Long punch lists and projects with no fixed scope. Billed by the hour, so the total depends on how long it runs.
What the lower end buys
You get two or three battery units replaced or added. Old ones down, mounting plates set where the alarm belongs in that room, batteries in, each unit held down until it sounds, and the dead ones carried away. Standard ceilings, everything within easy reach.
What the higher end buys
A whole-house set of hardwired smoke and carbon monoxide combination units, interconnected so one alarm wakes the house, belongs at the high end. Anything over a stairwell or a tall entry needs the ladder set up with care, and the full set gets tested once the last unit is in.

Biggest price driver
Wiring type decides this. Battery units screw to a plate and go up one after another. Hardwired units come off a harness that has to match the new model, and an interconnected set is only finished once every alarm in the house answers a single test button.
How to keep your smoke detector installation cost down
Replace them all in one visit rather than chasing a chirp room by room, since detectors age out around the same time. Tell us which ones are hardwired, and move furniture clear of any unit that sits above a stairwell.
