I inquired about a higher seer unit when I had my system refreshed recently (I'm not in TX). The company I went with had the opinion that the higher SEER units are harder to diagnose and fix if you end up having a problem. With the way supply chains are right now, getting a less common unit means if you have a problem, and you will because half the components are imported now, you're going to be sweating it out while you wait 3-6 months for a part, and that's if you can find a tech to come out and diagnose it properly. If I lived in the deep south, I'd get whatever the standard equipment is and spend the difference on extra solar panels.
