Is there a way to tell if my ac unit is working properly?

Yes, you can check your air conditioner's performance by looking for any of the following signs: 
1. A cool breeze coming from the vents 
2. Air blowing out of the vents evenly and quickly 
3. No visible dust or debris in the air vents 
4. No noticeable temperature difference between the two sides of the thermostat 
5. The compressor running regularly 
6. The fan turning on when the system is turned on
