About Us

Our History

Established in 1968, we are an aggressive and energetic firm, directed by highly capable personnel, who are recognized throughout the industry for their long-standing experience in the air conditioning business, along with their individual reputations for experience & integrity.

Knowledge acquired in corporate administration, operations, engineering, construction, and project installation, provides a background with a broad scope of experience, acquired while associated for many years within the mechanical contracting industry. Past experience includes a broad scope of applications, including clean rooms, hospitals, manufacturing facilities, commercial buildings, tenant improvement, food processing, biomedical and pharmaceutical facilities. This capability along with a growing service and maintenance department, allows Graycon, Inc. to provide complete service to our many customers.

We are located in the City of Industry, California, and have an efficient layout of administrative and engineering offices, service department, sheet metal fabrication shop, piping shop and storage areas situated in an industrial area with ready access to all major freeways in the Southern California area.


Accessibility is the keynote of our offices and shops. This accessibility results in convenience and savings to service customers, clients, suppliers, and our diversified operations. Cost savings can be realized many times by a DESIGN BUILD team effort between the Owner, Architect, Engineer and Graycon by working together to simultaneously engineer and install the environmental systems for optimum efficiency, performance and economy. Project delays and loss of revenue are virtually eliminated by this practical approach, resulting in benefits to all concerned.

Graycon, Inc. is fortunate in that our personnel are fully experienced in all phases of heating, ventilating, and air conditioning for existing multi-story buildings. Full recognition is given to factors for satisfactory installation, such as: engineering and design; preparation of working drawings; realistic quotations; and nearly simultaneous fabrication and installation with minimum disturbance and maximum satisfaction to the most important tenants.
