About Us

Relia-Tech is fundamentally different from other computer support firms because of our passion for assisting our customers.   Our local office enables a fast turnaround time on the purchase, installation, and support of computer and network products. We believe in and use fair and honest support and pricing polices. Finally, we are constantly working to improve the services we provide and further educate and train ourselves. At Relia-Tech, we work with you not for you.

Knowledgeable, highly trained technical staff

  • Certifications in PC repair, network installation and support.
  • Ongoing training in state-of-the-art technologies.

With our Middleton office location and Technicians with the ability of working remotely from anywhere, Relia-Tech is tightly integrated into the local community. This ensures that if you have a problem we can arrive quickly to provide a personal solution from a familiar technician.

Conveniently located in Andover, MA.

  • Serving Eastern/Central Massachusetts and Southern New Hampshire.
  • One standard round-trip fee for site visits.

Most clients hire us because they don’t have the knowledge to maintain and support their computer systems or networks. We never take advantage of this lack of knowledge to charge higher prices or sell extra services. Our goal is about becoming your trusted technology partner and building a long-term relationship with you. We work hard to earn your trust, respect, and business.

No Tricks or Games.

  • Honest, reliable services.
  • Focus on long-term relationships.
  • We strive to be your technology partner, not just a technical support company.
