Frequently Asked Questions
Which AC brand lasts longest in Florida?
All major brands (Carrier, Lennox, Trane, Bryant) have similar 15–20 year design lifespans when properly maintained. In Florida's coastal salt-air environments, ask about polymer-coated coils or request a brand with corrosion-resistant cabinets — this matters more than brand reputation for longevity near the coast.
What SEER2 rating should I get for Florida?
The minimum new-installation SEER2 in Florida (Southeast region) is 15 SEER2. For Florida's year-round usage, higher SEER2 has better payback than colder-climate states — 18–21 SEER2 typically pays back in 5–7 years vs. a 15 SEER2 unit. 24+ SEER2 has a very long payback period and is typically only worthwhile for high-usage households.
Does brand matter for an AC unit?
Brand matters less than installation quality and contractor competency. A well-installed mid-tier system outperforms a poorly installed premium system. Choose a dealer first based on local reputation and service capability, then choose the brand they work with most frequently — their expertise on that brand is more valuable than brand specification differences.
