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. Ensuring you pick quality materials that work well within your space will help ensure your heating and cooling is more effective, and that your ductwork will last as long as possible. Picking a quality professional to install your ductwork is also important. You can get more help and information, or schedule a test of your ductwork, by calling O.C. McDonald at 408-295-2182

Can Custom Duct Work Be Done To Fit My Building?

The building that your business occupies for years can prove to your customers that you are here to stay. But what happens when you experience growing pains? Many times a building simply no longer provides what you need. So, now you have some decisions to make. In most cases, a new building is out of the question so you must look deeply into what your needs actually are and compare this list to the existing space and what it could provide in a new configuration.

  • Historically, office space is easy to deal with.
  • However, the comfort level, efficiency and safety of the newly configured space all need to be addressed. When a building is initially designed, the systems tend to be somewhat over-engineered allowing for future expansion and unfortunately a bit less efficiency.
  • In the case of the HVAC system, Rooftop units are easily upgraded to proved additional heating and cooling.
  • In the case of larger buildings with mechanical rooms designated for HVAC equipment, the room and equipment can be reconfigured to meet current needs. Air handling units, pumps and other system components could be upgraded, many times using the existing units by simply increasing capacity. A larger fan motor can provide additional air moving capacity. A pump with a larger motor or even just a differently designed impeller can provide additional water for heating and cooling.

Getting the increased air flow to where you need it!

Upgrading the mechanical room or Rooftop units is all well and good but what about the requirements of the newly reconfigured space? You can assume that the existing ductwork will not be sufficient to handle the new air delivery requirements. Most times, these air delivery requirements are dictated by law for various industries. For example, a laboratory has very different requirements from an office space.

Your HVAC system helps keep the air clean and tempered in your work environment. By law, there are different requirements for “number of air changes per minute” in a space. This keeps the air fresher by venting a portion of the air to atmosphere and replacing it with fresh air.

Custom duct work is a large part of the building renovation process. If you find yourself in this situation kindly give us a call and we will help you through the process. Ready to get started? Call us today at 408-295-2182

What All Can Custom Sheet Metal Be Used For?

When it comes to architectural projects, one of the most commonly used materials is custom sheet metal. Sheet metal is a component that is easily fabricated and adapted to countless uses both in residential and commercial construction projects. From the mailboxes in a residential neighborhood to the air ducts in a commercially designed building, the presence and versatility of custom sheet metal is undeniable when it comes to today’s tried and true construction practices.

The residential and commercial uses of sheet metal have large areas of overlap, including the aforementioned air conditioning ducts and cooling systems as well as lighting fixtures (both for exclusively functional purposes but also custom aesthetic fixtures too). However, lets dive a little deeper into the applications of sheet metal within the home.

Residential Applications of Sheet Metal

Sheet metal can be hiding many places you wouldn’t normally expect to find it within your home, which means it’s doing the job it’s designed for: remaining functional while also blending in with the look and feel you’ve strived to achieve within your home. From custom flooring or siding to backsplash in your kitchen or bathroom, sheet metal can be tastefully implemented anywhere.

The kitchen can be one of the most common places for sheet metal because it can easily be used for stovepipes or stove hoods, or it can even be used to make food vats or bins, but that’s more often seen within commercial applications such as in a restaurant or cafeteria setting.

When it comes to other outdoor residential uses, sheet metal is often used to construct various types of fencing enclosures as well. The uses for sheet metal really are boundless and can include:

  • Awnings and canopies
  • Gutters and other roof draining equipment
  • Coal chutes
  • Guardrails

Sheet metal can be manufactured in either flat pieces or coils depending on the fabrication process and the needs of the client. While the material has increased in popularity in architecture and construction projects in recent years, it has also seen widespread use in electronic fields and in fields such as the manufacture of military-grade weapons and equipment.

Whether you’re in the market for something simple like a custom sheet metal sign for your business in need of a more hefty air conditioning system makeover, don’t hesitate to call us at (408) 295-2182 to chat about your options today!

What is a Design and Build Contractor?

In the traditional design-bid-build model used in the construction industry, the owner hires a designer on one side and a contractor on the other. Once the design phase is complete, they will invite bids from contractors for the actual construction of the final design.

Design and build is another type of contract that has become popular of late. In this type of contract, the project design and construction is undertaken by the same entity. Instead of 3 parties (owner-designer-contractor), there are only 2 entities involved.

In many cases, a design and build contractor is a general contractor who also leads the project design with a professional architect or engineer. Some design and build firms have professionals from both sides – design and construction. Other general contractors employ architects or designers to provide design services in-house, so to speak. In some cases, a design firm may partner with a construction firm for a specific project or time frame. Many such contracts allow the owner to take the design plans and go elsewhere for actual construction.

Advantages of Hiring a Design and Build Contractor

  • There are quite a few benefits in using design-build contracts for projects: The owner has to deal with only a single contract and one firm. There is no back and forth between the owner, designer, and contractor to haggle over details, costs, and schedules.
  • It saves a lot of time. The contractor doesn’t have to wait for the architect to complete the design before starting construction. For a small project, design and construction can commence at the same time. A larger project can be divided into phases with the design and construction of each phase happening simultaneously.
  • It allows the contractor and specialty subcontractors to propose better solutions to specific elements during the design stage itself. They don’t have to wait until construction begins to make changes.

That’s not to say there are no drawbacks. Sometimes, the contractor may cut corners (design-wise) to complete the project on time or within budget. They may also make design decisions in areas they have no experience with. However, the pros outweigh the cons for the most part. It’s no surprise that the number of design and build contracts has been trending upward in the last few decades. They’re used in many countries as they reduce the risks for owners and completion time of projects. If you’re starting a new construction project or remodeling an existing building, call us at 408-295-2182 for an estimate.

What is Fabricated Sheet Metal Used For in HVAC?

Fabricated sheet metal is commonly used in the ductwork of HVAC systems. Traditional ductwork is installed in commercial and industrial buildings for the heating and cooling systems. Sometimes, however, the regular metal ductwork must be routed in odd ways, due to various obstacles in the path. Longer piping would be added to get the metal fittings and tubes installed to go around all those barriers.

Due to the odd routing of all the ductwork, the HVAC system would ultimately have to run harder to heat or cool the building properly, because it has to run the heat through a long set of pipes. For an HVAC unit to run efficiently, fabricated sheet metal would be utilized to run around the obstacles for a more direct path from the heating/cooling system to the air vents.

Fabricated sheet metal enables one to bend, and turn the metal to the desired shape, so it will fit much like a jigsaw puzzle in the areas you want them to. This would eliminate the need for all those extra pipes and fittings that only succeed in using more energy to run the HVAC system. Also, by using more customizable ductwork, like the sheet metal, you’re prolonging the life of your unit, because it’s not working harder to heat or cool your space.

How Does Fabricated Sheet Metal Have Advantage Over Regular HVAC Ductwork?

We’ve already discussed the fact that sheet metal is more customizable when it comes to installing the ductwork for a building. They work perfectly for fitting into what seems like an impossible spot for regular pipes. The places that fabricated sheet metal fittings work best are:

  • Around Sharp corners
  • Behind pipes
  • In tight, cramped spaces

When using only traditional HVAC ducts, one would have to install an intricate system of pipes to avoid the places where you can’t fit regular ductwork. Now, it’s much easier when you can get someone to fabricate ducts using sheet metal. The pipings and fitting would be cut and shaped precisely to your specifications.

Installing the fabricated pieces of ductwork helps the HVAC unit run in the most efficient way possible for any commercial or industrial building. Finding a shop that can fabricate sheet metal accurately isn’t always easy. If you’re looking to get some ductwork customized for your building or space, give us a call at 408-295-2182. Our skilled professionals can fabricate your ductwork for whatever specifications you need, and we can also install them if you want.

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.

How Quickly Can Ductwork Fabrication Be Done

When adding a new unit or expanding the additional system, ductwork replacement may be necessary. The process requires careful planning and coordination, so this alone could affect how long a system takes to build. Ductwork fabrication can completed in a matter of days depending on several factors.

Factors affecting the amount of time it takes to complete a system

Design of system-The design of the system is a factor. A more complex design may require more planning and labor. Intricate planning may be required if there are efficiency requirements that must be made. Repairs are almost unavoidable whenever a system is being upgraded. There may be multiple temperature controls that have to be incorporated into the design, which affects complexity of the overall system. If additional supply ductworks are needed than originally required, then the size of the system is affected.

Size of the project-The size of the project may vary. For example, there may be multiple stories to account for in the planning, which could affect the amount of labor that could be required. The square footage of each room affects the length of the project.

Improvement or replacement-If the system upgrade involves simply replacing the existing unit with a similar one, then there will be little changes to the design in most cases. This means that ductwork may need moderate improvements to resolve leaks or vulnerable areas.

Quality of existing ductwork-If the ductwork is aging and failing in multiple areas, then the ductwork has to be replaced. If there are energy efficiency concerns, then the ductwork should be replaced.

Permitting-Agencies may affect the timeline. The permit application may take longer to process if working with a particular agency. The duct installation project timeline could be affected if there are any delays in processing the application.

Accessibility of the ductwork-If the ductwork isn’t accessible, then the project will take longer to complete. The ductwork can be replaced quickly if it is very accessible.

How long does it take to install a ductwork?

The ductwork project takes between 1 to 4 days. The ductwork is mostly impacted by the size of the project. If there are no unexpected challenges, then the system will take only a few days to install. In some cases, the installation can be completed in one day.

New ductwork may be required if a new HVAC system is being installed. Multiple variables affecting the timeline of the project such as the design of the system and the size of the project can also affect the overall cost of the system. Most installation projects can be completed in a matter of days.

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

Will New Ductwork Improve Efficiency in an HVAC Unit Of a Facility?

Heating and cooling are a big part of your energy bill, and HVAC ducts are a major source of energy loss through leaks and lack of insulation. As much as 20 percent of your energy loss can be recovered by improving the efficiency of your HVAC unit. Look at your monthly energy bill, and extrapolate 20 percent of that over the next 10 years. Can you afford not to have new ductwork?

If you’re fortunate, your HVAC ductwork may last up to 10 to 15 years before it starts to deteriorate. If your ductwork has never been replaced in the past 10 years, you shouldn’t be surprised if your energy bills start to rise unexpectedly. You may even experience problems in less than 10 years, depending on how reliable your previous installer was.

Poor HVAC ductwork not only reveals itself in your power bill, but also in poor air quality. If your facility’s air has begun to smell stale, the health of people who live and work there may be affected. By restoring your HVAC unit to its original air circulation parameters, you’ll improve health and morale. By delivering more oxygen, new ductwork can improve efficiency by improving your efficiency and the efficiency of those you share your environment with.

Ways to Determine if You Need New Ductwork

Here are simple tests you can make to see if your ductwork is beginning to deteriorate:

  • Physically trace the ductwork through crawl spaces, looking for holes, tears, or disconnected joints.
  • Feel if the air flow and temperature remains constant throughout the rooms; a variation means you’ve got a leak.
  • Contact a mechanical contractor who specializes in HVAC and have your ductwork tested with a duct blower.

These tests will identify leaks, but what about energy losses through poor insulation? If your HVAC ductwork has developed leaks, then it’s likely the insulation is beginning to degrade as well. Again, a mechanical contractor specializing in HVAC can help you determine if that is the case.
