Custom Duct Fabrication & Installation in El Paso, TX

​

Precision Airflow Designed for the Desert Climate

Your ductwork is the backbone of your HVAC system. In the extreme heat of the Borderland, standard "off-the-shelf" ducts often fail to deliver the static pressure needed for modern cooling. If your home or business is over 30 years old, or you notice rising utility bills, it’s time for a professional evaluation.

Southwest Air Conditioning specializes in in-house custom sheet metal fabrication. Unlike competitors who outsource their ductwork, we design and build every transition, plenum, and branch in our local El Paso shop to ensure your system operates at peak performance.

​

Why New Ductwork is Crucial for Refrigerated Air Conversions

Are you switching from an evaporative (swamp) cooler to a refrigerated air system? This is the most critical time to evaluate your ducts. Because refrigerated air moves at a different velocity and pressure than evaporative cooling, using old, oversized swamp cooler ducts can lead to:

​

• Higher Energy Costs: Refrigerated air requires airtight, R-8 insulated ducting to prevent "attic heat gain."

• Frozen Coils: Restricted airflow from poorly designed ducts is the #1 cause of AC compressor failure in El Paso.

• Uneven Cooling: Avoid "hot spots" in rooms furthest from the unit with a custom-engineered layout.

​

By choosing Southwest Air Conditioning for your conversion, we can perform a Manual J Load Calculation to ensure your new custom ductwork is sized perfectly for your home’s square footage and El Paso’s high-altitude climate.

​

Signs Your Ductwork Needs Professional Attention

​

• Visible Rust or "Duct Sweating": Common in older El Paso homes with aging insulation.

• High Utility Bills: Leaky ducts can waste up to 30% of your energy before it ever reaches your living room.

• Dust & Allergies: Gaps in ductwork pull in desert dust and insulation particles from your attic.

• Noisy Vents: Whistling or banging indicates restricted airflow or poor fabrication.
