Here's my question. I bought a house and didn't know there was no insulation in the walls, so I had insulation blown in, and I replaced all the windows, my problem is that its cool about a foot or two on the floor and the heater runs constantly if I turn it past 70 it don't shut off the back two rooms are always chillier the cold air returns are in the attic. I was wandering what the problem is the only thing I haven't replaced is the heater but it seems to blow warm air out it's a gas fired low-hi boy either model gh3a75 or a gh4a-90. My heat bill was $200.00 last month and that seems high its only 1100 sq. feet and I'm gone in the day time hrs I leave it about 68 when I leave??

Don`t know where you live but $200.00 is n`t bad at all where I live. You didn`t say if there was any insulation overhead in the attic. And cutting the tstat back from 70 degrees to 68 degrees ain`t going to make much difference,, other than looking into the insulation thing,, you probable need to get a pro to come out and do an overall inspection

What kind of pro, heating or what?
