HVAC Energy Savings Calculator Description

How HVAC Efficiency Impacts Energy Costs

Heating, Ventilation, and Air Conditioning (HVAC) systems account for nearly 50% of a home's energy use (U.S. Department of Energy). Upgrading to a high-efficiency system can reduce energy consumption by 20-40%. This calculator helps you compare SEER (Seasonal Energy Efficiency Ratio) ratings, fuel types, and regional climate impacts on your HVAC performance.

Understanding SEER Ratings

SEER measures cooling efficiency—higher ratings mean better performance. Modern systems range from 14 SEER (minimum U.S. standard) to 25+ SEER (premium models). According to the EPA, upgrading from a 10 SEER to a 16 SEER unit can save up to 40% on cooling costs.

Real-World Savings Examples

A 2,000 sq. ft. home in Texas with a 16 SEER unit saves ~$300/year compared to a 10 SEER system (ENERGY STAR). Factors like insulation, thermostat settings, and maintenance also play key roles in long-term savings.
