I have a new construction home and have always wondered about the location of the thermostat. It was placed in a small alcove in a hallway connecting the living room / kitchen / dining to the bedrooms. It seems like a good spot, centrally located and right by the return air, but I have read a lot of bad things about placing it in an alcove like this.
There does not seem to be any consistency in room temp. Some days I have to put the stat on 72-73 just to be comfortable, other days that is just way too cold. There also seems to be some humidity problems from time to time.
If you look at the attached pictures, the only thing in that alcove is a bath and a closet, and both doors have to stay closed. I am some what knowledgable with HVAC systems, but am in no way an expert, so I thought I would ask the opinion of some professionals.
It seems to me that the stat is not accurately reading the temp of the return air as maybe the air is passing right beside the stat instead of past it. Of course I could be wrong.
