Ice just flew out of my vents

[gregk24]

2012 Honda Accord. I’m currently sitting in a parking lot waiting on our food to be ready (delicious local food truck that serves Chamorro quiz one). The car has been running for about 45 minutes straight with the A/C on “full blast”. Suddenly I heard a crackling noise then seconds later felt debris land on me. I thought maybe it was foam from the blend doors or a leave that somehow made it past the cabin filter and decomposed before flying out. But no. I looked down and saw small shards of ice on my arm.

I’ve never had this happen before. Does this spell impending doom? (Kidding).

I've seen fog come out of the vents (obviously not in the desert) but never ice crystals.

Under charged, freezing up.

I had ice coming out of the vents on an older Subaru.

This. Get your A/C system checked for coolant charge and leaks. That's the first sign your A/C is about to go.

Parents 2003 Forester used to freeze up all the time.

Check your air cabin filter and make sure it is not clogged up.

A freezing evaporator usually means lack of air flow or a low charge. Don’t expect leaks, they normally lose a little refrigerant over the years.

I’ve seen ice come out of the vents of my buddy’s dad’s 88 Corolla when we were younger.

It's not cycling if it has that system. If it's a variable compressor it's stuck on full

Not my baby! Every year I say, “5 more years”. I can’t afford a new one anyway.

It’s not variable. Not sure if it was cycling during this episode or not. From what I recall it’s not uncommon for the compressor to not cycle when under max use.

Also of note, the ac was ICE cold this whole time.

It it very humid?

He's in Florida! Probably 90% humidity!

It it very humid?

Yes, extremely. Why?

 

[JavierH19]

Propane torch the air vent. That'll teach him who to not blow ice on.

 

[Chris142]

Yes, extremely. Why?

The evaporator gets very cold. Any moisture in the air will stick to it and freeze. It's supposed to self regulate that but might not be able to if it's extremely humid.
