Last year we had Wes Diskin from Barron's come out to help us with heating issues in our home - we had cold rooms, warmer rooms and the furnace seemed to be running constantly in colder weather.
Wes suggested re-zoning our home (at 1600 sq ft we only had the one zone - the main room/kitchen/dining area). We went to three zones - main room, front bedroom/bath/study and master bedroom/bath. What an amazing difference this past winter! Every room in the house was comfortable (and evenly heated) and the furnace ran much less often.
I would highly recommend Barron Heating & AC - the installation went smoothly, everything was explained and the place was left spotless.
