We moved in a rental home which does not seem very old.Does the heating system need to be serviced?
You need some method of moving the warm air down into the room. If this depended on ceiling fans (not particularly comfortable when no heat is being applied), there is usually a rotation direction switch on the ceiling fan (do not switch this while it is rotating). Summer, you want it to blow down into the room, to help cool things below it. In winter, you want it blowing on the ceiling, which cause the warm air up there drifting down into the room.
Hardly any info here so let's say that rental home owners are not exactly concerned about maintaining their equipment until a tenant says something about it. Change the filter.
