What my customers say:
After many hours on Google looking for answers, 45 minutes each with an Apple tech and a Microsoft tech with no solution, Jeff solved our problem in 40 minutes and with a very reasonable charge! Thanks so much! - Martha, Glendale, AZ 10/4/2016.

Thanks so much for responding and calling me back on a Saturday while on vacation. It is very much appreciated. - Mary, Peoria, AZ 7/10/2016.

Jeff arrived on time and helped me with hooking up my printer. Also cleaned up the Dell laptop, since it was operating slow and at times would stop. Jeff gave tips on password storage and also showed me some information on using the iPad. We have always been extremely pleased with his help, pleasant personality and his attention to detail. We are happy to refer him. - Raina, Scottsdale, AZ 5/28/2016.

Windows had done its update the night before, and the next morning my computer's operating system would not load. My computer was dead in the water. I need my computer for my business, so I needed to get it fixed and quickly. I called Sirius Technologies and Jeff McCormick came out the same day. He showed up right on time. He was able to get my operating system backup and running. He is friendly and professional. His prices are reasonable, and I will definitely call him again if I have any computer problems in the future. - Larry, Phoenix, AZ - 4/26/2016.

Jeff diagnosed the problem over the phone and was willing to come to the house, or bring the computer to him. He is extremely knowledgeable and has a large inventory of parts. He replaced the power supply and now the computer works fine. I believe he is fair in his pricing, experienced, and professional. I would definitely use him again. - Robert, Scottsdale, AZ - 3/6/2016.

Jeff McCormick did an excellent job on resolving problems I had after installing Windows 10. Will definitely contact Sirius Technologies in the future should I encounter computer problems. - Walter, Scottsdale, AZ - 12/15/2015.

We changed from a PC to a Mac and some files did not transfer over. Jeff took our old drive and put it in a box to access as a second computer. He also used an old data vault as a backup drive for Time Machine. He checked all our programs, explained everything very patiently.He was fair, very punctual, courteous, efficient, patient and very nice. We now know where to go for all our computer issues. - Scott, Phoenix, AZ - 11/7/2015.

Jeff, from Sirius Technologies, was very punctual and personable. He spent two hours with the computer....found many viruses and spent time helping me understand some of the basics. The computer was cleaned up and now runs like it was new. I would definitely call Jeff again with any computer issues I encounter. He is very knowledgeable and has excellent "people skills." - Celia, Phoenix, AZ - 11/1/2015.

Overall great service! Did a scan on both my iMac as well as my laptop pc. Corrected/adjusted a few issues, and suggested I install more memory on my iMac. He pointed out what to buy on Amazon, and explained how easy it was to install. He answered all my questions, and would certainly use them again. - Robert, Phoenix, AZ - 6/17/2015.

Set up 2nd network with new router. Linked printer to wi-fi network. Linked TV to wi-fi. It went very well. Service was professional. Jeff has a very pleasant personality. The 2nd network expanded our network. We are now able to access on our TV the photos and music that are on our computer. And we can now print from several computers. Overall, simply excellent. - Richard, Phoenix, AZ - 5/11/2015.

Jeff, set up and appointment with me after I purchased the "the Big Deal" on Angies List. He arrived right when he stated he would and was very professional and nice. I explained to him the problems I had been having with my computer and he was very patient with me, and understood that I was NOT very knowledgeable in computers. He took his time and explained each step he was performing as he was performing it. He ran several different tests to see how the computer was engaging. After running a different anti-virus program, and deleting programs I did not need, my computer is now running faster and more proficient than it ever has. - Vicki, Gilbert, AZ - 4/13/2015.


Hello, I'm Jeff McCormick, owner and operator of Sirius Technologies, Inc. I grew up during the personal computer revolution and have been fascinated by them since day one. I've built them, written software to power them, maintained and upgraded them for 20+ years. I realize however that not everyone shares my passion for computers and technology, so that's one of the reasons why I decided to start Sirius back in 1996. If you need help with your computer, give me a call and I will do my best to make sure you are another satisfied customer. And if you hire me, you'll also be hiring local, and have a direct impact in supporting our local economy.

Sirius serves greater Phoenix with focus in Carefree, Cave Creek, and North Scottsdale.
