I'm having some comfort issues with my heating system. Overall, I think the room balance is pretty good, but not the hallyway. When hot air is produced, most rooms are within about 1 degree of the others. The bathrooms heat faster and hotter, as they tend to have a little more air flow than required, but I like the bathroom to be warmer.
As the house is heating the hallway eventually reaches the set temperature (70F) and the thermostat turns the heater off. When this happens, most of the rooms are 1.5 degree hotter than the hallway (71.5F). I'm kind of too hot by this point, as I like the rooms at 70F and not 71. I keep the fan running continuously (Bryant Evolution system) and as I do that the hallway seems to lag the rest of the house quite a bit in cooling down. All the other rooms have dropped 3 to 4 degrees (to 67-68F) before the hallway has become cool enough that the thermostat kicks the heater back on (thermostat still reads 70F). So I'm getting a little cold before the heat kicks back in again.
The thermostat is located in the hallway and most of my air returns are located in that hall too. The air on the hallway floor (which is where the returns are) seems to be slightly cooler than the air at the top of the hall, so this could be part of the problem (about 1F difference). Also, there is a bathroom in the middle of this hall, and I'm thinking that some of the heat in there is coming right back out and heating the hallway. Since there's almost no heat loss in the hallway, I think this may be why things are lagging.
Any suggestions for how to fix this problem? Should I relocate the thermostat in a room that is more representative of the rest of the house? Is running the fan continuously the right thing to do? Note, I used the same thermometer for all room temp measurements, and it matches the thermostat thermometer to half a degree.
