About NTD Mechanical
NTD Mechanical opened in May 2001 on Merritt Drive in Garland and has spent more than two decades growing into one of the most trusted mechanical contractors in the DFW metroplex. With an A+ BBB rating and 4.9 stars across 18 customer reviews, the company serves commercial and public-sector clients throughout North Texas, handling new construction, tenant finish, and design-build projects from their Garland headquarters. The firm carries a $35 million bonding capacity, positioning it for public works, government, education, and large-scale private projects across the region.
What separates NTD Mechanical from other commercial contractors is the depth of its specialized credentials. The team holds LEED construction experience, qualified geothermal installer certification, and a reputation as one of DFW's top Daikin VRV/VRF system installers. Clients seeking energy-efficient retrofits or complex variable-refrigerant-flow systems can access a contractor with both the factory relationships and the field expertise to install and service these sophisticated systems. From hydronic piping to comprehensive indoor air quality solutions, NTD builds mechanical systems designed to meet modern efficiency standards.
