We asked for an ultra high efficiency unit and to get a rebate from the gas works. It turned out that unit had been down graded in the mean time since we ordered it and it didn't quite, it was like 1.2 low to get this rebate. In fairness they did, in between the company, the manufacturer, and the supplier, they made good on that warranty, on the rebate, so I didn't loose out on it. They did take the effort to do that. These peripheral parts that they have, I don't know, maybe their all made in China, it's junk and there's no other resource for them.
