The material is typically galvanized steel, aluminum, or stainless steel, depending on the application. Professional installation of ductwork, including air vents, return air grilles, diffusers, and dampers. Proper installation is vital for efficient air distribution. Installing insulation on sheet metal ducts to prevent heat loss or gain, reduce noise, and improve the energy efficiency of the HVAC system.

Typically done every 4-6 years by physically inspecting the operation of each damper to ensure it opens and closes freely. Fusible links are replaced as part of the inspection. Correct air flow direction and air changes in operating rooms, CATH Labs, inpatient nursing homes, radiology, diagnostic and treatment areas.  [![Contact Us](https://hubspot-no-cache-na2-prod.s3.amazonaws.com/cta/default/45705506/interactive-171408455953.png)](https://www.dmcmechanicalcontracting.com/hs/cta/wi/redirect?encryptedPayload=AVxigLJ1Oitdrbwe5slxvv2CK5%2FOC7OGJKBEfKSA3cAd0RMwKrZcEFy65gqEkemeuTi%2FBm0m3egvkE1wdx9pbUxDBucq0qAp%2FZj2tyvssXYQWrYlxtB8dA60iiFKkcN4jtHn4cpw86mmkfGHwUYsQfa1gHZ%2BioacmPkwRq%2B8FIyWWxKsi%2BKuIj7%2BoHl7WnKswZoTxsU9hQ%3D%3D&webInteractiveContentId=171408455953&portalId=45705506&hsLang=en) ### Get in Touch Contact us for any questions or inquiries about our services.  137 Windy Meadows Dr Schertz, TX 78154 Phone: (210) 437-1388 **TACLA55973C / M41385 / TECL38328** [www.tdlr.texas.gov](http://www.tdlr.texas.gov) *Regulated by the Department of Licensing and Regulation, PO Box 12157, Austin, Texas 78711 (800) 803 9202 www.tdlr.texas.gov* *Clint Dawson M41385, TSBPE, 7915 Cameron Road., Austin, TX 78754, (512) 936-5200* © 2026 Copyright © DMC Mechanical Contracting LLC Return to top
