5.0 Nial Washington Google Review

I had been having trouble with my old laptop. I reached out to SD IT Service for assistance. Alex spent time checking my laptop & informed me that the problem was none other than a Windows OS error. I could have gotten ripped off, but he chose honesty instead. I am certain to return to them as a customer because of their transparency, and I will recommend this place to all of my friends, and coworkers.Excellent work, gentlemen! Well done!

Response from Company:

Thanks Nial for choosing SD IT Service.

5.0 Lisa Fowler Google Review

SD IT Service provides excellent services! In the past few days, my computer has been running slowly, and it was getting worse day by day. After Alex diagnosed my computer and suggested upgrading my hard drive, I had my old HDD replaced with a solid state drive. Also, he helped me remove spyware from my computer, so I now have a much faster machine!

Response from Company:

Thanks Lisa for choosing SD IT Service.

5.0 Rachelle Hubbard Google Review

I had some terrible experiences before with computer repair centers. That is why I was confused whether SD IT Services would provide me with quality service. They proved me wrong. Their support desk was very helpful. They have knowledgeable technicians who were able to find a solution to my laptop's problem. Service charges are very reasonable. The following day, my laptop was ready. Highly Recommended.

Response from Company:

Thanks Lisa for choosing SD IT Service.

5.0 Cor Meems Google Review

The talented and dedicated staff at SD IT Service are very reliable and will get the job done no matter what. They work as a team to identify the appropriate person to solve a problem, and are willing to escalate to expedite a solution. Their support staff respond quickly to all of our requests and remain in regular contact until the issue is resolved. I have referred them to a variety of business associations and will continue to do so.

Response from Company:

Thanks Core for choosing SD IT Service.

5.0 Victoria Johnson Google Review

SD IT Servcie team is extremely valuable to us, when IT comes to reliable IT support & services . With their extensive range of talent and expertise, we don't need to hire our own in-house IT staff to manage our IT needs. Thus, all our employees can focus on growing our business.

Thanks Victoria for choosing SD IT Service.

Alex and the company as a whole was very professional, very patient, I could not be happier, everything was perfect and they made sure everything was running well. I would highly recommend them.

5.0 Joe K. Des Plaines, IL

These guys are great! OS ITservice has been our managed IT provider for over 3 years now. They helped us build our office out and have been supporting our server, computers, and team members ever since. They are always super quick to respond to any problems and meet with us regularly to review our business objectives and suggest any tech improvements.

5.0 Alex P.

Totally love these guys.. oops, does that sound creepy. But, hey, their IT/tech support is the bomb! Alex is the best and is always in a great mood. Dig it!

5.0 Dale M. Johnstown, PA

I can't recommend more thorough and professional I.T experts than these guys. They not only know their stuff exceedingly well, but they take it a step further by having sensational customer service and a genuine approach towards each individual customer's needs.

5.0 Alexis E. West Valley City, UT

Alex and the OS ITservice team have been partners with our company for a few years now. I find them to be one of the leaders in providing IT services and 100% focused on delivering skilled and personalized IT management and support in the San Francisco Bay Area. Alex's also a great guy and a man of his word. Would highly recommend.

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
