Really appreciated the help from David. I needed to have the gasket on my washer replaced. He ordered the part and installed it quickly. He's very courteous and professional and I would use him again for future appliance repairs. read more

David is the best Repairman I found over the past 5 years. He warranties his work and honors his agreements. He is also very fair in terms of pricing. read more

Our GE refrigerator wasn't cooling properly, although the freezer was working. I had contacted several other places all of which were busy until the following week. Even though David was fully booked the day I called, he understood what a predicament I was in and kindly offered to squeeze me in after his other appointments. He also provided me a fair estimate range so I knew what to expect in advance. David was friendly, professional, and clearly knows his stuff. He anticipated what the issue was and came prepared with a new fan part in hand. He clearly explained what had caused the failure and how the cooling system worked. He even patiently answered my 8 year old son's many questions and talked story with him . What a great guy! The actual repair cost was spot on David's estimate. I'm accustomed to repairs being tedious ordeals so I was happy to have this turn out so pleasantly. I'd highly recommend Sifu Systems and look forward to relying upon David the next time I need help with repairs. read more

Outstanding service from David and his able assistant, Haruto, friendly, courteous and highly professional...responded promptly to our initial call, scheduled an appointment for the earliest opening and had the necessary part replacement on hand so our washing machine is back in business which is a huge relief!!! read more

options. Business was understanding and honest. First visit was an insurance follow up. Provided truthful and technical sound recommendations. Second visit was to fix a dryer. Both visits were fairly priced and resulted in 100% satisfaction. read more

David is the best! He is so friendly and knowledgeable and most of all, honest! Although he could repair my fridge, he recommended getting a new one. I would definitely call him if any other appliances break down! read more

David gave me a reasonable quote to change the dispenser switch on our fridge so I asked him when would be available . He happened to be in our neighborhood and already had the part so was able to come on short notice and took only about 15 minutes to complete the repair! read more

Thanks Dave. He said he was confident he could fix my dishwasher and he did. I would recommend him. He's polite and fast and good at what he does. read more

The owner David is wonderful! Very knowledgeable and did not look to "up-sell" me. He was about as professional, responsive and respectful as you could ask for. His follow up with me (hired him from out of state for my mother in law) was thorough and much appreciated. High recommend using this company! read more

My GE washer was in need of repair and the Home Depot Protection Plan sent David from Sifu Systems to diagnose the problem. David was awesome, so professional and friendly. The problem was erosion of the tub. Since it was a problem that the Plan would not cover, David suggested alternative measures to try to clear the clogged problem. He went the extra mile so if it works we could save a lot of money which was very thoughtful of him. Since we have to let the solution sit for a day or so, we don't know if it will solve the problem. If not we will have David fix the problem. I recommend Sifu Systems for any appliance problems. read more

If you are not satisfied with his work and try to find a solution, he will pretend to give you an offer but later blacklist your number. What a smart action. I am really suspicious about all those five stars reviews. read more

The service technician/owner David responded quickly with pricing and available times. He was prompt with texting and arrived as scheduled. He called to let me know that he was en route. He repaired our ice maker quickly at a reasonable price and guaranteed his work! He texted to thank me for the business. I will be calling him in the future. Thank you David! read more

"Great" would be an understatement. David is quick to respond and thoughtfully explains what is going on with the Ice MakerMonster that dwells in my Whirlpool refrigerator. The machine was up and running with the replacement of a timer/controller instead of an entire ice making machine replacement (which would have made for two ice maker monsters and a definitely higher invoice). Really excellent, professional, timely, reasonable and thoughtful service. Can't recommend him more highly. Rico Tudor read more

I heard about David and decided to call him on a Samsung fridge that was given to me. It was just outside of the two year warranty. The friend that had given it to me said one repair man gave it a try, but before discarding the beautiful stainless steel fridge which looks really nice, I decided to call David. He came out on a Sunday morning which was great. He assessed the fridge recognized the defect and advised me that the first repair man did the right thing but this model unfortunately is notorious for the defect and he would not, and could not charge for something he knew could not ultimately be fixed. He was honest, informative and did not charge for the visit. I appreciate the candor about the product. I gave him a little for his time and gas; I would highly recommend him. He could have charged me and made something up. But he obviously stands behind his work and knew I'd have to call him repeatedly to continue repairs. And that would not give him a good reputation in the business. As it stands, he was straight up and honest. I hope I don't need his services, but if I should in the future I would call him first for sure. Thanks David! Aloha! Shannon read more

My gas stovetop needed to be converted from Natural Gas mode to LPG mode. I called David. He listened. He told me he's busy and if I want faster service then I have to go get the conversion kit myself at Reliable Parts. I did. He came out. He converted my stovetop. Stovetop is now working great. The whole experience was very easy. I appreciate David's upfront and straight forward demeanor. He's not here to waste your time or milk your cash. I'll definitely use David again. read more

David and Sifu Systems are AMAZING! My refrigerator was making a loud noise and I was very worried. I spoke to David and scheduled a convenient and timely appointment. David was able to quickly diagnose the problem and fix it. (It was the motor). Now my refrigerator works perfect. I am very happy. David is friendly, knowledgeable, and professional. It was a pleasure working with him. I will be sure to call him again for any appliance issues. I 100% recommend David and Sifu Systems. read more

So happy, all around with the experience I had with Sifu! I called David at after purchasing a used washer and dryer on Facebook, which both ended up not working when I got them home. David was quick to schedule me within the same week and was clear about what he does as well as his prices (which were absolutely reasonable!). It felt nice getting a quote, knowing what the price range would be- none of the other company's were willing to give me a quote right away like he did. When he came out to the house, he was able to diagnose and fix both the machines on the spot, leaving my boyfriend and I in such relief. He gave us choices when it came to the repair and thoroughly explained the options that we had. The transparency and wonderful customer service is just refreshing to have when working with appliance repairs. Both machines were working great by the time he left, and our laundry headaches are over. I feel grateful to know that we now have an appliance repair company that we would confidently recommend to family and friends- and can breathe a little easier, knowing if something comes up again, we would call him right away. read more

Our ice maker wasn't working and I found Sifu Systems on yelp. I contacted David (great guy!) and he picked up my call while on another job. We scheduled an appointment and while at our condo he diagnosed the problem, fixed our ice maker and provided us with information on maintaining our unit. I would highly recommend Sifu Systems! Mahalo David! read more

Called David and he came over the next day. Diagnosed the gas range problem and ordered the part. The part arrived and he installed the same day. Now we're cooking again! Highly recommended. read more

David L of Sifu systems has recently done 2 repairs for us. He has been great to work with, knowledgeable and reasonably priced.

Our large 48" built-in GE fridge was leaking from multiple places causing much hassle and anxiety. I was very impressed with David's knowledge and communication skills -- explaining step-by-step his process of diagnosing possible causes of each problem. Most of all, he has a very calming and reassuring demeanor. Totally deserves all his great reviews. read more

Operator owned and the personal pride is obvious. Responded quickly to my request for service, providing an accurate estimate. Showed up on the job with the parts and tools needed to make the repair. Will use Sifu Systems for all of my appliance repairs. read more

David is great! He's saved us money, by being able to fix our GE refrigerator, instead of having to buy a new one! He also worked on our LG washer, ended up not fixing because it was only a chime that wasn't loud anymore and HomeDepot warranty wouldn't cover that. He also fixed our GE oven, which the self cleaning lock was stuck, and we couldn't open it. He was able to get a replacement for the automatic lock, and install without issue. Our GE oven was over 13 years old at the time, but is still working fine till today. It's nice option, self cleaning our oven 2-3 times a year, depending on how dirty it gets. David is honest, and responds quickly. we definitely call him first, if we have any appliance issues. Save money and call him first, there is a charge to diagnose, but it could save you $$$$ in the end. read more

David did an awesome job! He fixed our gas dryer which he thought would be an easy fix only to find that something else was wrong. He left twice to find parts for it & stayed way over his time. He stayed till the job was done & he fixed it! Can't thank him enough! Great job David & thank you for keeping your prices reasonable! read more

We have several homes and used many appliance repair companies over the years on Oahu. By far Sifu is the best, we have used them 3 times in the last few months. Very honest, calls back, follows up, and prices are good....very professional....our choice for now on!!! read more

Excellent quickly professional service. Dryer belt was broken. Did not realize how often we need the existing dryer. Within a short period of time and a very good service dryer was fixed quickly. Will continue to use him in the future for other appliances. read more

David was terrific!!! I called to see if they service LG washing machines and he said he can be there the next day. He kept his word, arrived on time and cleaned/serviced my washing machine (which hadn't been done in forever). Price was reasonable too! I have 2 toddlers and wash clothes constantly. He discovered the reason why water kept pooling in the gasket and cleaned it all out and fixed the problem!!! I wholeheartedly recommend this business and will be calling them again for appliance help! read more

Dave was great. Honest and arrived promptly. Although he was unable to fix our old appliance he was honest and recommended avenues to replace the unit. read more

SIX STARS!!  My Whirlpool refrigerator was leaking water from the water filter and I went right down the list of appliance repair companies listed on the internet and Yelp.  I called or email Apex Appliance, Ohana Appliance, Ali'I Appliance, and Akamai.  Apex advertises that they respond in 5 hours, and it's only been 3 months right now.  Akamai  called me back and said he's in the middle of a job and he'll call me back.  Gook luck to that one.  Ali'I Appliance responded and sent the tech to my home.  They said the tech would be there between 8-12.  He never bothered to call saying he would be late and arrived at 4:30 in the afternoon.  Both my wife and I make over $50 an hour which amounts to $400 each of wasted time for us.  Why even take off from work if he's going to be that late.  When the tech arrived he looked at the problem and said he needs to order the part from the mainland and I told him to air freight it in as the part is very light.  Guess what he never ordered the part.  I contacted the company for an update two weeks later and never got a reply.  REAL PROFESSIONALISM. Going down the list I called Sifu Sytems.  The tech is the owner (David) of the company and he took a look at the problem.  He adjusted something and told us if it still leaks let him know and he'll be back.  There still was a slow leak as we found out the incoming plastic water line was cracked.  David went down to Reliable Parts and got the replacement line and fixed the problem for us.  This whole process took about 3 months starting in January calling and waiting from one company to the next.  My advise for anyone that reads this review is to call Sifu Systems first for any type of appliance repair.  You'll get a timely response and reasonable bill for the work done at your home.  For all of the other companies that seemed to busy to respond,  it's not always going to be this busy and I hope readers will call Sifu Systems first. This is an honest review of a good company. read more

First of all David is a people person...very personable. Makes a huge difference when your tech explains the process and charges. David was extremely responsive to every call and text leading up to repair day. He provided a fair quote...compared to other companies. Gave me a range since there can always be something else wrong once the repair is underway. On the day of the appointment...David texted he was on his way...well within the appointment window. Arrived very professionally dressed...mask on...vaccination card available upon request...ready to work. Luckily our issue was a pretty straight forward broken water dispenser line...which could be repaired without having to dismantle too much. Within about 20 mins David had our Kenmore fridge back up and dispensing water. Due to the time and parts involved...he ended up charging us a little less than originally quoted. As we all know...that almost never happens in today's business climate. I will definately be calling David again for my next appliance repair. Thank you David and Sifu Systems from an extremely satisfied customer!!! read more
