Florida Power & Light rates have increased significantly over the past several years, and with AC accounting for 40–60% of a typical Palm Beach home's energy use, the stakes are high. These seven strategies are consistently the highest-impact moves our customers make to reduce cooling costs — without giving up comfort.
Every degree below 78°F increases your cooling cost by approximately 3%. Moving from 72°F to 78°F in a Palm Beach home can save $80–$140 per month in peak summer. Use ceiling fans — they make 78°F feel like 72°F. Set to 85°F or higher when away for more than 4 hours.
If your system is 10+ years old, it likely has a SEER rating of 10–13. Modern systems achieve 18–24+ SEER. Replacing a 10-SEER system with a 20-SEER system cuts your cooling cost by up to 50%. In West Palm Beach, where AC runs nearly year-round, the payback period is typically 5–7 years.
The average Florida home loses 20–30% of conditioned air through leaky ductwork — air that escapes into your attic at 140°F+. Professional duct sealing with mastic or Aeroseal technology recovers that wasted energy. It's one of the most cost-effective HVAC investments available, with payback periods often under 3 years.
South Florida attics routinely reach 130–150°F in summer. Inadequate attic insulation allows this heat to radiate into your living spaces, forcing your AC to work constantly against an invisible thermal assault. Current code requires R-38 minimum; upgrading to R-49 or R-60 in Palm Beach County's climate zone provides meaningful returns.
A smart thermostat (Ecobee, Nest) learns your schedule, pre-cools before you arrive, and avoids running the AC hard during FPL's peak demand periods (4–9 PM weekdays). Some models save an average of 26% on heating and cooling costs through smarter scheduling and usage insights.
West-facing windows in a Palm Beach home receive intense afternoon solar gain that pours heat into your home throughout peak afternoon hours. Solar window film (3M, LLumar) blocks 50–80% of solar heat while maintaining visibility — a permanently installed solution that reduces your home's cooling load every day.
A dirty evaporator coil increases energy use by 20–30%. A refrigerant charge that's off by even 10% degrades efficiency significantly. Annual (or better, twice-yearly) professional tune-ups keep your system operating at designed efficiency ratings. The $150–$250 tune-up cost often pays back in energy savings within 2–3 months.
Our team can perform a whole-home energy assessment and recommend the highest-ROI upgrades for your specific home and system.
