Energy Savings Calculator
How much will a customer save by upgrading their system? Show them the dollar figure based on their actual SEER difference, tonnage, and electricity rate.
Enter the current and new system SEER ratings to calculate savings.
What to do with this number
- Build the customer's ROI case. Show the annual savings and payback period during the sales presentation. A $340/year savings on a $7,000 install is a 20-year payback on energy alone — but add reliability, warranty, comfort, and available rebates to complete the picture.
- Show the payback period honestly. Energy savings rarely justify a replacement by themselves. The payback is part of the story, not the whole story. Lead with comfort and reliability, use savings as supporting evidence.
- Know the diminishing returns above SEER 18. Going from 10 to 16 SEER saves far more per dollar than going from 16 to 22. The savings curve flattens. A 16 SEER system may be the better value than a 22 for most customers.
- Revisit when electricity rates change. Florida rates fluctuate. A rate increase makes the savings case stronger. Rerun this calculator with current rates before each sales season.
Savings calculated using DOE EnergyGuide methodology. Actual savings depend on usage patterns, thermostat settings, duct condition, and insulation. Energy savings alone rarely justify an upgrade — reliability, warranty, comfort, and rebates are additional factors.
