HVAC Energy Savings Calculator compares the annual energy costs of two SEER-rated HVAC systems to help users estimate potential savings. Users input location, system size, equipment costs, climate hours, electricity rates, and system lifespans to generate outputs such as annual operating costs, annual savings, lifetime savings, and payback period. It shows that a higher SEER system is more efficient and saves money over time, with a projected payback and lifetime savings, while noting that results are estimates subject to usage and installation.
