What actually happens during a flat-rate diagnostic visit

"Diagnostic fee" means different things at different companies, and the ambiguity is usually where trust breaks down. Here's exactly what ours covers and what the visit looks like from start to finish, so there's nothing to guess at before a technician shows up.

Before the technician arrives

You'll get a text with the technician's name and a live ETA — not a four-hour window, an actual tracked arrival time. The flat diagnostic fee is quoted on the phone before you book, and it's the same number on the invoice. Nothing about the visit itself changes that number.

On site: the actual diagnostic

• Inspection. The technician checks the system's electrical components, refrigerant pressure, airflow, and any fault codes the unit is reporting.
• The reading. Whatever the actual fault is, you get shown the number — a gauge reading, a fault code, a measured pressure — not just a verbal explanation of what's wrong.
• The written quote. Parts, labor, and timeline, in writing, before any repair work starts. If you approve it on the spot, the diagnostic fee is credited toward the repair.

What we won't do

We won't find "one more thing" once the panel is already open and use that as leverage for a bigger sale. If the diagnostic turns up a second, unrelated issue, we'll tell you about it and quote it separately — you decide whether to address it now or later, and the choice doesn't affect the original repair.

After you approve the repair

The technician does the work, then verifies it with a gauge reading before packing up — the same standard we hold every repair to, not just the ones being watched. You get a copy of the invoice with the before-and-after readings, so "fixed" means something you can actually check, not just something you were told.
