Some AC's have auto shut offs for when things go not so right... some don't.

Depends on make, model of the unit in question.

If the AC in question doesn't have these safety devices it runs until the breaker trips or it catches fire. (Usually the breaker trips before fire breaks out)

But I have seen a few units over the past 26 years -- that caught fire and burned internal components.

Cheaper units are those without safety shut offs. All manufacturer's make cheap models... so branding means very little.

I service the Katy, Texas area.

Hi there, some HVAC units have the auto-shutdown function, but others do not. If your AC does not have the auto-shutdown function, here are some ways you can stop your AC from overheating:

- Clean and replace AC filters often

- Clean your condenser coils regularly

- Check for low refrigerant levels

I would recommend calling an HVAC expert to come check out your unit if none of these solutions help!
