How we price this for Phoenix

We take each national base range and multiply it by Phoenix's local index of 1.01:

local range = national base × 1.01

The index blends the metro's wage relativity (Phoenix metro wages for appliance technicians (BLS OEWS occupation 49-9031)) with the BEA Regional Price Parity for Phoenix, held to a sane band. Parts ship at national prices, so only the labor and overhead share moves with the metro. These localized estimates are cross-checked against 3 locally published service fees in the observed stat above — figures we show verbatim, never run through the index. The full method and source vintages are on the methodology page.
