Mitsubishi Diamond Contractor

Home> Mitsubishi Diamond Contractor


Westin Air is proud to be a Mitsubishi Diamond Contractor. What does this mean for our customers?
Diamond Contractors must complete a 2 day course with Mitsubishi, so they are well trained on the Mitsubishi product line. They must also keep up with training, as new products come to market. This assures you that you are getting good advice on product selection and the best possible installation. This all adds up to superior comfort and efficiency for the homeowner.


Diamond Contractors are nominated by their distributor, they must sign a Code of Conduct, and install a minimum of 20 systems annually.


By selecting a Diamond Contractor, you know your contractor has the knowledge and expertise to deliver the best possible customer satisfaction with your new Mitsubishi Ductless Mini Split system.


You also will receive an unprecedented 12 year parts and 12 year compressor warranty on all residential products. This is available ONLY when dealing with a Diamond Contractor.
