re: A/C not cooling down: Question

If you see ice the system is starving for air or refrigerant. Period. It usually takes hours for a system starving for refrigerant to freeze; whereas, a system starving for air will freeze much quicker. This is a sealed system so if it's low on refrigerant that means it's leaking. I bought a drum of R-22 for $70 20 years ago. In May: $500. In July: $750. If you recharge a leaking system with R-22 (DuPont patented the name "freon") you are throwing money away.
