Richard was very helpful in diagnosing the problem with my wife's laptop. He went out of his way and had it fixed the same day. Upgrading the hard drive made it faster and my wife and I are very much pleased. Thank you very much, Richard and Aurora, for your great service.

This place is great. No BS. You deal with real people and they get the job done. I've taken two laptops to them, and both were fixed by the next day.

My HP laptop froze up, nothing I tried would work. I took it to Caltech and 2 hours later it was up and running perfectly. Excellent service at a very reasonable price. I highly recommend them.

I was about to give up on my laptop because it ran so slowly but Richard and Aurora got it back into working shape and it has never run this well. They are very knowledgeable and their customer service is unmatched. I am beyond satisfied with my experience with them and wouldn't go anywhere else.

Richard, Aurora and everyone on the Caltechsys Team are quick studies of the challenge at hand and able to diagnosis and repair software and hardware problems. I've use this team for years and never been disappointed.

Richard was exceptional. No technician would spend approximately 30 to 40 minutes of their own time helping me receive sound on my PC. He did this out of his own generosity. Very few would spend did this much time with a complete stranger fixing the computer issue. I would recommend this technician. He is honest and trustworthy. He truly will not stop until the problem is 100% solved. He cares about helping the customer. He truly enjoys his job. This type of company is a rarity. One that values complete satisfaction over compensation.

Fixed a wifi card issue I was having. Great service. I had a couple other problems prior to this they couldn't fix (in another computer) and I wasn't charged when they couldn't fix it.

I had an issue with my lap top and helped me over the phone. Great customer service, this was on a day that were not open and I did not realize that. They picked up the phone and helped me out. Very thankful

Phenomenal service by Richard! He was able to help us in a last minute time crunch with a domain issue. Worked after hours to ensure our business operations weren't effected. Highly recommend!

A great group of guys that have deep IT knowledge and experience. The business is located out of the owners house but don't let the looks be deceiving. They know what they are doing and they do it well. I recommend to anyone who might be trying to the wait at big tech stores like Best Buy or micro center for pc repair. Odds are you'll get your pc fixed much faster and for much cheaper because they won't recommend replacing parts you really don't need. 5/5

I had a problem with my the power supply in my raid and when the manufacture told my only option was to replace it I took it into Caltechsys. Within a few days Caltechsys had me up and running again. The team here is very knowledgable and their rates are extremely reasonable and fair. I highly recommend Caltechsys for any computer repairs.

I had a virus on my computer and I took it to best buy who wanted to charge me hundreds of dollars to just take a look at it. Found these guys on an internet search and they were able to clean up the computer within a couple of hours for half the price! Very satisfied and charming group of individuals!

Words can't express how thankful I am to have worked with Richard in diagnosing my Dell Inspiron 6000. He assessed the situation and realized it was something he could work on remotely. Richard was very pleasant to work with. I desperately needed to use my computer and thanks to Richard's patience and support we were able to get it up and running.

He went above and beyond to make sure I was squared away. This is the kind of person/team/company you want to do business with. I wish there were more Richard's in the world who take pride in what they do and truly enjoy their profession!
