Our journey

Built on Hard Work and Trust

Service One began in 1987 with a simple goal: provide honest, dependable HVAC service to local families. Over three decades, Alan Davis built the company on strong values, hard work, and genuine care for customers. Today, alongside his son Bryce, that same commitment continues, combining experience with modern solutions while staying true to the family principles that started it all.

Our team keeps homes comfortable year-round across Keller, Southlake, and the DFW Metroplex, focused on honest service, reliable solutions, and treating every customer with respect. We believe in doing the job right the first time, every time.
