What it does
A leak search finds where refrigerant is escaping, using electronic detectors, dye, or nitrogen pressure testing. It is diagnostic work, not a parts repair.
Why it fails in Phoenix
Constant summer runtime stresses coils and fittings, and small leaks show up as a system that can't keep up on 110° afternoons. If you have recharged twice, price the leak search — recharging without fixing it is renting cold air by the pound.
What a fair quote includes
- Diagnostic and testing
- The part, new — ask for the part number
- Labor by a licensed tech
- Parts and labor warranty in writing

Questions
What should the quote include?
A fair quote covers the diagnostic visit, the part, licensed labor, and a written parts-and-labor warranty. Ask for the part number — with it, the price is checkable.
Why do quotes for this vary so much?
Brand of part, warranty length, after-hours timing, and how hard your system is to access all legitimately move the number. That is why we show a range rather than a single price.
Is the diagnostic fee extra?
It varies. A fair quote credits the diagnostic fee toward the repair if you approve the work — ask before the tech starts.
