Buy from a Moonlighter?

That's what these people did. Let's see, what was wrong...

1. The furnace is oversized.

2. Despite being oversized, they couldn't heat the house. Why? Cuz the gas pressure was set so high that the furnace cycled on limit so much it didn't run fire long enough to produce usable heat.

3. The flue to the chimney is undersized (3")

4. The flue went DOWN 1' to the opening in the chimney.

5.The chimney was not lined per National Fuel Gas Code.

6. The A/C is a 3 ton but the blower speed was set on high, for a 5 ton system.
