Established in 1977, Sun Mechanical Contracting, Inc. is an Arizona-based full service mechanical contracting and construction firm with offices/plant facilities in Tucson and Phoenix.  We are committed to continuous improvement and customer satisfaction. With a reputation of excellence for over three decades, we design, engineer, fabricate and install projects using a collective experience and level of expertise that few mechanical contractors have.

Sun employs over 300 skilled tradesmen in the field and has the physical and financial stability to complete jobs on time, on budget and with the highest level of quality and performance.


Sun Mechanical, headquartered in Tucson, Arizona, has offices in Phoenix and Casa Grande as well. Through any of our offices our clients have access to – and benefit from – our extensive resources in manpower, materials, product fabrication and manufacturing. Each of our offices also provides full 3D Modeling capabilities.

The top priority at Sun Mechanical is to provide a quality product in the safest possible environment for our clients and employees. For that reason, we have developed and established our own comprehensive internal program called Quality Assurance/Quality Control. The primary purpose of QAQC is to lay a strong foundation of specific commitments, values, guidelines and job requirements that will create and maintain a clear, consistent culture of quality and safety throughout our company. The ultimate goal is to provide our clients with the highest quality materials, equipment and workmanship consistent with their project specifications and design. This, in turn, will ensure that all mechanical systems installed or manufactured by Sun Mechanical meet or exceed the client's expectations.

Sun Mechanical Contracting, Inc is proud to announce that it is the recipient of the NAWIC Safety Excellence Award--2011 Construction Company. The region includes Arizona, Utah, Wyoming, Colorado, New Mexico and West Texas.
