First Blower Door Test

So I managed to get suuuuper lucky for my first blower door test.  And not because I got a great score.  Right now I’m still at about 1.2ACH 50, or about 900% better than Austin requires for air tightness, but still not good enough by Passive House standards.  What was lucky was that my blower door test was done by Greg from Attic Care, and he lent me his equipment for the weekend so i can spend as much time as I want improving my score.

First of all, I had never even met Greg before today.  Second of all, the blower door, and his thermal imaging gun are worth more than my truck.  Greg was so impressed with the Passive House concept that he is excited to see it work.  Even though my house is already “the tightest he’s ever seen” I’ve still got work to do.  I loaded up on tape, spray foam, and caulk, and I’m ready for tomorrow.  But for anyone in the Austin area needing attic insulation, an energy audit, or blower door tests, I would highly recommend Attic care.
