Frequently asked questions
What areas do you serve?+
We serve homeowners and businesses throughout Fayetteville, Peachtree City, and the greater Metro Atlanta area, with remote support available nationwide.
Do you support both residential customers and businesses?+
Yes. We provide enterprise-quality service to both — from a single home PC to fully managed IT for multi-location businesses.
How quickly can you respond?+
Most residential issues are diagnosed same-day. Managed IT clients receive SLA-driven response with 24/7 emergency coverage.
Is remote support secure?+
All sessions use encrypted, permissioned tooling with full audit logs. Nothing happens on your device without your approval.
Do you offer one-time projects and ongoing contracts?+
Both. Many clients start with a project — a migration, a network rebuild, a security audit — and transition into a managed agreement.
