I had them diagnose a leak in my air conditioner. They claimed it was a $1000+ part, but it was actually a $10 part. They didn’t even mention the correct area, which was an easy to find valve seal, I had to find it myself. Any shop doesn’t want to find a $10 repair. Two other shops gave me wrong information as well, but one of them finally got it right. My air conditioner is working perfectly now. Maybe they screwed up honestly, but I would say perhaps these guys want your money, despite being very capable, or they just want to lie. I paid them for the false diagnosis.They can fix your car for thousands, then actually the repair is something that cost them less than five dollars. I would say get multiple opinions from different shops And don’t tell them where the leak supposedly is, plus test your system yourself with UV dye kit that you can get for $15 at O’Reilly auto parts. ;).

Excellence in providing expert service with graciousness and friendliness. I am grateful to Cool Tech’s Simon and Stephen. For the great care and superb repair, and finding the problem and providing the solution, mahalo. I recommend this business for detail, thoroughness, and professionalism. 👍🏾👍🏾

I fully could not recommend Simon and CoolTech more.I service my entire TURO rental fleet, personal vehicles, commercial tour vans.These guys are reliable, honest, on time and most definitely KNOW-IT-ALL ABOUT AUTO-AC.Do not go waste time going shop to shop in Kalihi.Forget dealer-stealer.This is the type of mechanic you always wanted your friends to recommend.

So friendly and professional. Price was fair. Love dad and son

The father and son team were truly incredible. They were able to identify my air conditioning problem after other mechanics were not able to find the cause. Their price was reasonable, and they were honest and hospitable. It was completely refreshing to have such a positive, no stress experience in doing a major car repair.

Superb service! Friendly staff, able to get to the cause of the problem immediately, and motivated to save you money on repair and replacement parts. I definitely recommend Cool Tech for any type of car-air problem!

Oh my God! If you have any air-conditioning problems with you car! You got to check this place out. This father and son are the most honest guys youll meet, very caring, very honest and very great pricing. They will check you cars air conditioning system and have it done the proper and professional way. Thanks would highly recommend anyone to go here, even before going to your dealership if your cars warranty is expired. I had a problem wit my air conditioning and they fixed it in 30 minutes. Now Im cruzing in an ice box on those hot and humid days, take it from me! There the best for n town & I dont think other shops can compete with their prices.

After reading all the reviews here, Ive decided to pick them to fix my aircon. Without a doubt, all the reviews here were accurate. Steven and Simon were honest, friendly, and accommodating from the start. In my case, Nissan would want me to change the whole system, instead of just the defective part which they did which saved me money. Thanks again for their fantastic customer service. If anyone needs aircon repairs, come see these guys. The only thing I would correct from the other reviews, they are not father and son. Thanks again Steven and SimonPedro

Simon really helped me out with my AC, very prompt, speedy and friendly service, highly recommend them!!!

This place is one of the best. Very reasonable prices around.

Great job on my ac
