Company History: Built on a Better Principle

Founder Jason Braun started Apex after a career in HVAC showed him an industry often prioritizing profit over people.

Fourteen years later, that core philosophy still guides every service call and installation. From a single service van, Apex has grown into a respected local leader by consistently putting people first.

Jason Braun's hands-on experience shapes the company culture. He's built a team that shares his belief that customers are more than just a transaction. This local, owner-operated business is actively involved in the community, including support for St. Jude Children's Research Hospital.
