Ed Minch replied to Paul Raymer's discussion Stud cavity air returns
"I work with the State of DE on code language, and for 2012 there was was backlash from the HVAC guys about panned returns.  We managed to get language stating that they could be used only if the ducts are not required to be tested (i.e. all…"

Ed Minch replied to Paul Raymer's discussion Stud cavity air returns
"Has anyone documented mold inside a panned return?  We discourage the practice for different a reason.  We frequently see a 4 X 12 return grill = 48 in2 (less a bit for louvers), but the hole in the bottom plate of the wall is 2-1/2 X 10 =…"

Ed Minch replied to John Carton's discussion Insulation touches underside of roof in home with no soffit or soffit venting.
"I don't think it would be a problem provided there is no large source of interior moisture getting into the attic, especially in a cold climate.  With that in mind, a thorough sealing of the attic floor - including those plates at the…"

Ed Minch replied to Jerry Needham's discussion HVAC Question about running fan continuously VS setting on Auto so it runs when AC or furnace runs
"It all depends on the house - attic ducts, older unit, poor return capability - but I like the thermostats that have the "CIRC" circulate mode that operates the fan for only a portion of the time.  In my experience, it does the job…"

Ed Minch replied to Dav Camras's discussion Adding blown insulation to poorly installed batts?
"After lifting specific batts for blower-door/IR/experience guided air sealing, (rarely with 2 part foam) my crews will use a narrow rake to push batts down against the ceiling and around wiring and framing anomalies.  Then we will blow on top.…"

Ed Minch replied to Ed Minch's discussion Open return in the group Hall of Shame
"This is a return high on a cape cod knee wall after we took off the grill - the glove has a hand in it.  That is a supply duct running up through the return, and the angled roof above the knee wall attic visible through the hole"

Ed Minch replied to Greg Labbe's discussion Easiest way to convert 2"x10" into 2"x5"! in the group Hall of Shame
"Might not be as bad as you think - if the load needs a 2X10 out in the middle of the span, a 2X5 at the end might be within spec.  That is assuming the plumber actually thought about it."

Ed Minch replied to David Meiland's discussion Air-sealing 101 for new home builders who have failed their blower door tests
"The three things I would do first is to try to find any big holes - returns missing pans in the attic and stuff like that.  Use a scanner to check interior cavities. Second, I would seal the wall/ceiling joints in the attic - we have found an…"

"Bill As an industry we have been sealing existing houses and ducts using diagnostic equipment for guidance for almost 40 years now. We had organized existing home sealing a couple of years before we had organized new home sealing. Ed"
