The 30-Second Verdict
Both are premium, dealer-installed brands built for hot climates. Trane is famous for durable, heavy-gauge compressors and tends to score slightly higher on long-term reliability — a real advantage in Florida, where an AC runs nearly year-round. Carrier (which invented modern air conditioning) often edges ahead on top-tier efficiency and quieter variable-speed models, and its Infinity line has excellent humidity control. For most Florida homes the deciding factor is the installer, not the badge: a great local dealer on either brand beats a mediocre install on the other.
