they WILL not service your furnace. I contact them several times, and they were very rude in the fact that they only service the people who buy oil from them. I mentioned to them that they are turning business away by not servicing other clients who request it. They did not seem to care. I even mentioned that they installed the heating system in the house I now own, and that did not seem to matter. SO, I have moved on, see my other review of Reddings.
