    Yeah....

    ...while it's not ideal, it is what it is. There are three returns in the living area, Two are 32", the third one is 16". That's in addition to one 16" in each of the three bedrooms. I understand...

    Another wacky H.O. question....

    ....are return grills highly restrictive? With all those horizontal bars and all, they must block the return/supply flow somewhat, right? My returns in the living area are 32" by about 7 or 8 inches....

    On a similar note....

    .....isn't positive pressure in a house a good thing? Doesn't this + pressure keep the house from drawing basement/foundation air up and through the home? I'm really trying to understand here. Please...

    OK...

    .... the theory of a lot of this is.......somewhat misunderstood by me. I suppose the Skuttle opening all the way up when the blower is on might lead to some type of undesirable condition. I tried it...

    Wow....

    I didn't think it was that involved. But I see the points made (I think). I'm a home owner, not an HVAC guy, and since this Skuttle thing has no fan, timer, etc. can I simply adjust the "weights" to...

    Skuttle question(s)....

    ....I have a 6" Skuttle hooked up to the return of my furnace. An insulated flex pipe runs out the side of the house. I never paid particular attention to it (the flap never opened when the blower...

    Which leads me to another ?....

    .... would less restrictive return grills be of any benefit to a natural gas FA system? I seem to be finding out here that a lot of residential systems are somewhat starved for return air. Which...

    OK, thanks...

    The opening sizes cut into the plates are still most likely larger than the actual free area of the return grills installed.



    Ok, so my 8 X 16 BR return grill isn't considered to be 128 sq...

    OK...

    ...the door open or closed thing- with the door open, more cool (conditioned) air rolls down the stairs-back to the basement return, right? That seems like it would help keeping humidity in check...

    no...

    ...the ceiling is not insulated. It's a drop ceiling. So, you think shut the basement registers and the door at the top of the steps?

    the vent piping...

    So, even though the "vent" is 2" coming out of the top of the furnace; then immediately transitions to 3" ( 3" all the way to the roof)- that's OK? I specifically remember the installer saying that...
