My family has used D&D for other split AC installs and was highly recommended by them. We've had split AC units replaced and serviced through D&D. Derek, Ilima and Sage have all been great to work with. They have been very responsive to any communication sent. The work done was great and the prices were very reasonable. read more

I used D & D to replace my old ac's and I just had them cleaned. The service is always excellent, professional, and friendly. They explain exactly what they're doing step by step and let me know what's going on at any time if I ask. Ilima and Derek are superb and their entire crew is so nice and friendly. Their work is always exceptional and done well! Always fast and they don't cheat me like other companies tried to before. So I stick with them because they're reliable and good!! Thank you for your hard work because summer is coming and my ac's are clean!! read more

I contacted a couple different AC installation companies for estimates. Derek came out the house on a Sat to talk us through the process and come up with a plan. Other places were telling me all the reasons I couldn't do something, but Derek came up with a plan to accommodate my old, single walled house. Both Ilima and Derek were very patient with all my questions...and I had a lot. On the day of installation, the guys showed up on time and ready to work. They were all so conscientious and respectful. They did a fantastic job with all the nuances of my house! It was definitely not easy, but I felt they really took the time to make sure it was done right, not just fast. Sage, Tony and Matt and Dean and Dustin (the electricians) were great on installation days. Can not say enough good things about this group! read more

Derek and Ilima have provided excellent service to us in the past. However, I have left 4 messages in 3 days and nothing. Now shopping for a different vendor read more

Matt came exactly at 8:00 am. My AC was full of gunk and he cleaned it out very well. Now I won't be breathing whatever was in there! He had to clean three AC's and was quick and thorough with each one. Thank you for your great service! read more

Ilima setup my preventive maintenance appointment and followed up with me the evening before, that was great. Sage came over to my home and performed the preventive maintenance, WOW, he did a GREAT job! very polite and professional. Will be calling them again for my preventive maintenance service. Thanks D&D for everything! Clayton S. read more

I contacted D&D for a quote to replace my old split system with a new Mitsubishi system. Derek showed up on time, was knowledgeable and easy to talk to, and offered us options for a new system. D&D's estimate was very reasonable compared to another we received. I appreciated Derek's responsiveness in answering our follow-up questions to help us decide, and he was accommodating when we requested specific changes for locating the exterior units. On the installation day, he was thorough in the walkthrough with us to confirm the installation details before they started. The installation went great, and we are happy with our new system. The crew did a great job - they were respectful, clean, and efficient. Upon inspecting the finished interior and exterior product, I appreciated the quality of the installation and their attention to detail. It was a great experience working with Derek and Ilima, and I would work with them again without hesitation. read more

I had an entirely favorable experience with D and D Air Conditioning. A neighbor had recommended Derek, as he had outfitted her yoga studio years ago with air conditioning and she was very pleased. When Derek came to my home to check out the three rooms I wanted splits AC in, I immediately picked up on his professionalism, attention to detail, sincerity and friendliness. Having had a career in customer service, I thought I would like to give this fellow my business. The pricing was similar to several other bids, but honestly Derek's good attitude was a notch above. Similarly, Ilima, his office manager, was helpful and very friendly. The crew of six arrived promptly at 0800 and completed the job by mid afternoon. They were all pro's and very courteous. I couldn't be happier with my air conditioning! Thank you Derek and team! read more

Excellent service. All calls were returned within 24 hours. Tony arrived on time to service my 10+ year old Mitsubishi split air unit. He was polite and did an great job! Ilima was very personable and made the payment process very easy. I will definitely use their service again and will recommend them to friends and family. read more

I had my 21 year old air-conditioning system replaced with Mitsubishi split system just about a month ago from D & D Air Conditioning. The price charged by D&D is comparable to other Mitsubishi AC contractors in Honolulu. It is all about "the service" that sets companies apart and I'm so glad I chose D&D. The staffs that installed the AC in my 2-bedroom and living room/kitchen townhouse were respectful, efficient and very neat. I'm just sorry I did not write this review sooner as I can't recall their names. In any event, there were 3 installers who came on time at 8AM and worked through what is generally considered lunch time and completed the installation by 1PM. And they left the area they worked in cleaner than when they came. I would (and have) highly recommend D&D to my family and friends/neighbors. read more

D&D staff and field techs are by far the best to deal with. I called them to request a service call today and was told they were really busy and had no appointments available for another 2 weeks. They offered to put me on a wait list which I was so grateful but to my surprise the rep called a few hours later and sent a tech over today, the same day I called. OMG what good customer service. I would recommend them to anyone needing air conditioning service. Call them!!!!!You won't be sorry. Helpful, courteous and just plain awesome.. locally owned and in business for many years. They installed my split system 16 years ago in 2004. read more

Great service and attention to detail. Systems work great and service reps took their time to ensure everything was working correctly! Fair pricing and quality service! read more

Derek was very responsive, thorough and a great help getting the documents together for the HOA Board to review. This culminated in speedy approval of the installation of a Mitsubishi split-air conditioner for my unit. The price was excellent and compared favorably with other Diamond certified companies. Derek and a team came to my home as scheduled and efficiently completed the installation. For the first time in more years than I can count I was able to sleep comfortably in my Hawaii home during the hot summer. This is a family-owned business that has many years of experience in the islands. Thank you Derek and crew! read more

Derek of D&D Air Conditioning installed a Mitsubishi split air conditioning system in our house a few months ago. He and his team were very professional and efficient. Now that it is hot and humid, we are enjoying it. The system cools the air quickly, and it is fairly quiet. read more

Excellent service from this company. I purchased 5 Mitsubishi air conditioners to replace my 21 year old air conditioners. Derick and his staff did a fantastic job changing out my system. All of the workers were personable, hard working and took care to make sure nothing was damaged in the house as a TV, sofa, etc had to be moved to get to the existing units. They were very thorough in cleaning out the old refrigerant lines and checking the drain pipes to make sure they worked as required. They also made sure they did not leave any rubbish behind as they rechecked every room and outside area to make sure they were clean. At the completion of the job, Derick patiently explained the remote system and each A/C unit as I had 3 different types. He also assured me that I could call them at any time should I have any questions. A pleasent surprise was Derick informing me that I am eligible for a $150 per unit rebate from Hawaii Energy. I highly recommend this company for your A/C needs. read more
