Sounds like this should be any easy answer, but not so much. In the following, I am going to assume the system or system branch/leg being worked on is a single floor of a normal sized commercial building of maybe 20-40 heads or so - not a major highrise or hotel or warehouse system with maybe 100 or more heads on a single isolatable branch, and not an oversized long run or high volume piped system - assuming normal 2-3 inch sprinkler piping,

For an empty "dry" system (no water in pipes till sprinkler goes off) can be as little as $75-150 minimum service charge for the fire protection tech (plumber in some states) plus typically $20-50 for the sprinkler head. If the "dry" system is filled with corrosion-protection special gas that can add $100-300 for the labor and gas to refill a single normal system branch or leg after the repair, depending on the extent.

For a simple, single-story wet (the normal type - prefilled with water) system (or single story leg of a higher building) if it has proper shutoff valves to isolate the section being worked on, from that $75-150 labor plus $20-50 parts range to maybe $200-300 labor - because he has to shut off and drain that part of the system first, then slowly loosen the head to finish draining off any water sitting in that section of the pipe into a bucket, change head, then bleed air out as he recharges it, and check system.

Items which can add to your cost - if the leg/head is directly connected (hardwire or wireless) to a central alarm system, meaning that unit of the alarm system has to be disabled during the work to avoid a false alarm, if the head is located very high (say over 10-12' off the floor), etc. If a "smart" self-alarming, high-pressure or foam system head then the head cost itself can run more like $50-150 - plus the labor.

If you can provide sprinkler brand and head model/part number when you call for service could help a lot - so he can bring right part rather than having to come, see what you have, then come back (so additional labor time charge) after he gets the part, you may save some time. In a commercial setting, if all heads in the building are the same (or maybe two types - open area and along wall or barrier type) might be an idea to keep a spare of each in stock in the building - though the wax fusible link type do have a shelf life and cannot be stored in a hot location.

Big potential cost addition - in some cities, especially if building has more than so many occupants in it (typically 50-100 range), is over so many stories (over fire truck ladder height - typically about 6-10 stories in most cities), then commonly he first has to get a permit from the fire department, then call them before starting work to notify them the sprinkler and/or alarm system is off for maintenance, do the work, then call them that system is back on. In high rises and high-occupancy buildings like hotels, and for high-risk places like senior living or hospital/recovery centers and schools and some hazardous materials/petroleum manufacturing/handling/storage facilities, some cities require (and charge $500-1000 for) that they dispatch one or more trucks to 'stand-by" while the alarm and/or sprinkler system is off and opened up in case there is a fire during that time. So depending on building use and occupancy and whether it is basically vacant part of the day or week, you might be able to avoid that hassle and cost by paying the repair firm overtime as needed so the work is done when the building is basically empty of people during the night or on weekend.
