Hi, I've been getting quotes for a split A/C system. My home is 2200 sq ft and I've received a quote for a 4 ton, 13 Seer, Payne heat pump for $4357. Goodman 4 ton, 13 seer, $4800. Amana (same specs) $6500, Trane $6740. What is the best system for the money? I don't need "bells and whistle" just a good system for the weather conditions here in Florida.
