Resolve Persistent Smoke Detector False Alarms

I need an experienced electrician or fire-safety technician to re-install 3 of my home’s smoke detectors. They were malfunctioning so eventually we had enough and yanked them from the ceiling. The devices themselves aren’t showing low-battery lights, so I suspect wiring, dust, or sensor calibration could be at fault.

We still have the detectors, so you'd just need to place them back on the celing and possibly rewire/fix the wiring, which I can send pictures of.

Deliverable: fully functioning detectors that trigger only under real smoke conditions, plus a brief summary of what was done and any maintenance tips I should follow.
