The History of SMS

Sam Mangham is a native Texan with roots all the way back to the Civil War. Sam loves the state of Texas and has dedicated his life to serving its residents’ heating and cooling needs for decades.

Right out of high school in the mid-90s, Sam began working in the sheet metal fabrication industry, where he learned tools that would later benefit the HVAC industry. In early 2000, Sam started working at a local HVAC company and, over the next 14 years, learned the ropes of the industry, from duct fabrication, installation, maintenance, service, and replacement.

In 2014, Sam decided it was time to jump into the HVAC/R world on his own. He began Select Mechanical Services by utilizing his experience and drive to continue growing and learning in the industry. In 2017, SMS was incorporated and has been growing strong ever since.
