Joseph Frederick started this business in 1947 with one truck, a willingness to work hard, and a sense of integrity. Today, four generations later, we are proud to say that the name Joseph Frederick & Sons means the best in residential and lite commercial air conditioning, electrical systems, heating and plumbing. In 2008, Joseph Frederick and Sons launched our Bath and Kitchen Renovation department. The core values on which our family’s business was first built remain its cornerstone – our sense of integrity, dependability, and quality of workmanship has withstood the test of time. We are proud to be five-time recipients of the Carrier President’s Award, 2014 Best of Delaware Plumbers, Customer Service Award from the Family Owned Business Awards, and Super Service Award recipient from Angie’s List.
Our service technicians, sales department, and customer service representatives are a part of our family, sharing our family values and high standards of quality.

We employ NATE-certified installation and service technicians, which means we provide our customers with the very best service possible.
