Sean Lintow Sr replied to Rob Madden's discussion Determining Duct Leakage based solely on blower door and pressure pan testing
"You can get an approximate number but nothing legitimate / allowed by code Easiest method is run blower door with ducts & unit sealed off & then open them up - difference is your supposed leakage"

Sean Lintow Sr replied to Steve Nations's discussion high rise humidity

Sean Lintow Sr replied to David Meiland's discussion Air gap above floor insulation--how big is the impact?
"BTW David, if you would like to mention anything to the builder it might be to consider using radiant sheathing in that area - shiny side down of course :) That should help keep the heat up where they want it & hopefully help with any worries…"

Sean Lintow Sr replied to David Byrnes's discussion When can an oversized A/C be a good thing?
"Well you are in an interesting market as humidity levels there are almost non-existent thus you don't need the long run time to help pull that "heat" from the air. With that set the temp lower just before on-peak & pre-cool the…"

Sean Lintow Sr replied to Brett Little's discussion Do ductless systems do better on the HERS?

Posted on November 19, 2014 at 10:48am 0 Comments

Posted on January 8, 2012 at 1:00pm 0 Comments
