About Us

While Comfort Systems USA Mid South currently operates as an independent operating entity with our parent company Comfort Systems USA, it was originally established in 1963 as H&M Plumbing Company and focused primarily on multi-family projects. The company expanded its operations to include more mainstream mechanical projects in markets such as Healthcare, Education, Retail, and Office Buildings. Comfort Systems USA purchased H&M Plumbing Company in 1998, when it became H&M Mechanical, Inc. In 2016, H&M Mechanical, Inc merged with Capital Refrigeration, another Comfort Systems USA Company and, in 2018, officially changed its name to Comfort Systems USA Mid South, Inc.

We provide customers with high-performance mechanical systems and services along with delivering high-quality work at reasonable costs. The majority of our projects are with repeat customers using collaborative, innovative and team approach processes.

Comfort Systems USA Mid South is the premier and preferred leader in building and service provider for HVAC, mechanical, electrical and plumbing systems.
