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 are Sheet Metal Ducts Made?

There are basically two types of ductwork. The first type, which is also the most frequently used, is rigid and often made of galvanized sheet metal. The other type is flexible and is usually constructed with plastic. This blog will take a deeper look at the former type and how exactly this ducting is constructed.

When metal ductwork is installed in a building, it is custom fitted so that it fits exactly into the dimensions in the floor, ceiling or wall. There is a number of ducting parts that are commonly built that are then assembled and modified at the build site. It is kind of like putting together a kid’s construction set. A variety of pieces are provided and then pieced together to make a functioning air flow system. The common ducting shapes include:

  • Straight round pipe
  • Straight oval pipe
  • Half sheet rectangular pipe
  • 90 degree adjustable elbow
  • X, Y and Z connector pieces

Machinery Does the Fabricating Job

Sheet metal, the raw material for rigid ducting, can be cut and shaped by hand, but this is a difficult task. Automated machines do the work of cutting, folding and grooving to create all the different components needed to assemble a new ducting network.

Rectangular metal ducts are built by putting two pieces of bent sheeting together. The flat pieces of metal are first cut to the desired size with a cutting machine or plasma cutter. Then, another machine folds the sharp edges inward. Thirdly, the sheet is shaped into an L or a tube. Most rectangular ducting is made to standard sizes, but the machines can be adjusted to create the ducting in custom sizes.

Round metal duct, also known as spiral pipes, are made with a different process. At the start of the process, the sheet metal is put into a machine that coils it. The machine fuses the edges together to make the pipe air-tight. The pipe is then passed to the next processing step where it is cut to the desired length.

The ductwork in your building is a critical component for the safe and healthy use of the facility. Give us a call today at 408-295-2182 to learn more about the ventilation services that we provide.

What Are the Different Types of Sheet Metal Duct Designs?

Sheet metal is an excellent choice for heating and cooling equipment because it enhances the performance of duct design components. Not only are sheet metal components easy to install, but they also provide energy efficiency, strength, and durability, as they can withstand high temperatures and environmental elements.

Materials Used in Sheet Metal

Galvanized Mild Steel

One of the most popular duct designs for buildings is based on galvanized mild steel with a rust-resistant zinc coating. This design is widely used because it can be easily customized and it provides sufficient protection against air loss, helping lower energy bills. The smooth quality of galvanized steel reduces the airflow compared with other duct materials. It also prevents the growth of mold and fungus.

Aluminum Duct-work

Due to its light weight and resistance to corrosion, aluminum has become a popular choice for duct-work. The material is reliable for both indoor and outdoor use in the following industries:

  • automotive
  • construction
  • printing
  • mining

Major advantages to aluminum are that it’s easy to install and can be easily bent to fit any shape.

Stainless Steel

Providing the same amount of strength as aluminum or galvanized steel, stainless steel is another effective type of sheet metal for budget-conscious building owners. It also resists corrosion and moisture, which is why it’s a top choice among food processing plants and sites with large industrialized construction. Swimming pools also work well with stainless steel applications, which add attractive aesthetics to a facility.

Custom Designs

An experienced fabrication shop has the tools and skills to create custom designs for clients with unique building layouts. Any type of duct can be designed with computer-aided design (CAD) software. The ideal duct system takes into account how much heating and cooling is needed in each room in terms of BTU per hour. You then need to determine the materials, the size of the system and select the right tools.

Like any HVAC equipment, the ducting system must be installed properly to avoid common maintenance problems. Keeping the duct clean and having it inspected by a professional every year are keys to extending its longevity.

Conclusion

Understanding the various types of sheet metal duct designs will help you determine the best solution for your needs. Make sure your design allows air distribution throughout a building while maintaining good air quality and energy efficiency. Call one of our counselors today at 408-295-2182.

How Much Does It Cost To Replace Air Ducts?

If you own commercial property, air conditioning maintenance and repair is often essential. Sometimes it becomes necessary to replace the duct work. Ductwork wears out after 10 to 15 years of use. Leaking ductwork can pollute the indoor air quality, cause the heating and cooling to be ineffective, and can even cause leakage around the vents. If you notice any of the symptoms of failing ductwork or have ductwork that is over 15 years old, it is time to start looking to getting your properties duct work replaced.

Including labor and materials, it can be $35 to $55 per linear foot to replace ductwork. This price can change based upon the type of building you have, the number of vents, and the type of duct work you use, the need for return air drops, and other unique features your building may have.

Just the ducting itself can cost $16-$19 per ten linear feet, but different types of ductwork have different b benefits and costs.

Price Break Down of Ducting Types (all per linear foot)
• Flexible Non-Metallic: $1-$2
• Flexible Aluminum: $1-$4
• Sheet Metal: $1.50-$6
• Fiberglass Duct Board- $4.50-$6

In addition to the cost of ducting, there are other necessary materials. The ducting may require joints or need elbows, which can cost between $5 and $25 each. Ductwork also requires foil sealing tape, which costs around $35 for every roll of 60 feet. Duct fans start at $30 and then increase in price. Vents can cost $6 and up, depending on size and how decorative they are. Labor is usually billed between $50-$70 per hour. Of course, necessary permits will also have to be pulled and paid for.

Keep in mind that while there are lower cost options available, you want to make sure to choose the materials that will be the longest lasting and fit best in your building.

The Advantages of Fabricating New Sheet Metal for Your HVAC System

Another few years have passed and now it’s time for you to perform maintenance on your HVAC system. It takes time and money, and then you have to do it all again in the next few years. You should instead consider replacing the material in your HVAC system with sheet metal. Though thin, sheet metal has proven to be strong, efficient, and cost-effective. Whether you are a facilitation manager for a large company or responsible for new construction projects, sheet metal is highly recommended for ventilation ducts.

Sheet metal can withstand large amounts of pressure along with the harsh weathers ranging from frigid to scorching. It is lighter than other material used for ventilation ducts. Regardless, it’s the custom fabrication of the sheet metal that is specifically tailored for your business. Sheet metal is cost- and time-effective because it’s simpler to make. The material isn’t imported from across the sea. Not only does it save money for HVAC contractors, but it saves on your company’s energy bills in the long run.

The Efficiency of Sheet Metal for Your HVAC System

There are a number of ways that sheet metal is economical for your company:

  • custom fabrication reduces air leaks
  • the relatively smaller size allows for better air volume and distribution
  • easier to manage

Sheet metal is always custom fabricated, and this is beneficial. Regular, generic-shaped air ducts are not as stable; they have a tendency to move and bend while in use. This causes air leaks. Air leaks mean that your ventilation would have to work even harder to get the air to its destination. It will stay on longer and increase your energy bill. Custom fabricated sheet metal is sealed tightly and cut to fit your building. It will not experience energy losses like normal air ducts.

Due to its smaller size and sealed design, sheet metal ducts allows air to flow through in smaller volumes. Therefore, the fresh air will make it to the designated rooms faster. These ducts simply have better control of the air volume. As a result, this is another way your HVAC systems won’t have to work as hard and saves your company money on the energy bill.

Maintenence should still be required every few years for your HVAC systems. However, sheet metal makes it easier for HVAC technicians to service. You also will not be required to have to replace it every few years. This is because custom fabricated sheet metal ducts are more durable, and is yet another money-saver.

If you’re ready to save money on your energy bill, then call us today at 408-295-2182 and inquire about sheet metal ducts for your building.

Why You Should Replace AC Ducts

When you are outside, you can breathe fresh air from all directions. In a building, you might receive the majority of your air from your air conditioning (AC) ducts. Learn why you should replace AC ducts.

Most air is a combination of many different elements, including oxygen. The dirtiest air is filled with germs, dust, smoke and other airborne contaminants. Some diseases are spread through the air.

When your workers have the freshest air with the highest percentages of oxygen, they are the most productive. They can concentrate and complete tasks faster. Here are some of the reasons for replacing AC duct work:

  • Fresh Air
  • Reduce Airborne Contaminants
  • Prevent Diseases
  • Indoor Air Quality

Do you know what is breeding in your air duct work?

Replace Air Ducts

When an athlete goes to the sideline, he gets oxygen to reinvigorate him. Fresh air can increase your workers’ productivity. They can process information faster and complete their tasks on time.

Do you want your workers to be coughing into their keyboards? This prevents them from completing their assignments. It also spreads germs and increases the chances that others will get sick too.

More sick time will lead to fewer productive hours. Airborne diseases can cause simple fatigue or lead to more serious lung problems. This is especially true during the flu season.

There are many other types of contaminants that simply make breathing more difficult. Dust can clog up the lungs. Coal mine workers eventually get “black lung” due to long periods of exposure to airborne contaminants. How do the lungs of your employees look?

As a building owner, you are not only responsible for your employees, but also guests and vendors. What do they say about your Indoor Air Quality behind your back? Do they rue visiting your establishment or leave with a hacking cough?

If you care about promoting an image of excellence, does this not extend to having superior Indoor Air Quality also? Rats, squirrels, bats and birds nest inside your air ducts. Vermin leave all sort of waste material that are then recycled into the air, you breathe.

Replacing your AC ducts can help all people breathe easier, avoid airborne diseases and work more productively. Are you convinced that your AC ducts need cleaning? If so, call us today at 408-295-2182

Saving Time and Money By Using a Professional Sheet Metal Company

When facing sheet metal projects that need to be completed on commercial or residential buildings, it isn’t uncommon to wonder if the project can be done without professional intervention. The DIY processes of sheet metal fabrication may initially seem like an effective way to save money, but many find themselves spending more in the long-run. Even with the financial aspects aside, failing to hire a reputable professional to tackle your sheet metal needs can result in safety issues and code violations as well.

Many people associate sheet metal workers with just roofing alone, but their expertise is truly expansive to say the least. Becoming certified in sheet metal fabrication requires workers to be able to:

Becoming well-trained in these areas give sheet metal workers the experience and skills necessary to successfully complete your sheet metal projects with the most cost-effective approach. They also carry licensing and insurances that are regulated on state and federal levels, giving both you and their employees the protection and accuracy that you need to get the job done. Attempting to complete these sheet metal projects on your own will not guarantee the desired result, which can end up costing you in terms of future renovations. The obligations of the sheet metal company will be listed out in their insurance policies and contracts, legally providing you with reassurance that you will get the result that you desire.

 

Safety Should Be a Central Priority

A professional sheet metal fabrication company will also have access to the proper equipment to perform any sheet metal tasks that you send their way. Attempting to complete these projects on your own without the right tools can put you and anyone else involved at immediate risk. Hiring a professional sheet metal fabrication company will give you peace of mind knowing that the projects are being completed with the necessary safety equipment, as well as the appropriate skill level.

What is Sheet Metal Fabrication?

Manufacturing any product out of metal requires sheet metal fabrication. It is the fundamental process of taking a plain sheet of metal and forming it into the shape required for a part or component part of a larger manufactured good. Companies in the computer, electronics, medical equipment, and appliance industries are common sheet metal fabrication users. They require metal fabricated parts for a wide variety of projects. Some fabricated metal components are large, such as those needed for a household appliance, while other are tiny, such as those often needed by the computer and electronics industry.

There are three methods of sheet metal fabrication: cutting, forming, and finishing. Anything constructed of or containing metal must go through one of these processes. Here is a detailed description of each:

Cutting

Cutting is just what it sounds like, the process of cutting sheet metal into smaller pieces. However, one cut does not fit all. The size and application of the fabricated part indicates which cutting process is employed. Shearing uses a cutting machine to cut large pieces of metal into smaller ones. Electrical Discharge Machining (EDM) uses an electrode spark to melt conductive materials. Abrasive cutting uses a saw to cut through the metal. Precision parts require laser cutting.

Forming

Once the metal has been cut using one of the above processes, it must be formed.

Depending on the specifications, one or more forming processes are employed. Metal can be shaped through the rolling process, which uses a roll stand to roll over the metal. Bending and forming are the methods of shaping metal by hand. If the metal requires a design, we employ the metal stamping process. When necessary, metal pieces are joined through welding.

Finishing

No metal product is ready to ship until is has gone through finishing. During this process, all rough spots and edges are made smooth. The parts are cleaned and rinsed so they are ready as soon as they are shipped.

Sheet metal fabrication requires a provider with the equipment and experience to create metal components that fit the often tight specifications of many manufacturing projects. The components must also be durable, so they support the finished product’s quality. We have provided this level of service and quality in our manufacturing division for decades. Many Silicon Valley companies have come to rely on us for fast and high-quality sheet metal parts. If you need a sheet metal fabricator, call us today (408) 295-2182
