Repaired my washer. I had to work with my extended warranty program, but Fuse Hawaii were very helpful and kind throughout. Ivan came to do the inspection and repair. He was calm, friendly and did the repair quickly. Happy customer.

Wow! The reviews are accurate! I did a quick "Appliance Repair" google search with our Zip Code this morning. Aleksandra O. scheduled the same day diagnostic for $115 and Ivan the Technician was so helpful! He showed the problem and will be back in a day or two with the part for the Repair. Thankful for a trustworthy Technician with experience and skills. Thank you all so much! 🙏💞 Add On: The repairs were completed in 2 days. Thank you so much! We appreciate the extra time Ivan took to test and balance the dryer before leaving. Truly effective services! Mahalo! 🙏💞

I called and Ivan the service technician came out the same day. He was incredibly professional, didn't try to up-sell me, told me what was wrong and the different options I could take depending on my budget and plans for my washing machine. He didn't force me into any option thay didn't serve my purpose or plans. He was friendly, courteous amd very knowledgeable. The quality and value was excellent. No hidden charges, no games, just good old-fashioned people helping people, old Hawaii. I would definitely recommend them and use them again in the future. What a breath of fresh air!!
