Take The Guesswork Out Of HVAC Installation With A Diamond Contractor®

You’ve done your homework, and you’re sold on the benefits of a Mitsubishi Electric ductless solution vs traditional heating and cooling options. The next step—finding a reputable contractor—is the place where many people hesitate.

How can you ensure a company, or contractor, is familiar with the technology and can provide a satisfactory result? If you’ve spent any time renovating, you can understand the apprehension behind this question. The right contractor can mean the difference between a tidy, professional job and a grout-filled trip down the installation rabbit hole.

To help make the decision process easier, Mitsubishi Electric created a certification program for contractors, where professionals are kept up to date on the latest technology and installation practices. The Diamond level is the highest accreditation available through Mitsubishi Electric’s multi-stage training program.

So why hire a Diamond Contractor®?

Customer Education and Free Consultation

... Product knowledge and education are two areas where Mitsubishi Electric certified Diamond Contractors® really excel over the competition.

While you may have your heart set on a particular system, it never hurts to schedule a free, in-home consultation first. A Diamond Contractor® can survey your floor plan and help you pick a system that’s best suited to the size and layout of your home.

Large and small houses have vastly different temperature-control needs, and these factors can impact whether you choose a single- or multi-room unit. Finding the right fit, and accurately quoting a cost estimate, requires intimate knowledge of the system. This is one of the areas in which Diamond Contractors® excel.

Diamond Contractors® are also up to date on the latest environmental programs and rebates that your product may qualify for. In other words, they can help save you even more money, when lower energy consumption is factored into the equation.

Quick, Expert Installation

... In an experienced Diamond Contractor’s® hands, the turnaround time for a ductless install can be as quick as one or two days, depending on the size of the project.

Although ductless technology has been around for a number of years, it’s still a relatively new phenomenon in North America, where forced-air units had previously dominated. To understand the ins and outs of this next-generation product, a certain level of expertise is required.

Correctly sizing and mounting an indoor air handler—the visible, cooling- or heating-control interface—is vital to the unit’s operation, for example. This is where a Diamond Contractor’s® specialized training comes in. The difference between a passable and perfect install often comes down to your contractor’s level of expertise.

Extended Warranty

An extended warranty plan is one of the many perks of hiring a Diamond Contractor®. In the case of an M-Series ductless, the five-year limited warranty plan on the compressor and parts is upgraded to a seven-year warranty when you choose a Diamond Contractor®. See the product warranty statement for more details.


To get the most out of your Mitsubishi Electric cooling and heating system, consider choosing a Diamond Contractor® for installation. You can get in touch with a local expert by using the ZIP code search, or call 1-800-433-4822 to speak with a customer care representative.
