Service Line Air & Heat provides custom sheet metal fabrication in Mont Belvieu, TX. Precision cutting, bending & forming for residential, commercial & industrial projects.
The Barbers Hill salt dome and surrounding petrochemical corridor create aggressive corrosion conditions that destroy standard sheet metal within months—coastal humidity, salt spray, and industrial air chemistry demand custom fabrication from the ground up. We've been fabricating custom ductwork, enclosures, and transitions right here in Chambers County since 2022, and we know what coastal humidity and petrochemical exposure do to metal components that weren't designed for it.
Custom sheet metal fabrication solves what off-the-shelf components simply can't address. Unique dimensions, non-standard configurations, and applications where fit and finish directly affect system performance all require tailored solutions. Service Line Air & Heat provides custom metal solutions for diverse industry needs across Mont Belvieu, from residential HVAC ductwork to commercial transitions and industrial enclosures.
Mont Belvieu's economy is anchored by energy infrastructure, petrochemical operations, and a surge of new residential construction along the Barbers Hill corridor. Each sector demands something different from a fabrication shop. Energy-adjacent facilities need components that resist corrosion in chemically active air. New-build subdivisions like the Riceland Community and Heights of Barbers Hill by Meritage Homes require custom ductwork sized to match precise load calculations — not pulled from a catalog. We address those challenges with metalwork designed for the job at hand.
Custom sheet metal offers versatility. It extends well beyond ductwork. Architectural transitions, equipment plenums, custom registers, and specialty enclosures are all within scope. If your project has a design requirement that a standard part won't satisfy, that's exactly where we work best.
Our services support local contractors, builders, and facility managers who need a fabrication partner — not just a supplier. Construction HVAC projects across the Barbers Hill area regularly call for custom components that match architect drawings to the inch. We deliver that precision.
Four years serving Mont Belvieu and surrounding Chambers County has given us a clear picture of what local projects actually require. That's not a long history — it's a focused one, built entirely in this market since 2022.
The industries here are specific. Petrochemical and LPG-adjacent facilities near the Eagle Pointe area need metalwork that accounts for airborne chemical exposure. Healthcare facilities like those near Memorial Hermann require precision enclosures and transitions that meet strict installation standards. Residential builders pushing new phases in communities like Retreat at Barber's Hill need a fabrication partner who can turn around custom duct sections without stalling a framing crew.
We understand those distinctions.
Our commitment to precision means every component meets the specification you provided — not an approximation of it. That matters most when a misfit piece holds up a mechanical rough-in or forces a field workaround that compromises system efficiency. Get it right the first time. That's the standard we hold ourselves to on every Mont Belvieu project.
Questions about scope or process? Our FAQ page covers common fabrication questions, or reach out directly for a project-specific conversation.
Every quote starts with a conversation. We discuss dimensions, application, material preferences, and timeline. No guesswork, no generic pricing grids.
Transparent pricing means you know what you're getting and what it costs before fabrication begins. For commercial or industrial projects with complex requirements, we'll walk through the scope in detail so there are no surprises at delivery.

Standard ductwork and fittings are made in common sizes, but most homes have at least one spot where the geometry just doesn't match — an angled ceiling, a tight utility closet, or an addition that was built after the original system. Custom sheet metal fabrication lets a technician measure the exact space and cut metal to fit it precisely, so airflow isn't restricted by a makeshift adapter.
A properly fitted piece also seals better, which matters a lot in a humid climate where a small gap can let warm, moist air into your duct system and reduce efficiency all summer long.
Mont Belvieu, TX summers regularly push into the upper 80s and 90s with humidity hovering around 77%, which means metal components inside unconditioned attic spaces expand and contract significantly throughout the day. Low-quality or poorly fitted sheet metal can develop small gaps at seams over time, letting conditioned air escape and humid outside air creep in.
Custom-fabricated pieces are cut to exact dimensions and finished with proper seams and fasteners, so they hold their shape and seal better through repeated thermal cycling than generic off-the-shelf sections that were never sized for your specific layout.
Yes — uneven airflow is often caused by undersized or oversized duct branches rather than the HVAC unit itself. A technician can measure static pressure and airflow in each room, then fabricate a custom transition, reducer, or plenum box sized to balance the system. This is more precise than inserting dampers alone and doesn't create unnecessary resistance in the ductwork.
Homes in Mont Belvieu with additions or converted garages especially benefit from this approach, since those spaces were rarely included in the original duct design and often end up either too hot or too cold compared to the rest of the house.
Simpler pieces — straight duct sections, basic elbows, and standard end caps — are often cut and formed in a shop ahead of time using measurements taken during an initial visit. More complex work, like a custom plenum that has to fit around existing framing or a transition connecting two different duct sizes at an odd angle, is usually finished on-site where the technician can test-fit and adjust before final installation.
Service Line Air & Heat handles both approaches depending on what the job requires, so the fabricated piece fits correctly the first time rather than needing field modifications that can compromise the seal.
