    Clean Installation
    Michael N.

    Extremely Extemely Delayed Review of Bryan Date @ CS Mechanical. A few years ago, our family wanted to escape the Hot Humid Hawaiian Summers and decided to finally install a Split AC System. I had done research and had a few companies come out to give us an estimate. We installed a total of 4 Mitsubish Splits Upstairs and 1 Mitsubishi Split downstairs. I had done research, spoke with friends and ultimately decided on the Mitsubishi System which are amazingly quiet, efficient and reliable. Bryan was the estimator for us and he is extremely patient, customer service oriented, knowledgeable, and accommodating with installation requests. I didn't want to have any of the piping on the exterior of the house for a cleaner installation and he said he was able to run the cooling lines in the attic space and drop them down to each unit. It is this kind of attention to detail that I look for when working with a contractor. Fast-forward to the day of installation, Bryan was onsite to oversee the installation and made sure that our requests were fulfilled. It was a team of 6 installers that were all friendly, professional, and respectful to clean up as they worked. The pictures speak for themselves and when I am ready to have Split AC installed on another home I'll be reaching out to Bryan @ CS Mechanical. Mahalo Bryan and CS Mechanical Team.

    I usually don't write about companies other than restaurants, but decided to write this review because of the great service. After talking to a few people I knew that did AC, I decided to search on yelp and found cs mechanical. I made an inquiry through yelp and Reid got back to me within hours. I did my homework and did get other quotes and asked a lot of questions. Reid was very patient and answered all of my questions. After my husband and I decided to go with cs mechanical, I let Reid know we were ready and asked if we could still get the prices he quoted us a little over a month. Luckily, he said yes and we were able to get our AC units installed in a couple of weeks after that. On the day of the installation of our living room unit and master bedroom unit, Reid came and introduced himself and introduced his workers which I thought was very professional. The workers were very polite and got the job done quick. Now we don't have do suffer the summer heat! I would recommend and have been recommending everyone to use C S mechanical because of their great service, price and work. Thank you Reid!

    Mitsubishi indoor unit.

    Overview: Compared to other local AC companies, CS Mechanical offered the lowest install prices. They have a knowledgeable crew that works quickly and carefully to install the units both indoor and outdoor. The owner/manager Reid clearly puts customer service as his highest priority and was very communicative to ensure we were completely satisfied with the product and final results. Why we hired: We needed to replace two outdated split AC units and add three additional units in a two-story 4 bedroom house. We received quotes from 2 other companies at the same time and CS Mechanical gave us the lowest quote for the Mitsubishi product with the lowest labor costs. Payment: Total cost for 5 indoor units (varying in power/size) plus 3 outdoor units (two were dual systems) and labor was about 15K. This included removal and disposal of old systems, the new systems, the outdoor tubes, remotes and manual, and full install and testing. Card or check accepted. Service: Quality customer service that went above and beyond expectations. We provide feedback on how the outdoor tubes were routed and they worked overtime to ensure it was just the way we wanted. Great communication, respectful of property and space. Quick and effective service. Products: We have had the Mitsubishi units installed for about 3 weeks now and they are amazingly powerful and extremely quiet!!! Compared to our old units these are energy efficient and offer lots of different settings for fan power, angles of vents, and temperature. The outdoor units are also very quiet. There is a small fee to add screens to protect against damage from small creatures (lizards) going inside. Other: Keep in mind that these units each have a tube that runs along exterior of home from indoor install location to the outside unit. There is also a second tube required for draining the inside units. You will need to either paint the tubes to match your home or provide paint to the company to have them paint the tubes to blend in with the house. This will likely be an added fee. The company provide us exactly what we wanted and we would definitely hire them again if needed. We recommend them to others.

    Before cleaning

    About 4 years ago we had our split ac installed by CS Mechanical and had a wonderful experience with Reid and crew. Fast forward to 2022, it was due for a cleaning. My husband and I saw commercials for ac cleaning and read reviews so it kind of scared us on just how much out ac cleaning would cost. I reached out to Reid and asked if they did cleaning and if not, if he could refer me to someone. Thankfully THEY DO SPLIT AC CLEANING! I sent him a picture of my ac and the model info. He responded with a rough estimate and had me set up and appointment with Byran. Following weekend Bryan came and did an awesome job with the cleaning. It was approx a 2 hr cleaning and he gave me great pointers regarding cooking and running the ac at the same time. He said to just be cautious because the cleaning cost can increase or the oil from when I am cooking can build up so bad that the ac can't be cleaned and the coils will need to be replace or the unit itself can break. We are VERY happy with our experience with CS Mechanical. I would personally recommend them.

The old unit was struggling to keep the room cool, even on a cooler day -- and heading into the hot days of summer, it was urgent to get a replacement as soon as possible. Chayden from Kung Fu Air Service confirmed for me that the old system was leaking coolant and that it would not make sense to continue to service it. Once I decided to install a new system, I really appreciated that they were able to perform the installation within just a few days. Chayden wanted to make sure I would get the new unit installed as fast as possible, and arranged to come super early on the morning of the installation, to accommodate an appointment I had later that afternoon. Chayden and his associate were very courteous and professional, and I really appreciated their energy and hustle, and can-do attitude. They worked quickly and efficiently, but also with attention to detail. They made sure everything was done to our satisfaction. The installation looks great, and the new AC is working like a dream. My house is cool again! Thank you very much!

    I had an excellent experience with APV Construction Corporation when upgrading my central AC…read moresystem. My old unit from 1999 had been out of commission for years, and when I started shopping around for a replacement, it felt like most companies either weren't interested in doing a central AC reinstall or were quick to push me toward a split system. While splits are cheaper, I didn't want new condensers blocking my walkway, and I preferred reusing my existing ductwork and electrical setup. APV was the standout. They gave me a straightforward and reasonable quote for restoring the central AC--only slightly more than the split-system options I was being offered, especially considering how expensive other companies have become. They also partner with Hawaii Energy, which helped me get an additional discount. That made the decision easy. From the moment Jordan provided the quote, the entire process moved fast. Lyrissa handled the scheduling and had the installation booked within a couple of weeks. In total, everything was completed in right around two weeks from quote to installation, which was impressive. Mark, Trenton, and Juel arrived right before Thanksgiving to do the install. They were prompt, professional, and efficient. My home is wonderfully cool again, and we enjoyed a very comfortable Thanksgiving because of them. I'm genuinely pleased with the entire experience and highly recommend APV to anyone looking to restore or upgrade their AC system.

    Just in time for this summer heat…read more Last year my split system AC started to leak on the inside of our house, and finally after 27 years she no longer worked I researched best brands, models and companies before reaching out to APB construction. Out of all the yelp and google reviews this one stood out to me. I inquired to get a quote and received a call same day to go over pricing. The call was the perfect balance of inquiry, salesman ship but most importantly true aloha spirit. I got other quotes all similar in pricing but didn't have the same experience I did with my initial quote call. Because of the customer experience I chose this company. I reached out to inquire about scheduling an install and the hard part was done for me, this company truly made the whole process seem less. They removed my old system and quickly installed my new one all in the same day. We had gone without the AC for a few months and it was so nice to finally be cooling off the house. I will definitely be recommending this company to both family and friends when they inquire on what company helped my house get back to its igloo status in this summer heat.

Samsung AC units are such a pain, and barely any techs even want to touch them.

What I love about them is how quick and efficient they are. No messing around, no guessing, they show up ready with everything they need and they get straight to the point. In this hot humid weather it's nearly impossible to find anyone who can respond this quickly, but Air aesthetic never disappoints and always delivers. Their work is solid and surprisingly super reasonable for the quality and care they provide. You can tell they actually care and they're not hear to rip you off like some other contractors.

They assessed the units to ensure that everything was working properly. Charged $792.67 to my card. They were completed with everything in just over an hour. I highly recommend Spencer with AirEsthetic! Very professional and was upfront about everything he was doing and how much it would cost. Thanks again Spencer!
