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.
