This is from 2016, but an oversized system can be more prone to having the condenser freeze. Ask This Old House (https://www.youtube.com/watch?v=-33wjzNxgSw ht

  The first time I had my condenser freeze, I called the HVAC company we use and they had me shut off the system for 30 minutes and it started working again. When their tech came out, he found the refrigerant pressure was low so he corrected that and let us know that when it's hot out (105+) don't ask the AC to keep the house at 75 because it will run non-stop and freeze again. That's when I started thinking about buying an oversized system. Thanks for posting this video. It's pretty good, but it raises some questions for me as well (like was the 4 ton system in the video a variable speed system?).
