Diagnosis that pays for itselfA/C &
Heating

Every car takes a different charge. We diagnose exactly why yours isn't cold, and that diagnosis becomes part of the repair — not a separate charge on top of it.

THE DEAL, UPFRONT

Diagnosed first, then applied to the fix

Every car that comes in for A/C gets a full system diagnosis before any repair goes forward. We find out precisely what's going on and why it isn't blowing cold.

Diagnostic work is charged by the job, not by the hour, and it goes onto the same invoice as the repair. You're not paying twice — you're paying to find out what's actually wrong, and that amount is part of what the job costs. What it runs depends on the fault, so call and we'll tell you before you commit to anything.

WHY DIAGNOSE FIRST

Every car takes a different charge

Every car takes a different amount of refrigerant, and newer vehicles take a different type entirely — R-1234yf instead of the older R-134a. Topping a system off without knowing the spec or the underlying fault is how A/C money gets wasted twice. We charge the system by the book, to the gram, after we know why it failed.

Heat not working instead? Same approach — diagnose the cause, then fix that.
