Wow I thought a drafty house was bad! What do they call a drafty boat? Sunken would be my guess. Better account for x 22 in my case
I have the original wood windows, not in too bad of shape either, still on my house. The storm windows could definitely use replaced though.
That is indeed the problem there. There is one room I MIGHT be able to see the coils, that's above my office. Anything else I definitely can't see. That is after I dig out the insulation, there is around 11" above all rooms in the attic, about 8" above the garage. So if the coils are in the drywall themselves I am definitely screwed.
