Plus materials: the window unit itself ranges widely by brand and glass package. Always get the model quoted.
Typical labor: 2–4 hours at $55–$118/hr billed.

That assumes insert replacements, no structural changes; full-frame swaps take roughly double.
Typical labor: 16–32 hours at $55–$118/hr billed.
