Another thermal bypass:



These ever rust out? What happens then??



Ever wonder why mobile homes have big energy bills?



So that sliced up road barrier and filterglass insulation, that's an open plenum return??!

How HVAC guys can tell the problem's not on their end:

I'm guessing the icicles are from condensation? Damn glad we don't have winters like that down here! Looks like that would destroy a house.

the ice is from heat loss.
The attic heats the snow load on the upper level of the roof and melts it. As the water rolls down the roof line it hits the soffet area of the roof line and because the soffet is the same temp as the outside temp it refreezes and creates the ice dams.

Interesting. I just built a house and had all the roofs foamed. Looked at my roof this morning. 34 degrees out, light frost on all the shingles, 68 inside. I'm impressed!
