When any upper level is hot insulation is almost always the reason.
And why else wouldn't it be? It could be that the air conditioning does not reach or blow hard enough into the upper level. But that air pressure is an easy check.
When air is blowing well through a register I have my client feel it so they will know when the mechanism isn't blowing properly.
But going into the attic we found our answer there.
Insulation was indeed the reason here! Large areas without insulation were evident. And along the edges of the roof the condition was the same.
Thermal images of each of the photos above looked like this.
The insulation all over the attic had huge gaps where there wasn’t any present. And insulation, when it was present elsewhere, was very thin.
And all along the edges of the roof, front and rear, the insulation was similarly weak.
How does that add up? To a hot upper level!
IMAGINE HOW COLD THIS UPPER LEVEL IS IN THE WINTER!
My recommendation: things happen for reasons. Usually the reasons are clear. In this case not only were they clear, but indisputably identified with both photos and thermal imaging. This is an easy fix, but a very important one! Air conditioning and heating simply CANNOT be effective when a lack of insulation is getting in the way! When there is no thermal barrier temperature and humidity will overcome. And that was the case in this house. And an uncomfortable upper level was the necessary result.
