About Us

Three Generations of Commitment

Using the basic guidelines of good customer service, hard work, and pride, Irvin “Mac” McWilliams retired from the US Navy and put his skills to work. He traded his sailor’s hat for a technician hat when he started McWilliams Appliance and Refrigeration in 1974. A few years later, his son, Irvin McWilliams, Jr. joined the business and Mac changed the name to McWilliams and Son Heating and Air Conditioning. Following in Mac’s footsteps, Irvin began working as a helper while still in high school and eventually became President of the company. Trey McWilliams, Irvin’s son, and the 3rd generation, has followed in their example. Since he was a little boy, Trey has worked side by side with his father and grandfather, wearing multiple hats from tool helper, to service technician and eventually, Founder & Board Member.

All 3 generations have sacrificed blood, sweat, and tears working long days to serve our customers through hot summers and chilly winters. Their legacy continues to evolve as McWilliams and Son, Inc. added plumbing in 2021, and in 2022, launched the first-ever Home Services Academy, offering paid training and expanding opportunities for careers in the trades. As the Founder & Board Member of Blue Cardinal Home Services Group, Trey continues to honor his grandfather’s legacy by offering contractors opportunities to expand and invest in their teams and communities.
