Legacy Home Services, your local HVAC, Electrical, and Plumbing contractor, exists to return respect to the home services industry in New Braunfels. Integrity. Honor. Service. Reliability. This Home Services company will distinguish itself from others by the virtues with which we conduct every business transaction. Legacy Heating & Air Conditioning Services, LLC started in February 2013 in Founder Chad Briggs’ garage. With a passion for serving people, Chad aimed to build an organization of individuals who genuinely care for the people in the community. A servant’s attitude was paramount, prioritizing respect for the customer and building a relationship rather than treating them like a transaction. Legacy quickly outgrew the garage through its stewardship towards customers and the community. In 2018, Legacy partnered with Trane Technologies to provide the New Braunfels community with the most reputable residential equipment. In October 2022, Legacy expanded by introducing the Electrical department and rebranding as Legacy Home Services, all while maintaining its focus on serving others. And in June 2025, Legacy expanded into Plumbing to continue offering its exceptional service to more customers! Legacy devotes its energy to become the #1 choice for home services in New Braunfels through its 5-star online reputation, loyal Legacy Family Plan Membership customers, highly trained and caring Comfort Technicians, and caring team of internal support team members.
