John responded to our request promptly on Yelp and offered a same-day appointment during a busy peak season. He was extremely professional and quickly identified that our AC was running but not cooling due to a bad capacitor. He was well-prepared with the right parts and fixed it on the spot. Highly recommend Silicon Valley Comfort for anyone in the South Bay needing fast and honest HVAC service! read more

Even though it took several days for John to fix my HVAC, it is now working perfectly! You just have to be very patient while working with John as he has so much clients. read more

I had a great experience with John at Silicon Valley Comfort. I was having issues with my water heater and initially thought I might need to replace the entire unit. Instead of pushing for an expensive replacement, John recommended diagnosing the actual problem first in order to save me money. Not only did he end up saving me a significant amount of money, but he also went above and beyond by working after hours to restore hot water to my home as quickly as possible. It's rare to find someone so honest, knowledgeable, and dedicated to customer service. I highly recommend John and Silicon Valley Comfort to anyone needing HVAC or water heater service. read more

Johnny was knowledgeable, fast to respond, honest, funny, and personable. He came out to fix my AC unit in a day. He explained things very well. I will definitely use his services again in the future. read more

Extremely professional and dedicated to the task. Helped with the issue in no time and very reasonable too.

Excellent service! John quickly diagnosed the problem, and had our AC running again in no time. Very professional, knowledgeable, and explained everything clearly. The pricing was fair, and the quality of work was outstanding read more

I had a great experience with Johnathan at Silicon Valley Comfort. I was having issues with my AC, and he was able to come out within three hours. He quickly identified the problem, explained what needed to be fixed, and got the AC working again right away. I really appreciated his fast response, professionalism, and efficient service. Highly recommend! read more

John came by in the evening at 5pm from West San Jose to my unit (30-45 mins drive) to inspect why the AC stopped working and after thorough diagnostics, confirmed I needed to replace the compressor fan motor and add a hard-start kit (as 1 was not installed). He promised he will get new parts (OEM for Carrier/Bryant) and installed the new parts next day working under the summer sun. Nice hardworking young guy, and knows exactly what he is doing. Highly recommend him. read more

Amazing. For the first time in my life I had AC repairman coming in two hours on Saturday night (as opposed to usual two weeks) and fixing the blower motor at once. Not only that - John diagnosed the problem as gradual capacitor degradation and after measuring it and seeing it having only one third of specs capacity, which caused motor overheating, simply replaced the capacitor, eliminating the need to replace the motor and saving a ton of time and money. Great job! I highly recommend him and will definitely call him for any future repairs. read more

Great service. Over the phone he can a diagnostics quote and was clear about his process to evaluate the problem described. Arrived on time with updates when he was on his way. And serviced the thermostat finding the fault and fixing it. Super friendly and courteous of the home. Will call them again next time we needy HVAC service. read more

Our unit had a leak from not only our HVAC system but also from our plumbing. John was nice enough to let us know that we will need to turn off our water until a plumber could come and fix the pipe. He also did a thorough job with checking our HVAC within the attic and outside. Turns out, whoever installed our unit previously did a terrible job. Thanks to John, he was able to fix our unit and it is working perfectly. This was an emergency job so we can not thank him enough for the hard work that he did. read more

Our AC stopped working during the recent heat wave. John came out after hours and was able to fix the problem. If you need a knowledgeable pro you can count on him. I would recommend him for future jobs. read more

Our A/C went out on Monday night during the heatwave. I called 20 people who couldn't schedule me for 2-3 days and then spoke to Nina who could schedule me later that day. She and John were running a little behind because they were so busy and arrived at 8pm and had me back up and running by 9:30pm. They had 4-5 more appointments to go to that night! They did a great job and were very knowledgeable. Our pup was glad the AC was working again. read more

Silicon Valley Comfort - Heating & Air Conditioning/HVAC Near Me - San Jose, California

John is always responsive and provides the best guidance and support. He installed our AC unit back in 2017 and since then has been our main guy for anything AC or HVAC. I highly recommend his services as he provides a honest and detail service. read more

My AC stopped working right before the Great Labor Day Heat Wave of 2022. John and Nina worked me into their busy schedule even though I was up in San Mateo. They identified the problem (a bad capacitor) immediately and installed a new capacitor with a hard start kit, which should give my 10-year-old compressor some extra longevity. I will definitely call them for any future issues. It's rare to see such care and dedication to helping people in distress. read more

Our heater had some debris stopping it from functioning properly and John came right out! Not only did he fix the issue, but he explained what the issue was in a clear, concise manner without overcharging me. Thank you!!!! read more

My AC went out at 4pm and after calling 7 other "24 hour HVAC" companies who told me they wouldn't be able to get to me for a couple days, I called Jonathan and Nina at SVC. They came the same night and stayed until the morning hours to identify the problem and implement a fix. It required them to come back a few ours later due to the blower needing soaking for cleaning. They called me and provided updates as when they would be back. When they came back they completed the job quickly and with very fair pricing. Jonathan and Nina came to my house wearing masks and were respectful of our no shoes in the house rule(we have a baby). I would highly recommend them to anyone looking to get their AC fixed or repaired. They were both very meticulous with their work and it shows that they take pride in the quality of work they produce. I will definitely be calling them again for my HVAC needs. read more

Silicon Valley Comfort is the Best Best Best for dong any HVAC services including mini split system. To be honest, I have called so many different HVAC services and most of them lacked of the technical knowledge for Japanese Mini Split system. John and Nina always take an extra time to explain what could be a better way to install and suggest different options for the customer to save money. First time John and Nina came to look at my mini-split system, and I can tell they are an expert for installing it, no matter it is US version or Japanese. My mini-split system is 2-zone LG Japanese version, John and Nina are very patient and they carefully walked through my ADU (Accessory Dwelling Units like apartment) and give me their opinion/thoughts/option for installing it. John basically will guide you through what/how to do it for entire installation (requires Control Unit, Condensed, Lineset, Power Line, Water line etc.) and will explain the customer an option what the customer can do it them self to save money. With John's guideline, I was able to install 2 control units and run the linesets, powerlines and waterlines my self, and leave the rest for John to help to finish it. This saved me a lot of labor and money for this installation. John was even given me an extra lineset for free as one of my lineset was few feet short, very nice installation and works well. The installation was so great and good, but my mini-split system needs to be going through the city inspection. Unfortunately, my mini-split system was failed, it is not because of the installation or anything, it was that stupid building code that requires to use tamper resistant cap (locking cap) for the valve on the condense unit. And, I have very hard time to find the right size for my system, I tried many many different place, and still couldn't find it. And most people doesn't know what they are. I called John again for help, John and Nina were trying to help finding it, Nina tried to get me at least 2 times for the tamper resistant cap, but no success. John and Nina did not leave you alone, John and Nina was spending an extra time to help even though it is so hard to find. I met Nina at least twice and got different size of the caps, however none of them were fit for my system. Then, John came again with his big HVAC truck. At the beginning, John show me a lot of different size of the tamper resistant cap, but all of them are still too small. I can tell Japanese version of mini-split system is kind a hard to get the right size in US. But John didn't give up for helping, John spent extra almost an hour again to help me find the cap from his HVAC truck, luckily John found the right size for me finally and those were fit perfect for my system. NOTE: John and Nina were helping for Free after the installation, John even gave me those hard to find tamper resistant cap for free. John and Nina 's service are the BEST BEST BEST and I am very impressive for their service. Thank you John and Nina again. At last, I want to say that you could see John's passion for helping people and not only just making money for his business, this kind of service that I couldn't see anywhere else. John and Nina are just like your close friend who is willing to spend extra time, extra effort to help you. Hey, what do you say when you need HVAC service, call no where, just call John, Nina or Silicon Valley Comfort. read more

This is my second time calling Johnny to help with our HVAC needs. He fixed our A/C unit when it failed this summer and most recently he fixed our furnace which started dripping profusely. Johnny is a great guy. He's personable, knowledgeable, thorough, and conscientious. Beneficial traits for a home service technician. read more

Jonathon came out and was professional and most if all HONEST! He found my t-stat was bad and went and found exact t-stat needed and got me back up and running on the busiest day of the year! Words can not Express how impressed I was not only with his work...but how reasonable the bill was when he finished. Silicone Valley is my #1 AC repair company from now on! Thanks Jonathon and your team of professionals! The Guild - San Jose read more

Silicon Valley Comfort are top notch! When my air conditioner needed servicing, they quickly diagnosed the issue and presented me with various options. I was extremely impressed with how knowledgeable they are, as well how friendly they were to speak to and work with. In me, they have found a lifelong customer, and get my most enthusiastic recommendation. read more

Fast, same-day service at a fair price! Our A/C stopped working last night, on the eve of multiple days of 95+ degree heat. I called multiple HVAC companies (including the company that installed our A/C), but no one answered or returned our calls last night or today. When I finally found SV Comfort on Yelp at around 8am today (Sunday), Nina immediately picked up and put me on the schedule for the day. They had a busy day and were running late, but they kept me up-to-date on the delays and were very apologetic. I appreciated that they kept me informed of the timing. John quickly diagnosed the problem and had the right spare part in his truck. While doing his work, he also discussed several ways to improve the HVAC setup in my house but, as another reviewer noted, he wasn't pushy at all. Just someone who was sharing his thoughts and knowledge. Our A/C works now and we are ready for the rest of the heat wave! Five stars for working on a Sunday night, providing same day service, and getting my A/C up and running again! read more

John installed a complete AC and heating system for me. He does excellent work. He is very thorough, pays close attention to detail, is easy to work with and his prices are competitive. The only downside is scheduling, since John is a one man company, sometimes the job previous to yours runs longer than anticipated which affects John's arrival time to your job. This wasn't an issue with me because I am retired and John and I agreed ahead of time that either of us could reschedule at the last minute. If you don't have that kind of luxury then you might want to include some kind of clause in the contract regarding arrival times, if the work requires more than one visit. read more

On a recent hot day we noticed the a/c not working and searched for a local company that could come out and take a look. We found Silicon Valley Comfort and were impressed with the many good reviews. When I called I got John to go through what was happening with our air conditioner. Quite to my amazement he guided me over the phone to look at several components and was able to diagnose the issue with the burned circuit board. Within 24hours he was able to get the specific board we needed and come to our house after hours to complete the repair. He spent about an hour to go through the whole system and make sure it was actually the circuit board and then replaced it. The system kicked right on and work perfectly - very impressive. John really knows his a/c stuff, was very professional, sincere and the price for the repair was reasonable. We will call on John in the future for some planned cooling upgrades. Highly recommended, read more

I seriously don't think I can explain what wonderful people Nina and John are. We have used Silicon Valley Comfort a few times over the last couple years and they are reliable/ honest and always take the time to explain things in detail. I would highly recommend this company to anyone!! read more

We called a lot of HVAC companies before landing on Silicon Valley Comfort. They were able to fit us in their schedule and come out the same day. They quickly assessed the issue and provided great insight into the problem along with what we needed to do to maintain a healthy system. They were super easy to work with and I'll definitely use them to maintain our A/C and heating going forward. Overall great experience especially compared to other HVAC companies we tried to call on the same day. read more

We first called SVC because our air conditioner was just blowing room temperature air, it ended up being completely full of pet hair and almost completely clogged. We were looking to update so it was a good excuse to do so. We ended up replacing the entire furnace and air conditioner. I am so happy we used SVC, not only did they install our new furnace, I asked them about the Nest thermostat. I went out a purchased one, and Nina installed it for me....she taught me how to use it and even showed me how I can control it on my phone. Both John and Nina are professional and extremely helpful and answered all of our questions. I highly recommend this dynamic duo. read more

Amazing company. Other people we called couldn't schedule us till days later, and wanted to charge insane prices for the diagnosis of our ac, and wouldn't tell us the cost of parts and recharge. Nina knew her stuff, scheduled me for same day, and her and John fixed our ac in an hour. They were wonderful people, more thorough then any other hvac company we've had come out years prior, and didn't try to trick us into products we didn't need. They were upfront honest and friendly, and I would recommend them to anyone having ac problems. read more

After 12 years of trying other A/C companies, Silicon Valley Comfort is the company I will depend on from now on, thank you Johnathan and Nina! My HVAC system was knocked out of commission by workers doing a home renovation. Oh no, my wife and I were facing a cold night in the Bay Area, something we did before and do not want to experience ever again. Unfortunately, it was after 5pm on a Friday night and the weekend before the Thanksgiving Holidays. The A/C company that installed our system was not available, so I started to call all other "24 Hour" companies. All I got was answer machines after 10? 20? tries, and those few that answered were not available within 24 hours. Johnathan answered on the second ring, and I was able to schedule my appointment that same night! When Johnathan and Nina arrived, they were kind, courteous, and professional. They both followed all protocols with masks and distancing in this state of Covid we are experiencing. I have a Bryant system and both Johnathan and Nina were familiar with my model and all the controls. Within 10 minutes of their arrival, Johnathan determined the problem was a blown fuse. Nina quickly reset all my original settings on my thermostat, and helped get my heat flowing again. What further impressed me with Johnathan and Nina was their confidence and knowledge about A/C systems and working with them in general. I have had my home since 2009 and have worked with two other professional companies for my HVAC system. Since 2009 I have had my home checked at least twice a year by these other companies. The other two companies did not point out that water leakage, or signs of water leakage, was an issue. After just a few minutes, Johnathan was able to spot that rust, or signs of previous water leakage as an issue. He said it could indicate a variety of problems and he recommended that they be addressed. Wow, after 12 years of twice-a-year maintenance checks and this was never pointed out to me. Johnathan caught this potential issue in a few minutes. Johnathan and Nina are a young couple, and I appreciate the passion and knowledge they have shown. I am changing my maintenance contract over to Johnathan and Nina and will recommend Silicon Valley Comfort to anyone I meet. read more

Of course my air conditioner stopped working during this heatwave on a Sunday. John was one of the very few companies with 24/7 service. As you can imagine, he was swamped with calls. When it became evident that he would be too busy to stop by on Sunday, he sent a portable air conditioner to my home so that I could get some relief. By the way, if you've never used a portable air conditioner, They work quite well, if not a little bit noisy. Last night around 830, Carlos stopped by on his way home from a very long day and was able to diagnose and fix my problem within 30 minutes. John and Nina were very good about keeping in touch regarding the scheduling. Should I have another HVAC problem in the future, I would not hesitate to call them. read more

I had a great experience with SVC! They were able to schedule our appointment within just a few days of my initial call, and Carlos did an excellent job giving our HVAC a full maintenance service. read more

After scheduling with another company for a broken AC (that company couldn't come out for another 2 weeks), my husband found Silicon Valley Comfort online, called around 8pm at night, and somehow they were able to schedule us in for early the next morning. They arrived on time, and upon checking out the AC, John realized the problem was not with the AC, but our 40+ year old electrical box. A few parts needed to be custom made for the hookup to the AC to work again. Any other company would've said it's not their problem, as it was an electrical issue, after all. However, John and Carlos took on this project, called up their electrician buddies, and made trips to get the custom parts made, fixing it all in one day. Within just 20 hours of receiving our call. On top of all this, John made the sting of the cost of it all easier on us by also ensuring that our AC and furnace should be in good working condition into the near future. I just canceled my appointment with the other company (who still wouldn't have been able to come look at the problem for another week). Thank you guys for all your hard thinking-outside-of-the-box work! You're my HVAC guys from now on. read more

Highly Recommend The service was fast, reasonably priced, and my A/C works again. They are available 24/7; I appreciated being able to call on a weekend to schedule a weekday appointment. They were very accommodating, and fit me in very quickly. John explained everything he did very well. He did also recommend some maintenance work to be done later, but he was not pushy at all. I appreciate the balance he struck, and I will definitely call him again if something new goes wrong. read more

Please note, I do not write reviews...and I just had to write one for Silicon Valley Comfort. I called SVC on a Saturday night at around 9:15 PM and he was at my door by 10:30 PM. He stayed until 11:50 PM and had me back up and running by the time he left. And no, I did not mistake my AMs and PMs. SVC provides 24/7 service. He did not rush through any of the work and was extremely thorough - ensuring he checked every possibility so that he made sure the problem was fixed. My husband travels a lot so when something goes wrong, I am at a loss as I have two kids and trying to make service appointments is a nightmare (cause either we have to sit at home for hours waiting for someone to come or they are screaming and I can't even talk to the person). So having SVC provide a service in the evening when my kids were none the wiser was wonderful. Price wise...I thought for sure it was going to be expensive for not only a weekend call but an evening call, but he was so reasonable...I actually wanted to pay him more as I felt he did an amazing job and was charging hardly anything. Definitely would use SVC again and recommend SVC to anyone. read more

My furnace stopped working at around 6pm on December 30, 2021 and after calling 7 other "24 hour HVAC" companies who told me they wouldn't be able to get to me at least until January 4th or for a couple of weeks, a neighbor helped me find Jonathan and Nina at Silicon Valley Comfort (SVC). Jonathan and Nina squeezed me into their busy schedule and came out that same night at 11:30pm. They identified the problem, explained that the fuse on the furnace had blew out and that it needed to be replaced to get the furnace working again, which didn't take very long at all. Nina and Jonathan also installed our new Google Nest and walk me through setting it up. They were knowledgeable, reliable, friendly and had fair pricing given it was New Year's Eve Eve and very cold. I highly recommend this company to anyone looking for a good, knowledgeable team. read more

Called in to get a rough estimate quote over the phone. Johnathan provided it along with a bunch of info and tips. Really impressed that he was willing to share knowledge over the phone and give his opinions on options for AC installation and furnace replacement with all the nuances. He even welcomed a follow up call if I had any further questions for him. Just very impressed with the openness and advice, thanks. read more

Found them through google. I had issues with AC condensation overflow and the owner came by the same day and fixed it --- or I hope he did. Would not know for sure since he never came by like he said he would a few days later to make sure his fix isn't 'leaking'. He kept pushing it out -- it was the third time today that he said he'd come and didn't. When I confronted him he labeled me as narcissistic and as someone who has issues. Really??? I paid over 1800 dollars to get this sort of treatment? Also he seems to have forgotten half the things he said. Not following through and then arguing with the customer about it is no way to conduct a business. I will absolutely not use them again. read more

I was extremely happy that they were able to fix my AC. Despite working late into the night, the owner was meticulously diagnosing the problem and found the root cause of the problem - which was a bug that got stuck in the unit. He has great customer focus and cared more about addressing the problem than charging dollars for the service. I already have plans to have them back for cleaning our unit. read more

John is fantastic, knowledgable and timely. Can't recommend Silicon Valley Comfort more! Took my call late afternoon when my A/C went down and in a pinch for the weekend - he came late that night and didn't leave until it was fixed. Even quickly looked at my duct work and made some very effective adjustments on the fly. Great service. read more

This review is long overdue. John and Nina are the best. They helped me out with my dad's rental property when I couldn't find anyone to give me an honest quote or opinion about the work that needed to be done. Some companies didn't even come out even after scheduling an appointment with them. You will not find a harder working team than John and Nina. They went above and beyond with the installation of the new heater and inspected the heating ducts for us. They are very thorough and do amazing work. Will be recommending them to my friends and family. Thank you! read more
