  This is a great company.
Turned on my computer today and was greeted with Trojan Spyware disguised as Microsoft.
Called And was asked to bring in my computer. Within an hour the... read more issue was fixed at a fair price.
I hope I don't need them again but would not hesitate to use them if needed.
I highly recommend this fine company!

  Life never goes perfectly and this leads to the reason that I like J&S. I had a screen replaced on my Lenovo Yoga.

Jason neglected to ask whether or not I... read more was using a stylus on the screen which I do. He wanted to come in with a competitive price so he put on a non-OEM screen and my stylus did not work.

When I brought this to his attention, he immediately voided the invoice without my asking and put in the OEM screen.

I was self employed for my whole career. Whenever I made a mistake for my customers, I immediately corrected the mistake. Not because I was in fear of a bad review, because I worked B2B. There were no dealings with the public.

Rather, I have a conscience and I knew how I wanted to be treated.
Jason acted the same, and that is why I highly recommend using him.

  Phenomenal team!
Jason and Sean are absolute pros, extremely  knowledgeable and very accommodating.
Backstory before we contacted J&SAdvanced IT:
We have a 7500sq ft home with a large yard and have been trying... read more for years to get Wi-Fi stability. We tried a few retail systems, Netgear Orbi, Tp Link Deco, all satellites hardwired and plenty of coverage, they would work great....50% of the time, but HomeKit switches and devices, Ring, Sonos, garage doors would just randomly disconnect, we finally gave up and decided to get professional help.
We didn't want a bunch of different companies visiting our house so we really did our research.
Based on reviews we selected J&SAdvanced and hit a home run.
Jason's initial visit was about 45mins he clearly explained everything they would do to fix our situation, he followed up with a very reasonable estimate that evening, we made our payment for parts and he scheduled us for a week later.
Jason and Sean arrived on time and fully prepared. 2hrs later we were up and running, (they powered through some unexpected service provider record keeping obstacles, our fault)
It's been 2 weeks of solid and stable connectivity, and coverage everywhere.
If you are experiencing any Wi-Fi/Networking issues, save yourself the frustration, these are definitely the right guys to call.
Seriously

  Initially my home had a mess of coax and Ethernet cables in a small box. There was also a mess of Ethernet cables converted to phone lines. It just dove... read more me crazy as I am a very organized person. I also wanted to have all the Ethernet cables connected so I can directly connect my computer or make AP points. I decided to do my research and found these guys.

I cannot say enough how amazing they were. They were very responsive, I was able to text them questions leading up to my appointment, and able to give them an idea of what they were walking into and what I wanted done.

When they came, they did their job efficiently, cleanly, and most importantly, carefully to make sure everything worked. Room by room and panel by panel they required the Ethernet cables as necessary, labeled everything as necessary and were able to clean up the hot mess that was in my I.T. box.  

I would highly recommend them!

  I left a message and received a prompt call back from Sean. He was so nice and helpful over the phone. Like an expert should, he listened to my problem... read more and walked me through a series of questions. After the phone call I was able to fix my issue from a simple phone call and Sean didn't even charge me. Extremely grateful for the call and help. Judging by my interaction with Sean I can tell this is a top tier service company and would highly recommend! Thank You Sean!

  I took my four year old laptop in to see if it would be worth fixing or if I would need to replace it. Jason replaced the hard drive and... read more it runs faster than when it was new! Communication was excellent and service was incredibly fast! I am recommending this business to anyone who will listen!

  Hands down! I had an amazing experience. The owner was able to assist with answering all my questions and I would definable recommend them to anyone for their I.T service... read more needs

  I was looking for prompt and reliable I. T. service and I found it! My laptop was hacked, it got malicious software installed. Windows support tried removing it, but it... read more did not work. It continued working extremely slow and my security software was not detecting anything wrong.
I called and spoke to Jason, explained situation and he had me drop off the laptop to check it. They got back to me promptly with recommendations and estimate.
They clean it up, change to an SSD and clone it, installed protection software and as a bonus fixed number keypad. Just like Jason said with his recommendations, the computer was going to run fast like new, and it does. It feels like a brand new laptop.
Thank you J & S, I truly appreciate the professional service you provide to small clients!

  I hate to let this secret get out (I'll never be able to book them again) but this is the best IT company in LA
So lovely, so smart, so elegant
Thank... read more you J&S  -- you deserve all your great success

  Need to get my Internet speeds fast all around house. J&S were total pros and had my house outlets working quickly. Even helped troubleshoot mesh wi-fi network and had great... read more hardware recommendations.

Fair pricing and super nice fellas, would hire again in a heartbeat.

  There was a miscommunication about our transactions.  
I am still working on it.   But, I can definitely state that Sean is a very honest person who will do... read more what they say and I "hope" to work with him again in the future.

  Only 5 stars!! I'd give them 10 stars if they were offered. I've lived in the SFV 25 Yrs. I've been through 45 years of rip-offs, incompetence, inexperience.

So when... read more I tell you J&S Advanced I.T. is the ONLY HONEST VENDOR in SFV, W.LA., and Ventura valley, you can rest assured that you are in great hands.

No job too big or too small.

  These guys were awesome. They responded super quick to my inquiry and came out to my house for an estimate. They were super friendly and very knowledgeable.  They recommended a... read more different mesh system then what I had been using, and we're back the next day to install. And within an hour, the Wi-Fi all over the house was amazing. I am now getting speeds I have never gotten before. They picked a solution that didn't break my bank, but gave me what I needed for my size of house. They didn't try to upsell or recommend anything I didn't need. I really appreciate their work and I would highly recommend them!

  I am so pleased with the work performed. They troubleshooted my internet issue and fixed it quickly. They also installed a boxed enclosure for all of my components so it... read more is all in one place and not an eyesore.

I highly recommend this highly professional, knowledgeable team.

  Jason helped replace the motherboard on my freelance desktop in a pinch after it was roughly handled during flying.

He was very understanding of my time-sensitive needs, considering I needed the... read more desktop running again to handle some quick-hitting timelines. This was while Labor Day weekend had everyone else turning the repair down.

Jason pulled off a miracle for me and I was able to deliver to my client because of it. Great communication, regardless if you're tech-savvy or tech-averse. Pricing is more than fair and the turnaround time was incredible.
