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. Randy at RMI did a fantastic job installing our AC.

I'm a return customer to RMI Mechanical due to the excellent service received on an earlier Mitsubishi split AC install for my living room that was very reasonable. Maybe not the lowest price in town but you will get excellent service for the money. Randy is easy to talk to and can accommodate your special split AC installation requirements for a very satisfactory end result. I think I'm more on the particular side of most customers and he was able to accommodate. I met with Randy at his office to go over some details of the installation and we were able to work to a mutual solution for

Randy and his team were great. Installing air conditioning is a big expense, but we believe our money was very well spent with RMI Mechanical. Their work was done on time, as scheduled, quickly, and neatly. Randy gave us good advice about the equipment we needed and how best to use the units once they were installed. He answered all our questions (even the silly ones) with patience, good humor, and helpful information. If we ever need to replace or repair our new system, we will definitely call RMI as our first choice.

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.

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.
