How do you relocate ductwork?
Quote from the video:
Quote from Youtube video: And our goal is to open up get rid of everything on that side right there next to the chimney. And get rid of this first duct. And put all the remaining ducts in that cavity right there.
Does ductwork need to be grounded?
National Fire Protection Association (NFPA) requires pipes and duct be constructed of metal and be grounded and that non conductive pipe or ductwork should not be used per NPFA 77 (Recommended Practice on Static Electricity).
Is it better to have air vents on the floor or ceiling?
Ceiling and floor vents are equally as efficient, but floor vents can be slightly more efficient by providing less resistance to airflow. Ceiling-mounted vents generally have better cooling potential, whereas floor vents typically provide greater heat transfer.
Why are AC vents on the floor?
Floor ducts are effective because they deliver heated air at floor level. The heat then rises and continues to warm the rest of the room. Floor vents are typically used in homes where the furnace is in a basement or the ducts (the piping from the furnace) travel through an underground crawlspace.
Can you run ductwork under concrete?
Placing any return-air ductwork under the concrete slab is not recommended, since this will tend to draw radon into the ductwork and distribute it around the house. If supply ductwork must pass through a subslab space, it should be seamless or sealed airtight with durable aluminum tape or duct mastic.
How do you seal a slab of ductwork?
Fill the duct register hole with the concrete and let it dry. Fill the concrete hole so it is just below the floor level about 1/16 of and inch. Next use a floor leveling compound and a drywall trowel to smooth off the filled up hole and make the hole-filler smooth with existing floor. Then you are done.
What is the best location for HVAC ducts?
Air Ducts Near the Ceiling Are Most Effective
One of the most important things to be aware of when deciding on vent placement in your new home is that typically, air ducts placed near or within the ceiling are the most effective option in terms of energy efficiency.
How much does it cost to move an air vent?
The national average materials cost to move an exhaust vent is $79.69 per vent, with a range between $74.56 to $84.82. The total price for labor and materials per vent is $493.59, coming in between $448.77 to $538.41. Your actual price will depend on your location, job size, conditions and finish options you choose.
Can Return air vents be in the floor?
An air return vent is part of the HVAC system. Return vents are usually larger than heat registers and can generally be found close to the ground or in the floor in older homes or on a wall close to a ceiling in newer homes.
Can you run ductwork underground?
Underground duct systems are often chosen for aesthetic reasons and to save space in building interiors. When spiral duct is going to be installed underground, many special considerations need to be made in how it is designed, manufactured and installed in order for it to perform well in its submerged environment.
Are transite ducts safe?
While it’s cementious, transite ducts or even transite pipe used for heating flue vents is a potential asbestos hazard in buildings. Transite pipe typically contains about 15% to 25% asbestos fibers, typically fibrous chrysotile asbestos.
What is sub slab ductwork?
Sub-slab ductwork refers to HVAC ducts that run beneath the concrete floor in the basement or lowest level of your home. If you have sub-slab ductwork, you will have registers coming out from the floor in the basement, as shown in the images below.
Do slab homes have cold floors?
A: Cold concrete floors are a rather common problem, and there are several approaches to warming them up. A few are expensive or not practical for some homes. One of the most-recommended systems requires digging a trench around the outside of the slab to below the frost line, which in some climates can be several feet.
Can you use PVC pipe for HVAC duct?
PVC is durable and not prone to corrosion or denting, which makes it a good option for ductwork. Because it resists moisture, PVC is preferred when you install ductwork directly beneath the floor in a building with no crawl space.
Which plastic piping type may be used as an under slab hot air duct?
For a house built on a concrete slab, PVC ductwork is a preferable option for being placed directly beneath a floor. And as mentioned above, PVC material protects against moisture-related corrosion that can occur at the floor level.
What is PVS duct?
PVS spiral pipe is formed from a coil of metal into a rigid PVC tube with a 4-ply spiral lockseam. It has a smooth interior for low friction loss with the grooved seam entirely on the outside. This pipe has a resistance to crushing approximately 2 1/2 times that of longitudinal lockseam.
