    Derek and his team (3 people total) are very friendly, professional and timely. We installed two split A/C units in our main living spaces and they have been working exceptionally well, no problems thus far. The team works very quickly, so they are in and out of your home quickly, not wasting any of your time. We highly recommend their services if you are in the market for having air conditioning installed in your home.

    Derek (the owner) and his guys installed my Central AC unit, great service and good clean work he even let me know that having a larger AC unit is not better (cause I had the thinking the bigger the better), he let me know that when you get bigger AC it would create problems like mold, and he saved me money $$$! I recommend them to anyone looking for AC in Hawaii.. right now its to dam hot here not to have AC..

    We decided to move forward and Derek's team was in our driveway the next day and worked so efficiently to knock it out.

    Highly, highly recommended. Larry has installed 6 spit ACs for different rooms of my home over the…read morepast 10 years. When he did his first install, I was so impressed with the clean piping and shroud covers that I paid him to fix my previous installers for a cleaner look. Aside from the installs, Air Solutions has performed numerous routine cleanings that have kept the units operational. When older units started breaking, Larry came over, demonstrated the failing parts and provided reasonable solutions. I appreciate the quotes and work performed are always trustworthy. Hard to find a company like this one to perform work on your home.

Larry (the owner) stopped by after I contacted him and provided me with an estimate. I contacted other companies and ASH was the lowest - with stellar reviews. We scheduled for replacement the following week and Larry and his son, Dylan, did an amazing job. They ran into a couple of issues: 1. Dylan, through a freak accident, injured his toe nail, but was back to work shortly afterwards. Amazing work ethic and attitude! 2. There was an issue installing the unit downstairs as my wall was not plumb. But, Larry McGiver'ed it and made it work. They also installed the shroud covers plumb & true with Larry advising me that the covers would not cover some of the old paint. Not an issue for me as I appreciate a professional installation and a bit of touch up paint is minor. Larry is friendly, knowledgeable, and professional. I know that he takes pride in his work after speaking with him and seeing the results of their work. I recommend Air Solutions Hawaii without reservation! And, I love supporting small businesses. Thank you Larry and Dylan!

    I had an excellent experience with APV Construction Corporation when upgrading my central AC…read moresystem. My old unit from 1999 had been out of commission for years, and when I started shopping around for a replacement, it felt like most companies either weren't interested in doing a central AC reinstall or were quick to push me toward a split system. While splits are cheaper, I didn't want new condensers blocking my walkway, and I preferred reusing my existing ductwork and electrical setup. APV was the standout. They gave me a straightforward and reasonable quote for restoring the central AC--only slightly more than the split-system options I was being offered, especially considering how expensive other companies have become. They also partner with Hawaii Energy, which helped me get an additional discount. That made the decision easy. From the moment Jordan provided the quote, the entire process moved fast. Lyrissa handled the scheduling and had the installation booked within a couple of weeks. In total, everything was completed in right around two weeks from quote to installation, which was impressive. Mark, Trenton, and Juel arrived right before Thanksgiving to do the install. They were prompt, professional, and efficient. My home is wonderfully cool again, and we enjoyed a very comfortable Thanksgiving because of them. I'm genuinely pleased with the entire experience and highly recommend APV to anyone looking to restore or upgrade their AC system.

    Just in time for this summer heat…read more Last year my split system AC started to leak on the inside of our house, and finally after 27 years she no longer worked I researched best brands, models and companies before reaching out to APB construction. Out of all the yelp and google reviews this one stood out to me. I inquired to get a quote and received a call same day to go over pricing. The call was the perfect balance of inquiry, salesman ship but most importantly true aloha spirit. I got other quotes all similar in pricing but didn't have the same experience I did with my initial quote call. Because of the customer experience I chose this company. I reached out to inquire about scheduling an install and the hard part was done for me, this company truly made the whole process seem less. They removed my old system and quickly installed my new one all in the same day. We had gone without the AC for a few months and it was so nice to finally be cooling off the house. I will definitely be recommending this company to both family and friends when they inquire on what company helped my house get back to its igloo status in this summer heat.

Myra (office manager) was very sweet and got back to my quote and questions very fast, explained to me whats was included with maintenence cleaning my split AC indoor and outdoor units and was able schedule maintenance with my day time preference in 2 days. They partner with Hawaii Energy and gave me $150 off instant rebate for maintenance cleaning both my indoor and outdoor units, which made their rate very competitive compared to all the other company quotes. Cleaning day I was notified in advance when the technicians were on their way. The 2 technicians were professional and came on time with their company KK air conditioning truck and van. They were both very nice and patient with my 2 curious toddlers and dogs. The cleaning work was phenomenal, and both indoor and outdoor units were squeaky clean when they were done. 3.5% fee for credit card payment and received an email invoice receipt. Im very grateful to the KK air conditioning team and will definitely be calling them again. Thank you KK Air Conditioning!

    DO NOT HIRE KK Air Conditioning!!!…read more Save yourself from the stress, unprofessionalism and unethical practices!!! We paid KK Air Conditioning (Kent Muramoto the owner) $53,000+ to install central air conditioning -- 2 new units -- in our home in Waianae and have had nothing but trouble with company and the owner. - Consistent rattling of the intake air vent for over a year and they've done nothing but bandaid fixes until we demanded they permanently fix them instead of using cheap double sided tape to rig the system - 1.5 yrs into having the units i've gotten a HUGE leak that's in my master closet and master bedroom. (most recent situation.) - I had to hire another industry professional to take care of the leak problem that Kent Muramoto (the owner) is NOT able to fix. - We've had to get multiple outside technicians to review the problem and they all said it was an installation and maintenance issue that cause these leaks - In a final attempt to try and fix the issue, Kent Muramoto has made the problem worse and now i'm left with a BROKEN AND INOPERABLE system, AGAIN. I've been left with nothing but stress and ongoing issues ever since this company stepped into my home. Kent Muramoto has been very UNPROFESSIONAL AND UNETHICAL in regards to the issues we've experienced.

After reading Calvin's excellent reviews on Yelp, we decided to give him a call -- and he came out the same day to assess the situation. His wife, Nicole, was incredibly professional, friendly, and easy to communicate with. Later that same day, Calvin returned after finishing another job. He immediately impressed us with his knowledge of the AC systems. Instead of pushing for expensive replacements, he recommended maintenance where possible, which saved us a significant amount of money. The estimate he provided was much lower than we had expected -- a welcome surprise. Calvin ended up replacing two of the units and performing maintenance on the remaining three -- all by himself. His attention to detail and excellent customer service made the entire experience smooth and stress-free. Calvin is down-to-earth, approachable, and clearly takes pride in his work. We're extremely satisfied and highly recommend his services!
