Is there a common reason for air to not be blowing cold besides low coolant levels?

It just doesn't seem to be keeping up even with temps only in the 80's.

If it's running outside, feel the small copper line. If it's very hot, wash outdoor unit with garden hose. Mail me $100

This just happened to my AC the last couple of days. Was wondering the same thing. Have AC tech coming over tomorrow. Hope it's just a coolant issue. Happened all of a sudden. I can feel the air blowing and it's not cold like normal, but not hot.

if it is not keeping up today, it probably isn't cooling at all...

turn the thing on and go outside...fan should be running....

check two copper lines coming out of the outside unit...large one should be cold and sweating and small one should be almos too hot to touch....

90% chance you need freon...

Freon could be low, or you could vacuum out your pipes (one near your fan and one near your ac unit) and pour bleach in the pipe near your ac unit

The air blowing out of the top of the fan on the unit outside should be warm also, if it's working right.

you likely just need a capacitor if you aren't low on coolant. It's an inexpensive part too.

I don't know but I have an AC guy coming this evening to change out my fan motor for the second time in two weeks. I'm buying a window unit today for backup I'm sick of it
