Plumbers are almost impossible to even get a return call from on Kauai. I have called and worked with many over the 25 plus years we have been here. Some good, some very pricey, some... not so great at all. I had a 6 month issue with my solar water heater. The tank was overheating and exploding water all over my indoor lanai. I called one company and they replaced a bunch of stuff, sold me something I didn't need and after six visits, didn't fix the problem and thousands of dollars later. I was getting desperate about the flooding the tank overflow. So I called Kauai A/C & Plumbing. They came out the next day to have a look. Kimo came out and actually listened to what I had to say and what I thought it had to be - the only thing left - a fairly new tank (3 yrs old) just out of warranty. So he left after 1/2 hour. to get a quote ready. I contacted the office back about the quote. It felt on the high side to me (as I replaced the tank and plumbing three and half years ago for half the price) but I was desperate and no one else was returning calls and a few I refused to call back anyway. The appointed was made fairly quickly, within the week. The time to show up was set and they arrived on time. Kimo and Micah came and brought my new tank. In the first day they had it all hooked up and re-plumbed with a new pump, but something was off with the controller. They thought I may need a new one. I explained it was working just fine before. I explained that there were wires in the controller that may need to be hooked up, but we thought it was okay as is. I called the office and they were nice and said they would be back out in the next day, after I explained it still wasn't right. SO... Kimo kept at it. He called two solar suppliers looking for an answer and got one. He came back that next day and had another look. He fixed it that day! Both Kimo and Micah were professional, warm and friendly and didn't treat me like an old lady who didn't know what she was talking about! They also took about 5 minutes and fixed an outside plumbing issue I had with hose attachment to the house. Kimo called me to tell he fixed the heater hook up to the controller and sent pics as my hubby was home and not me. It's humming like a charm now. No more explosions. And hubby gets a hot shower. Not many quality plumbers work repair jobs anymore, but these guys are the real deal and went above and beyond. 5 stars. read more

UPDATE (based on how things ultimately played out): I'm updating my original 5-star review based on how this situation ultimately played out. After the April 2025 service (which was specifically for a drainage issue), the unit began leaking significantly more. A second technician from the company later noted that the indoor unit appeared to be sloped away from the drain. By that point, the system was leaking heavily. The indoor unit was installed with very limited clearance to the ceiling (approximately 1"), which can contribute to condensation and drainage issues. Over the following months, the problem worsened to the point where the unit stopped cooling properly and ultimately had to be replaced. There was also visible mold and buildup inside the unit consistent with ongoing moisture and drainage problems. I made multiple attempts to resolve this directly with the company. Their position was that the issue developed over time and was related to maintenance, and they declined to provide any additional compensation beyond credits for the service calls, which did not resolve the drainage issue. As a homeowner, I relied on the company's expertise and only became aware of potential underlying issues after the drainage problem was not resolved. I understand that older systems can have issues, but the condition of the unit worsened after the service that was intended to fix the drainage problem. Based on how this was handled, I do not feel the company stood behind the outcome of the service. I'm sharing this so others have the full context before deciding who to work with. Additional clarification: To clarify, I did not request that the company pay for a full replacement system - only a partial contribution toward the replacement after the condition worsened following the April service. read more

I would highly recommend Kauai Air Conditioning & Plumbing. I requested a service call to swap out one of my toilets by sending an email over the weekend. I received a phone call to schedule the installation first thing Monday morning. Deepak and Mike showed up promptly as scheduled and handled the job quickly, leaving the bathroom spotless. read more

As usual, Menehune did a terrific job! Minor kine repairs and technician Kimo was polite, informative and did an excellent job. In spite of being busy, my appointment was set up at a convenient time and m very satisfied with the quality of work. read more

Kauai Air Conditioning & Plumbing - AC unit - Heating & Air Conditioning/HVAC Near Me - Kapaa, Hawaii

Recently hired Kauai air conditioning and plumbing to replace a broken toilet. The plumber arrived late, was very slow, was missing for over 20 minutes during the install, bragged about his wealth and how he didn't need this job, and then dragged the broken toilet across my wood laminate floor leaving 3 scratch marks that are permanent. When he saw me watching him drag the toilet, he picked it up and carried it the rest of the way. I contacted the company regarding the damage and was "brushed off" by the manager who refused to address the damage to the floor caused by this employee. This is the worst experience I have ever had with a licensed plumber! Rude, very slow, very expensive, careless and reckless actions resulting in significant damage to my home that will cost many thousands to repair because the plumber carelessly dragged the porcelain toilet against the grain of the floor resulting in damage that cannot be repaired. Service, quality and value are rated F. Please use caution with this company. read more

Beware! My AC was not working so I.called Kauai Aircondtioning and refrigeration to come take a look. They sent a technician within a few days to look at it. He spent about 45 minutes, took the panel off and looked inside, went outside to check the unit and told me that both my inside and outside electronic boards were fried and need new ones. Tech visit $218.72. I paid it. Later I got a bid to replace said boards - cost $ 2715.31. I called cool it Kauai for second opinion. Tech came out promptly. Took a look. Said reset switch was off reset it. Unit working perfectly. Technician cost $175. It only took him 20 minutes max. You decide who would use? read more

I called Kauai Air Conditioning yesterday and they scheduled an appointment for the next Monday. They called me today to say they had a cancellation and got us in early. The technician, Lindsey, was excellent. He was efficient, thorough, and courteous. We will definitely use these guys again. Highly recommend! read more

AJ and Jensen did a great job on our split system AC installation in our home. They were professional, knowledgeable and polite. I've been with Kauai AC for years and they had been very helpful with our older AC unit but when it finally gave out we used them to get a new system which we are so happy with. Great company. read more

Just had Kauai AC & Refrigeration out to for annual preventative maintenance on our one-year old Mitsubishi unit - - and, same as with the original install, their service technician Stetson did a great job!! He not only explained the importance and benefits of the preventative actions he performed, but he was as personable and customer-service oriented as ever! Colby Ayonon nd his entire KACR team are the BEST, highly recommended! read more

Great staff and best quality! Strongly recommend Kauai Air Conditioning, as they listen in regarding what's needed and exceed expectations

I selected Kauai AC to install new AC systems in two of my Princeville condos. Colby, Dayne, Jarod, (and Joanna and Jenny in the office) and team did a GREAT job. Very communicative, professional, fun, and collaborative. I HIGHLY recommend Kauai AC. read more

We had the pleasure of Tyler fixing our AC.... he had to come back several times over the course of our stay and every time he was cordial, courteous, and unbelievably laid back for a guy that had to work while watching us vacation. We are eternally grateful for his expertise and stellar attitude and hope that anyone on the island with HVAC issues has the pleasure of working with Tyler. read more

Their team have totally made my day...week....month!! Now my place is cool and comfortable and quiet. CJ the installer was really good. He clearly explained things, worked quickly and carefully, cleaned up after the installation. Colby, Joanna & Maja did a great job communicating. What a great team they are! read more

We just had AC installed by these folks and we couldn't be happier!! We received quotes from 4 other companies and none of the other companies came anywhere close to being as professional as Colby was. When Colby came out to assess our needs he came up with the best solution and brought a brochure about the equipment he would use. He answered all of our questions and then informed us of things we didn't even think to ask. He took his time during the consult and made sure we all had the right info needed for the best system for our needs. He also sent us a calculator to help us calculate our estimated electric bill increase. After we accepted his quote, installation happened as soon as the parts arrived on Island (approx 1 1/2 weeks later). Installation went smooth and his crew was very professional. I highly recommend this company to anyone who wants their job done right. read more

Colby and everyone at Kauai air conditioning were very friendly and professional. I really can't recommend them enough!

Kauai AC installed our office system at a very reasonable price, thousands below the next bidder and with a suggested time frame for install weeks less . With the rolling blackouts of last July, problems arose and Kauai AC was at our office within hours to assess the damage and immediately initiated repairs. Since then they have serviced the system when needed with the utmost speed and courtesy, always communicating and fully cognizant that a modern office cannot operate without a functioning AC system. read more

Kauai AC and Refrigeration might possibly be the best vendor we have ever had the pleasure of doing business with. From the moment Colby came to do an estimate we were so impressed with his level of knowledge and professionalism. We had worked with several other AC companies over the last 8 years on our residential split systems. We were mostly disappointed and always felt taken advantage of. This was not the case with Kauai AC. Of 4 bids we received their pricing was by far the best and they recommended a Mitsubishi system. It was installed in one day and they accommodated our schedule. Ruben, Thomas and Calvin did an amazing job. Joanne who handled the calendar and billing was easy to work with as well. On Kauai we often have a shortage of quality service providers so it is refreshing to find one of this level. We will now use them for all of our AC needs and strongly recommend them to anyone looking for new systems or repairs on existing. Thank you Kauai AC... Glenn & Kim read more

Had to wait a bit to get an appointment due to their busy schedule, but on the appointed day, they arrived on time, got right down to work and fixed everything in short order. My control panel was found to be the problem so they went to their truck, got another, installed it then checked the rest of the system. So nice to have everything fixed in one service call. Office personnel and service techs we pleasant and professional. Definitely recommend and will use again if needed. read more
