What Can You Expect to Pay for Sheet Metal Ductwork?

Ductwork is the networking of tubes that are connected to heating, ventilation, and air conditioning (HVAC) systems and run throughout homes. The purpose of ductwork is to diffuse air from the HVAC system into homes. If you are considering installing an HVAC system within your home, you must install companion ductwork.

If your home has an existing ductwork network that is old or in poor condition, you may need to install a new ductwork system. If your ductwork has cracks, leaks, or is in poor condition, you should consider replacing your ductwork network. There are several factors that affect the cost of ductwork installation. The factors include the shape of the ducts, the length of the ducts, and the type of HVAC system that the ductwork is going to be connected to.

Ductwork Installation

In general, the installation of ductwork takes place within the attic of homes. Ductwork contractors plan and map out the lines of ductwork necessary for your home based on the lighting within your home. The ductwork is then cut and trimmed in order to fit the exact lengths needed for your space. After cutting the ductwork, joints are then attached and the ducts are connected to your HVAC system and the vents within your home.

The most common HVAC systems that require ductwork include:

  • Central air conditioning
  • Furnace heating
  • Central gas heating
  • Geothermal heating

Keep in mind that the ductwork installed for air-conditioning systems are also installed for heating systems.

Cost of Ductwork

The average cost of ductwork is $35 to $65 per linear foot, with the additional fee of labor and materials. The overall cost for ductwork within an average home ranges from $1,000 to $6,000. An average single-family home requires approximately 30 to 90 linear feet of ducting. The total specific length of ducting usually depends on a home’s particular layout. The material chosen for ductwork can vary in price. The types of ductwork and their average prices per linear foot include:

  • Flexible aluminum – $1.00 – $4.00
  • Flexible non-metallic – $1.00 – $2.00
  • Fiberglass duct board – $4.50 – $6.00
  • Sheet metal – $1.50 – $6.00

How Can You Fabricate Ductwork by Yourself?

Most homeowners hire professional technicians to repair their HVAC units. When you want to save money, you might wonder if you have what it takes to do your own ductwork.

Depending on how handy you are with a few simple tools, you could craft ductwork that might work well in your HVAC. You can fabricate your own ductwork by following these steps.

Gather the Necessary Materials

Before you make your own ductwork, you need to make sure you have the right materials and tools on hand. You should start by purchasing a piece of sheet metal that measures four by eight feet.

You also should make sure you have a table and work area that is large enough to accommodate the sheet metal. After you buy the metal and tools like a sheet metal hammer and steel ruler, you can start making ductwork for your HVAC.

Measure and Mark the Sheet Metal

Using the steel ruler, you can then start measuring and marking the metal before cutting and forming it. Place the steel ruler anywhere from 10 to 12 inches from the metal’s long edge. After lining up the ruler to the sheet metal, mark the metal at one inch in two places. Make sure the marks are two feet apart.

Then slide the ruler away from the metal’s edge until the edge of the ruler lines up at one of the one-inch marks. Locate the measurement on your ruler that corresponds with the width of the duct and then mark the metal at this point. Repeat this for one more inch.

Continue this process to measure for the height and length as well as one more measurement for the width of the duct. The last measurement should be marked at the ¼-inch mark. When you are finished marking the metal, you should have a pattern of:

  • One inch
  • Width of the duct
  • Height of the duct
  • Width of the duct
  • ¼-inch

When this pattern is in place, you are ready to put the ductwork together.

Bending the Metal

Bending and crafting the metal into ductwork requires you to use a lock former machine. Follow the measurements on the metal to bend it at each mark. You will have a ¼-inch lip on the duct when it is finished. Use a sheet metal hammer to clamp this down and lock the duct into place.

Ductwork does not have to cost you a lot of money. If you are handy with working with sheet metal, you could craft your own for your HVAC. Call us today at 408-295-2182 for more information.

Does Heating and Cooling Duct Work Take a Long Time to Install?

Ductwork is an important part of your heating and air conditioning set up. Ductwork is used for distributing air throughout your home once it has gone through the heater or air conditioner. It also sucks air back through the ducts to create equilibrium in the home. Your ductwork has a direct impact on air quality. Whether you run a warehouse or a small office, air conditioning and heating is a necessity.

Over time, ductwork can need replacing. It may need to be replaced because of a bad design that is hampering air flow, or because it is simply older. Bad ductwork can have an effect on employee productivity due to reduced air quality and/or bad air circulation. When choosing to get your ductwork replaced, time is an issue. You want your office, warehouse, store, or other business to be back up and running as quickly as possible.

What factors affect how long ductwork replacement takes?

It is hard to give a definitive timeframe for all ductwork since there are many factors that affect how long it will take to replace ductwork.

These include:

  •  Building Size
  • Number of Air Conditioning Units
  • How much redesigning is necessary for better air flow.
  • Accessibility of ductwork.
  • If the construction is new or already existing.
  • Type of ductwork.

While each item on this list plays a factor in the length of time for ductwork replacement, normally ductwork replacement takes at least a day or two for normally sized buildings. Larger buildings may take three to four days, depending on the size of course. If you have a large building with more than one air conditioning unit, that will also have an effect on the installation time.

The other major factor in time mentioned above is if ductwork is being installed in new construction or an already existing building. Ductwork installed in new construction can be done quickly because there are fewer obstacles to accessibility. New construction also offers the benefit of being able to work a new design, versus having to work within an old design and possibly find ways to improve it.

Also, ductwork types affect installation time. Industrial style sheet metal ductwork will take longer than the fiberboard styled duct working. If you are building new construction, or need your ductwork replaced in your current building, we can help you! Call us at 408-295-2182 today.
