Born in 2002
Grant and Leticia Willis founded Willis Mechanical in 2002 . They leveraged their skills and experience to form a new kind of mechanical contracting company. A company that puts customers first, treats employees well, and holds the highest standards for our work.
They got started quickly, buying their first trucks to serve their first customers. The focus was always on building relationships. Starting with zero customers is a daunting task.
When they were given the opportunity to over-deliver and delight the client, they didn’t hesitate.
Today, we are still working for that first client which we met back in 2002.
Willis Mechanical provides outstanding customer service and superior quality to our customers, performing safely, within budget, and with on-time delivery.
The company rewards its employees for their integrity, loyalty, and creativity by providing career opportunities, training and education, and a challenging environment.
Our commitment to our customers and employees will result in profitable long-term growth for Willis Mechanical.
What began in 2002 as Grant and Leticia Willis’s vision for a customer-first mechanical contracting company has grown into a proud second-generation family business. In 2025, ownership officially transitioned to 100% second-generation leadership, continuing the tradition of excellence, integrity, and unwavering commitment to Atlanta’s commercial clients.
Today, we deliver the same high standards in HVAC, plumbing, piping, and chiller services that have kept our very first customer with us since day one. We are not backed by private equity, corporations, or outside investors. We do not answer to shareholders or holding companies. We are, and always have been, a family business, focused on doing what is right for our customers, our employees, and our community.
We’re not just a contractor; we’re a family dedicated to building lasting relationships and driving long-term success for every business we serve.
