Custom Sheet Metal Solutions for Your HVAC Needs

At Mountain View Air Conditioning & Heating LLC, our sheet metal fabrication capabilities extend far beyond standard ductwork installations. As the longest-running locally owned and operated HVAC company in Cochise County, we’ve invested heavily in state-of-the-art fabrication equipment and training to ensure every component we create meets exact specifications for your heating and cooling systems. Our fabrication shop handles everything from custom ductwork transitions to specialized ventilation components, allowing us to solve unique airflow challenges that off-the-shelf products simply cannot address.

The precision required in sheet metal fabrication directly impacts your system’s efficiency and performance. When ducts are properly sized and fabricated, your HVAC system operates at peak efficiency, reducing energy consumption by up to 30% compared to poorly fitted or generic ductwork. Our technicians use computer-aided design software to map out exact measurements before cutting a single piece of metal, ensuring perfect fits that minimize air leakage and maximize comfort throughout your home or business.

Advanced Fabrication Techniques and Materials

Our fabrication process begins with selecting the appropriate gauge and type of metal for each specific application. We primarily work with galvanized steel ranging from 30-gauge to 18-gauge thickness, depending on the duct size and pressure requirements. For commercial applications requiring higher durability, we fabricate using 16-gauge steel that can withstand industrial-level air pressure and volume. Each piece undergoes precise cutting using our plasma cutting systems, followed by forming on our brake press machines that can handle sheets up to 10 feet in length.

The joining methods we employ make a significant difference in system longevity and performance. We utilize Pittsburgh seams, snap-lock connections, and standing S-cleat joints depending on the application requirements. These mechanical joining techniques create stronger, more reliable connections than simple screwed joints, reducing the likelihood of separation or air leakage over time. For high-pressure systems, we incorporate welded joints and reinforced corners that can handle static pressures exceeding 10 inches of water column.

Residential and Commercial Applications

In residential settings throughout Hereford, Sierra Vista, Benson, Bisbee, Tombstone, Sonoita & Douglas, AZ, our custom fabrication services address numerous challenges that standard ductwork cannot solve. We regularly fabricate custom return air plenums that maximize airflow while fitting within tight mechanical spaces. Our team creates specialized transitions for connecting different sized ducts, ensuring smooth airflow without turbulence that can create noise and reduce efficiency. We also fabricate custom registers and grilles that match unique architectural features while maintaining proper air distribution patterns.

Commercial projects demand even greater precision and durability in sheet metal fabrication. We produce heavy-duty exhaust hoods for restaurants, specialized ventilation systems for medical facilities, and high-velocity ductwork for industrial applications. Our fabrication capabilities include creating custom louvers, dampers, and access doors that integrate seamlessly with existing building management systems. As an exclusive Carrier and Bryant Dealer, we ensure all our custom fabricated components work perfectly with these premium HVAC systems.

Quality Control and Installation Excellence

Every piece of fabricated sheet metal leaving our shop undergoes rigorous quality control inspection. We check dimensions against original specifications, test joint integrity, and verify that all edges are properly hemmed to prevent injury during installation. Our fabrication team maintains tolerances within 1/16 of an inch, ensuring perfect fits that reduce installation time and improve system performance. This attention to detail is why we confidently offer free second opinions, knowing our fabrication quality speaks for itself.

Installation of custom fabricated components requires expertise that comes from our 39 years of experience serving the Southern Arizona. Our installation teams understand how to properly support custom ductwork to prevent sagging, how to seal connections to achieve less than 5% leakage rates, and how to insulate fabricated components to prevent condensation and energy loss. We use mastic sealants and reinforced tape at all joints, creating airtight systems that maintain efficiency for decades.

Benefits of Professional Sheet Metal Fabrication

• Energy Efficiency: Custom-fit ductwork reduces air leakage by up to 90% compared to poorly fitted systems
• Noise Reduction: Properly fabricated ducts eliminate whistling and rattling sounds common with generic installations
• Improved Air Quality: Smooth, sealed surfaces prevent dust and allergen accumulation within the system
• System Longevity: Professional fabrication extends HVAC system life by reducing strain on equipment
• Space Optimization: Custom pieces maximize usable space while maintaining proper airflow

Our commitment to excellence in sheet metal fabrication ensures your HVAC system operates at peak performance while providing years of reliable service throughout your property.
