AC cools for a little while then airflow stops
Our upstairs unit starts off cooling and seems to work like a good working AC unit, but after some time, maybe 30 minutes, the airflow stops. We can still hear the unit running, but turn it off immediately.
I change the filter regularly and vacuum the vents, so it should be an issue with blockage. Any idea what the issue could be? Is it possible it could simply be low on freon? When this happened on our main level a few years ago, it wouldn't cool at all. This is different. It cools initially, but then the airflow stops.

There are two units..... inside and outside. Which one do you still hear running ?
No airflow signifies a problem with the blower in the air handler, especially icing up like T mentioned.
A low refrigerant issue must be handled by an HVAC tech as he has the license to dispense refrigerants.

Ok. So if you hear the blower running but don't get any air flow.... that would be the coil icing up. If the airflow feels strong when first starting the A/C..... then you need to have the refrigerant level checked.
