We contacted Sean after Island Comfort installed 2 new Lennox split AC's that leaked. Sean installed 2 AC's that work great, little maintenance and cost less. Since that original installation in 2023, we have used him to replace 3 others, including the 2 Lennox that continued to leak even after being "fixed" multiple times by Island Comfort. Sean is diligent, reliable, communicative, knowledgeable and honest. We highly recommend and will use him for all future needs. read more

Sean was amazing and super fast. I needed a new compressor and 3 splits put in. He was quick to schedule and put it all in, in within 7 hours. He was genuinely sweet and I have no complaints. He even came to Hawaii Kai during the Kona low storm to double check placements of splits. AMAZING! This whole process, less than a week. AHHH AC again! Thanks Sean! read more

Sean fixed AC unit which any of AC company could not fix at 1611 Mokulua Drive. He He told us that he learned this technique through years of programs he had to be solving. He's an experienced trust worthy AC technician. read more

Thank you for deep cleaning my AC unit. Really apprecite fast communication and high quality service. Mahalo!

Contacted a few AC companies for an urgent drain/block issue and Sean from AC star got back to me promptly. He was able to attend to it the following morning. He is very personable, knowledgeable in diagnosing the problem, fixed it, gave suggestions to prevent it from happening in the future and very reasonably priced. Thank you Sean very much. It sure was a pleasure having you attend to my AC problem. read more

Extremely knowledgeable, intelligent, skilled, competent, experienced professional! Highly recommended! read more

I can't be more satisfied with this company! We had a problem with our central air conditioning system and had two companies trying to fix the problem, they ended up charging me and system still had an issue. This guy came and in less than a minute told me what was wrong, came back with a part the next day. Thank you A/C Star!! read more

I hired Aiden to look at a commercial unit at a chain store. He said he went to the store and found that the motor was bad. He said the motor was on backorder. Me and another coworker has tried to contact him numerous times after this, and it goes straight to voicemail. We have left at least 10 messages with no return call or email. I'm with a multimillion dollar corporation that has lots of work in Hawaii. What kind of company turns down work from from someone willing to pay you via credit card as soon as your done? I have plenty of work to offer in Hawaii but seems hard to find contractors wanting the work. I'm dumbfounded by the integrity, and work ethics of some people who own businesses. I don't like to leave bad reviews, but this one was warranted for wasting my time. read more

Had my AC go out on me on Friday 2 July 2021. I have Extended Home Warranty so I submitted a claim. 3 days went by and they were unable to find a technician. I started calling around. I contacted about 6 different AC companies who were either very short on phone or were just too busy to help. Luckily I came across AC Star and spoke to Shawn. He was able to come out the same day. He was here at the exact time he said he would be. He was super knowledgeable, very professional and had the problem fixed within all of 30 minutes if that. I will definitely be going through AC star for all of my future AC servicing and repairs. Highly recommend if you are in need of servicing or looking for an AC install! read more

Sean installed a split unit in our commercial space about 2 years ago. He chose the size and brand. Price was $4,500 and included 5-year warranty on parts. In Nov2018 there was a water leak of unknown origin. We suspected the AC, but we weren't sure. Sean came to check the unit and declared after 15min that the leak was coming from a neighboring commercial space. Property manager made an assessment shortly after and diagnosed the source as our AC unit. Sean didn't answer repeated attempts for contact and another AC technician from a competing service was able to fix the problem. That technician said our unit is too small for our space. The same AC unit didn't get cold last week, so our first call was to Sean. Sean said we owe him "Three hundred something" from the Nov2018 15min leak / no leak incorrect diagnosis. We never received a bill, so we asked for an invoice. He agreed to take a look at the unit on Friday of that same week and never showed up. To date, we still haven't received an invoice and he no longer answers our phone calls. We found another AC technician from another competing service, and he also said our AC unit is too small for our space. We do not recommend AC Star for new unit installs because he didn't honor the warranty. We do not recommend AC Star for diagnosis because he couldn't do what a property manager could in identifying a leak. read more

Sean came to my house last week to fix our AC that was producing hot hair. A couple of hours later the AC was fix and producing ice cold air again. My family and I were so happy since we live in ewa beach, you know how hot it can get here. I also like that Sean was so friendly and charged us reasonable price as well. We will definitely give him a call back if ever that our AC will give us problem again. I definitely recommended AC STAR to my friends and family. read more

Very professional and knowledgeable. Really happy with the work he did! Will definitely be referring to family and friends!

Sean was the name of the repair specialist who fixed my Air-conditioner at my home. It wasnt blowing cold air and was making shrieking sounds, took him just an hour to find the problem and fix it. He was very friendly and explained what he was doing as he worked. would definitely recommend this company!!! read more

I found AC Star when I was searching for a technician to conduct normal preventive maintenance on our AC systems. Nothing was broken, however a wise man once told me you should get your AC components checked out periodically and professionally cleaned. Their guy Shaun (sean?) got back to me within a day and scheduled a day in the next week, quoting me $350 over the phone for both the split and wall ACs for our house. When he got here, he changed the price to $497.38 because the unit needed more work than he thought. I left a check with my family and went to work, only to find out he was out of the house in about two hours. His work quality, attitude, and over-all customer service were five-stars, however the price he charged (versus what he estimated to get in the door) was way higher than the quotes I'd received from other technicians, and I wouldn't have asked him to come out had he said he may need to raise it once he got into the unit. Bait and switch tactics reduced my rating to 3 stars. read more

After seeking a number of quotes from various A/C companies, Sean at AC Star was the first to get back to me, and the only one to honor an on-site appointment to assess the property. I was able to have him inspect the space in which I wanted to instal a split A/C just a few days after the initial call. When Sean arrived, he was very polite, made a quick assessment, and provided a recommendation on the spot. Having previously researched BTU's vs space requirements, I found his recommendation to be reasonable. The most important selling point was his ability to install the unit within 2-3 business days from accepting the quote. The only other company to return my request for quote stated they were backed up to August. Installation of the Fujitsu split A/C went smoothly and without any surprises. Sean showed up when he said he would, and completed the job in a timely manner. The installation was clean and both the compressor (outside) and the inside air outlet are practically invisible. So far, I haven't had any problems with the unit. I have already referred AC Star to a friend, and I would definitely recommend this company to anyone needing a quick and effective A/C solution. read more

Ok first I apologize for the lenghty review, but I feel like i have to write my first review ever, and do it justice. I am from Florida and had no idea who to call if i had any problems with anything within my apartment in Honolulu, and to be quite frank, I am used to being ripped off by all handyman types on the mainland, so, I expected the same on Hawaii when my AC stopped working (stopped working after one month upon moving in). Anyways, I called a few AC repair companies and had them come over. My dad taught me to always get a second opinion. My budget was already razor thin, and when I heard the first couple of quotes, I almost had a panic attack. I knew nobody, so I had it repaired by the cheapest out of the bunch. Long story short: i paid $700 dollars for repairs, and it worked for 3 days. For 10 days I kept calling them to ask them what the heck happened, but they weren't answering my calls. I finally just gave up and started calling AC repair places again, only this time I would have to max out my CC. Two companies came around, with the first telling me I should replace the whole system, and that it would cost ten to twelve thousand dollars. I called my parents, I didn't what to do... so I called one more number cause either I was going to buy a fan, or just wait until I save up some money. This guy from AC STAR showed up on time, and told me exactly what my options are. Turns out I didn't have to replace the whole system, but just the outdoor unit. He actually went up into the attic, and checked my indoor unit, which other guys didn't do... He said that just it would just need cleaning, but its condition was good. To finish my story, I saved a whole bunch. Take it from me, you can trust this guy. read more

Good service! They answered the phone on the first time I called and scheduled an appointment for someone to come out. They showed up on time and they solved and fixed our A/C problem. read more

I called guys from ac star to take care of my ac. They were swift and experienced. Service was great. I will use them again.

AC Star called them friday morning i got an appointment the next Day after 12Noon on a SATURDAY !!!! WOW !!! sean is very knowledgeable, very Professional, Really Nice and HONEST!!! He told me My central air was just low on freon he recharged it $366 including tax !!! AWSOME quick service !! read more

Our condo is new, but started to leak from the Air conditioning drip pan in the walk-in closet and it's supposed to be a luxury condo! :( Anyway we called so many AC repair companies on the island, but many of them didn't even reply to us. AC STAR is the one replied to us quickly. Today Sean the repair guy came, he was thorough and professional, and explained what was going on and gave options. Thank you, Sean! Highly recommended! read more

We have a central air conditioner and few days ago there was a burning smell coming out of the vents. It stopped cooling a day later. We called AC Star and they told us it was a fan blower motor most likely. They came on Sunday (wow) confirmed that it was motor, came back the next day fixed it! The Guy Was nice and in the get it done mode. Thank you AC Star!! read more

Solid service. Fast and easy fix to a split AC that had a clog in a hose. These guys pretty much did a routine service that only took 30 minutes. read more

Our split AC unit was dripping and AC Star responded quickly and came on time. Sean was able to fix the problem very quickly. I reall enjoyed meeting Sean and I would give them 10 stars if I could! read more

AC Star to the rescue! One of our central AC units died and they came out within a couple of days and installed a new unit just a couple of days later! They didn't try to oversell us and replaced exactly what part was bad, no more. Sean was great to work with and I highly recommend his company. read more

I called to schedule an appointment with Sean. My HVAC system was blowing hot air and the compressor and fan was slow to start up. He immediately scheduled me for a Sat appointment. He was also going to be in my area the morning of. I personally ended us figuring out what the issue was and solved it myself. I purchased a new compasitor and boom it started working. However, with the service and promptness that I received from Sean I will use him for monthly maintenance for my HVAC system. If service like that is from the get-go I would be a fool not to use him. read more

Sean is a very honest person. He could have done as I asked but he gave me better advice about what to do. I would call upon him again for services. read more

Had Sean remove my old central a/c unit and install a new energy efficient one. Very fast response and cheaper than a lot of other local a/c installers i had called. Sean is very knowledgeable, friendly and honest. Would recommend him to anyone. read more

The best, most comprehensive a/c service on the entire Hawaiian Islands. Great service, very knowledgeable and courteous. I strongly recommend this guys. read more

I made an appointment for him to clean my 2 A/C due to the requirement of my landlord. He showed up and looked at both of the A/C units. He basically said both of the units are either bad or broken and he wouldn't feel right of charging me for it. I was so surprised to know how honesty he was. He could have charged me for something and I wouldn't even know. All in all thank you AC Star, you are the best!!! read more

I had my filter changed by this company in a couple of my establishments. Professional and courteous each time. A big recommendation for all who need AC maintenance. read more

I called and Sean said he could come the next day! Yes, the NEXT DAY!!! We have often had to wait two weeks or more for other AC guys to come (or even call back). We have been having problems for two years with our new AC. Sean checked it out, explained what was wrong, and quickly set about fixing it. My husband enjoyed talking with him as he worked. We highly recommend Sean. He is prompt, efficient, and professional. The AC is back to working like when it was brand new. Excellent experience! read more

The thermostat for my home central air wasn't working. I called one highly rated company on Yelp, and they weren't accepting new customers which seemed strange since I would expect that much repeat business for HVAC repair. Anyway, their loss was my gain because I then called ACSTAR. They answered right away and I got an appointment two days later. Came on time and quickly fixed the problem for a reasonable price. I highly reccommend! read more

I had been having trouble with my split a/c system when lo and behold Sunday night it dies. Not only does it die but it dies leaving this high pitched squealing sound. No way to turn it off. So my mom said call Korean guy they faster, we waited 1 day, well the 2 she called never called me to schedule to come out.So back to sleeping with ear plugs. so I emailed AC STAR since it was in the eventing, figuring they would get it in the am and we could at least schedule something.So Tuesday I figure holiday so not going hear from anyone so its cool, so here it is Wednesday at 8:53 am i called the office no answer just a answering machine so I left a message saying I emailed and was not calling & would like someone to call me back. Then again at 10:38 am same thing, 11:20 am & finally 5:50 pm. So I don't know if its me or they just don't need the business but I would've appreciated a call telling me something even if they couldn't help me, point me to someone who could. Poor customer service... I don't want to give any stars but to post this I have to at least give 1. read more

Sean is great! I have had him repair and replace multiple units for many houses that I property manage. He is always fast and responsive and their prices beat anyone else on the island. I will wait 5 days just to get a call back from another company, where AC STAR will have the job done in the same amount of time. Highly recommend! read more

Called AC Star yesterday and after 30 min Sean called me back. He was the first to respond. Sean said he could come by today at 8AM. 7:50AM he is at my house in Ewa Beach with his helper. Both were very polite and respectful. The company van is very clean and looks professional. Sean's diagnosis rate was the lowest of any of the other AC companies you will find on YELP and the fee is applied to your total bill, not that way with some of the other guys who charge you just for coming out to take a look and then start the meter after that. I tried diagnosing the problem my self and after several hours of asking Google and Youtube I finally gave up and call professionals. I am so glad I did. After checking on a few things and confirming with his gadgets he told me I needed a free-on charge, new gas filter, and air filter. He didn't have the right gas filter or sized of my air filter in his van. He said he had another appointment to go to and would get the parts and come back in 2 hours. 1hr 50 min later he came back with the parts and got to work. Sean showed my where in my Attic I could find and how to replace my high end air filter. My wall thermostat hadn't been used in almost a year so the battery leaked causing the motherboard not to work properly. He tried his best to clean the board but not luck. He felt bad for me with all these expenses piling up so he offered to get me a new thermostat at his price. He said he will come back on Friday at 12 noon to finish the job after he gets the right thermostat. So far so good! I will definitely call Sean again to maintenance my central AC unit. read more

I started calling ac unit repair people because my ac broke down on Saturday and now it's Monday, and the first one I called would take 2 weeks to come out, the next a week away. One I called, and while the phone was ringing, I get a text from them stating please either text back or email them. I did. They texted me back at 10pm at night saying they are too busy. Then going down the list I called AC Star. Sean picks up right away. I was very surprised and great full. He asked what the problem was and I told him. Now I am expecting him to say I will be there in a couple days or so. But he said he would be out within a couple hours. OMG. He was super professional and very kind. My ac kicked the bucket and he apologized to me for that. So now I need a new one. So now I ask thinking it will probably be a week before he could get back here. HE CAME BACK THE NEXT DAY TO DO THE INSTALL. Yes I all caps that. He was that amazing. I would certainly use him again and tell anyone who needs his service to use him. read more
