vents

  1. Eggs? Fungus? A Block of Soap?? Found in one of my vents by smelling a strange odor.

    Pest Control
    I've recently been smelling a strange odor from my office area these past few days, and I checked my vents and discovered this (in the photos). It is a purple, bar of soap-like substance with bubbles/air pockets on top. It kind of reminds me of a moisture absorber. There's a white ring where it...
  2. When to open/closed vents when Crawl space is partially encapsulated in North Carolin

    Building & Construction
    Hi, I just partially encapsulated my crawl space (10" vapor barrier around the perimeter). I have a ventilation fan in one of the vents installed. I was thinking what should be the other vents positions (open or closed) during each season: spring, summer, fall & winter? I live near Raleigh...

    General DIY Discussions
    Hi, I just installed a Tjernlund V2d ventilation fan. I have all other vents open recommended by the Tjernlund. Here in North Carolina, we are going to have a thunderstorm and I checked the weather and will rain for 8 days non-stop heavily and the humidity of the air outside will be over 95%...
  4. Seal other vents when installing a ventilation fan

    General DIY Discussions
    Hi, I just purchased a ventilation fan and want to hook it up. I had one with all other vents open for 6 days now the wood moister went down from 23 to 14 and I am very happy about it. Now, if I seal all other vents, does it even reduce it more?
  5. Some vents blow cooler air than others

    HVAC
    My furnace blows up to tubes that immediately split left and right as seen here: The route to the left goes the length of the house, and T's off perpendicularly a a few times, leading to a handful of vents across the house. The route to the right just leads to two vents, and both are much...
  6. Is this a problem? (what I found in my attic)

    HVAC
    Our house is in central Nebraska. It's about 12 years old and we're the 2nd owners. Utility bills aren't outrageous. The house is a split-level with walk-out basement. The view you see is above the main-level bathroom - which is above the basement bathroom. I found it odd that the bathroom...
  7. Need to Fix Just Everything; Know Enough to Be Dangerous

    Remodeling
    I have skimmed through the posts and decided to go on and start a new one, since this is gonna take a bit. The start date for my project is actually uncertain-awaiting the funding to arrive and hiring contractors and whatnot. My remodel will be in my parents' home and I want to make this great...
  8. Gable mount fan with no undereave vents

    Roofing/Siding
    I bought a house that was built in 1951. The house has really no eaves around the entire house, so there are no undereave vents. The house does have a Gable mounted vent fan. I needed to replace it because it makes some horrible rattling noises, but when I was reading the instructions, they...
  9. Pressure Test for Drains

    Plumbing
    We are DIY remodeling a 100 year-old house in OH. We replaced much of the existing plumbing (over 70%) with new PVC to match the new layout. The glue and primer recommended for PVC were used. All lines were "water tested" with no leaks. Inspector requires a pressure test of drain & vent lines...
  10. Open Beam Ceilings

    Roofing/Siding
    I live in the caribbean where open beam peaked ceilings are a common design. These typically have a T/G cypress exposed with a 3/4" plywood layer over it and either metal or hypalon type weather coating. Most are either peak or hip designs I am looking for imput on how to vent, preferably...

  12. Various A/C questions - return vents, leaking air in unit, hot upstairs...

    HVAC
    So I'm living in a 2 story house with a basement built in 2001. The house has 2 AC units one for upstairs, then other for downstairs and basement. This is a rather large house and the cooling/heating bills are more than what we'd wish for. The top of the house is the hottest (not by much) as one...
  13. Duct Disconnected in hard to reach area

    HVAC
    There was hot air coming from one of my vents so I went up to the attic and could feel cool air coming from the area it was in. I am assuming the ductwork has been disconnected somehow. The only problem: it is in an area I cannot get to. How would I go about fixing this?
  14. venting and moisture in attic

    Roofing/Siding
    It seems to me that one of the principal functions of venting is to reduce moisture in the attic. People seem to make a lot of venting for the preservation of the shingles or to cool the attic. But I figure that if a roof is made to take 160 degrees outside having a hot attic in itself doesn't...
  15. Ridge vents?

    Roofing/Siding
    I am confused about venting. I’m getting quotes to remove and replace the shingles on our house, about 16 years old. There are existing soffit vents. It looks like continuous vents in all the soffits - in the attic I can see light around the whole perimeter. One contractor suggested ridge...
  16. A/C grille extensions

    HVAC
    I live in a 1st floor condo and I have decided to add green glue and a layer of 5/8" drywall to the entire ceiling and 2 shared walls. How do I extend the a/c grilles down an extra 5/8" to accomodate the new finish height? Do they sell extensions of some sort or do I just attach the finish...
  17. Air return wall grille - slats in which direction?

    HVAC
    :confused1: We just had work done in our living room, and the large (a little over 1'Wx2'H) air return vent grille was removed. I just painted it to match the wall. The air return vent is in an upper corner of the living room wall, at the ceiling. (Our house is around 1970 vintage.) The...
  18. Adding vented soffiting

    Building & Construction
    My ranch house (w/hips) was built back in the 60's and had aluminum soffiting put on then (at least I assume then, as it's sure showing its age). There's only about a half dozen vented pieces for the whole 2000 sq foot place, though. Is there a way to replace solid ones with vented ones that...
  19. How to vent eaves if no overhang, metal roof, Texas?

    Roofing/Siding
    I'd like to replace my shingle over 5/16" OSB (excellent condition, but cheap materials) roof with a standing seam metal roof. The "attic" interior is inaccessible, just 18" high at the ridge, down to nothing high at the eaves. There is no eave overhang; the roof stops an inch past the...
  20. Remove and replace single duct span

    HVAC
    I am doing some structural work in my basement and the only way to get in the steel is to take down a span of ductwork, or to cut it. It looks like I can take out the piece I need to, it's about 3 feet long, on one end is an elbow that turns it upstairs through the floor, and the other end it...
