SEER Savings Calculator
Estimate your annual energy savings from upgrading to a higher-SEER cooling system.
Rough guide: ~800-1000 hrs mild climates, ~1200-1500 hrs hot/humid climates (Southeast, Southwest), ~600-900 hrs cooler climates. This is a full-load-equivalent estimate, not literal hours the system runs.
U.S. average residential rate is roughly $0.16/kWh as of 2026 — check your utility bill for your actual rate.
This is an estimate using standard energy-savings methodology (the same approach used by ENERGY STAR and utility rebate calculators), not a guarantee. Actual savings depend on your home's insulation, ductwork condition, thermostat settings, and local climate. Browse cooling systems to find a real SEER2-rated replacement.
