    If you use this company, you better hope you never need them to service or stand behind their work. We keep having leaks from where they installed our solar hot water. They came out over a year ago to fix it and with this most recent round of rains, it began leaking again. After leaving numerous messages, I finally got in touch to report the leak. I was told they were slammed and would put me on the schedule and somebody would call me. That was over three weeks ago. I keep trying to find out status of a repair, but nobody ever calls me back. Terrible customer service, A simple courtesy of a phone call would be appreciated.

    Finally I got my split air in my bedroom, lots of red tape with the city DPP . I already did my leaving room. Jordan did an excellent job, also the installation person that did my wiring, didn't get his name. All my neighbors went with Alternate Energy with split Air units, some with 3-units. Also, want to thank Vince ...Design set up and Leeland my salesperson. If you need a split air or solar, please call Alternate Energy. Aloha, Derek

    I rarely write a review and only take the time if the service is exceptional. If you're thinking of going down the rabbit hole of getting PV Systems (Solar panels, mounting systems, conduits, rails systems, battery backup, installation, inverters, permitting, HECO, HOA, etc.). I jumped all in and headfirst. Here's some background about me. I recently retired from the military, serving over 30 years, this past December 2022. Finding myself with quite a bit of free time to say the least. I conducted a deep comparison and completed way too much research, creating spreadsheets, pie graphs, PowerPoints, Venn diagrams. I sent requests to 10 different solar installation companies and completed 8 different solar estimates. Why did I choose Alternate Energy? Customer Service!!! Here's just a small list of how Alternate Energy stands out ahead of the rest. 1. Locally owned and operated with more than 30 years of experience. 2. Quality of products offered with warranties: (PV panels-REC Alpha Series w/25 years, Inverter Type - Enphase IQ8H, Tesla Powerwall 2, monitoring system (Enphase and Tesla Apps). 3. Customer service reviews from friends, colleagues, Yelp, BBB, and Google were good. 4. Estimate process working with Lionel Ahina (808) 222-4747; lionel@alternateenergyhawaii.com With this large investment in Solar PV System Lionel and Alternate Energy created the proper system for my family's electricity usage. Lionel listened and asked detailed questions on how we live our lives, and how we consumed HECO electricity. Lionel offered detailed explanation of the entire PV Solar system process. He provided me with knowledge, training, project timelines, true expectations working with all the different parties involved (Alternate Energy, HECO, City & County Permitting, and my HOA). He was also willing to share his personal experience in sales for over 40 years. This process into PV can be inundating. Finding the right sales person to not give you the run around, up-sale you a system, quality products, quality installers, warranties, etc... Alternate Energy should be your first call. Yes, I recommend you get other estimates. You will find some sales people are full of sh*t. After you sit down with Lionel and the Alternate Energy Company you will understand. 5. Cost! Everyone's home system cost will be different on estimates. Alternate Energy's price wasn't the highest or lowest compared to others but they offered the perfect cost for my home. After getting 8 estimates ranging from over $43 to just under $33K with additional fees. My "Purchase Agreement" was in the middle. My System Size: 6.00 kW; Panels: 15; Storage: 1 Tesla Powerwall 2. 6. Installation crew. With PV Systems going up all over neighborhoods, you're able to see installation yourself and compare. I was able to ask questions to installers, electricians, homeowners, prior to me making my selection. The installation crew of Alternate Energy is AWESOME!!! Special thanks to the following Chris, Nate, Steve, Sonny, Shannon, Franco. The crew is on time, excellent workers, they have great teamwork, great communication, sense of accomplishment while keeping things light and fun. Chris, Nate, and Steve took the time to explain the entire pre-installation process, provide perspective, communicate required layout changes due to my older home. I appreciated that. Chris takes the time to review the user App on your phone and how the new gateway, generation panel, IQ Envoy works. He explained steps on shutting off the power and what to look for in your PV system production and usage. They are an extremely hardworking group, under extremely hot conditions. They also installed a NEMA plug and Emporia EV Charger 2, 48 amp, which I changed the location a few days prior to installation day. I cannot give enough credit to the installation crew, quality workmanship, start to finish. 7. I agreed to Alternate Energy 17th May 2023, and my Solar PV System was installed on 12th September 2023. The timelines will vary, this timeline was not predicted and to me this is extremely quick. Extremely Satisfied Customer

    As new first time homeowners we've spent quite a bit of time talking to family, friends and researched PV Contractors for our PV needs. Alternate Energy (AEI) stood out above the rest. Thirty years in business and owners comment on Yelp reviews which to me shows good ownership. We immediately felt comfortable with our Project Developer, Miles Yoshimoto. Miles is very friendly and professional and my husband and I liked that he was not "salesy" or "pushy". He patiently helped us figure out what type of system was right for our household usage. We really appreciated Miles responding quickly to our calls and emails. AEl also has a partnership with Hawaii State Federal Credit Union and the finance process was quick and easy! On installation day, my husband, who works in the construction field, said it was a "Quality Install". He appreciated that the installers and electrical crew took the time to explain every step and did a great job cleaning up after. I had to get their names and give them a shoutout so mahalo to Richard, Jade, Alden, Ronald, Reggie & Trey! We have enjoyed using the Tesla app to view our electric usage and how the panels are saving us money! And we have already referred AEI to our co-workers, family and friends. We made the right choice.

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.

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.
