tool.hvac-energy-savings Calculator
Calculates annual energy savings from upgrading HVAC equipment to a higher SEER or AFUE rating, and shows the payback period. Each SEER point of improvement cuts cooling energy by roughly 7% — this shows the dollar value of the efficiency gain.
Inputs
Current Seer
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
New Seer
Reference formula or conversion factor shown for context.
Cooling Hours
Reference formula or conversion factor shown for context.
Tonnage
Age in completed years. Many health and fitness formulas adjust for age.
Rate Per Kwh
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Results
annual savings
Total money or resources saved compared to the baseline or alternative scenario.
old AC cost/yr
The total monetary cost computed for the given inputs.
new AC cost/yr
The total monetary cost computed for the given inputs.
energy reduction
Sample size or count used in the calculation.
payback (assuming $4k install)
The arithmetic total of all input values.
SEER
Reference formula or conversion factor shown for context.
