Called around 3pm on a Monday desperate for a fix on the power supply for my computer. Chris got me in and ran diagnostics and repairs in less than 3 hrs so I would have my computer for a game release the next morning. He did a fantastic job and was very knowledgeable for what we needed. His bubbly personality really made it easy to feel comfortable leaving my computer for repair. I highly recommend him for any services in the future. ​ read more

Cesar is incredibly passionate and caring, providing exceptional service, knowledge and advice. I highly recommend him for any of your tech-related needs. EXCEPTIONAL SERVICE I requested assistance with my recently purchased refurbished Acer Predator desktop tower because I kept randomly receiving blue screen messages and boot device error pop ups upon start up. Within a minute of submitting my request, I received a response to schedule a time for him to come and work on my computer the following day. We scheduled for 2pm, but his earlier job was super quick so he offered to start ahead of schedule, which I was not expecting. Upon his arrival, he was able to work out the most likely problem within minutes. He installed a few open-source programs to look into the status and manufacturers of my hard drives, giving me insight to the brands of the components that my system had and how cheap and poor quality they were. That said, he said the rest of the computer was really good and that my setup was perfect aside from these poor quality hard drives. After giving his recommendations, he mentioned that he had hard drives so I asked if he could install a better quality one. Within 15-20 minutes, he opened my desktop tower and had it installed. The bulk of the time was spent re-installing the operating system on this new hard drive because he discovered Acer had blocks in place where it would not read the drive even though there was actually nothing wrong. Cesar discussed that newer technicians may have blamed this problem on the motherboard, but he was able to work around it and get it installed. He was also able to re-install missing drivers. He mentioned earlier that I had Windows 11 Home edition, which did not perform as well and wasn't nearly as secure so he also installed the Pro version on this new system. After this new hard drive was fully up and running, he showed me the performance metrics of my computer to show how much faster it was. The CPU usage decreased by half and memory was far more efficient. After this point, my computer no longer crashed or gave me boot device errors, which I was most happy about. The price of around $260 was very fair, considering he installed a higher quality SSD, upgraded my Windows edition to Pro, installed other premium hardware, and provided incredible advice and knowledge I wouldn't have even thought to ask about. He also provided a 1 year warranty on the hard drive in case problems arose. GOING ABOVE AND BEYOND As an added bonus, he also identified and fixed numerous other problems. He noticed that my mouse was malfunctioning and recommended the best brands and steered me away from Trend Micro and installed Avast, which also made my computer perform and respond better. He added icons to my computer making it easier to access the control panel and other menus, and installed a better file search method than the one built into Windows Explorer, making it far more efficient to locate files than waiting for them to load. MAKES THE TIME FLY FAST While Cesar performed his work, he shared many entertaining stories along with his tech insight. This really made the process more smooth and enjoyable than sitting there waiting for him to be finished. I enjoyed talking with him. I highly encourage you to be open to conversation with him during your repair time. It will make the experience so much more meaningful! Cesar even talked about life with me and gave me career advice and guidance, reminding me to always keep my paths open and not lose sight of my own passions and desires, my true self! CONCLUSION I was nervous and tentative requesting service from a technician. I've heard many stories about people being scammed or conned, or still having their problems after funneling in so much money. Cesar put all of those worries to rest immediately when he stepped through my front door. From the get-go, he was incredibly friendly, kind, intelligent, knowledgeable, and efficient. I was expecting a boring, monotonous repair appointment. He turned it into an experience I won't forget, sharing his wisdom, insight, and expertise, his incredible stories, his compassion with me. Cesar is not just an incredible technician, but an incredible person to meet and speak with. Please consider Cesar for all of your tech or website needs! read more

I called to inquire about getting my old laptop top in working order and the gentleman that answered asked me a few questions and advised me to get a used ipad or computer for the price it would cost to repair mine. He could have easily taken my money and fixed my laptop but the fact that he advised me to just get something newer for the same amount of money lets me know what kind of business this is. definitely will be calling back if and when I have any tech issues. Thank you ! read more

My hard drive died right in the middle of a big project. After calling a couple of repair companies listed here who told me I'd have to bring the tower in to their shop and leave it, I called Cesar. He came out within a half hour, and spent almost 3 hours. He quickly diagnosed the problem, and installed a new hard drive and made a number of other improvements to my computer that I wouldn't have thought of. He also worked on a second computer that needed help. His price for all of this was very reasonable. Cesar made sure that all my files were transferred to the new hard drive, and explained everything very clearly. I needed some help the next day, and he worked with me from his office, remotely accessing my computer. I won't hesitate to call him again, and I've already recommended him to friends. What a relief to have someone I can call about computer problems! read more

These guys were awesome! Super helpful, very responsive, knowledgeable, and fun to work with. I purchased a used gaming system and it needed some drivers updated and they got it done quickly and efficiently for a VERY reasonable cost! Thanks Cesar & Chris, I will be calling you back! read more

Fast response and reliable. For mobile service pricing is reasonable. Was prompt to scheduled appointment. Explains well the diagnosis of the tech issues. Definitely recommended. read more

Cesar spent a good two hours trying to bring back my MacBook Pro back online with current programs he bought with him. But nothing would bring this 5-year-old computer back to service. So he swapped out a newer MacBook Pro he had in his truck and transferred all the info from my ailing Mac to it and sold me the newer Mac for a far lower price than I expected to pay. He was very friendly and easy to work with. I give him my highest recommendation. read more

Had a fan on my PC go out. Had my PC fixed and back to me same day in a few hours. Great service and affordable. Highly recommended.

Caesar, was quick to diagnose the problem over the phone; made an immediate appointment for same-day, in-home service and arrived on time; fixed the problem (corrupted OS) and recommended additional measures that would make my iMAC viable well into the future. I'm awaiting a parts order from Amazon and will have him back as soon as possible to install my upgrade. I highly recommend him and will reach out directly to him should I have any future needs. read more

The keyboard on my labtop stopped working one night around 6:30pm and I called the business and Cesar answered the phone. I explained my issues with my labtop and He was able to very quickly figure out the root cause and tell me exactly what needed to be done and the cost was very reasonable! I was able to drop my labtop off the next morning and it was fixed within 1.5 hours, super quick! He also found some hardware issues so he replaced my computer hard drive and was able to place back all my old files back onto my computer after replacing the hard drive (was very happy to not have to lose any of my files). After fixing my labtop, he even followed up with me later in the day to ask how the labtop was working to make sure all was good still. Would highly recommend and I will use this company again whenever I have computer/labtop issues! Super quick in response, is knowledgeable, and affordable! read more

I had been so frustrated with how incredibly slow my laptop was, and knew it needed work and the drive upgraded...I researched and found Cesar at 24/7PcTech who had great reviews. He fit me in right away. He let me know my laptop was a good one, replacing my drive and making some very necessary upgrades and changes. I am so pleased with the results. Cesar is very knowledgeable and makes sure you have what you need, the best of it, and nothing more, and his prices are really fair.

So far so good. Caesar was very accommodating on the phone and quoted me a GREAT price! When my new PC arrives, he assured me he would do EVERYTHING from soup to nuts. I'll update my review after services are complete. UPDATE: Caesar is AHHHMAZING! Dude knows his stuff!!! He came the same day I called him. Caesar was super nice and professional. He set up my new PC, put in the hard drive from my old computer into the new one, made sure I had access to my 2 external hard drives, ensured I had access to my programs and printer, set up shortcuts on my desktop so everything is easy find and access...basically EVERYTHING from soup to nuts. His price was super reasonable! Caesar, you are now my go-to guy for tech issues. Thank you soooooooooooo much!!! read more

I started off with wanting to clean my pc. After I finished cleaning it, it won't turn on. Geeksquad tried to get me to buy a new machine, but I didn't want to. To make matters worse, I accidentally dropped my monitor. I found 24/7PcTech. I requested a quote and Cesar reached out to me 5 minutes later and was able to come look at my PC within 10 minutes. He noticed that I had an old hard drive and replaced it with a new SSD. He was very informative and explained the process very well. He was done within 30 minutes. My PC was like new again. I highly recommend this company. read more

Cesar responded to my inquiry immediately and came to help within a couple of hours the very same day! What a pleasure to meet Cesar! A very kind & generous person, he explained everything in language I could understand. He made sure all my data was transferred to my new laptop, with emphasis on security. I highly recommend his services. read more

I normally do not write reviews, but the service I received from Cesar was so exceptional that I must write one. My PC stopped fully booting to the desktop on Wednesday and after eliminating some of the potential issues I gave up, as hardware troubleshooting is a real pain if you don't have spare parts lying around. I searched for a PC repair place and ended up reaching out to 24/7PcTech. Cesar answered and said he would be available to come out to me on Thursday, which was convenient because no one likes to lug their heavy PC around. I consider myself tech savvy, but Cesar is definitely on another level. Cesar was very patient, thorough and determined to pinpoint the problem. Once we started troubleshooting we determined it was my SSD and AIO, I asked if he would wait for me or even come along to Best Buy so that I can pick up the replacement parts, replace the potential dead parts and have peace of mind that the problem was fully fixed. Once we returned, Cesar even helped me disassemble the faulty parts and put the PC back together. I want to pause here and emphasize that level of service absolutely stellar and is unprecedented in my experience. would stop here, but I have not shared the best part of this whole experience. After all was said and done, the job ended up being around 5 hours total. The best part, he asked me to quote a reasonable price for the time and labor spent. If you are having tech issues, look no further. 24/7PcTech is the one!! Highly Recommend!!! read more

Thank you, Chris, for keeping me informed step by step and for fixing my mom's computer. It is greatly appreciated!

Second review- Just got my PC back and I had issues getting my graphics to pop up, it just black screened on me and within 2min of sending a text to the tech, he guided me through how to get it fixed and I never even had to take it in. Couldn't be happier with the customer service and proof of knowledge. read more

What a phenomenal experience! My laptop crashed and burned and I needed to replace it ASAP. My husband started looking for refurbished laptops in the area and came across Cesar Alexander. Cesar shared that he had a few options available and shared that he could deliver that evening. After doing research on the laptops he had that were within our price range, I looked up the reviews on the laptop and they stated exactly what Cesar shared with my husband. After that we checked out his reviews and saw that he has a 5 star rating. Cesar delivered my new laptop and educated us on many different topics. He definitely is our new tech guy and we completely agree with everyone.....CESAR IS 5 STAR ALL THE WAY, IN SERVICE, IN PRODUCTS, AND PROFESSIONALISM!!!

I would 100% recommend these guys! My computer suddenly decided to died on Feb, 5th, I did a walk in the following day. Chris swiftly diagnosed the problem within an hour, showed me where I can get a replacement part nearby, and swiftly replaced and installed the new GPU. In just three hours, my PC was up and running again. I highly recommend their services to anyone in need, and I'll certainly return if I encounter any future computer troubles that I'm not able to fix myself. 10/10 service. P.S. Their office is the white cubical in the same lot as the mechanic/gas station, Chris owns the mechanic shop and works out of the cubical for PC repairs. read more

Very responsible and on time very good service. Thank you much upfront in Street Foward

First time customer. My MacBook Pro had been having crackling sound .I had a phone consultation with Cesar and immediately diagnosed the repair needed plus since the system is going to be opened and it is 9 years old, he had suggested the replacement of the battery also. He was very pleasant and upfront with the charges. I did get the supplies from Amazon as per his recommendations Chris the technician who repaired it is very knowledgeable , careful and thorough. He had me watch while doing the repair and even was going through the procedure while doing it. He is pleasant , I felt reassured that my lap tap is in good hands. I fully recommend this repair shop and will definitely use their services if there is a need . I was charge for labor $125 for the replacements of battery and speakers. read more

PLEASE read. I made the mistake of purchasing a computer from this guy. My husband and I purchased a computer from him because he was known for helping my father-in-law for IT issues at my father in laws place of business. First, Caesar and I spoke on the phone regarding the computer and later my husband purchased the computer from him. When my husband and I first tried connecting the computer, it was not working. This man was notified, and we were advised to meet him, and he would fix it. Which we did. However, we brought the tower home for a second time, and it still wasn't working. At this time, I thought it was the connection cords, so I purchased new cords through Amazon and even bought a new monitor. Unfortunately, these purchases did not help. He was notified once again. We were told to leave the computer at my father in laws place of business and he would pick up. A couple weeks went by, and we hadn't heard from him. I sent him a follow up text and we went back and forth. I attached the text chain below. I cannot believe the responses I was receiving. He also says I'm harassing him, which is complete BS. Fast forward, he did replace the tower. However!! It was replaced with an old computer with some components not working. I literally laughed when I seen it. I took it as a loss. I think the texts below speaks for themselves as to what kind of businessman this guy is. Please think twice from conducting any business from this guy/business. I've learned my lesson. read more

I bought HP laptop for a friend which needed repair shortly after it got infected by her niece. I went on Yelp to find repair place in my area. I knew I didn't want to use geek squad. I was impressed by description of & reviews for 24/7PcTech. I was impressed talking on phone with Cesar when I asked why I should choose his repair place. I continued to be impressed when actually being with Cesar and watching him do the repair. He explained what he was doing and why because I said don't do anything not necessary to charge$ extra. I asked for good antivirus software. He advised what other people told me. And he installed it. He answered all my questions seeming honest and not evasive. My friend is now a very happy camper with a laptop working like new. She's so thrilled "No pop ups!" So, do I recommend 24/7PcTech& Cesar! Absolutely! 6/5 read more
