Wade Cantrell has assembled an excellent group of very knowledgeable computer specialists. I have been bringing to them my computer issues and problems for several years now, and have always been satisfied with their help. From my experience they stand behind their work and stay with any problems that arise until they are resolved. I highly recommend their services.

Very positive experience here, my Dell laptop wouldn't start up...called Cantrell's, brought it in, they explained everything clearly to me, they fixed it, put in a new hard drive, and saved all my data ...whew.
Excellent communication and customer service, they called and kept me updated on the repair progress, and when I brought it home I had to call them at least five times because I couldn't figure out simple things, lol. They were polite and professional and extremely helpful, and now I have my computer back. Highly recommended, support our local businesses!!
Thank you Cantrell's!!

Wade Cantrell, owner of Cantrell’s Computer Sales & Services, is a great person and wonderful business owner. As such he hires excellent people.

The microphone on my computer has never worked. As video meetings become the norm, my work-around doesn’t always work and I really need a functional mic. Wade set up a virtual support appointment with one of his techs. The tech was prompt, helpful, polite, and unsuccessful. I needed to take the machine in. We easily made an appointment, that I had to reschedule, and I continued without a microphone for a couple more days.

While I had a half-hour appointment slot, I assumed that I would drop off my computer and hope to hear from the tech before the day was out. I was greeted by a different tech – also friendly – who started the thing up and in about 10 minutes got the mic working. Turns out we needed a little trial and error along with a hands-on approach.

By the time my half-hour appointment time was done, my computer was fixed, I’d gone to the gas station around the corner to fill my tank and tires, and was on my way home!

Every time I interact with Wade or any of his guys, I have an excellent experience.

My computer went down for the count and I was frantic to get it fixed. Called Cantrells and their technician Nathan took my call and came to my house within the appointment time frame. He took the computer back to the shop for diagnostic testing which indicated a blown motherboard and other issues. Ultimately I had to purchase a new computer that DAY and had to have all files transferred from old hard drive. Nathan completed the task of cloning the drive and returning the new computer in less than 5 hour period! Outstanding service and unbelievably quick turnaround time! Thank goodness for people like Nathan who know their trade and provide PROMPT and RELIABLE SERVICE.

February, 2018 - Received prompt, courteous and knowledgeable service at Cantrell's. Vance and Nathan were very helpful and took the time to answer my many questions. Vance was able to recover data from my hard drive and set me up with a new computer at a very fair price. Highly recommend them for all your computer needs!

I have been dealing with Cantrell's for about a decade now and they have always lived up to my expectations. Always friendly and knowledgeable, and best of all...FAIR! Thank you Jordan and Nathan on my recent upgrade to Windows 10 for my laptop. All good, and I will be taking in my desktop PC to them next for the same conversion.

I have used Wade's computer maintenance services for nearly 20 years for desktops and laptops. He has also custom-built a desktop for me. In all these instances his team have successfully cloned for transfer, or recovered for transfer, whole hard drives of files, photos and emails. He has recommended and implemented many very serious hard-drive and memory upgrades along the way. His staff are always courteous and prompt.....and available for the odd phone-in question, even remote access and fixing while I've been traveling. All in all, highly recommendable indeed.

Spoke with Wade, the owner, today on the phone re: my laptop suddenly not turning on. He was more than happy to walk me through a troubleshooting procedure that worked. I offered to pay for the help but he declined to accept, and even offered some additional advice such as backing up all files and docs through cloud storage or storage device. This is great customer service and professionalism that all businesses should emulate.
