The 30-Second Verdict
Trane wins on build quality and warranty depth; Rheem wins on price and dealer availability. For Florida's demanding climate, Trane's XV21 variable-capacity system is a top choice — but Rheem's RA20 is competitive at a lower price point.

Frequently Asked Questions
How long does an AC last in Florida?
Florida ACs run nearly year-round, which compresses lifespan. A typical Florida AC lasts 12-18 years vs. 20+ years in northern climates. Premium brands like Trane may reach the high end; budget brands often fall short of 12 years in Florida's demanding conditions.
Does brand matter more than installer in Florida?
Installer quality matters more than brand. A poorly installed Trane will underperform a properly installed Rheem every time. Ask each contractor about their Trane or Rheem certification level and how many systems they've installed in your area.
What SEER rating do I need in Florida?
Florida Building Code requires minimum 15 SEER2 for new split system installations. For year-round comfort and energy savings, 18-21 SEER2 variable-capacity systems pay back the premium within 5-8 years of reduced FPL/Duke bills.
