Why would a smoke alarm go off if there’s no smoke?

It’s not chirping like a battery is low. It’s not a carbon monoxide detector.

Is it ghosts?

It's possibly a heat detector if it's in a kitchen area.

Because it's a shitty smoke detector.

Get it?

They have a life span on them. Check for a date.

my alarms were so sensitive, I had to take them down.
I hope my house doesn't burn down.

ETA: They were brand new as well. (New House Brag)

Dust on sensor. Vacuum or canned air.

My smoke alarms often go off when I run the heat for the first time...dust burning in the furnace trips the smoke alarms.

most are dual purpose and also read carbon monoxide as well, doing a lot of cooking can set those off

other then that, could just be a lot of dust on the sensor so take it down and blow it out with air hose or can of air

I had this issue too. As the wife and I were upgrading things around the house, we purchased some brand new smoke/carbon alarms. Install and test was easy. After about a month, that fricker starts going off in the middle of the night. I cleaned it out, re-installed. Next night, same thing.

frick that. We don’t have a gas leak, otherwise I’d be dead by now.

Had the same thing happen at my house. Turns out those things have a lifespan and you have to replace them every now and then.

They get more sensitive as time goes on and they get “dirtier”

I replaced mine with Nest Protects - some of the best money I've ever spent - they are so much better than the typical smoke detector and carbon monoxide sensors in them too.
