Am trying to maximize temperature at register in a room. Am using a probe thermometer and noticed that the temperature would rise a couple of degrees after I had inadvertently closed down the register somewhat.
Since there was little change in air flow, does it make sense to use this technique (close down slightly) on any/all registers? Would it increase throw? Effect on static?
All dampers are wide open, or nearly so. System is quiet, runs 2 - 3 cycles per hour, depending on outdoor temperatures. Just that 1 or 2 rooms on north side sometimes cool.
