Our History
In 1960, John C. Cassidy Sr. settled in the Palm Beaches to build a family and a future. His company became part of a remarkable metropolitan expansion. Mr. Cassidy's philosophy of honesty, integrity and a sincere commitment to his customers and his employees, led John C. Cassidy Air Conditioning to become the largest independent, family owned air conditioning contractor in the South Florida area.
Creating and maintaining a better environment for our customers and employees along with a strong commitment to the highest levels of service is the reason that John C. Cassidy has become "your first and last name in air conditioning" in the Palm Beaches.
With a reputation for quality products and unequalled service, Cassidy customers not only value the comfort the Cassidy team brings to their environment, but the comfort and peace of mind they have with the heritage of the Cassidy family behind them. The organization is made up of people you can feel secure welcoming into your home or place of business. Generations of Cassidy customers can attest to that.
The business is operated today by John C. Cassidy Jr. He is joined by a team that has served the customers of John C. Cassidy for an average of over 20 years. Members of the service, sales, engineering, construction and administrative departments take pride in the company's deeply rooted tradition of offering quality products and service at a fair price. Each member of the Cassidy staff is committed to 100% customer satisfaction.
