“If you need air conditioning, then this is the company to use. They're knowledgeable, fast, courteous, and reliable. I have had four split air units installed, 3 bedrooms and a living room, and it was quickly and professionally installed and any problems I had since then have been resolved promptly, with the owner, Randy, coming to the site and making sure I was completely satisfied. Highly recommend!”

-James L., Ewa Beach

“We got quotes from several different Mitsubishi split AC vendors and we chose RMI. There pricing was very good and Randy gave me a ton of options on installation. We are very happy with the installation and customer service. Randy even called me the next day to make sure I liked the install. I would highly recommend RMI if you are looking for a Mitsubishi AC vendor.”

-Ryan M., Aiea

“Randy at RMI did a fantastic job installing our AC. He was prompt and courteous. But what I valued most about his service was the respect he had for my time and property. He answered all my questions pertaining to the installation and gave excellent advice from beginning to end. I've dealt with many contractors and Randy at RMI has earned my highest respect. I would not hesitate to use RMI again. As the 5 stars indicate, they are highly recommended. Quality service and an excellent product...That is what I received from RMI."
