Harry Clark Plumbing and Heating Inc. is a well-established HVAC and plumbing service provider proudly serving the Oakland and Berkeley, California communities. With a rich history tracing back to its founder, Harry Clark, the company has evolved significantly while maintaining a steadfast commitment to exceptional service.

In 2020, the company strategically divided into two specialized entities: Harry Clark Plumbing & Sewer and Harry Clark Heating & Air Conditioning, operating side-by-side from their Oakland locations at 3026 and 3040 Broadway.
