Money-Saving Tips:
  • Set thermostat to 78°F (25.5°C) — each degree lower increases cost by ~6%
  • Use ceiling fans with AC — allows raising thermostat by 4°F while maintaining comfort
  • Install programmable/smart thermostat — saves 10-15% automatically
  • Seal windows/doors — prevents cooled air leakage (up to 20% savings)
  • Clean/replace AC filters monthly — dirty filters reduce efficiency by 15%
  • Close blinds/curtains during peak sun hours — reduces heat gain by 30%
  • Schedule annual HVAC maintenance — improves efficiency by 5-10%
Data Sources: Electricity rates based on utility company averages (2026 Q2). SEER ratings reflect US DOE standards. Carbon intensity uses EPA eGRID regional factors (avg 0.42 kg CO₂/kWh for US grid). Actual costs vary by usage patterns, weather, building characteristics, and tariff structures (time-of-use, tiered pricing). This is an estimate — check your utility bill for accurate figures.
