Not sure whether to repair, upgrade, or replace?

That is exactly what diagnostics are for. We can check the computer, explain what is wrong, and tell you whether repair, upgrade, or replacement makes the most sense.

Diagnostic fee: $65. If you move forward with the work, the full $65 goes toward the job. If you decide not to proceed, you only pay the diagnostic fee and nothing more.
