Serving the Rio Grande Valley from one location soon became difficult as the distance between the western and southern end of the valley is over 115 miles. A third Johnstone Supply location was established with the goal of serving the southern part of the Rio Grande Valley including the tourist town of South Padre Island as well as the growing manufacturing sector straddling the US/Mexico border.

Target Customer - School districts, residential contractors

At Johnstone Supply, South Texas we take pride in building custom solutions for your business while also finding the best products and services the HVAC industry has to offer.
