Frequently Asked Questions
Which smart thermostat saves the most on Florida AC bills?
Ecobee typically saves 15–23% on HVAC costs vs. Nest's 10–15%, largely due to its room sensors that prevent over-cooling common areas while under-cooling occupied rooms. In Florida where AC runs 8–10 months/year, a 5–8% difference can represent $150–$300/year in savings on a typical home.
Does FPL or Duke Energy offer smart thermostat rebates in Florida?
FPL (Florida Power & Light) has offered $50–$85 rebates on qualified smart thermostats through their On Call program. Duke Energy Florida has similar demand response programs. Check your specific utility's website — programs change annually and some require enrollment in demand response (allowing utility to temporarily adjust your thermostat during peak demand).
Can a smart thermostat help with Florida humidity?
Yes — Ecobee with its built-in humidity sensor can trigger humidity-reduction mode, running the AC fan longer after cooling cycles to dehumidify. This is valuable in Florida's 70–90% relative humidity. Nest's dehumidification control is more limited unless paired with a whole-home dehumidifier. For serious Florida humidity issues, a standalone whole-home dehumidifier ($1,500–$2,500) combined with a smart thermostat is the most effective solution.
