Woo's Electrical & Appliance
Company Overview
We specialize in electrical improvements and troubleshooting in residential settings, in addition to major appliance repair. We apologize, but our services do not extend to small appliances, televisions, or brands including SubZero, LG, Samsung, Wolf, Viking, Thermador, and Bosch.
This family-run business has been serving East O'ahu since 1980. You could say appliance and electrical repair is part of my heritage, as my father, Daniel W., founded the company. After his retirement, I took the reins and now manage the business alone. It’s a privilege to live and work in the same community, especially one that cherishes connection. Having grown up in East O'ahu, I view it as a blessing to manage a small business in this community.

Recommended Customer Reviews

We recently moved into a house. Previous wiring and work done by former owners can be confusing and often incorrect. Some of the 3-way light switches were wired and installed incorrectly. Marvin and Sung diagnosed and corrected the switches. Marvin also coordinated with my pool contractor to properly identify and prep an outdoor GFI outlet for a pool light installation.
Professional, knowledgeable, friendly, honest, great work, and reasonable prices. What more can you ask for? 6 stars!

Knowledgeable, great service and best prices in this area. Took care of a concern of mine so I could sleep a little easier at night. Saved their contact info and will call again when needed!

Thank you WOO'S, the lighting you installed under our cabinets made our kitchen look 10x amazing!!!
Excellent service and clean work!

Absolutely the Best. I'm a Realtor so not only does he do my personal appliances, Marvin and Mike does most of my Clients appliances as well. Never never been disappointed. In fact I've been surprised at their high level of service. A+++++++++++++++

Not sure how anyone could possibly give them less than 5 stars. Their response time and service is immaculate! Marvin and Sung are top of the line professionals who know how to do their job, and do it well. Their work ethic is top notch, topped only by their quality workmanship and efficient timing. The fact that they pay attention to every single detail means everything to someone as nit-picky as I am.
I can see why they're booked out for so long: everyone wants to use them! Worth every second of wait time to get them scheduled. I can finally finish up my never ending project (well, maybe - it just never ends, so we'll see).
Woo's electrical is worth every penny. We would hire them again and at every opportunity we could!
Thanks, June, Marvin, and Sung!

Marvin Woo is the most professional help of all the trades we have had in our 2 houses in Oahu. He delivers the best service and does not try to push you to do something. Even if you want or suggest it. He always gives you alternatives and prices of each. Marvin and wife June. Keep their word. We are grateful to know them

On time, efficient & fair price. Fixed my washer & explained what the problem was what needed to be done.

Used them for repair to several non- functioning sockets and light and ceiling fan install. EXCELLENT service from the highly responsive office to the service team who were professional and friendly . Definitely would use them again.

Have an older home so always wary about electrical issues. I had a couple outlets that were burning up the plugs to small appliances . Woo's informed me they were booked for the next 2 weeks but made an appointment and suddenly received call the next day that they finished a job early in the area and would they like me to have them stop by ? I did and they checked everything out, fixed a breaker and charged me a minimal fee which was very reasonable. They were nice and reassuring and not ""talking down"" to this senior citizen. I appreciated it and I appreciate them! They will be my go-to business for any electrical issues. Thanks for the great service.

Called a day earlier and Marvin came over the first thing the next morning. He was fast and very affordable and got the work done. It was an electrical issue where we had a chain of outlets with one that was burnt out and caused all to fail. Thanks Marvin for great and quick service !
