Free Diagnostic Offer — FAQ
Do I really get a free diagnostic?
Yes — when you approve a repair order with 4 or more labor hours, we waive up to 1.0 hour of diagnostic time on that same order.
What if my repair takes less than 4 hours?
If the approved repair is under 4 hours, the standard diagnostic rate applies. We’ll always quote before you decide.
What does your diagnostic include?
A full-system scan, fault review, and targeted tests appropriate to the symptom (e.g., live data analysis, bidirectional tests, smoke/pressure tests). You’ll get a written plan.
Will you just read codes and tell me to replace parts?
No. Codes are a starting point — not a parts list. We test to confirm the cause before recommending repairs.
How fast can you fit me in?
Often same day. Call (830) 428-4223 or book online.
