While there are plenty of professional fixes for central AC that freezes up, sometimes it's just a combination bad duct airflow, low outside temp, and/or too low thermostat set.

I give it 5 stars because I'm very satisfied with the product. It's precise and well-conceived. It's got a few rough edges, though. (I decided not to deduct a star, because the everything else is so good.)1. Very clever and attractive little plastic case. However, it requires assembly, which takes a bit of time. It is made of 6 precision-cut panels with protective film that you need to peel off. They insert together with tabs. Getting all the tabs in the holes is a fiddly process. If you want...
