Bay Valley Appliance Service

You can count on Kuan Ng to be on time, professional, and thorough. He is the only one we trust with our 20 year old Sub-​Zero refrigerator. He arrives with parts and tools to meet any eventualities, works quickly, and protects all of the surrounding elements that are easy to damage inadvertently during repairs. He is not a «handyman,» but an experienced professional appliance repairman.

Kuan fixed my misbehaving Wolf range in about 45 minutes. He showed me how to directly order the parts I needed in order to save money. He fixed the ignition system, the char-​broiler, the wheels on the back of the range, adjusted how the oven fed in gas, and fixed the oven light. He came exactly on time – a day after I called. So very quick and detailed service! Thank you!!1!

Our Wolf range was having some issues. I called Kuan on Monday afternoon. He called back within a couple of hours and made an appointment for the next day. He showed up within the 2-​hour window he gave us and did an amazing job, teaching us a lot about our range along the way. He’s friendly, efficient, REALLY knows his stuff and his prices are fair. We had several other service companies try to fix our range over the past couple of years while it was under warranty and they NEVER got it right. Kuan knew right away what the problem was and had the right parts in his truck. Don’t let anyone else touch your Wolf!

If I could give Kuan ten stars I would. Figured out the problem with our Wolf range immediately. Totally knowledgeable, showed up 5 min. early, super friendly. Tip Top, A-​1 all the way!

Kuan really knows Wolf. He fixed the ignition problem on our six burner range top in one very busy hour. Clearly explained everything he was doing. Then cleaned the coils in our fridge without me even asking. Pleasant and professional all the way.

My 20 year old Sub Zero refrigerator and freezer were not cooling properly. I phoned him Saturday morning, he came out Monday afternoon. He diagnosed the problem and had the necessary parts along with him. He replaced the evaporator and the ice cube maker. Very professional, neat, clean. Clearly explained what he was doing. I would use him again and recommend him.

As a general contractor I greatly appreciated Kuan’s professionalism. He was on time diagnosed the problem over the phone before he showed up with the parts on the truck. I called him at 10AM and he arrived at 12:30PM. Additionally he made repairs that I had not talked to him about. My Wolf stove is ten years old and I hope to have last the rest of my lifetime. I believe with Kuan’s repair skills that will be an easy goal to reach. The price was well below other quotes I had early in the morning and he had no attitude about it being ten years old as some repair vendors had. He is one of the the real human beings.

What a treasure the Bay Area has in Kuan Ng. We thought for sure the 30+ year old subzero was about to die but Kuan proved us wrong, thankfully! Kuan even helped us with other aging appliances like the Thermador ovens. The repair was not cheap but I think Kuan’s rates are reasonable. I’m in no position to compare since there is nobody else like him. Again, I’m no expert but it seems to me that he is very knowledgable with subzeroes. It also turns out that the rental management company that manages my housemate’s property uses Kuan’s services for their high end properties.

Kuan was very prompt in returning our phone call when we were having trouble with a burner igniter on our Wolf stove. Even though he came here for that problem, he identified other potential problems with my refrigerator and our hood. He was knowledgable about the appliances, and answered all my questions. I would highly recommend him.

If ever you have a problem with your Sub Zero I will tell you it is a privilege to have Kuan Ng service your appliance! I have never experienced such service in this day and age! Thank You Kuan!

Kuan is wonderful! He has repaired my SubZero refrigerator many times and always comes out quickly and knows what to do. I called him this morning because the freezer was leaking, and he was here this afternoon. He fixed the door closure piece, cleaned out the whole motor area, and then checked out my dryer for dirt in the exhaust pipe. I would never use anyone else!

We have a 2001 Sub Zero refrigerator, that was serviced less than 8 months ago by another top rated company on Unilocal.However, I would warn anyone, and suggest to anyone that has Sub-​Zero, or ANY other appliance — look no more, this is your man!!!
After a subsequent call to the previous mentioned European brand repair specialist, I was told this would be a $ 700. repair– claiming that I needed a new motherboard. I could not believe it, since 8 months ago I spend over $ 800 to repair the same refrigerator. They charged me the $ 69. «service charge» and I said I needed another opinion…
I turned to the sub zero website that lead me to Kuan of Bay Valley Appliance. He came the next morning, bright and early and fixed my refrigerator. Not only did he identify the problem immediately, he was super courteous, fast, and full of information and recommendations about our refrigerator. He fully serviced our Sub Zero, adjusted the shelves, hinges, replaced lightbulbs, and the motherboard did not need any repair. (The problem was a clogged drain tube.)
Kuan, went on to service my Viking stove, and check out the igniter. AND clean out my Kenmore dryer which, I did not complain about, but he noticed that it needed the service. All of this –he did for less than half of the price that I was quoted by the other European repair company!!!
Again, I would highly recommend Bay Valley Appliance and Kuan to anyone in need of Appliance repair. Don’t waste your time with the others, call him now!

Kudos to Bay Valley Appliance and Kuan. He came on the day I called and fixed my 1989 Wolf oven. It came with our new house, but the oven was not working. It would cling and clang for 20 minutes before it even started warming up. We really didn’t relish the thought of buying a new oven and range. But it turns out that servicing old Wolf ovens is a specialist job. Wolf/​Sub Zero wouldn’t service it because it was built before the companies merged. Most of the service people I called wouldn’t even come out to see it. I finally found someone who came and then wasn’t able to fix it. And then someone recommended Bay Valley. Kuan came over, did some detective work under the oven, identified the problem, and fixed it. It’s working fine now. He saved me a lot of money. He was very nice and very tidy, cleaning up everything as he went. He also gave me some tips for maintaining the oven and the vent filter. I will definitely call him again.

We needed the ice maker on our 24 year old Sub Zero replaced. I had called Sub Zero (
) at their 800 number and actually got some helpful trouble shooting tips from their technical support. But when it was obvious that the unit needed to be replaced, they referred me to a local «authorized» service company. The estimate from them was around $ 600.
Over ten years ago, Kuan had serviced our Sub Zero when he worked at another appliance shop. I was glad to have tracked him down. He was able to come on the same day and replace our unit for about half the price. Incidentally, besides just replacing the ice maker, he also checked out our aging refrigerator and determined it was still in good working order. Over the phone, he had suspected that the ice-​maker solenoid valve would need replacing (just because of the age). But when he checked it out, he said it was working fine and did not need to be replaced. (What repair person wouldn’t have taken that opportunity to take advantage of you for additional fees?)
Kuan is very experienced and works efficiently. He is friendly and helpful. And his service is reasonably priced. He also checked out a minor problem with our Wolf stove, on the same service visit. Most important, is that he can be trusted.
I highly recommend him for Sub-​Zero and Wolf appliances. But he probably is very knowledgeable on other appliances as well.

I have a 15+ year old Wolf stove, on which one of the burners had started to flair from the underside when lit. Wolf doesn’t service these older units anymore and referred me to a San Jose service company. I tentatively scheduled a service visit with them, but never heard back. I Unilocaled «Oakland stove repair» and read an earlier review for Bay Valley and gave them a call. Kuan actually walked me through, on the phone, how to remove my stove’s burner assembly, and diagnosed the problem and suggested who to call for parts! He very easily could have suggested a pricey service call, but I sense that he’s as honest as he is knowledgeable!

CALL BAY VALLEY APPLIANCE FOR SUB-​ZERO REPAIRS AND DON’T USE BOX APPLIANCE!
Kuan is amazing. We called him because our fan and ice maker in our Sub-​Zero were having issues and he went way above and beyond to fix the issues, reconfigure our lighting, and fix the door close switch at no extra charge. He’s an extremely professional, nice, and honest person to do business with.
He also warned us about what we need to be proactive with from a maintenance perspective to ensure the longevity of the motor.
Having worked w/​Box Appliance before and their outrageous prices, I know for a fact Kuan did it for half the cost and double the quality.

Great guy and technician! At first, I had the impression that there was only the Box that could service our SUBZERO until I did a little more digging and found out about Bay Valley. I’m glad I did! Kuan was a top notch serviceman! He explained everything thoroughly and even had the time to advise us to clean the radiator on our wine fridge too! There were no extra charges and he did everything well! I’m glad I went w/​Kuan vs. our old technician (J&M Vigil Appliance) who previously told me that it was our motherboard that was at fault for not making ice. When Kuan troubleshoot it, it was just a misplacement of the ice box that didn’t set the signal to make ice. Kuan also replaced our defected coil which was leaking freon from the previous installer who didn’t install it correctly. I highly recommend him and will continue to use him as our technician for our subzero.

I am glad I saw the previous reviews regarding Bay Valley Appliance Service. After his service of our Subzero refrigerator, we would also strongly recommend Kuan Ng for his prompt, professional, efficient and friendly service. He arrived precisely as scheduled. He diagnosed the problem with our unit, confirmed that the condenser was still under warranty and proceeded to help us repair and clean our unit. Along the way, he provided a lot of suggestions on how we could best clean and maintain our unit to maximize its useful life. He also helped us with our stove top problems and questions even thought we did not call him for service on that unit. Now, both my refrigerator and stove top are both working well. His fees are very reasonable, but most important he really seem to know his stuff around our Subzero and stove top.

I highly recommend Kuan Ng of Bay Valley Appliance Service. He is NOT a handyman — he is a Sub-​Zero & Wolf Range repair specialist. Unilocal needs to add another category under Home Services — «Kitchen Appliance Repair & Service».
If you own a Wolf range with an expired warranty, typically you can expect some very hefty repair bills and lots of runaround about availability of parts. Not with Kuan. I called him, described the issue over the phone and he was at my house within 2 hours with parts in hand and the range was fixed within 15 minutes. He was also more than happy to discuss other features and/​or quirks of my Wolf range, Bosch dishwasher and Electrolux fridge — even though he does not officially service those.
You will not find much info on this guy in either a Google or Unilocal search. But I think that is a great sign as it indicates word-​of-​mouth is his primary source of business — not expensive marketing that results in expensive service.
Call him at 510−846−8832.
