Paul Morin commented on Sean Maxwell's blog post The Better Blower Door Test for Multifamily Energy Code
"Hi Sean, Wow, 20 ACH50 is normal!  I have gotten calls for parts of Flordia where they have to use Ring A for the first time and are confused.  I thought that was bad.   We have had a distributer, Pro Clima, in New Zealand for a while…"

"Thanks Sean for a very will stated article.  I agree with your assessment of the importance of compartmentalizing apartment units.  If the only focus is on tightening the exterior enclosure and leakage to adjacent spaces is not addressed,…"

Paul Morin commented on GEORGE LEVOSINSKI's blog post Blower Door DG-700 Meter drift
"Hi George, It sounds like you have a few things going on here.  If the DG-700 is not going to be used for extended periods of time, it is good practice to take the batteries out.   We recommend that the DG-700 be recalibrated every 3…"

Paul Morin replied to Stephen Standley's discussion Which reading is more reliable on a Minneapolis Duct Blaster?
"Sorry for chiming in so late.  Sean’s comment early on in the discussion was the closest to the point.  160 CFM is off the calibration charts on the high end.  Your Duct Blaster® Ring 3 may be able to top out at 160 CFM with…"

Paul Morin replied to George J. Nesbitt's discussion Duct Testing High Velocity Systems
"if the duct leakage is relatively low, 200 cfm or less, the pressure in the duct system will be quite uniform and either location will give consistent results.  If the duct leakage is high, over 500 cfm, we recommend that you do two…"

Paul Morin replied to Darrel Tenter's discussion Questioning W.C.C.
"Darrell, I am confused by your last paragraph:  ‘I’m not suggesting that we discontinue combustion safety testing. I question whether the risk reduction (or lack of) merits the complexity and time…"

Paul Morin replied to Tim Marlett's discussion Blower Door Depressurization and the Human Ear
"This article ( shows that the measured cabin pressure in an airplane changes by 5000 Pa during flight.  This will certainly cause discomfort but is unlikely to cause damage.  I wouldn't be…"

Paul Morin replied to Colin Genge's discussion What is the value of using a pressure pan to test outlets?
"David, you could use the Exhaust Fan Flow Meter to measure air flows above 10 cfm through the recessed light, but you would need to pressurize the house to 50 Pa.  For flows below 10 cfm, you would need to make the hole in the Exhaust Fan Flow…"
