Our Story

Bob & Tom Deroche, Co-Owners

williams-service-company-york-paWilliams Service Company was opened in 1979 by Mr. Gary Williams in East York. The Deroche brothers, Tom and Bob bought Williams Service Company in January of 1991. Tom was currently employed at C.C. Kottcamp as a Service Tech while Bob the younger brother worked as a public accountant at Philip R. Friedman & Associates LLC. When Mr. Williams suddenly passed away, they decided that this would be an excellent opportunity to purchase the company with the help of their father.

The brothers had a vision that today is a thriving business due to their family core values. Their tenacity and knowledge have kept the brothers moving in the direction of unparalleled growth. Today, they are a leader in providing HVAC & Commercial Refrigeration. They have created a diverse customer
base with our local residential community, and a wide range of commercial and industrial accounts scaling from the smallest to the largest facilities. Over the years, their footprint continues to expand and grow into Harrisburg, Lancaster, Hanover, and the surrounding areas.

Williams Service Company’s primary business is solving HVAC problems. They specialize in new installations, replacement, or repair of existing systems. Each and every Technician is highly trained and EPA certified with technical expertise in Residential, Commercial, Industrial Refrigeration & Installation meeting a wide range of HVAC needs 24/7. WSC analyzes and chooses the best equipment to determine the optimal system for the required area, and installs & calibrates the equipment for a smooth transition that will sync with the new changes. Tom says, “Big or small, we are specialized to do it all!”

As Williams Service Company continues to grow, one thing remains constant, its team of people. Bob says, “We are fortunate to have a GREAT team of people who are dedicated to excellence in every aspect of our business. When you call Williams Service Company you will receive the best possible service experience.” We look forward to servicing you!
