What That Means for You

Stephens was selected as a Mitsubishi Diamond Contractor because we place value on a team that has the highest level of certification, training, and hands-on expertise. That means you’ll benefit from our quality of work and product knowledge, not to mention the excellent customer service we’re known for.

Highly Trained Specialists

In order to be given the status of Diamond Contractor, one must attend Mitsubishi Electric’s training classes at approved centers across the United States. After undergoing extensive training and being able to demonstrate product knowledge, the title is authorized. Diamond Contractors must demonstrate their continued commitment to serving customers in order to renew their status.

Exceptional Customer Service

Diamond Contractors are HVAC specialists with years of experience in the industry and are experts at recommending the right system for your home to maximize energy efficiency. They must sign a Code of Conduct agreement that focuses on providing superior customer service and support before, during, and after your equipment purchase.

Quality Parts

Purchasing equipment from a Diamond Contractor ensures you get genuine parts when repairing or replacing a component. Diamond Contractors get ongoing product, maintenance, and installation training directly from Mitsubishi, and they service all the Mitsubishi Electric products they sell and are supported from the factory.

Industry-Leading Warranty

Mitsubishi Electric provides an industry-leading 12-year factory warranty protection to back up its unmatched performance and product quality. The only way to get a full 12-year warranty is by purchasing and installing your Mitsubishi Electric product from an authorized Diamond Contractor.

Real Reviews From Happy Customers

Sort reviews

I worked with several contractors to diagnose and fix my AC Pro mini split units. Hundreds of dollars later and hours of frustration baking in the heat because of a non-working AC, Stephens was able to properly diagnose and fix my AC within days of calling them. Oscar, Omar, and Pancho are the best technicians with a wealth of knowledge. I called them for several different issues, and they have always been reliable, consistent, professional, friendly, and good at what they do! I know if I have a problem with my AC they'll get the job done. I am hard to please and id give them 10 stars if I could. Thank you Stephens Plumbing for doing an A++++ job!
