What it does
The contactor is the heavy-duty relay that switches high voltage to your outdoor unit every time the thermostat calls for cooling. When its contacts pit or weld, the unit either won't start or won't shut off.
Why it fails in Phoenix
Phoenix systems cycle hard from April through October, and every cycle arcs across the same contacts. Dust and monsoon grit accelerate the pitting. It often fails in the same visit as the capacitor.
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
Worth knowing
- Often fails alongside the capacitor — a fair quote checks both.
- Pitted contacts from summer cycling are the usual cause.

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.
