Our Story
The company’s legacy began in 1988, when Harry Anderson—a determined Midwesterner with $40 and a passion for hands-on work—moved to San Diego. After putting himself through HVAC school and working nights at a climate control R&D facility, Harry built his career through roles at Sunn Aire, Hilton Hotels, and Carl’s Jr. He eventually launched Reliable & Dependable (RAD) Refrigeration, and in 1991, acquired San Diego Refrigeration.
Over the next three decades, the company steadily expanded—growing its team, its footprint, and its reputation for high-quality service. In 2022, the business officially became San Diego Refrigeration, Inc.
Today, our team continues to thrive by doing what we’ve always done best: solving problems, delivering results with precision, and building lasting relationships through hard work, hustle, and heart.

“This team has always shown up with grit, pride, and a genuine care for our clients. We know their names, we know their systems, and we take it personally when they call. As SDR continues to grow, I’m focused on making sure we never lose that—our people-first mindset is what sets us apart, and that’s not changing.”
“San Diego Refrigeration has a legacy built on hard work, trust, and excellence. As we look to the future, our goal is to keep raising the bar while staying grounded in the values that matter most—our people, our clients, and our commitment to doing things right. I’m proud to carry that legacy forward with the same attention to detail and heart that got us here.”
