Spending our first Winter in our home we purchased in the Spring. Our second floor is pretty cool and when the last owner undertook renovations on the main floor and removed walls, air ducts that ran to second floor rooms were cut completely and end on the main floor. At this point we have several cold air returns but only one working duct which pushes warm air to the second floor which has our master and two other bedrooms (currently unoccupied).
There is a 10 degree difference in temperature between the main and second floor. I have checked the small attic access panel which has about 4' of headroom and there are bats of pink insulation in the middle of the second floor where there is a dormer which spans from one side to the other of the house. But I have no real access to the roof over the dormers or at the front and back of the house where the roof is peaked, though I do see there is about 4-6" of loose fibreglass insulation.
With finished dry wall ceilings in the hallway and all three bedrooms, do I have any options to insulate? The roof was re-done a few years ago with several vents (none ridge), though we will re-do the soffit and fascia which wasn't done at that time.
What should I do? Insulate, extend the cut off heating ducts to the second floor again?
Now I know why the last owner had electric fireplaces in all of the bedrooms!
Thanks for any advice.
