"The oily stuff drips out when the cover is opened.  Unfortunately I don't have pictures.  Doesn't seem to be below the motor.  Just wanted to know if anyone else had seen this phenomenon."

Paul Raymer replied to Paul Raymer's discussion Oily Stuff in ERVs
"There are two different ERVs both with the issue.  Air on the return side is coming from the return duct and being pushed back into the return duct.  There is a fresh air feed from the outside.  No stove connection and the filters seem clear."

I visited a house a couple of days ago that was full of HVAC issues.  About 4000 square foot house with multiple systems including two poorly installed ERVs.  Summer house, so it is infrequently used.  When I opened the covers on each ERV an oily…

"My furnace is sourced with a hot water loop from the water heater.  I kept turning up the water heater temperature until the temperature/pressure relief valve started blowing water out onto the basement floor.  After a lot of air and pipe…"

Paul Raymer replied to Eric Miller's discussion Best Exhaust Fans - your opinion?
"I certainly agree with Mark regarding the quality of the installation.  Leakage around the housing after installation is usually the major culprit in leakage.  In my testing, I have found that the majority of backdraft dampers in fans work quite…"

Paul Raymer replied to Haley Keegan's discussion Baffles without soffit vents?
"Sean -  I'm curious as to why you say the insulation should never touch the sheathing?  That's one I haven't heard before.  Insulation in walls touch the sheathing.  I've never liked soffit venting, and certainly baffles are critical when soffit…"

Hope you are doing well and enjoying life!

"Thanks, Franco.  I am just curious if this company "Green Home Solutions" is legitimate.  It makes me wonder when they misspell one of their key components - Probitoics instead of Probiotics. "

Seems like a good concept to franchise cleaning up mold in people's houses.  People are afraid of mold.  And cleaning it up with something called "Better Air Probitoics safe, all natural fogging solution" that will "restore indoor ecological balance…

Seems like a reasonable use of space and materials and saving in costs to use a stud cavity as a conditioned air return.  But is it a good idea?  The inside surface of naked, unpainted sheetrock is heaven for mold.  We know that these cavities are…

"Ah, but there is a backdraft damper on the fan!  I've tested these before and found that they are generally quite tight, as you say, but something unusual is happening in this case."
