Thanks for all of your input. I don't think there is any easy answers. In response to Hogwildz above regarding the statement "if it can't get the basement above 72 then how can it affect the rest of the house. My thought is that since it is fairly even both down and upstairs it is confirming the fact that I have decent circulation and the air is being mixed quite well over the entire 3000 sft. I think if I were heating one room only with a small opening to the rest of the house it would be different and that room would be like an inferno. From all of the info everyone has fed me, I am concluding that the lower than expected heating capacity is a combination of a partial-basement application and heating nearly 3000 sft in a cooler climate.
