Can installing heating/cooling ductwork be a do it yourself project?
Q. A family member out of state got me a furnace thru his company at cost. I picked it up and now have it home. I had hot water radiators, convering to gas forced air heat and central air. I do not have any ductwork however have a old servants entrance staircase that I was going to use so walls, etc did not need broken out. Is this something we can do on our own, we have remodeled many other things, and done plumbing and electrical. I just cant find anything on ductwork.

A. Duct work takes special sheet metal benders and crimpers and such. You might be able to have them manufactured and install them your self if your handy. I consider myself very handy and am going to hire someone that has all the right tools

What is the best way to fill in and seal off ductwork under a concrete slab?
Q. I have mold in my ductwork under our concrete slab floor and need to fill it in and seal it off completely so the mold will no longer be a problem. I have to seal under the furnace and also three floor register holes. I was told to seal them with concrete. It seems it would take a lot of concrete to do this. Has anyone had any experience with this type of thing with advise to offer??
Asked by Joe C - Sun Jun 8 00:20:42 2008 - - 4 Answers - 0 Comments
A. I'm assuming that you've already tried spraying bleach into the ductwork to kill the mold. Concrete would add some strength to the slab. If the ducts are way below the slab, it may not be necessary, and you could fill w/ sand & top off with concrete. I bet it wouldn't take all that much concrete to fill them anyway, and it would be much easier to pump it than to mix it by hand.

A. Duct work carries very little or no condensation. It may get hot/cold but not so much as to cause a mold prob. If there is plumbing ,that should be wrapped with foam insulation. No need to worry.

What is the most efficient use of sheet metal in ductwork construction?
Q. When designing ductwork what is the most efficient use of sheet metal?
Asked by Richard W - Wed Jun 6 14:44:42 2007 - - 4 Answers - 0 Comments
A. Most efficient use is to size your rectangular ductwork to the common sheet metal sizes so there is less waste, remember an allowance for joints. Might have to be in touch with the sheet metal contractors so see what is readily availabe. Square duct will have less of a perimeter since you will need to keep the cross sectional area the same.

You should shop around, even check with friends if they know someone who works in the HVAC field. This guys do work on the side for extra money and can definitely give you a better deal.

Is there a way to place a interlining inside of the ductwork with a central heat and cooliing system?
Q. My ductwork has holes due to a flying squirrel...air flow is comprised greatly due the holes he has eaten in the duct I was wondering if at each vent you could insert a sleeve of some sort that would comform to the duct and therefore seal the hole My ductwork is not the round accordian looking stuff...it is square and fairly hard in texture. The ductwork is inside the wall not able to just tape the holes up with duct tape wish it was that simple!! Come on folks I really some help maybe from someone who works HAVC

A. I've not heard of that problem. I assume you are talking about flexible fiber glass/ plastic film covered duct, not metal duct. I'd just go with Duct tape on the outside of the duct to seal the leaks. I can't think of any liner that you could insert from the inside that would follow the contours of a flex duct, yet be rigid enough to maintain an air flow path. Whatever you do, first SHOOT the squirrels.

How do I stop ductwork in my attic from "sweating" in the summer?
Q. The duct work in my attic "sweats" when I have the AC on in the summer. It ends up dripping down the walls or stains my ceiling. What can I do to stop that from happening?
Asked by Craig_Anderson - Mon Apr 30 10:45:55 2007 - - 6 Answers - 0 Comments
A. Insulating the duct is the only way to stop the condensation. Neoprene type insulation is best. Use fiberglass ductwrap if that is too expensive. Completely seal all ends and seams. If any humidity can get under the insulation, it will condense on the duct and ruin the insulation. DO NOT go to Home Depot for advice. I wouldn't ask them how to heat water. Go to an insulation supply store, or an insulation contractor. Remember, you must completely seal the duct so no air can come into contact with it.

I am confused on how to run ductwork behind a wall for a Range hood on a 1st floor kitchen?
Q. Essentially I want to install a vented range hood. I will need to run the ductwork to out the roof if possible. The wall on which the hood will be mounted is the common wall. The wall is finished. I haven't got the chance to check but I'm sure it is only a stud's width. The duct will have to go up to the second floor up the wall and into the attic and finally out the roof. I don't think this is possible? What would be the best method of running a duct. Do I essentially have to build a box around the duct??? Another option I just though about is running the duct down into the basement and then out the wall. Is this ok (code wise)
Asked by scanjet - Tue Sep 5 14:25:17 2006 - - 4 Answers - 0 Comments
A. Ductwork is made to fit inside a 2 x 4 wall. (3 5/8"). Several problems occur while trying to make it up to the roof. Top plates on the first floor and top and bottom plates on the second floor will have to be cut for the ductwork. This will involve cutting the wall out all the way up to get it installed. No electrical wires, telephone wires, cable, plumbing etc..., may be in the same space. You can furr out the walls to enclose the ductwork through the first and second floors, however, it is hard to make this blend naturally with the rooms. Local codes will probably not permit exhausting through the basement and then out because of the fire danger of catching grease in the 90 degree turn below the first floor.

A. This type of question CANNOT be answered unless someone can actually looks at the job. Most local contractors give FREE estimates. My question is why replace it? Is it leaking? Is it poorly insulated. It would be much easier to reseal and reinsulate if it is hard duct. If it is flex duct then replacement would be a good option and is easy to do.
