I live in Orlando FL going to buy a whole house ac unit, by not having a heat pump does this help the efficiency of the ac since ac is used more. I like it cold in the winter I know a heat strip uses more energy but never really use the heat. Is a variable contol better than 2 speed motor. An is Payne ac OK vs a Goodman system. Thanks

The install is more important than the brand name.
