Who do you hire to fix defective hard wired smoke detectors

Smoke alarms sound for no reason and we can't shut them off

Most likely not sounding for no reason - they could be sensing chemicals or fumes you can't sense, they are ones with a fixed life (like 5, 7, 10 years) and the microchips have decided that time is up (will usually but not always have replaceable pull-out combined sensor/battery tray), or they are interconnected and one of them has a dead battery or dust in the sensor, which makes all inter-connected alarms go off too.

Much more detail on troubleshooting inter-connected alarms in the prior questions with answers linked below this answer (ignore the alarm-system connected question). Remember when messing with them that they have 110V line feed to them, so don't go sticking your fingers where they should not be.

BTW - you said "defective ... detectors" - the fact multiple ones are going off makes it VERY likely that it is one of two or several inter-connected alarms going off, andwhile it is possible one is defective, it is far more likely one of the reasons above. Do not disbelieve them.

An Electrician can solve your issue - also a Handyman if just dust in the sensors or cartridge needs replacing.
