About Us

Serving South Florida

John C. Cassidy, Sr. settled in Palm Beach County to build a family and a future. From Day 1, he 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. Mr. Cassidy, Senior’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.


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.


Today, John C. Cassidy, Jr. is joined by a talented team of managers, service technicians, installation technicians, salespeople and administrators, most of whom have been with the company 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.
