Blower door test
I am new to the field. I just took my brand new blower door out of the box and ran my first test though tectite software. My official training is at the end of the month sooo until then I need some help interpreting the results. From what I understand my house “scored” fairly well. 550 on ring B for the depressurization and 650 on the pressurization. The results sheet also showed 18.6 CFM and .14 ACH on depress. and 20.9 CFM and .16 ACH on pressure. I did not close off any exhaust fans, return registers because nothing that I have seen/read said anything about that. The house has a crawl space and attic.
My questions are:
What can I interpret from the scores if I tested on a 1000sqft house? How much does sqftage matter? Do I need to seal exhaust fans to the outside when running the test? Any good research website for novice?
