furnace blowing all the heat up the chimney

I'm tired of people telling me that there's nothing wrong with myfurnace. There is something wrong with my furnace.It's a 10-year-old Amana 45,000 BTU, 80% efficient unit in a 1300square foot ranch style house. This is my 4th winter in this house,and I'm sick of being limited to one habitable room all winter.The air coming out of the vents is cool, around 70 degreees accordingto my thermometer. The exhaust to the chimney is smokin' hot. Theplenum does not get perceptibly warm.I change the filter regularly. The old filter comes out visibly justas clean as the new filter I put in. There is plenty of airflowthrough the unit, as I can feel the cold draft hit my feet from acrossthe room when the furnace kicks in.The flames are steady and clean blue.I have to close off all the bedrooms and heat only the living room andkitchen during the coldest months, otherwise the furnace would run24/7 and the temperature would never get above 62.The pros say there's nothing wrong.

So if his blower goes on at 75 would that be enough to keep his house from heating up? Sure, it's before the firebox heats up, and before the air on the other side of the firewall is hot, but wouldn't the heat catch up?

What exactly are you telling the techs? If you are telling them the air coming out of your vents is too cool, they might be thinking that it is doing the job and tell you nothing is wrong.

Your problem, as I understand it is that you can't keep your home as warm as you would like. Tell that to the techs. Don't over think it, that is the job for the techs.
