    After 3 no show, no calls to conduct an annual AC maintenance, I gave up. Save yourself the trouble and skip NS Air.

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.

I appreciate the timeliness in rectifying the issues, thus I am updating my review to 4-stars. Thank you for understanding and fixing our AC!

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!
