FIRST RATE CUSTOMER SERVICE! From my very first contact with Duane, he was lightning quick in responding to all my inquiries/ flexible with scheduling and super knowledgeable on the various system configurations to maximize my $spend. He helped in the selection process for my split system which consisted of two large condensers and 4 indoor evaporators. Special shout out as well to tech's Trent and Chad who went above and beyond to resolve a wire short issue that unexpectedly occurred.
They troubleshooted the system till they found the cause and then returned the following day to finalize and ensure all was functioning properly. if you're considering installing a split or any AC system and are on the fence as to who your contractor will be, LOOK NO FURTHER! CALL AC UNLIMITED! You won't be disappointed. These guys are first rate all the way.

Needed a window a/c unit installed in our new condo. Called a few places in the middle of the China flu pandemic and these folks were the only ones to call back. With things backlogged due to the flu it was a few weeks before they were able to come out for an estimate. They came out on the date and within their 30 min window. The crew was friendly and did a great job of fitting the unit into the window.
They showed me what they were doing and how to remove it because we are planning on new windows in the fall. The crew installed it quickly and cleaned up afterwards. They did a great job and would certainly use them again for all my a/c needs.

We can say only good things about our experiences with Duane and his crew. They have now installed split units at two different houses for us. They had the first house which was 2800 square feet completed in ONE day! We were so impressed that we called them when we moved to do our new home. This was more of a challenge for them due to working around other utilities already installed in the house. But, they figured out an ingenious work-around, and over a year later we have not had a problem.
Some reviews are not good--sounds like they may be stretched thin due to being in great demand. All of the employees were professional and courteous to us. We even recommended them to our realtor, and she made a note of the company and their phone number.

Long story short, it was frustrating just to coordinate someone coming out to give us a quote. It's been over a week since they came and we still never got the quote. At this point, why would we even bother with them if they can't provide good service for a QUOTE request?

Very pleased with the maintenance and cleaning of our Split Mitsubishi units. Excellent customer service from calling in scheduling maintenance to the maintenance and cleaning provided by Alex. Also Air Conditioning Unlimited is a participating contractor of the Hawaii Energy Air Conditioning Tune-up Rebate. Thank you very much for the awesome service!

I tried contacting this company multiple times regarding an ac tune up and I haven't even received a call back from them. Their company name is listed under the Hawaii state energy website as a contractor and I'm not sure why they can't give a courtesy call. I wouldn't bother with this company if they can't perform the most basic customer service.
