I Was Wondering If Anyone Doing The Energy Audit,can Point Me In The Right Direction To Get A Blower Door .new Or Used.
Check the link - probably the best door out there.
If you are looking for used, try Ebay or Craigslist.
Ditto. You’re looking at $2500 - $3000 new. Spend a little more and get DG700 digital guage. Not sure if they’re even making the analog guages anymore.
