Tenant Complain of Temperature Difference

[Marie S.]

I have a tenant that is complaining that there is a 5 degree temperature difference from the bedroom and the living room. This is a one bedroom apartment in a 100 year old four plex. There is nothing mechanically wrong with the furnace. The technician cleaned the heat sensor just to make his trip worth while. The ducts have been clean. The windows don't seem drafty, but I may get the film for them tomorrow. Any  ideas what the problem could be?

I would look at the dampers on the ducts. The return ducts placement would also have some effect. Another thing to look at would be if the lower temperature room has a basement or crawlspace underneath and the other doesn't. Is one room an addition and so might not be insulated as well? Lots of factors at play but without knowing more it is hard to say.
