Meet the Team


Angela Sherman

Angela Sherman has deep roots in the commercial HVAC industry.  Her father was a consulting engineer and product designer for various air distribution and air terminal manufacturers.  By the time Angela graduated from the Georgia Institute of Technology with a bachelor’s degree in engineering, she knew she wanted to be a HVAC Manufacturer’s Representative.

After careers with both Carrier Corporation and Honeywell in various states, Angela, and her husband Steve, decided to make Houston, TX their home.  Angela has had the unique experience of working directly for Marley Cooling Towers in their factory office as well as serving as their independent representative. She and Steve opened the doors to S&S HVAC in 2007, and the rest is history.  For many in the Houston HVAC market, Angela Sherman and Marley Cooling Towers are synonyms for each other.

When Angela isn’t working, you can find her enjoying a great meal or glass of wine while planning her next international trip.

Vice President

Scott Steffen

Growing up on a family farm, Scott developed a passion for machinery and a knack for finding creative solutions to pressing issues. It was a natural fit, then, when he decided to attend Texas A&M University to study engineering. After graduation, Scott kicked-off his career in the HVAC industry, first in DFW and then the Gulf Coast. He and his wife, Meredith, have called Houston home since 2011.

Scott began working with S&S in 2017 and has been honored to have Angela Sherman as a mentor. Today he’s proud to call Angela his business partner, and he is grateful for the opportunity to continue and grow the company she & Steve started 15 years ago.

When he isn’t working, Scott enjoys getting lost in the woods/desert/mountains with Meredith and their two kids, Nora & Calvin. He relaxes by tinkering in his woodshop or busting knuckles under his El Camino. And he is so, so excited for the future.
