Frequently Asked Questions
Is Carrier or Rheem better for Florida humidity?
Carrier's Infinity series with Greenspeed variable-speed technology provides exceptional dehumidification — the system modulates compressor speed to run longer cycles at lower capacity, extracting more moisture per BTU. Rheem's variable speed units are capable but Carrier has a slight edge for coastal and South Florida's extreme humidity.
What AC brand do Florida contractors install most?
Carrier, Lennox, Trane, and Rheem are the most commonly installed brands by Florida HVAC contractors. The brand matters less than the contractor — a well-installed Rheem will outlast a poorly installed Carrier. Focus on finding a NATE-certified FL contractor with good reviews, then ask which brand they service most (parts availability and tech familiarity matter for repairs).
How often does AC need replacing in Florida?
Florida AC systems typically last 12–15 years vs. the national average of 15–20 years, due to year-round operation and heat stress. Signs it's time to replace: frequent repairs costing more than 50% of replacement value, unit is R-22 refrigerant (phased out), efficiency below 14 SEER, comfort issues or high humidity. Don't wait for complete failure — plan proactively.
