Knoles Electric

Expert Services for Home and Business

We specialize in professional electrical troubleshooting, diagnosis, and repairs across Honolulu, O’ahu, and throughout the islands of Hawaii.
When you have an electrical issue, you need more than a quick patch or a handyman’s guess. You need Comprehensive Fault Diagnosis. At Knoles Electric, we don’t just treat the symptom (like a flipped breaker); we hunt down the root cause.
Whether you are a homeowner in a classic Plantation-style house or managing a commercial facility in downtown Honolulu, our mission is the same: to identify hidden hazards and restore your system to full safety, efficiency, and strict code compliance. We use advanced testing methods to ensure that once we fix a problem, it stays fixed.

Common Issues We Solve

If you are experiencing any of the following irregularities, our team can diagnose the source and provide a clear solution:

Faulty Circuits & Dead Outlets:

If power suddenly cuts out in just one room (like the kitchen or bathroom) or a specific outlet stops working, it often indicates a “broken link” in the circuit or a tripped GFCI. We trace the circuit to identify where the connection failed.

Frequent Breaker Tripping:

A breaker that trips constantly is a safety warning, not a nuisance. It usually means your system is overloaded by modern appliances or there is a dangerous “short” in the line. We analyze your load capacity to determine if you need a repair or a panel upgrade.

Unexpected Failures & Surges:

From lights that flicker when the AC turns on to sudden power loss in specific zones, these “ghost” issues can damage sensitive electronics. We perform voltage testing to stabilize your power flow.

Wiring Problems (Old & New):

Hawaii’s unique environment poses challenges. We assess older homes for degrading knob-and-tube wiring, and check newer properties for salt-air corrosion or rodent damage that may be compromising your wires inside the walls.

What Our Customers Say

Based on 40 reviews
We had a great experience with this electrician. It has been difficult getting electricians to come out - several have given quotes and then never showed up, but this company was different. He responded promptly, showed up when expected, listened to what we needed done, and completed the job as requested. Reliable, professional, and easy to work with. Would definitely recommend.
Knoles Electric did a great job installing six exterior light fixtures at our apartment building. During the project, we ran into some challenges removing the old rusted fixtures, but Cam helped us find the best and most affordable solution — it truly felt like they had our best interest in mind.
Elijah completed the installation with great care and quality. He also maintained clear communication throughout the two day project.
Overall, a smooth experience and we’re happy with the results. Mahalo Knoles Electric Team!

Found Knoles electric on Yelp, scheduled them to change 6 of my dated outlets & covers along with one light switch. We initially booked the job for a Saturday morning and had an unfortunate hiccup with keys which was my fault; my renovation contractors had the only set with all required keys and they had to reschedule me last minute, but they were incredibly understanding and kind given the situation!

Elijah was the electrician who came out for the rescheduled appointment and he was truly amazing! Arrived exactly on time & was prepared with all of the necessary tools & parts! He was thorough, efficient and fun to chat with throughout the job! He also made sure to vacuum up afterwards despite renovation mess, but this just proves the attention to detail he provided! Can't recommend him, or this company enough!! Mahalo, Elijah!!

Elijah got us hooked up with the hwn electric and we have electric again after two days without power. We have Sunrun for solar, and they provided no help. I’m going to see how the bill is with echo, and then figure out what to do with solar. Neither Hawaiian electric nor Sunrun were any help. Eliza was wonderful.

Elijah replaced our entire circuit breaker box and potentially saved an electrical fire in our home. Things were bad, and I am so thankful he was skilled and knowledgeable. I’m someone who asks a lot of questions and likes things thoroughly explained to me and he was very patient, communicative, and professional. It was very refreshing! 10/10

Elijah was fantastic and a true professional! We just purchased a condo for my mom and needed the electric box updated and a 240V outlet added to power her new AC. Elijah went over all the different options for running the AC’s power line and did a fantastic job navigating quite a bit of distance between the AC and the electric box. We are so grateful for his attention to detail and the care and consideration he took in doing this important work to make sure the electric box is safe for my mom’s new home. Thank you Elijah!

Tonight, on New Year’s Eve, our power went out while cooking a special dinner for our families. Called Hawaiian Electric to report the outage and their recoding said power outages in Kailua and we live in Kailua. The funny thing is that all our neighbors had their power on. We thought that we would be without power until Friday morning (Hawaiian Electric Business hours). I frantically started looking on Yelp to see if, by chance, I could find an Electrician/Company who would be able to do an emergency call. After calling numerous numbers and only getting voicemails I was ready to give up and tried one last number. To my surprise, Cameron personally answered my call and said his crew wouldn’t be able to respond this evening because they were all at New Year’s
Parties. Cameron was very concerned for me and my family and our situation. He asked me to explain what happened. He told me not to panic and thought that he knew the problem and that he might be able to help me over the phone. He told me what to do step by step while he stood by on the phone. Miraculously I was able to get the power back on and complete our New Year’s family dinner. We owe a ton of gratitude to Cameron for being there for us in a time of crisis… a “God Send”! He definitely deserves more than Five Stars! Will recommend Cameron and Knowles Electric.

Knoles Electric is a wonderful company. I was able to get in touch on a Holiday by phone.
I sent him a pic of my damaged
electric box and he solved the problem without coming out.
I have found an electrician for the future. I highly recommend him.

Living in an old house. We didn’t realize how bad our electrical system was. We had melted wiring, rats that ate through a lot of the junction boxes and protective coverings... we’re thankful that our house didn’t burn down.
Knoles Electric, Cameron, came in and rewired our entire house. He had to climb in the attic as well as crawl under our house to get the job done. Since our recent renovation was over 35years ago, he suggested updating our lighting. He installed a bunch of Halo 4” canless LED recessed lights in our living room, kitchen and bathroom. These lights provide great lighting while remaining almost hidden. We got rid of our ceiling fans and had him install simple 15” lights.
Overall…Cameron did a great job. I would definitely recommend him.
If you live in an older house, I would recommend someone to inspect your electrical system. It’s better to be safe than sorry…
Let me know. I know a guy..

I highly recommend Cameron as an electrician for both residential and commercial spaces. Cameron is extremely knowledgeable and proficient in his work. He has beef my electrician since 2021 for residential and commercial spaces.

He assesses electrical issues with precision and always provides the best recommendations prioritizing safety. His transparency in explaining what needs to be done instills confidence, and he ensures all necessary equipment is promptly acquired and used for immediate fixes.

Cameron initially helped fix electrical setups in my home that were not up to safety standards, demonstrating his commitment to ensuring a secure environment. His expertise and reliability have earned my trust, making him my go-to electrician for any residential needs.

Cameron at Knoles Electric is as professional as it gets! Cameron installed a new exhaust vent for us in a very out of date condo. He was able to walk me through everything he was going to do before getting it done which gave a great peace of mind.

With the professionalism and fair pricing, I will most certainly be using Knoles Electric forever!

Knoles Electric is efficient, fast, and professional! I had an emergency situation with a ceiling fan that needed to be replaced at a non casual time, and they showed up the same day to provide fast and reliable service. Cameron also walked me through the issue I had and how he was exactly going to fix it, something a lot of electricians don't do these days. An honest electric company that I will be using for the rest of my life!

Cameron is a talented electrician and also very pleasant to work with. He's done several renovation projects for us, including lighting, outlets, panel work and security... and he's never failed to impress us. His installations are clean, he communicates his intentions and he has great suggestions. As an electrical engineer, I'm glad that Cameron is serious about complying with electric code and doesn't cut corners. We'll certainly be going with Knoles Electric for any future work.

Our home is almost 80 years old and needed a lot of updating. We initially hired a different electrician but we had problem after problem. I was referred to Knoles Electric by a friend, so I contacted them and Cameron came out the very next day. He knew I was already frustrated and we were behind schedule, so he moved things around and put me on the schedule right away. Cameron re-wired the entire downstairs, installed some fans including this huge one, added around 25 lights to our home, and replaced all the outlets. He cares about the work he does, and we'll definitely use him again. Thank you!

Frequently Asked Questions About Panels

1. How much does an electrical troubleshooting diagnosis cost?

We believe in transparency. We charge a standard dispatch fee to come to your home and diagnose the issue. Once we find the problem, we provide a quote for the repair before we begin any work, so you never have to worry about “sticker shock.”

2. Why do my lights flicker when the AC turns on?

This is a common issue in Oahu homes. It often means your electrical panel is struggling to handle the heavy “in-rush” current your air conditioner draws when it starts. While minor dimming can be normal, significant flickering could indicate a loose wire or an overloaded circuit.

3. Can you troubleshoot older Plantation-style homes?

Yes. We provide tailored solutions for Hawaii, which includes extensive experience with older homes in neighborhoods like Manoa or Kaimuki. We can assess the condition of vintage wiring and recommend safe repairs.

4. My outlet feels hot to the touch. Is this dangerous?

Yes. A switch or outlet should never be hot. This usually indicates a loose connection where electricity is arcing, creating heat. Stop using that outlet immediately and call us.

5. Why does my breaker keep tripping?

A circuit breaker trips to protect you from an overload or short circuit. If it happens frequently, do not ignore it. It indicates a faulty appliance, a wiring fault, or an overloaded circuit that requires professional diagnosis.

6. Do you offer 24/7 emergency troubleshooting?

Yes. Knoles Electric provides 24/7 emergency services for critical failures, outages, and safety hazards across Oahu.

7. Can I troubleshoot electrical problems myself?

We strongly advise against it. Residential voltage is lethal, and DIY repairs often violate Hawaii electrical codes. It is safer and more reliable to hire a licensed professional to ensure code compliance.

8. How does Hawaii’s salt air affect my electrical wiring?

Salt air is corrosive and can damage contacts and breaker panels over time. We check for corrosion during our diagnosis and use materials suited for the island environment.

9. Do you service commercial businesses?

Yes. As stated in our mission, we provide “Expert Services for Home and Business.” We can troubleshoot complex commercial electrical systems as well as residential ones.

10. How long does a diagnosis take?

Most standard troubleshooting calls take between 1 to 2 hours to locate the specific issue. Once identified, we can often fix it on the spot.
