Calculator Inputs
Quick Summary
- Built for: HVAC sales teams, estimators, and budget-focused homeowners.
- Key outputs: Estimated annual kWh (old and new), Estimated annual operating cost (old and new), and more.
- Use this page for early planning estimates before final code and manufacturer verification.
Inputs
- Existing SEER
- Proposed SEER
- Annual cooling hours
- Electricity rate ($/kWh)
- System capacity (tons)
Outputs
- Estimated annual kWh (old and new)
- Estimated annual operating cost (old and new)
- Approximate annual savings
How this calculator estimates results
- Converts system tons and annual cooling hours into yearly cooling BTU demand.
- Estimates annual energy use for existing and proposed SEER using simplified SEER-to-kWh conversion.
- Computes annual operating costs from local electric rate and reports estimated yearly savings.

Common ranges and tips
- Use realistic annual runtime for your climate to avoid over- or under-estimating savings.
- Savings are sensitive to electricity rate and actual installed performance quality.
- Use this estimate for budgeting, then confirm upgrade economics with contractor and manufacturer data.

FAQ
The calculator is designed to estimate upgrade savings, so proposed efficiency needs to exceed the current baseline.
Yes. Annual cooling hours are a major driver of kWh and cost savings in this estimate.
No. Utility bills also include non-cooling loads, rate structures, and system operation differences not modeled here.
Absolutely. Duct leakage, refrigerant charge, airflow, and commissioning quality can materially change real-world savings.
Disclaimer: Use results for planning only. Final design and installation decisions must follow local code and manufacturer documentation.
