David is just the best! He came the day we called, assessed the problem, ordered the part and even came to install it on holiday because shipping had caused a delay. I highly recommend him and will definitely use Sifu Systems again if we have an appliance break down! read more

David was honest and knowledgeable with his diagnosis and offered several options for fixing my dryer. He's super down to earth too. His diagnostic price is the same as most places. I would recommend him if you're looking for a competent mechanic to fix your appliance. read more

I've called him a few times regarding a variety of things, from maintenance on my old AC units, to dryer. Very responsive on the phone, was upfront with his fees. Very knowledgeable and honest if he is unsure about something. I appreciate his professionalism. Reliable & dependable. Will definitely call him again! read more

Called David to repair a broken dishwasher cable that did not significantly affect the ability to use the dishwasher. He arrived in the timeframe he stated, and even texted to let me know he was 30-40 minutes away. He's a knowledgeable and very pleasant person to deal with. He discovered that the problem was bigger than just a broken cable, and showed us that in addition to the broken cable the spring assembly was also broken, requiring the installation of a new dishwasher base. He advised us to buy a new dishwasher when this one no longer works, as the repair would be expensive. He charged me a most reasonable price for the service call. When I have a broken appliance in future he will be the first person I call. read more

I had an issue with my electric cooktop where the switch and/or burner wasn't turning on. Even though David doesn't typically offer phone consultations, he went out of his way to help me troubleshoot as a kind gesture. I want to emphasize that he's a busy guy, so don't expect the same-- I just got lucky catching him at the right time! Fortunately, I know how to use a drill and some tools with my construction background and was able to handle the work myself. David was incredibly patient and kind throughout the process, and thanks to his guidance, I saved a lot of money on service calls, labor, and parts. After troubleshooting, I ordered two new switches directly from the manufacturer for under $50 (including shipping) and replaced them myself. If the burner had been the issue, I would have needed David's professional help, but thankfully, it was a simple fix. Based on my experience, I can confidently say David is honest, knowledgeable, and highly responsive. His willingness to help truly made a difference, and I appreciate him for saving me money. Thank you! read more

Highly recommend this business. Quick response time. Charged only $100 service call - S/B $120. Giving 4 stars for customer service. Would definitely call this company again read more

He has done refrigerator repairs for us several times over the years. We had a difficult issue with the evaporator drain, he came by repeatedly until the problem was fixed. read more

My wife and I moved from out-of-state back to Oahu in September, and we inherited a Bosch compact ventless dryer that worked well for two months but stopped spinning all of a sudden. The last couple of weeks it made pretty loud squeaking noises when it was running. After taking it apart, David showed us a broken belt (which would have been easily replaced) but also what looked like years' worth of dust buildup that he explained was common among compact ventless dryers. He also explained that when this dust accumulation mixes with the Bosch lubricant over the years of usage, it turns to a tar-like consistency, and the machine never works the same again. He told us that we could take the machine apart, vacuum as much of the dust as possible and replace the broken belt, but odds are we would end up spending close to 1/2 the cost of a new machine on repairs, and he could not guarantee that these repairs would be long-lasting. He recommended we get a new machine. We appreciated his honesty. We want to get a full-sized ventless dryer since we have the space for it. Too bad worldwide supply chain issues make ventless dryers so difficult to find in stock! read more

We manage a unit in the Ae'o and refridgerator was not cooling down in temperature. Called and they came out that evening. Even though they were busy, David squeezed us in. After checking it out he was very honest and told us that a quick defrost could be the problem. Will try and if we still have problems, will call him again! Very honest and helpful!! read more

Never ever call this business. He committed to a work date and cancelled last minute. I rescheduled w/ him and he cancelled AGAIN. Very unprofessional and no courtesy to give us notice that he would be a no show. His brother called to explain the situation. TOO MUCH DRAMA. Please do not ever call this company. Not deserving of even any stars but this app requires a star where it is NOT earned. read more

I scheduled through the Yelp platform for service the next day to do a minor repair on my washer. The technician called the day I contacted him and said he had time between other jobs and asked if I'd like him to come by and take care of it. I jumped at the opportunity. He was efficient, fixed the problem, and was on his way. I inquired directly with two other business on Yelp that require phone calls or emails to schedule. Neither responded. Sifu Systems will have my business because of the combination of responsiveness, efficiency, and quality of work. read more

I appreciate David Loo's professionalism and honesty. He diagnosed the problem with the washer, and explained it to me. For my best interest at heart, he preferred not to work on it, because the labor involved, and the high cost to repair it. I trust his decision and I will discuss it with the owner and go from there. Mahalo David! God bless, and all the best to you and your business. read more

Quick response and got an appointment a day later. I made a special request to have a early visit the morning of the appt cause I got called into work and it was granted. Fast work. read more

Davis is reliable fair and responsive. Excellent and stand up guy. I would not hesitate to recommend again. Fixed my dishwasher and didn't charge extra labor when discovered needed separate part. He's excellent! read more

I wish I could give David ten stars. He went above and beyond to fix my stove top when the "cooktop on" light would not turn off. I remember calling different companies on a Saturday and he was the only one who answered the phone. He made three trips to my place over the course of almost a month, replaced the switch and even when I thought something was wrong with the burner, he came over to look at it after buying the replacement part and told me that the burner that I already have is still in working condition. David explained how burners will pulsate at different temperatures. On top of that, he is a genuinely nice, friendly, professional guy who is responsive. I appreciate that he wore a face mask each time he came to my place especially since I was pregnant and just had a baby. Thank you David!! I'm keeping you in my phone in case I need other appliance repairs in the future! read more

Getting my appliance fixed through Sifu Systems and owner David restored my family's faith in appliance repair companies, as we had several of poor experiences with other Hawaii appliance repair companies! When my washer broke with a leak, I called about a half dozen appliance repair companies. David of Sifu Systems was professional, prompt, and honest from the start. He was able to book a same week diagnosis appointment. Our washer part arrived in about 2.5 weeks, and the leaky washer was fixed within 3 weeks from first contact. Other companies simply ghosted my family, or quoted parts that would take months and months to arrive, so Sifu Systems was a refreshing experience. Thank you Sifu Systems for fixing our broken washer promptly! I highly recommend Sifu Systems and plan to use their services again when the time comes. read more

We just purchased a condo a few months ago, and the property manager informed us the fridge was leaking water onto the floor. Our property manager recommended that we replace the fridge because of its age. But before I consider replacement, I wanted to see the leak first hand before deciding if a new fridge is needed... that's a pretty penny. Since I manage several properties in San Francisco, I am use to seeing all kinds of issues with appliances and the leak was actually inside the fridge, leaking down the back wall and the water pulling on the inside bottom until it overflows onto the floor. I contacted several appliance repair companies and David of Sifu Systems was the earliest appointment. He diagnosed the problem immediately and cleared the clogged tubing on the spot. It's been working fine for 2 weeks now. It's hard to find someone quick and reliable in any trade, especially out of state... I'll be keeping David's number. This 5 star rating is well deserved. He kept to his quote for the on site diagnostics and his repair was also as quoted. read more

Very knowledgeable about our Whirlpool washer dryer when I thought there was an issue. There wasn't. He brought peace of mind.

David is honest and knowledgeable. Great communication, came when he said he would, and quickly diagnosed what was wrong with our dishwasher. read more

I got to meet David the washing machine whisperer. All he had to do was listen to the machine and immediately fixed it. Quick response and a fair price. This is the kind of repairman we all wish would come. read more

Our washer decided to give up after 11+ years. I called and David answered right away we were able to schedule an appointment. He was very professional and thoroughly checked everything before giving his diagnosis. I did recommend him to a friend having an issue with her refrigerator. read more

Updated review! This was the second time I'd called David for an appliance repair. David let me know he was booked out a few weeks and would try to squeeze me in. In a family of 5 being down a dryer sucks. I was so grateful David squeezed me in a few days after I called him. He showed up in the time frame he said he would fixed my dryer! Amazing ! Thank you David. read more

I don't normally leave a review before service has been completed but David has been great to work with since I reached out 5 or 6 weeks ago and I want others to know. Our washer was leaking, all signs pointed to the tub seal, which apparently is a tough repair - lot of other companies responded with "sorry we can't help". David provided a reasonable quote but after checking out our unit he explained in detail that while he could replace the tub seal it wouldn't solve the problem and in a few months time we'd be leaking again. He gave us multiple options, we decided to replace the tub. He ordered the part which takes quite some time to ship as it's too large for anything but freight. Here we are 5 weeks later and the part hasn't arrived, and now it seems that maybe it hasn't shipped yet! But this isn't David's fault and he's been super responsive and is trying to resolve the issue. I hope to update this review with a happy ending and more kudos, but if we end up having to cancel the project I'll definitely call David for future needs. Integrity is a big deal to me and David either has it or he's got me fooled! read more

David just left my house. I was so impressed with this young man, so knowledgeable and so honest. He took a look and a listen to my groaning, rattling, thumping dryer, felt around inside the drum and showed me all the dents that were causing the noise when they passed over the rollers. Sigh, apparently someone (not saying who, lol) put something in the dryer that wasn't supposed to be in there. David was honest with me and told that to replace the drum would cost almost as much as getting a new unit, so that's what we're going to do. He also gave me a discount for his visit and diagnostics. I kept his card because he will be the go to person for any appliance repairs we need in the future. Thank you David! read more

Called several people and he was the best at communicating and figured out what was wrong (others came and misdiagnosed). Would call again! read more

If you have ten Yelp tabs open for different appliance repair businesses and feel like you're going crazy trying to decide, stop here: you've found the one you want. Our three-year-old GE washing machine wouldn't start randomly one day. After doing a Yelp search for appliance repair companies I called David from Sifu Systems and he kindly informed me that he was booked out by over a week, and would understand if we couldn't wait. It was a thoughtful gesture that I appreciated and represented his style. We set a date and time; he messaged when he was on his way; and arrived promptly. The diagnosis was failure of an electronics part that would need to be replaced. David indicated an initial estimate he thought it might be, and then looked into the specifics and found that it's a bit more expensive - really bordering on the cost of a brand new machine. The advice he'd give a family member, he told us, was to skip the repair and just get a new machine, given that cost. He also discounted the cost of his diagnostic visit, as he felt it had been pretty straightforward. (With apologies to other Yelpers, while I know it's something of interest I don't list prices out of respect for the business.) Kindness, honesty, and competency - we're saving Sifu Systems' contact information for further appliance issues. Sorry in advance if you call and are told that there's a wait over a week long, because I might happily be contributing to that queue! read more

My electric GE oven, a little over 3 years old and just out of warranty, started to shut down a couple of minutes after I hit the "start" button and an error code appeared in the display. Happened every time and the oven was unusable. I looked up the code online and learned that the error was with the ventilation fan sensor. After looking at the local Yelp reviews I selected Sifu Systems based on their ratings. David came out and ran diagnostics to confirm the part he needed to order and gave me a quote based on the part cost. No charge for the initial visit pending the return visit needed to install the part when it came in. Part came in, he returned and voila: oven fixed. David's a straight-up, competent, and trustworthy kind of guy and I'll definitely be calling him back in the event I have any other appliance repair needs. Highly recommended! read more

I had an issue with my washer and called David. He told me it was a simple reset, walked me through it over the phone, and helped me free of charge. And, it worked! What a great guy! I didn't get to really use his services this time, but I definitely want to give him my business the next time I have a plumbing issue. read more

Our fridge's water line broke leaking water in our newly replaced flooring. We called around to various appliance repair companies who all had limited availability and would cost a min $150 just to show up and diagnose the problem. I already knew what the problem was and the part wasn't too expensive but other places' quotes were pretty high. Called David at Sifu Systems and right away told me the cost would be a fraction of the others and that he could come over at 7:00pm that night which would have been great if we did not have somewhere to be then. Scheduled an appointment for a few days later which was still sooner than the others. David showed up in the appointment window and took his time to inspect the fridge. He fixed the problem quickly and then diagnosed some other issues we had been experiencing. Unfortunately, the fridge has other issues that will be causing major problems soon - some that he could fix, some that were almost impossible to fix but he took the time to explain our options. In the end, he advised to get a new one which we were planning on doing anyway. We had already picked out a new fridge but David shared some of his advice on brands and types to avoid (of course we picked the suspect brand and type). David saved us $$ that day and $$$$$ down the line. read more

David is very knowledgeable. I have a Viking oven that he looked at. He tried to see what was wrong. I knew I needed a Viking specialist but wanted the 'chance um'. He looked at my freezer outside because of the ice build up. He told me what I can do. Thanks a lot David. I will definitely call him if I have any other appliance problems. read more

David has become my go to appliance repair person. I first met David after Labor Day 2021 when I was looking for someone to come repair a dishwasher in our house. Since then I have called him to diagnose a leaking washing machine in a family rental property and replace a part on the washing machine in our home. In every interaction I have had with him he has been super knowledgeable and honest. He also does not talk down to you and is happy to explain what he is doing so you understand. I have never had to call him back so I can't speak to his guarantee. He is hard working one-man show who books up quick but is worth the wait. read more

David is fast super efficient had a great experience all the way around will be using him for all my appliance repair needs! read more

Reached out to Dave. He answered his phone quickly. Explained the issue, which was an ice maker. Texted him the model number of refrigerator.

Installed ice maker and we were good to go. read more

Our fridge broke down and they came out immediately that day. I didn't want to support any big name company and chose to contact Sifu systems since I saw that it was a small locally and family operated business.
