5 Top-Rated Commercial Ductwork & Metal Fabrication Companies in Virginia for 2026

Lift a ceiling tile in almost any Virginia commercial building, and you will find sheet metal doing quiet, essential work. It moves conditioned air, carries grease out of kitchens, and protects equipment from the weather. When that metal is built well, nobody notices.
When it is built poorly, everyone pays.
A Berkeley Lab duct study measured what leakage costs in large commercial buildings. Adding 15% duct leakage at operating conditions raised fan power by about 25% to 35%. That is a steep penalty for metal that was not sealed well.
Fabrication quality is therefore a cost issue, not a cosmetic one. This guide compares five companies that build ductwork and custom metal products for Virginia projects. Each one publishes enough detail to evaluate, and each fits a different kind of buyer.
How we chose these five
We started with a simple question. Which firms clearly state what they fabricate, in which materials, and for whom?
Every company here describes its own shop, product range, or fabrication process on its website. We favored firms that name materials, sizes, or equipment over those offering only general claims. We also covered a spread of buyers, from restaurant owners to mechanical contractors.
We did not invent ratings or review scores. Where a company publishes numbers, we report them as the company's own claims. Where it stays silent on gauge, pressure class, or certifications, we say so.
Treat this list as a starting point for your own vetting. Request references, shop drawings, and written lead times from any firm you shortlist.

1. VA Commercial Repair Solutions: The Shenandoah Valley's In-House Fabrication and Repair Shop
Full transparency: VA Commercial Repair Solutions is our company, so we are not neutral judges. We included our own shop because its fabrication work fits this list. We describe it as candidly as the others.
VA Commercial Repair Solutions is a Class A mechanical and electrical contractor based in Fishersville. It serves commercial and industrial facilities, not homeowners. Fabrication is one part of a wider offer that includes HVAC, refrigeration, kitchen equipment, boilers, and electrical work.

That mix is the main reason it belongs here. The company builds the metal, installs it, and then services it later. You deal with one contractor from the first drawing to the first repair call.
What they fabricate
The company says it fabricates and installs commercial ductwork in-house instead of subcontracting it. That includes balancing for new systems. Kitchens get custom stainless steel Type 1 and Type 2 exhaust hoods.
Its metal fabrication page lists a broader range. Products include sheet metal, spiral duct, supports, backsplashes, and enclosures. The list also covers ladders, platforms, railings, rooftop catwalks, conveyor rails, steel stairs, and docks.
Welding capability backs that up. The company's industrial repair page lists MIG and TIG welding on steel, stainless steel, and aluminum.
Strengths and trade-offs
Pros:
- Fabrication, installation, and repair sit under one roof, so accountability is simple.
- A live person answers calls 24/7/365, with no voicemail.
- It holds a Class A license, plus S.W.A.M. and eVA certifications for public-sector bidding.
- It says it services everything it installs.
Cons:
- Its coverage centers on Charlottesville, Harrisonburg, Staunton, Waynesboro, and Lexington.
- The ductwork page does not publish gauges, pressure classes, or seam types.
- Pages describe project work, not a wholesale or ship-only duct program.
Pricing and terms
Pricing is not published. Installation quotes are free, and there is no service call fee when repair work is performed. The company says new HVAC, hood, and exhaust fan installations carry one year of free labor.
Who relies on them
The customer base is restaurants, breweries, food processors, and facility managers across central Virginia and the Valley. The company reports more than 20,000 satisfied clients. That figure is self-reported, so ask for references that match your project type.
2. Vortex Metal Manufacturing: Richmond's Rectangular and Spiral Duct Manufacturer
Vortex Metal Manufacturing operates from 1855 Boulevard West in Richmond. The footer dates the company to 2012. Its pitch is manufacturing at volume, not field installation.
What they fabricate
Rectangular duct and fittings can be made in any size to specification. Spiral duct and fittings run from 4 inches to 52 inches in diameter, in 10-foot lengths. Spiral can be cut to any length.
The material list is wider than most. It includes galvanized steel, galvannealed steel, stainless steel, aluminum, and black iron. Rectangular duct can ship loose or knocked down to save freight space.
The company says its products meet or exceed ASHRAE, SMACNA, and SPIDA standards. Those are its own claims. Ask for the construction standard in writing.
Strengths and trade-offs
Pros:
- A broad range of materials, including stainless and black iron for demanding applications.
- A clear diameter range for spiral products.
- Separate ordering paths for cut sheets and for takeoffs and bid lists.
Cons:
- The site publishes no gauge, pressure class, or lead-time figures. It says only "quick lead times."
- The pages reviewed describe manufacturing and shipping, not field installation.
Pricing and ordering
Pricing is not posted. Estimating handles takeoffs, PDF links, and bid lists, and a separate contact handles cut-sheet orders. Expect quotes to reflect material, size, and quantity.
Who relies on them
Vortex says it serves customers in Virginia, North Carolina, Washington, D.C., and Maryland. It also reaches other East Coast buyers. The target buyer is a mechanical contractor or distributor, not an end-user building owner.
3. Howell's Heating & Air: Ashland's Retrofit and Grease Duct Specialist
Howell's Heating & Air has served Richmond and central Virginia since 1969. The shop sits at 11216 Air Park Road in Ashland. The company holds a Class A license and works in both commercial and residential markets.
For this list, the interest is its fabrication page. It treats custom ductwork as a service in its own right.
What they fabricate
The company builds custom sheet metal ductwork for new and retrofit work. It makes transitions, elbows, and fittings for tight or unusual spaces. Welded or flanged assemblies handle heavy-duty commercial applications.
Prefabricated assemblies shorten on-site installation time. Fire-rated assemblies are also listed. Materials include galvanized, stainless, or aluminum sheet metal, depending on the specification.
Its FAQ also mentions grease duct fabrication that follows NFPA 96 requirements. If your project includes a kitchen exhaust, confirm that standard and the inspection process before you order.
Strengths and trade-offs
Pros:
- Retrofit expertise, including custom parts for older buildings with unusual geometry.
- Stated turnaround: simple ductwork often finishes within days, and complex assemblies take one to two weeks.
- Commercial maintenance agreements and 24/7 emergency service, so one company can fabricate and service.
Cons:
- The site does not list specific machinery or gauge ranges.
- Rush fabrication is only "sometimes possible" and may change the price.
- Commercial work shares the website with residential service plans.
Pricing and terms
Pricing is quoted by project. The company says rush work may affect pricing. Ask whether prefabricated assemblies are priced separately from field-built runs.
Who relies on them
The company lists office parks, healthcare facilities, retail centers, educational campuses, and industrial operations. Those buyers value fit and schedule more than raw volume. A retrofit in an older Richmond building is the sweet spot.
4. R.S. Harritan & Company: Richmond's Industrial Sheet Metal and Plate Fabricator
R.S. Harritan & Company bills itself as "Virginia's Premier Source for Complex Pipe and Sheet Metal Fabrication." It is part of EMCOR Group, a publicly traded contractor. The sheet metal operation runs from a 24,000-square-foot facility in Richmond.
This is an industrial shop first. Its work goes well beyond standard commercial ductwork.
What they fabricate
Standard ductwork is fabricated on a computer-driven plasma cutter. The software cuts and labels straight duct and fittings, including rectangular, round, and oval shapes. The company says automated layout nearly eliminates waste.
The shop also shears, forms, rolls, and breaks material from 28 gauge up to quarter-inch plate. Stainless is available up to quarter-inch. Specialty items include conveyor fabrication, prefabricated housings, heat recovery systems, and platforms.
Its site also lists unusual products. Examples include tobacco transfer chutes, concrete conveying piping, and chip conveying systems for paper mills. Pipe fabrication, structural steel, and millwright services round out the offer.
Strengths and trade-offs
Pros:
- Plate-thickness capability that few ductwork shops publish.
- Automated cutting and fitting labeling, which supports tight schedules.
- A broad skilled workforce, including fabricators, pipefitters, ironworkers, and millwrights.
Cons:
- The focus is industrial, so small restaurant or office jobs may not fit its model.
- The pages reviewed list no certifications or founding year.
- Pricing is project-based, with no published rates.
Who relies on them
Its published markets include power companies, water treatment plants, and manufacturing facilities. HVAC contractors also use its ductwork output. Choose this shop when the job involves heavy gauge, plate, or process equipment.
5. ADJ Sheet Metal: A Maryland Fabricator Serving Richmond and Northern Virginia
ADJ Sheet Metal is based in White Plains, Maryland, about 30 miles south of Washington. We include it because it lists Richmond, Alexandria, Arlington, Loudoun County, and Manassas among its service areas. Its size is the draw.
The company reports over 250 employees and dates itself to 2002. Its banner also claims "100+ years of sheet metal experience," which seems to describe combined experience. Ask what that figure means.
What they fabricate
ADJ makes spiral lock-seam and rectangular ductwork in a wide range of sizes. It describes its seams as nearly airtight, with smooth interiors and lower airflow resistance than rectangular duct. Fittings and couplers can be customized.
The shop also builds custom HVAC cabinets, sheet metal fittings, and electrical enclosures. Materials include cold and hot rolled steel, galvanized steel, stainless steel, aluminum, copper, magnesium, and zinc.
Two facilities support the work. The main plant is 45,000 square feet, with a 57,000-square-foot addition. A separate spiral shop sits nearby.
Strengths and trade-offs
Pros:
- Large capacity, with two fabrication sites and a fully automated shop.
- Estimating and BIM coordination for design-assist projects.
- A very wide material list that includes copper and zinc.
Cons:
- It is based out of state, so freight and delivery timing deserve attention.
- The pages reviewed list no certifications, gauges, or pressure classes.
- Kitchen exhaust work is not mentioned.
Pricing and terms
Pricing is project-based. The site invites quotes through its contact form, with PDF uploads up to 50 megabytes. Expect estimates built from drawings and takeoffs.
Who relies on them
The company lists arenas, colleges and universities, and federal and government buildings. It also handles tenant renovations and private construction. Its natural customer is a prime contractor with a large, well-documented scope.
How to evaluate a fabricator before you sign
The five companies above differ widely, so a consistent checklist helps. Start with standards.
SMACNA, the Sheet Metal and Air Conditioning Contractors' National Association, represents 3,500 signatory firms. It publishes SMACNA's duct construction standards for metal and flexible duct. Ask any shop which standard it builds to.
Next, ask about gauge, seam type, and pressure class. Duct that runs at higher pressure needs heavier construction and tighter sealing. A shop that cannot answer clearly is a shop to question.
Then ask about sealing and testing. Leakage drives energy cost, as the study cited earlier showed. A fabricator that tests or documents leakage tells you it takes the number seriously.
For kitchens, add a code check. Grease duct and hood work fall under fire and mechanical codes, and your inspector will check them. Our restaurant kitchen design checklist walks through hood, fire suppression, and refrigeration planning for Virginia openings.
Finally, get lead times in writing. A beautifully built duct system that arrives three weeks late can stall every trade behind it. Ask about rush fees before you need one.
Common mistakes when buying fabricated metal
Even a good shop cannot rescue a vague specification. A few mistakes show up again and again.
The first is buying on price alone. Two quotes for the same duct can differ because one assumes lighter gauge or fewer sealed seams. Compare scope line by line before you compare totals.
The second is skipping shop drawings. Drawings catch conflicts with beams, pipes, and cable trays before metal is cut. Fixing a clash on paper costs far less than fixing it above a finished ceiling.
The third is ignoring access. Dampers and cleanout doors need room for service. A duct that cannot be reached cannot be maintained.
The fourth is forgetting who services the system afterward. A fabricator that never visits the site cannot tell you why a run is noisy. A contractor that installs and services its own work learns from every callback.
Frequently asked questions
What is the difference between a fabricator and a contractor?
A fabricator builds the metal parts, often in a shop. A contractor installs, services, and warrants the finished system. Some firms, like those in this guide, do both, while others focus on one side.
Should I choose stainless steel or galvanized duct?
Galvanized steel suits most dry, conditioned-air applications. Stainless is common where moisture, corrosion, or sanitation matters, such as kitchens, labs, and food plants. Your engineer should set the material in the specification.
How long does custom ductwork take?
It depends on size and complexity. One Virginia contractor on this list says simple ductwork often finishes within days. It says complex assemblies take one to two weeks, so confirm dates for your own project.
Does duct leakage really affect operating cost?
Yes. The Berkeley Lab study cited earlier found that 15% leakage raised fan power by about 25% to 35%. Sealing and testing protect both comfort and budget.
Can one company fabricate and install?
Yes. Several firms here do both, which simplifies accountability. The trade-off is that a pure manufacturer may offer deeper material choices or volume capacity.
Conclusion: matching the fabricator to the job
The right choice depends on your project. Need fabrication, installation, and 24/7 repair from one contractor? VA Commercial Repair Solutions fits restaurants, breweries, and Valley facilities.
For duct in volume, Vortex Metal Manufacturing is built for that role. Howell's Heating & Air suits retrofit work in older central Virginia buildings.
R.S. Harritan & Company is the pick for heavy gauge, plate, and industrial fabrication. ADJ Sheet Metal makes sense for large institutional scopes where capacity and BIM coordination matter most.
