    I am putting in a very small 1/2 bath in my finished basement. I am trying to figure out the best way to vent and exhaust fan to the outside. Unfortunately, the wall that butts up to the foundation does not have a window and it sits on the opposite side of my patio steps. Of course the joist run...

    Hi All, I'm looking for advice on which size of trunk & ducts to use. I've used a ductwork calculator that is associated with Menards and they drew up a plan but it doesn't take into account some things that I need. I have a 1 story house with a basement. The furnace is in the basement. I...

    I would like to move my dryer down the wall by about 6 feet, but I can't move the exhaust vent (window and gas meter regulator within 36"). I am going to use cabinets which will sit on adjustable legs, so I will have about 4" of space under the toe-kicks. Can I use this space to run my dryer...

    I have a 1973 double wide mobile home. I have a Bryant 80 series gas furnace. The past owner seems to have messed up and jerry-rigged the ducting. And I can't seem to find any manual etc. that answers my question. So I'm going to try my luck here: Mobile home furnaces have two heat duct...

    I have a Bryant 80 series gas furnace. I think it's from 1973. It's in a doublewide mobile home. The past owner must have destroyed the original round crossover furnace duct tubing. They put in it's place cheap foil type tubing (don't know what to call it) and it's like 8 inches which I...

    Hi - this is my first post/time on this forum ever so please bear with me if I’m confusing or doing it wrong. Home Depot just delivered and installed a gas dryer at my home. I knew nothing about proper vent installation at the time. After the installers left I started questioning the common...

    So, I bought a new downdraft since the last one was busted and noticed when I was taking out that the previous owner had crafted a "metal box" that allowed the air to be pushed into the box from the downdraft and then it redirected it into the pipe into the floor which goes under the kitchen...

    I'm framing my basement ducts now and they are quite low. I was thinking of using 1x4 lumber at the bottom and 2x4 at the sides. Is that ok? Or can I just use plywood instead of 1x4s just to save more space.

    I was shortening a circular duct in my bathroom and when cutting it I uncoupled it from the main. I went in the basement and the wall and pvc to the radon system are in the way. On the other side is the main return ductwork. I'm a small enough person to crawl between the joists but I would have...

    I have a section of 8 x 20 rectangular duct, and I want to adapt it to connect to an 8 x 24 section. I have this adapter, and it says it is "pre-assembled with boot clips for easy snap-in installation". I don't see anything that this would snap into. The only options I see involve cutting out a...

    Hello all, first time poster here. I did try searching the database, so forgive if that has been discussed before. The house my family purchased about 6 months ago lacks (or so we thought) any hvac vents or returns in our finished basement. The other day, I removed a drop tile and poked my...

    I am in the process of finishing a basement. My contractor left an air register boot that hangs below the drywall by about 1" from celing. What is the best way to cut? Tin snips can't really sit against the ceiling (celing register) flush enough to make a good cut. Almost as if you need...

    I bought a house back in May 2017. House built in 1957. Forced air system. Great furnace, however I believe the duct work needs improvement. Case in point right here, I guess... I was messing around in the basement to see what was under the suspended ceiling tiles (...just for my own knowledge)...

    First time home owner here, Yesterday, while running the dryer, I noticed water dripping from the dryer exhaust piping in the basement. It is getting cold outside and my basement is not heated. My guess is that the hot air is condensing in the pipe (which runs through the basement false...

    Hey there! We have a less than ideal under-stair broom closet that's being used as a 'server room' for a small studio environment. There's also going to be a lot of "You shouldn't ___" in regards to the setup, but we're working the best with what we have. The server room has been used for...

    Hi, I run a small HVAC business out of Westchester, NY. We were wondering if anyone has used regular R8 duct wrap (fiberglass) on top of R8 bubble wrap. Essentially double wrap the duct. Does it make the vents sweat? Does it disrupt the vapor barrier? Are there any major drawbacks or...

    Hi! I'm new to the site - thanks for hosting this fantastic resource! I found the DIY Chatroom because I have some questions that I'm trying to answer about replacing my downdraft and fan with a much more powerful version. Yes, I realize that an overhead hood would be much, much better but...

    Hi, we have some HVAC ducts that run along the ceiling of our garage. I assume they are feeding the rooms above them. Currently they have some really old insulation and some kind of white HVAC tape covering them. Its coming loose, it wasn't very well done (was like this when we moved in), and...

    Hi, I have central A/C and the furnace is in my basement. All of the duct work travels in the basement ceiling. A section of the duct work is dripping water at the joint. I live in a townhome and as the duct work travels, it turns 90 degrees up along the wall separating me and my neighbor. It's...

    Hey all, I am in the process of doing a remodel and, after opening up a wall I want to remove, I see ductwork running through it. I want to eliminate this supply line as it seems to only feed one register in a small bathroom that we keep closed. I also need to relocate some returns on this...
