What it does
The thermostatic expansion valve meters refrigerant into the evaporator coil. When it sticks, the system either starves or floods, and cooling drops off.
Why it fails in Phoenix
A failing valve mimics low refrigerant almost exactly, so a thorough diagnosis rules that out first. Paying for refrigerant when the valve is the problem is a common and avoidable expense.

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.
