I DON’T NEED TO REPLY TO ANYONE’S STATEMENT. I HAVE A QUESTION I HOPE SOMEONE CAN ANSWER. IT IS 85 DEGREES OUTSIDE AND MY HEAT PUMP IS RUNNING COLD AIR AND ALL OF A SUDDEN IT STARTS BLOWING HOT AIR. I JUST HAD A NEW A-COIL INSTALLED ON 9-1-15 ON TOP OF MY FURNACE BECAUSE IT WAS BLOWING HOT AIR. CAN SOMEONE THAT KNOWS WHAT THEY ARE TALKING ABOUT TELL ME WHAT THE PROBLEM IS.

Yes, that was my first
Yes, that was my first thought as well. This can’t be that common? Really?

Not quite related to this particular detail, but I am trying to get my builders to get away from using a plastic vapor barrier behind the drywall and move over to air sealing the attic floor with foam packs after the drywall goes up. No plastic = proper adhesion to drywall and top plates. It’s easy to foam ALL penetrations (and potential leaks) from above, then use a vapor barrier paint or primer on the drywall.  
 
Presently, many leaks are missed, especially electrical boxes/drywall intersections as electricians only air seal from inside the boxes, before the drywall goes up. Unfortunately the contractor mantra tends to be “we fear change”.  
 
If our cars leaked like our homes there would be anarchy in the streets. Mandatory blower door testing!!

I tend to go along with Doug K. on this one. How is it possible to blower door test a house with an integrated garage space within the envelope? That floor above the garage should be considered conditioned space unless the entire first level is garage/basement like we have with elevated homes in a flood plain. Now if the walls between the garage and living space are shear walls and sheathed with OSB or plywood, you can address this in a different manner.
