"Just curious how you were going to encapsilate the insulation
Baffles should take care of wind washing - gravity also has to deal with the rule that an object at rest tens to stay at rest but if worried & spraying celulose they have some that can be…"

Sean Lintow Sr replied to Chris Jackson's discussion cleaning or replacing?
"Sounds like expansion / contraction is going on. Replacing - probably not but I would have a qualified HVAC guy look at them to see if things were done right & ways to minimize it / or sound transfer
As for cleaning - cleaning ducts is worthless in…"

Sean Lintow Sr replied to Brett Little's discussion If libraries had blower doors / duct blasters could virtual audits be the dream?
"More like a nightmare...

How accurate is the equipment - how was it handled by others, properly maintained & tested?
How much equipment - just one or more sets, how long is the "checkout" period
How long to teach someone to use & setup, make sure e…"

Sean Lintow Sr replied to Heidi McCullough's discussion ERV to mitigate negative pressure?- seeking a logic check
"Ok but if you seal up where the water heater is - where is the air needed for combustion coming from? - do you have a high low pipe in the area
Before spending a ton of money doing this & that for an old water heater - replace it with either a highl…"

Sean Lintow Sr replied to Michael Johnson's discussion Getting better without being so negative (depressurization)
"Problem with some baths is they don't get enough supply air in so that cuts down on the amount that actually does get exhausted over time - well that & crappy ducting installs
2nd if one goes with an ERV is the air mixing & getting pulled back in (s…"

Sean Lintow Sr replied to Michael Johnson's discussion Getting better without being so negative (depressurization)
"Dehu in a bath - no you still need to remove odors
HRV to bath - only if supply - yes I know some use them for exhaust but that can cause issues in some climates (ERV is definitely a no-no for exhaust)
Range hoods - if over 400cfm a makeup supply is…"

"It's called a wet wall - in this case it should be at least 2x6/8 or even 2 2x4 walls with a gap in center to run all the branches up then hopefully through scissor trusses or I-Joists (which you can drill out that large)
Now you can drill out that…"

"So just to get this straight - you are also doing radiant cooling via the panels? My only concern with that is will you get enough dehumidification if you run the same temp through the forced air unit?
As for heating, hopefully the controls will hel…"

Sean Lintow Sr replied to Ben Stallings's discussion radon mitigation with HRV?
"Not to my knowledge & I don't think it would be to wise to try it - especially with an ERV. An HRV might be somewhat acceptable (no mixing) but you will never get all the pull you need / what you would get with an underslab style.

Of course part of…"
