The SEER Calculator at seercalc.pro helps homeowners calculate potential energy savings when upgrading their HVAC system. Users input their current SEER rating, desired new SEER rating, AC unit size, annual usage hours, electricity rate, and optional upgrade cost. The calculator then provides:
Our calculator uses the industry-standard formula: Annual kWh = (Tonnage × 12,000 BTU × Hours Used) / (SEER Rating × 1,000). We then multiply by your electricity rate to determine annual cost. Savings are calculated by comparing your old system cost to the new system cost.
Upgrading from 10 SEER to 16 SEER (2.5 ton unit, 1200 hours/year, $0.13/kWh): Saves approximately $487 annually, $2,435 over 5 years, $4,870 over 10 years.
Upgrading from 13 SEER to 18 SEER (3 ton unit, 1800 hours/year, $0.15/kWh): Saves approximately $562 annually, $2,810 over 5 years, $5,620 over 10 years.
