Manual J, attic insulation
Just quick question, when measuring the rooms, windows, etc., to come up with proper sizing for geo, should the contractor be looking at attic insulation also? I had 3 guys over so far and none of them went into the attic or even asked about the amount of attic insulation. That seems like it would be a huge factor in determining heat/loss and tonnage?
Another point of consideration...
Dealing with a contractor than not only does the manual J but also understands thermal loading from pressure barriers, as well as, infiltration and exfiltration loss/gains.
