Our History

Founded In 1960

Cassidy Family Portrait

Our Beginning

John C. Cassidy, Sr. “Jack” settled in Palm Beach County to build a family and a future.

Jack started John C. Cassidy Air Conditioning in 1960 on the dining room table of the home he shared with his wife, Mercedes, and their five children. Jack set the bar high for both himself and his new company, instilling a lofty corporate philosophy to always be honest and conduct business with integrity.

Jack’s unwavering commitment to maintaining the highest level of customer service and creating an enjoyable work environment for his employees led the company to become part of a remarkable metropolitan expansion and the largest independent family-owned air conditioning contractor in South Florida.

Our Values

Soon after, the John C. Cassidy slogan, “your first and last name in air conditioning,” began to have a familiar ring for many area home and business owners. Generations of customers have come to know that every employee, repair, installation, and business transaction comes with the wholesome heritage of the Cassidy family behind it. You won’t find a more reputable, courteous, knowledgeable, or professional air conditioning company employee in your home, business, or on the telephone.

Since 1960, the company has grown significantly, moving from the dining room table to our first location on Fern Street in West Palm Beach to our current location in Riviera Beach. The reins have since been passed down from Jack to his son, John C. Cassidy Jr. “John”. Today, John is joined by a talented team of managers, service technicians, installation technicians, salespeople, and administrators, most of whom have been with the company for more than 10 years and some as long as 40.

Every John C. Cassidy team member is committed to offering the highest quality products and service at the fairest price possible, and 100 percent customer satisfaction every time. The legacy lives on, becoming even more stringent as comfort control technology advances and the demand for ethical, knowledgeable, and highly skilled air conditioning professionals increases.

That is why our company logo is simply our name and is displayed on our fleet of vehicles so recognizable throughout the region. John C. Cassidy Air Conditioning & Plumbing conducts business as if John C. Cassidy, Sr. were along on every repair, every installation, and every sale. It’s the way he intended. It’s our way. The Cassidy Way.
